FURNEAUX, F.R.G.S. WITH 16 COLOURED PLATES AND OVER 500 ILLUSTRATIONS IN THE TEXT LONDON LONGMANS, GREEN, AND CO. AND NEW YORK: 15 EAST 16th STREET 1898 All rights reserved PREFACE 'BoYS WILL BE BOYS How often has this expression been used in extenuation of their mischievous propensities Boys are naturally active, and if they have not the inclination or the opportunity to expend their store of mental and physical energy in some interesting and profitable employment, we shall be sure to find them busily occupied in working out some little scheme by which they hope to derive satisfaction at the expense of their playmates, their neighbours, or some dumb animal. You may almost as well talk to an oak log as tell a boy that he should abstain from such practical jokes as those which give him pleasure at the cost of his victimised school- mates, that it is wrong to annoy his neighbour by damaging his property, or that it is cruel to tie a bundle of ignited crackers to the tail of a cat. If a boy is to relinquish such occupations, we must direct his energies into another channel by giving him a taste for something better. Teach him to play a game of cricket, or to swim ; let him have a camera, and show him how to take a photograph ; give him a sketch-book, and culti- vate a taste for the reproduction of the beautiful in nature and art; or make him a present of a book of scientific recrea- tions. Among such works probably none will be found so fascinating to a boy as those which treat of natural history. Let him once acquire a taste for collecting, preserving, and studying natural history objects, and he has a hobby that will keep him out of mischief, give him healthy employment for mind and body, and occupation for all seasons of the year, both at home and in the field. PREFACE It is with a desire to cultivate such a taste, and to assist our boys (and our girls too for that matter) in the varied em- ployments which constitute the labour of love' of the true naturalist that these pages are written. I was once a boy myself, and well do I remember the many difficulties and disappointments I experienced while endeavouring to make a useful collection of natural objects-difficulties and disappoint- ments which might have been to a great extent obviated by the perusal of a popular yet scientific guide to the various departments of natural history. In presenting the following pages to my readers, I do not hope, nor shall I attempt, to convert them into full-blown naturalists. Many years of the most careful observation, com- bined with much patient work on the part of the student, would be necessary to produce such a result. My only aim is to induce my readers to make a start, and to give them such a general outline of natural history as may form a safe foundation for the future study of any branch of the science that they may desire to follow. The scope of this volume is large compared with its size. It includes a brief survey of the animal kingdom, with numerous hints on the collection, preservation, and classification of specimens.. Many objects which are not generally studied by young collectors are here considered as worthy of a drawer in the young naturalist's cabinet. Thus the reader is made acquainted with the fact that the seaside is not merely a collecting ground for shells and weeds, but that almost every overturned stone between the tide-marks reveals a host of living beings which, although less conspicuous, will repay the time spent in their study. The vegetable kingdom is dealt with in a similar manner. Then follows a short chapter on the collection and arrangement of minerals and fossils. It is hoped that the detailed descriptions given for the construction of the necessary apparatus and the methods of using it, and the abundance of illustrations, will render this work a thoroughly practical guide to the young collector.

PART I ANIMAL LIFE CHAPTER I PONDS AND STREAMS I WILL begin by giving my readers a few hints on the collection of the various forms of animal life to be met with in ponds and streams. Young collectors often neglect the study of pond life. Perhaps this may be accounted for by the fact that most of the inhabitants of the water are not to be seen before they are caught. A butterfly on the wing will always arouse their interest; and, even if it appears to be only a White,' yet the probabilities that it may be a Hawthorn' or a Bath' will often result in the insect being netted for a cursory inspection. But when we stand on the edge of a pond, nothing in particular attracts our attention, unless it may be that the brilliant wings of a dragon-fly fix our gaze. We look at a dense mass of duckweed-a screen so thick that we scarcely hope to find a living creature in the water from which it shuts off the sun's rays. A little careful observation will, however, show us our mistake. A small black and shining body suddenly appears on the surface, displacing some of the little green fronds; and after a few seconds' repose as suddenly disappears again. Soon other signs of life become apparent, and then probably we wish some means were at hand by which we could search the new hunting ground. I can strongly recommend pond hunting to a young naturalist. There is an immense variety of living forms in fresh water. Nearly all these are easily obtained, and generally require but little attention in the aquarium. One single hour spent in pond hunting will supply you with material for interesting occupation at home for many weeks. This form of recreation has the additional advantage PART I ANIMAL LIFE CHAPTER I PONDS AND STREAMS I WILL begin by giving my readers a few hints on the collection of the various forms of animal life to be met with in ponds and streams. Young collectors often neglect the study of pond life. Perhaps this may be accounted for by the fact that most of the inhabitants of the water are not to be seen before they are caught. A butterfly on the wing will always arouse their interest; and, even if it appears to be only a White,' yet the probabilities that it may be a Hawthorn' or a Bath' will often result in the insect being netted for a cursory inspection. But when we stand on the edge of a pond, nothing in particular attracts our attention, unless it may be that the brilliant wings of a dragon-fly fix our gaze. We look at a dense mass of duckweed-a screen so thick that we scarcely hope to find a living creature in the water from which it shuts off the sun's rays. A little careful observation will, however, show us our mistake. A small black and shining body suddenly appears on the surface, displacing some of the little green fronds; and after a few seconds' repose as suddenly disappears again. Soon other signs of life become apparent, and then probably we wish some means were at hand by which we could search the new hunting ground. I can strongly recommend pond hunting to a young naturalist. There is an immense variety of living forms in fresh water. Nearly all these are easily obtained, and generally require but little attention in the aquarium. One single hour spent in pond hunting will supply you with material for interesting occupation at home for many weeks. This form of recreation has the additional advantage ANIMAL LIFE that it may be carried on, if desired, throughout the year. Even in the month of February, when nearly all life is apparently dormant, a dip in a stagnant pool will generally be rewarded with more or less success ; but during the warmer months every haul will bring to view a crowd of living creatures. APPARATUS FOR COLLECTING IN FRESH WATER Many and varied are the appliances recommended by different writers for the capture, conveyance, and preservation of the speci- mens, many being of a somewhat complicated character. But the best of results may be obtained by the use of the most simple appli- ances, such as may be fitted up by the most inexperienced and unskilled. The collector's outfit will consist of a net, a dredging-hook, a dipping-bottle, a can, some wide-mouthed bottles, and a few tin or zinc boxes. As regards the net, this may be home-made or purchased. Where the means are not very limited, a most convenient form of folding net may be bought. This may be carried in the pocket, and readily screwed on to the end of a stick when required for active service. But it is possible that many of my readers may, either for pleasure or from necessity, desire to make their own. I will there- fore give a few hints based on my own experience. For years I have used a net made as follows: Bend a piece of stout iron wire into the form here represented. Push the two straight ends into a piece of strong brass tubing, about three-eighths FIG. 1. FIG. 2. of an inch in internal diameter, and three inches long. Then, by hammering the end of the tube, the wire is held in a firm grip. The other end of the tube receives a tough stick about three or PONDS AND STREAMS . four feet long. A strip of stout calico is now sewn round the iron ring, and to this is attached a net of gauze or book muslin, about eighteen inches deep, conical in form, but with a rounded end. A metal y (fig. 3) may be obtained at the dealer's for a few pence, and with this a net frame may be fitted / up in a very short time. All that is necessary is to bend a piece of cane of suitable diameter, and push it well into. the two narrow arms of the Y. Or a i strong y-shaped twig may be cut, and the ends of a strong cane or piece of wire firmly bound to two of FIG. 3. its arms by fine copper wire; the other arm being provided with a ferrule by which it is attached, when required, to a walking-stick. A dredging-net is often very useful, especially when the ponds or streams to be searched are rather large. This may be simply an ordinary net, the metal frame of which is thicker than usual-say about three-sixteenths of an inch-and flattened on the off side. The net is tied to a strong string four or five yards long. The other end of the string being tied to the wrist, the net is skil- fully thrown out into the water so that it falls flat on the surface, and then pulled in along the bottom. I have often made the same net serve both purposes, changing string for stick, or vice versd, as cir- cumstances required. When the pond is crowded with weeds it may often be an advantage to weight the off side of the net with a piece of lead. During several summers I have paid many visits to a certain favourite pond about eight yards in diameter. Here I have always commenced operations by scraping the banks by means of the stick and net. Then, exchanging stick for string, I have searched the less accessible parts, by which means I have undoubtedly secured many a victim driven from the borders by my previous attacks. The dredging-hook is very useful for collecting the plants which thrive in our ponds, and which add so much to the beauty of our aquaria. It may, I believe, be purchased, but is easily made. Fi. 4. -A Mine consists of three butcher's galvanised meat- DRED)GING-HOOK. hooks soldered together; but they may be bound together by means of copper wire. Soldering is such a useful art that even the naturalist should learn it. Sometimes the ferrule of 12 ANIMAL LIFE his net splits, his bait can springs a leak, or the joint of his y gives way ; and the repairing occupies only a few minutes. A dipping-bottle is exceedingly useful, especially when the collector is the fortunate possessor of a good microscope. It con- sists of a wide-mouthed bottle of medium size, with a spreading rim. A stout wire ring is fastened securely round the neck, and the twisted ends of this serve to fix the arrangement to a stick. Stagnant water usually teems with the lower forms of life, both animal and vegetable; and with the aid of the dipping-bottle samples of water may be collected from different parts of a pond. When it is intended to search for microscopic objects, a hand mag- nifying lens should always form part of the equipment. Each sample of water removed from the pond is held up to the light and examined with the lens. If abundant signs of life are visible, the greater portion is gently poured back into the pond, and the lower richer part, with all its sediment, put into a collecting-bottle for further examination at home. Many interesting low forms of life may be secured by gently scraping the submerged surfaces of piles and other objects. Of course, this may be done by means of the simple dipping- bottle and stick. My own plan, however, which seems to be in every way satisfac- tory, is this: A small tin funnel with a wide tube fits firmly in the cork of a wide-mouthed bottle. Two other holes in the cork are covered with fine muslin ne and a ferrule soldered to a metal band round the neck of the bottle serves to fix I |the whole to a stick. A As the funnel moves upwards in the water, gently scraping the surface to which it is applied, a current of water sets downwards into the bottle, afterwards escaping through the muslin covering the FIGo. 5.-BOTTLE FOR COL- holes in the cork. In this way a large LECTING Low Fo OI s OF quantity of water may be strained through PoND LIFE. the apparatus, while the little living beings passing down the funnel are continually adding to the density of the population. After a time the cork is removed, and the contents poured into PONDS AND STREAMS 5 the collecting-bottle. The little animals and microscopic plants thus collected will afford no end of amusement and instruction for many months. They require no further attention beyond the occasional addition of a little water to replace the loss by evaporation, and they will often be found to increase prodigiously in their new home. The can previously mentioned may be the ordinary angler's bait can, or, as a substitute, a few smaller tin boxes with perforated covers. The perforations need not be many or large, and are easily made by knocking the point of an awl through the metal. These are used for the larger aquatic animals, such as.the newts and tritons. It is quite a mistake to suppose that these require a large supply of water during their transmission. Each box should con- tain a little of some kind of water weed to keep the specimens damp, the weeds themselves being useful for study, and also for stocking the aquaria. Smaller boxes should also be taken for water beetles, larvm, water spiders, &c.; and great care must be taken to isolate the voracious kinds. The carnivorous beetles and larTm should not only be separated from the harmless creatures which they so readily attack, but they themselves should not be crowded together; otherwise the collector may find, on his return, a number of dead insects, some having been even reduced to fragments by the powerful jaws of their fellow-captives. When all the above requisites have been properly prepared, only one thing remains to be done: see that you have provided ample accommodation for the expected enormous and sudden increase of your family. The new abodes may consist of glass jars, tumblers, bell jars, pans, or anything that will hold water. My plan is to keep a large bell jar for the newts and tritons, another for the water beetles and carnivorous larvae, a third for the less voracious insects and water spiders, and a fourth and smaller one for the microscopic specimens. As a rule, small fishes may inhabit the same water as the newts, and aquatic snails may be distributed in all. Pond hunting is not by any means a drawing-room sport, and one must not be too careful about his outward appearance in its pursuit. Most ponds and many streams are surrounded by low, marshy banks; so that it is often impossible to keep oneself free from mire during the search. It is therefore absolutely necessary that the collector be provided with a thick and sound pair of boots, not polished, but well greased. Starched cuffs become an abomina- tion, and even the coat-sleeves will generally acquire a consider- ANIMAL LIFE able accumulation of bottom mud, often black and highly odorous. The young naturalist, therefore, if wise, will leave his 'Sunday clothes' at home, and he will take care to wear a good pair of leather leggings. THE AQUARIUM Perhaps it will be advisable at this stage to give some hints on the selection and management of aquaria. Where the main object of the collector is to become acquainted with aquatic life in all its phases-to obtain as great a variety as possible for purposes of observation and study-the large single aquarium is a great mistake. A number of vessels will have to be provided, in order that the various kinds of animals may be effectually protected from their enemies. But it is not necessary that the vessels be of any parti- cular or fashionable form. Of course, a large aquarium is very serviceable for fishes and newts, but many of the lower forms are much more easily managed in small vessels. For purposes of study one can do nothing better than fix a shelf across a window that is not exposed to the full blaze of the sun, and arrange on this one or two good-sized vessels for the larger specimens, and several smaller ones to contain the others. We can quite understand, however, that a strong desire to possess a larger and really ornamental affair may exist, and then the design and general appearance becomes a most important consideration, especially if the proposed aquarium is to occupy a place in the drawing or dining room. The shape of the vessel is, to a certain extent, a matter of taste ; but as success will be in proportion to the maintenance of natural conditions, we should make it our aim, as far as is consistent with appearance and other circumstances, to imitate the natural pond or stream. All natural waters receive their supply of light from the top only; hence the animals which are kept in the inverted bell-jar aquarium are at once placed in an unnatural condition, for they receive the light from all sides. Yet my own experience shows that this form is not by any means unsatisfactory if properly managed. The rectangular form of aquarium is far preferable to the bell, for it does not magnify and distort the specimens. Such aquaria are rather expensive, but are easily made by those who possess a little mechanical ingenuity. A framework is made by soldering together some pieces of angle zinc.' This may then be soldered to a bottom of sheet zinc, supported on a slab of wood, and the sides PONDS AND STREAMS and ends fixed with a good cement. The ends may be of slate, the front of thick glass, and the back either of glass or slate. The selection and application of the cement, however, requires considerable care, since a very small leakage may prove a great inconvenience, particularly with an indoor aquarium. I have seen scores of recipes for stopping and fixing the glass, and have tried several of them, but still feel doubtful as to which is the best. The following is a good one: Mix two parts each of litharge, plaster of Paris, and very fine sand, and one part of powdered resin. Then make this into a putty with boiled linseed oil and a little driers. This cement will take a few weeks to harden. Some writers recommend an aquarium which widens out at the top; the object being to expose a larger surface of water to the air. I cannot regard this form as a very sightly one, and the necessity for the widened top disappears when the aquarium is properly stocked. It may be observed, however, that all aquaria, of what- ever form, should be wide in proportion to their depth. Now, supposing that the vessel is chosen and procured, how shall we proceed to make the necessary preparations ? First obtain from a neighboring pond or stream a sufficiency of bottom mud to form a layer about two inches deep. I have seen ordinary garden soil recommended for this purpose, but it is more likely that the mud taken from the pond or stream whence we are to obtain our stock of animal and vegetable life will satisfy the requirements of the in- habitants than soil obtained from any other source. We are now ready for the aquatic plants; and here again we must study the requirements of Nature. Some thrive best in swift waters, and others in sluggish streams and pools. The same remark applies also to the animal life, and especially to fishes. Therefore, specimens that have been caught in running water should be kept under the same conditions; and creatures obtained from ponds should not have frequent changes of water. Some aquatic plants have well-developed roots, and require the presence of either a muddy or a sandy soil; others, like the duck- weeds, require no soil, but float on the surface of the water, deriving all their nourishment direct from the air and the water. The former should be properly set in the soil of the aquarium, which is then, if at all muddy, covered with a moderately thick layer of well-washed sand or shingle. The water is now allowed to run in gently till it reaches within an inch or two of the rim. If the side of the aquarium which is turned to a window is of ANIMAL LIFE glass, it may be advisable to cut off much of the light entering at that side. A few rather large stones, loosely piled one on the other, are also useful in providing hiding-places for such animals as require more or less seclusion. It will sometimes be necessary to cover the top of the aquarium with gauze to prevent the escape of some of the captives. Minnows, for example, will often take a vigorous suicidal leap into the air, and developing frogs, leeches, and the pupa of the dragon-fly crawl up the glass above the water. But the watchful aquarium- keeper will soon learn for himself when the gauze covering is necessary. We have now a very important matter to decide. Supposing our aquarium to be stocked with pond life, how often will it be necessary to change the water? Such a question is not to be answered satisfactorily in a few words. We are all acquainted with the ordinary fish-globe,' with its contracted top, stocked with a few gold-fish, and placed on a table or suspended in front of a window by way of ornament. And who has not seen the poor fish skimming the surface of the water and gasping for want of air ? The form of the vessel is such as to prevent the free aeration of the water, and no means have been arranged for a renewal of air. Fishes and all gill-breathing animals are dependent entirely on the supply of air dissolved in the water; and without air they die as we should. This being the case, we should always keep up a sufficiency of dissolved air in an aquarium which contains gill-breathers. Now, this may be done in two or three different ways. There may be frequent changes of water, or the same water may be agrated by some mechanical contrivance; or, thirdly, an appro- priate amount of vegetable life may be introduced to maintain what is called the balance of life. The first of these methods is exceedingly troublesome, especially when the aquarium is small and the demand on the air large; for, in this case, a change may be necessary every day; and, once for- gotten, we are sadly reminded of our neglect by the sight of our lifeless pets floating on the surface. The second method is more satisfactory, but a little ingenuity is required in fitting up the necessary apparatus. Either a current of air is to be forced into the water, or a fine jet of the latter is sent into the air. The better plan is to supply a very fine fountain jet from a small cistern placed high enough to give the PONDS AND STREAMS required pressure. A waste pipe is not necessary, for the little cistern may be refilled with water from the aquarium. Personally, I have no delight in either of the above methods; for, where the lack of vegetable life renders one or the other necessary, the aquarium cannot be a very attractive object. The chief interest doubtless lies in the varied movements and habits of the animated creatures, but the general appearance is due principally to the beau- tiful verdure and the graceful form of the plant life. I will now point out a better way of snrating the water. Pro- bably you know that plants as well as animals require air. But there is this difference: Animals inhale the oxygen that is in the air, and breathe out carbonic acid gas, while green plants take in carbonic acid gas and give out oxygen. If, then, care be taken in regulating the supply of aquatic plants, the animals will provide these plants with carbonic acid gas, and in return will receive from the plants the oxygen that they need; and the water of the aquarium need seldom be changed. I have at the present time three vessels which have had no change of water for over four months, and yet the health of the animal inmates leaves nothing to be desired. An aquarium should be put in a good light, but should never be exposed to the direct rays of the sun for any length of time. Low forms of vegetable life (Confervc) will make their appearance as a green growth on the glass, especially if the light is strong. A little of this does not mar the beauty of the scene at all; but it sometimes becomes so dense as to be almost opaque. This growth may be re- tarded considerably by reducing the intensity of the light. A sheet of white or blue tissue paper pasted on the side of the glass which receives the stronger light will prove very effective. One word more about aquaria: let me recommend you to depart from the old-fashioned plan of stocking your aquarium with a few fish only, as if fishes were the sole inhabitants of the water. Fishes are very interesting, some of them particularly so; but, strange to say, those which exhibit the greatest variety of interesting habits are seldom to be seen in aquaria. The eternal gold-fish is a little overdone. Its colour is too bright when not relieved by a blending of less gaudy tints, to be constantly before one's eyes ; and its movements are monotonous compared with the lively and variable antics of many of our little finny friends. An aquarium should be always a changing scene; and every outing should be the means of providing new items in the entertainment, ANIMAL LIFE MAKING A START We are now on our way, and we naturally inquire, Which are the best kinds of ponds in which to search ? My advice is: 'Try all.' It frequently happens that a most unpromising pond or ditch is full of interesting beings. Sometimes the black mud and brown frothy scmn are very uninviting, and the odour evolved on disturbing the water repels us; yet a few dips may be rewarded by many a beautiful specimen. On the other hand, a pond of clear water, adorned with the lovely flowers and leaves of the water-lily and crowfoot, may be comparatively barren. Frequently we can see the objects we require, and aim straight at them with the net; at other times we dip indiscriminately, and wonder what the result will be. It is not wise, as a rule, to spend much time in walking round a pond merely looking for moving forms at which to strike. Your chances of success are much greater if you are constantly dipping as you go. On reaching the bank of a pond, put out your net as far as you can, and strike the surface of the water perpendicularly with your net. Then drag it in along the bottom, being careful to bring it well home on the vegetation, if any, bordering the banks. Always make for tufts of weeds and submerged grasses, for many animals seek shelter under these, especially after the water has been disturbed by a few strokes of the net. After a few dips, turn out the whole contents of the net-mud, weeds, snails, worms, beetles, larvae, spiders, and a host of other things -on a piece of bare ground; and, after turning up a few inches of your coat-sleeves, proceed to examine the mass most carefully, and put in boxes the specimens selected. LEECHES It is probable that most of my readers do not possess such a luxury as a compound microscope, and for this reason I have thought it advisable to pass over all the interesting microscopic inhabitants of our ponds and streams. This I do with very great reluctance, since these minute creatures are quite as beautiful and just as enter- 'taining as the more conspicuous aquatic animals. Let those who have a microscope make a free use of the dipping-bottle I have de- scribed, and they will find innumerable treasures in the stagnant pool; and even those who have no better magnifier than an ordinary pocket lens may derive much pleasure and profit in watching the movements of these low forms of life, PONDS AND STREAMS We shall start, then, with the leeches, and pass from these to the higher aquatic animals. Several varieties' of leeches inhabit our ponds and streams. They are all soft-bodied animals, divided into a number of ring-like segments like the common earthworm. They are parasites, deriving all their nourishment by sucking the juices from the bodies of living animals. The Horse Leech is very common in our country. Many are the fabulous stories which have been told about this harmless creature, many ignorant persons considering it to be so poisonous that nothing would induce them to handle one. It certainly has teeth, but these are made of gristle only, and could not penetrate the thinnest human skin. Nevertheless, these weapons can easily wound the flesh of the soft-bodied animals on which the leech feeds. It lives principally on worms and grubs; but, failing these, it does not hesitate to suck the blood of its own species. One of my cap- tive leeches was bold enough to enter the shell of a large fresh- water mussel; but it was a fatal venture. The mussel snapped its shells together with a powerful grip that almost severed the leech's body in twain. When the horse leech wishes to swim, it flattens its body into a tape by means of a series of muscles which pass from the upper to the lower surface. It then moves onward with graceful undulating motions. The Medicinal Leech, once common with us, but now rare, is larger than the horse leech, and may be known by the broken Fis. G.-THE MEDICINAL LEECH. yellow bands along its back. Its teeth are hard and sawlike, and are worked with a rasping motion by a set of powerful muscles. It has ten eyes, arranged in one curved line. ANIMAL LIFE FRESH-WATER MOLLUSCS The term 'shell-fish' is so unscientific that perhaps we had better discard it altogether. The various animals included in this category are not fish at all, nor are they even near relatives of the finny tribe. The class name Mollusca is applied to an extensive group of animals, all of which are characterized by a soft body, usually inclosed in one or two shells. Most of them have not the faintest trace of an internal skeleton. The body of a mollusc is covered with a loose, thick, and slimy envelope called the mantle, and this secretes the hard layer of limy substance that forms the shell. A kind of membrane on the floor of the mouth bears, in many species, a large number of little teeth, arranged in regular rows; and FIG 7.-THE TEETH OF these constitute the rasp by which the A MOLLUSC. creature grinds the vegetable matter on which it feeds. Nearly all the molluscs are aquatic, the majority of them inhabiting salt water; but some inhabit fresh water, and must now be briefly considered. The Fresh-water Mussel The fresh-water mussel (Anodon), shown on Plate VIII, is com- mon in some of our ponds and rivers. It is one of the bivalves or two-shelled molluscs, very similar to the common edible mussel in form and appearance, but much superior in size. This creature is easily kept in the aquarium, and is perfectly harmless. Let us watch its movements and habits, after having placed it on a bed of fine sand. At first its shells remain firmly closed, but when it feels itself out of danger it thrusts out from between its valves a fleshy part called its foot. By means of this it slowly turns itself over, and half buries its shells in the sand. As it lies here with its valves gaping, we observe two open tubes slightly protruding, and a very small quantity of carmine or other suitable colouring matter placed gently near the Anodon will prove the existence of two currents of water-one entering and the other leaving its body through these tubes. By this means the gills with which it breathes are being continually bathed with fresh water. PONDS AND STREAMS Fresh-water Snails Fresh-water snails are not only ornamental, but even useful, in the aquarium. Some of them feed on the Conferva-the green vegetation which sometimes covers the sides of the vessel so densely- and consequently help to keep the glass clean. All the snails belong to the Headed Mollusca, a division charac- terised by the possession of a distinct head, with eyes and horns, or feelers. They are all vegetable feeders, and the 'rasp' formed by their numerous small teeth aids them in securing their food. The front portion of this rasp does the chief work, and is, consequently, soon worn down; but the strip of gristle on which the teeth are set is continually growing towards the front, thus renewing the worn part. The shells of snails are coiled into a spiral, due to the unequal growth of the body, one side growing faster than the other. The largest British water-snail is the Paludina (Plate VIII), which sometimes reaches a length of nearly two inches. It is to be found in the quiet nooks of many of our southern rivers, and, less abun- dantly, in other parts. Its eyes are placed on the extremities of short stalks. This snail brings forth its young alive, for the eggs are hatched while yet within the body of the parent. When disturbed it retreats within its shell, and then closes the aperture with a horny lid operculumm), similar to that of periwinkles and whelks. On Plate VIII you will see a figure of another large snail (Limnea stagnalis), which is very common in stagnant pools and sluggish streams; and the common Peregra of the same family, found in similar situations. On the same plate you will also see a repre- sentative of the flat spiral molluscs (Planorbis), of which there are several species. Sometimes water-snails lay their eggs on the glass of the aquarium, in which case the gradual development of the young may be easily watched with the help of a magnifying lens. The table of classification given in the chapter on Snails and Slugs' includes both the terrestrial and aquatic molluscs, and will assist the beginner in the arrangement of his collection of shells. The few hints given in the same place on the preservation of mol- luscs also apply to the aquatic species. ANIMAL LIFE FRESH-WATER CRUSTACEANS Before examining the fresh-water species of this group it will be well to learn the general characteristics by which we may recog- nise its members. The bodies of all the Crustacea are composed of a number of ring-like segments jointed together, all the segments being constructed more or less on the same general plan. Each segment bears a pair of limbs. Sometimes two or more of these rings are fused together so completely that the divisions are no longer to be seen; bu in such cases the limbs always remain quite distinct, and thus reveal the true or original number. The Crus- taceans have no internal bony skeleton, but are protected by a skin which has either become horny, or else hardened by limy substance. Our common aquatic species include the Crayfish, the Fresh- water Shrimp, Water-fleas, and Cyclops. The Crayfish The River Crayfish (Astacus fluviatilis), which closely re- sembles the common lobster, is plentiful in many of our rivers. Its skin is hardened by carbonate of lime, which is extracted from the FIG. 8.-THE CRAYISII. water ; and as this condition is absolutely necessary for the preser- vation of the animal, we find crayfishes abounding most in the rivers of limestone districts. During the winter crayfishes spend much of their time in bur- rows which they excavate, or in natural crevices in the banks of the streams ; and large numbers may sometimes be dug out of these hiding-places during the cold weather. In milder weather they PONDS AND STRfEAMS watch for their prey at the months of their burrows with horns ex- tended, but dart backward with a rapid flap of their powerful tails when danger threatens them. In summer they may be seen walking about in shallow water during the cool hours of the evening, but they hide themselves during the heat of the day. FIG. 0.-THE CRAYFISH (UNDER-SUlFACE). Crayfishes are to be caught in a variety of ways. Baskets baited with frogs or pieces of meat may be let down into the water and hauled up at intervals. Like moths, they are said to be attracted by lights during the night, and are then easily caught with a net. But the most exciting mode of capture is that of wading in the river and pulling the creatures out of their hiding-places by the horns; also turning over the stones and chasing the retreating crayfish as 16 ANIMAL LIFE it smartly flaps its tail with its face to the foe. This is the only method I have tried myself, and recommend it as being a very amusing and lively sport, especially as it often affords an opportunity of testing the power of the creature's claws. We frequently meet with crayfishes having a limb much less than its proper size. This is generally the result of a fight-a kind of sport in which crayfishes seem to derive as much pleasure as some men. Again, if a limb is seriously injured, the animal snaps it off at one of the joints above the seat of injury ; or, if caught by one of its limbs, it will often voluntarily amputate that limb, and rapidly retreat, leaving an inconsiderable portion of its body wriggling in the hands of its captor. In either case a new limb is developed, and at last becomes almost, if not quite, as large as the original. The best way to keep crayfishes alive is to put them in a very shallow trough with a supply of running water, and some loosely piled stones to afford them hiding-places. As to diet, they are not at all fastidious. They will dispose of water plants, carrots, turnips, cabbage stalks, and other vegetables with a relish. But they are not strict vegetarians by any means, for they will devour snails (shells included), fish, meat, or poultry. The old hard and limy skin thrown off during a moult' is crushed in the animal's jaws, and utilised in the formation of a new coat of armour. The female crayfish will even devour her own offspring; and, yet more horrible, the male will kill and eat his own spouse I Other Crustaccans Every young collector who has tried his luck in small streams must have met with the lively little Fresh-water Shrimp. A number of these should be put into the aquarium for observation, not only because their movements are interesting, but also on account of their usefulness as scavengers. They are not at all particular as to diet, and greedily devour all kinds of decomposing matter that would tend to make the water putrid. In structure they rather closely resemble their salt-water cousins -lobsters, shrimps, and prawns-and, like the females of these marine relatives, the fresh-water shrimp carries her eggs under her abdomen. If you examine the water that has been dipped out of a stagnant pool by simply holding it up to the light, you are almost sure to see a number of little creatures, varying in size from a sixth of an inch downwards, darting about actively in all directions. These are the Water-fleas and Cyclops, both of which may be kept in an ordinary PONDS AND STREAMS bottle for a great length of time without the slightest attention, and be examined at leisure with a magnifying glass. It must not be supposed that the water-flea is in any way related to the obnoxious FIG. 10.-A WATER-FLEA, FIG. 11.-A CYCLOPS MAGNIFIED. CARRYING ITS EGG-SACS. parasite of a similar name, for both it and the cyclops are crustaceans, while the flea is an insect. WATER SPIDERS AND MITES Spiders and Mites, together with various other small creeping and flying creatures, are often regarded as belonging to the insect world, but in reality they form quite a distinct class (the Arachnidae), differing from all insects in several important particulars. If you examine a spider, you will see that its body is composed of two dis- tinct parts. The foremost division consists of the head and thorax (chest) combined, and the large and globular hinder portion-the abdomen-is joined to this by a very slender waist. Spiders may also be distinguished by their four pairs of legs. They all breathe by means of a system of air-tubes, which communicate direct with the atmosphere. The eyes, which are not compound like those of insects, are arranged in little clusters on the front of the head. If the reader will compare these few characteristics with those of insects (p. 20), he will at once perceive the reason for the separa- tion of the two creatures into distinct divisions of the animal kingdom. ANIMAL LIFE The most interesting of the water spiders is undoubtedly the Argonaut or Argyroneta, more commonly known as the water spider. This creature was at one time quite plentiful, but is now compara- tively scarce, owing, it is said, to the vigorous search made for it by naturalists and the 'dealers.' We can quite understand that the disclosures of the wonderful instincts of this spider would make it 4 FIa. 12.-WATER SPIDERS. quite a pet with aquarium-keepers, but perhaps a lesson may be learned from its almost wholesale destruction. .The Argyroneta may sometimes be found among the contents of the net, but it is also to be seen exploring the banks of ponds and streams in search of food. It constructs a dome-shaped cell of silk beneath the surface of the water. This cell is moored to water plants by means of silk threads, and is fixed with its mouth downwards, PONDS AND STREAMS just after the fashion of a diving-bell. Having finished the construc- tion of this little dwelling, it rises to the surface, and thrusts the tip of its abdomen out of the water. Then, by a sharp snap of its hindermost legs, it detaches a bubble of air; and, holding this securely between its limbs and its hairy body, it descends to the dome, looking like a ball of silver as it goes down, thrusts its abdo- men under the rim, and sets the bubble free. The air is at once caught in the cell, and, after about a dozen such journeys, sufficient has been collected to supply the spider's wants. The argonaut feeds on all kinds of aquatic insects, and sometimes travels considerable distances from home in search of its prey, but always returns to its dome to suck the juices of its victim. The meal being over, it rests awhile with its head downwards, thus exposing the breathing tubes of its abdomen to the air, and at the same time keeping strict guard over its habitation. The eggs of the argonaut are laid in a silken cocoon at the top of the dome; and here the young; about a hundred in number, remain till they are strong enough to construct domes for themselves. Other water spiders frequent our ponds and sluggish streams, but none of them construct a sub-aquatic home like the species above described. Mites resemble spiders in form, and may generally be Q /W\A known by their four -pairs of ' legs; but some of them, during their earlier stages, are seen with only two or three pairs of' I limbs properly developed. These little creatures are sometimes seen swimming freely in the pFe. 13.-WATER MITE, water, or creeping along the HIGHLY MAGNIFIED. leaves and stems of the water weeds; but some of them, especially when young, are unable to get about without assistance, so they attach themselves to the bodies of water beetles and water scorpions, thus obtaining a very con- venient ride at an extremely low fare. ANIMAL LIFE FRESH-WATER INSECTS We now come to the class Insecta, the most numerous and the most highly developed of all the animals without backbones. These are so widely distributed that it is almost impossible to find a place in which they do not live. The summer air is full of their hum; every little pond harbors its thousands, every crevice in the soil or the solid rock provides them shelter, every tree and shrub supplies them with food; and many seek shelter in the habitation of man. The term insect is applied by the uninitiated alike to all small animals. Spiders, mites, centipedes, and woodlice are all popularly known as insects. But let us see what an insect really is. The name is derived from two Latin words which signify cut into,' and itself marks one of the chief distinguishing characteristics of the whole class, for the bodies of all insects are distinctly divided into three parts-the head, the thorax, and the abdomen-and the de- pression between these parts is often so deep that they appear to be connected by a mere thread. Look, for instance, at the very slender neck of the house-fly, and the thin waist of the wasp. Insects also undergo changes of form (metamorphoses). Thus, from the egg is hatched the larva or grub. This, when full grown, changes into the pupa, or chrysalis, from which emerges the imago, or perfect insect. The larvre, as a rule, are voracious feeders, and grow very rapidly, undergoing a series of moults or changes of skin. When fully grown they cease to eat, and, after casting their skins for the last time, change into the pupal state, usually concealing themselves underground, or in a cocoon of silk or other material which they construct for their protection. The pupa is usually very inactive, and eats nothing ; but a change is gradually taking place within it, for the organs of the perfect in- sect are in process of formation. At last the time arrives for the final metamorphosis. It breaks its loosened skin, struggles out of its burrow or cocoon, and seeks a place where it can expand and dry its wings. It is now the perfect insect or imago, endowed usually with enormous powers of flight, and capable of propagating its kind. The perfect insect has always three pairs of legs, one pair being appended to each of the three segments which form the thorax. PONDS AND STREAMS Many, like flies and gnats, have but one pair of wings, always jointed to the middle segment of the thorax. Others, such as butterflies and moths, possess two pairs, attached to the second and third seg- ments. Others, again, like fleas and lice, have no well-developed wings for flying. All insects have one h pair of antennae, with some, very conspicuous and exquisitely formed, - but with others, so small as to escape .1 general observation. F Insects are further k characterized by the peculiarity of their breathing apparatus, which consists of a set of air-tubes called tra- chece, kept open by an elastic thread coiled spirally, just like the wire in an india-rubber gas-pipe, and communi- eating with the outside air by openings in the skin called spiracles.

It is a jointed animal, with a body of three divisions, undergoing metamorphoses, having always three pairs of legs in the perfect state, and breathing by means of trachea. Water Bugs We will start our observations on the aquatic insects with a brief notice of the Water Bugs (Hydrocorisa). These have very short ANIMAL LIFE antennae, almost concealed beneath the eyes. The front legs are not very long, and are capable of being folded in such a manner as to be useful in seizing and holding their prey. The family of Water Boatmen (Notonectidre) is very well known, especially the Common Boatman (Notonecta glauca), which may be found among the net haulings from ponds ahlost everywhere. These insects are happily named, for they are decidedly boat-shaped, and the hind legs, which are about twice as long as the others, stand out at right angles like the oars of a boat, and are provided with fringes of stiff bristles for blades. The Latin name is also well applied, for Notonecta means FIG. 15.-WATER BOATMAN back swimmer,' and all the members of (Glauca). the family swim on their backs. These insects should be watched in the aqua-. rium, for their movements are extremely interesting. They pad- dle themselves about with great activity, always nicely feathering' their oars by depressing the bristles after every stroke. When taken out of the water they act very clumsily, sometimes walking with their four short legs, and dragging their oars behind them, and often giving a succession of leaps by a sharp motion of the latter. During the night they often leap out of the water and take short flights from pond to pond. The boatman is a carnivorous insect, feeding on any living thing which it is strong enough to conquer. It holds its prey firmly with its front legs, and, after stinging it to death with its sharp beak, proceeds to suck its juices till nothing is left but an empty skin. The beak is also used as a weapon of defence, as I have proved many times when holding these creatures in the hand. It will pierce the skin, producing a sharp pain like the sting of a bee, but not so intense. It breathes by means of an air cavity between the wings and the upper surface of the body, and often reposes on its back with the tip of the abdomen just above the water, so as to allow this cavity to communicate with the atmosphere. Sometimes, however, it will seek another experience by turning itself over and basking in the hot sun with its back out of the water. The boatman spends all its three stages in the water. The larva and pupa both resemble the perfect insect in general form, but the PONDS AND STREAMS larva has no wings, and those of the pupa are imperfectly developed. The eggs may be found in spring on the leaves of water plants, and the young larve are hatched in April or May. The Corixa is very similar to the Notonecta in form and habits, but is not nearly so common. FIG. 16.- Corixa, Fio. 17.-THE WATER SLIGHTLY ENLARGED. SCORPION. The Water Scorpion (Nepa cinerea) forms a bold contrast to the pretty and active boatman. It is a very unsightly and sluggish creature, delighting in stagnant and foetid waters. The term scor- pion has been applied to it on account of the scorpion-like appear- ance of the front pair of legs, which are bent round towards the mouth to serve as a pair of pincers. Its body is flat and leaf-like, and of a colour resembling that of the mud in which it lies concealed when watching for its prey. When the water scorpion is at rest you will notice that it is either on the mud in very shallow water, or on water plants near the surface, with its long and pointed 'tail' thrust upwards so that the end projects out into the air. This 'tail' is really a pair of grooved rods, which, when placed together, form the creature's breathing tube. The scorpion does not eat its prey, but sucks out all the juices from its body. I have before me, as I write, a vessel containing about a dozen water scorpions, and about the same number of the dead larve of the dragon-fly. The latter have been killed by the scorpions, and their dead bodies, which have not lost their original form, have been sucked till they are transparent. Our next example of the water bugs (Ranatra linearis) is quite a graceful object compared with the ugly Nepa. It is also 24 ANIMAL LIFE far more active, and will sometimes boldly defend itself against its enemies. All insects have very light bodies, and even in cases where the build seems bulky and heavy, a great deal of the interior is occupied Fia. 18.-Ranatra. by air-sacs and air-tubes. A certain group of the bugs (Hydro- metridce) have bodies so very light that they actually run on the FIG. 19.-A WATER GNAT (Hydrometra argentata), MAGNIFIED. FiG. 20.-WATER GNAT (H. gibbifera), ENLARGED. surface. These are the Water Gnats, which we see during the sum- mer in almost every pond. Let us catch one of them, and examine its wonderful feet. The microscope shows that they are covered with fine velvety hairs. - 6 Plate. I. I AlunM~ PONDS AND STREAMS which, like the feathers of the duck, will not become wet, and are resisted by the water beneath them with sufficient force to support the body of the owner. As we watch them on the water we observe that they run on two legs as we do, using for this purpose the middle pair. The front legs are always held out in readiness to seize their prey, and the hind pair, projecting backwards, form the steering gear. Some of the water gnats fly well, and when they alight on the surface of the water they may be seen folding their hind mem- branous wings, and tucking them snugly under the front horny pair with their legs. Aquatic Nerve-winged Insects This order, the Neuroptera or Nerve-winged Insects, is so named on account of the delicate network of nervures which sup- port the transparent membrane of the wings, giving them a beautiful lace-like appearance. The group includes the beautiful Dragon-flies (Libellulce), with wings of such delicacy, and colours so brilliant, as to make them in no wise inferior to the butterflies in beauty. In many parts they are known as horse-flies or horse-stingers, on the supposition that they are guilty of annoying horses and cattle; but this is wrong, for they live entirely on insects, and have no occasion to attack quadrupeds. Several species inhabit our country, some of which are shown on Plate I, but they resemble each other so closely in structure and habits that the following account applies almost equally to all. The larvae may be dredged out of our ponds, where they lie concealed in the mud, with their large and prominent eyes on the look-out for their prey. Their jaws are covered with a peculiar ' mask,' which can be thrust out till it is about half the length of the body. This mask is really an enlarged lower lip, extending back- wards on the front lower portion of the thorax, and is provided with a pair of jaws or pincers, with which the larva seizes its prey. Thus the creature can lie motionless and unseen in the mud, and seize its unwary victims by simply shooting out its mask. These larvae have a very remarkable breathing apparatus, which serves also as a means of locomotion. The breathing cavity lies along the back of the abdomen, and if you watch one at rest you can see this cavity pulsating regularly. But now disturb it, and it will make a sudden dart without moving a limb, just as if it had ANIMAL LIFE been pushed on by some magic force. Now put the larva in a glass of clear water with very fine sand at the bottom, and you will notice that each time the creature darts forward a little cloud of sand is shot backward. Thus the secret is revealed: the larva suddenly contracts its breathing cavity, forcibly ejecting the water it contained, and the recoil starts the body in the opposite direction. The pupa of the dragon-fly is very similar in appearance to the larva, but may be distinguished at once by the short imperfect wings. FIG. 21.-LARVA OF DRAGON-FLY, SHOWING THE MASK, AND THE PERFECT INSECT EMERGING FROM THE PUPA-CASE. Unlike most pupse, it retains the voracious habits of the larva. After the dragon-fly has spent about eleven months in its two preparatory stages, living all the time in water, it climbs up the stem of a water-weed to prepare for its final change. Here the pupal skin splits along the back, and the perfect insect gradually works itself out of its old coat, and leaves it still attached by the claws to the plant. The perfect fly now remains suspended on the weed till its beautiful wings have expanded and dried. This does PONDS AND STREAMS not take long, and, as soon as the wings are sufficiently stiff, the dragon-fly begins its short aerial life. The flight of some of the larger dragon-flies is so rapid that it is very difficult to catch them on the wing. They dart about, chasing, tearing to pieces, and devouring all kinds of insects. They have the remarkable power of suddenly reversing the action of their wings, so that they can stop quickly and dart backward in the air. The jaws of the dragon-fly are very powerful. It will allow itself to be fed while held in the hand by the wings, but probably it is anger rather than hunger that prompts it, for it will savagely chew up small sticks and straw when brought within its reach. FlI. 22.-THE MAY-FLY. Fri. 23.-LARVA or THE MAY-FLY. FIG. 24.-PUPA OF THE MAY-FLY. The May-fly (of the family Ephiemeridce) has a life-history very similar to that of the dragon-fly, but there are a few interesting points of difference which we will briefly note. The eggs of this insect are allowed to fall into the water, all being united into one little mass. The larva burrows into the mud at the bottom of the ANIMAL LIFE pond or stream, and there feeds on decayed vegetable matter. If you require these larve for the aquarium, you must dredge in some of the pond mud with your net; or you may stir up the mud with a stick, and then capture the larve which have been driven out with the net. After spending about two years in the larval and pupal states, the insect leaves the water towards the close of a day. Its skin then splits along the back, and out comes a rather heavy-flying insect, which is called the false-imago, and settles at once on the bark of a neighboring tree. Here it rests for a time, after which the second skin splits, and from it escapes the perfect and active little May-fly, leaving the false' skin still attached to the tree. The perfect May- fly has no mouth, and requires no food, for it is destined to live for a few hours only It joins the merry company over the water's edge, and dances during the evening twilight with an incessant up-and- down motion. Before the sun rises in the morning it has finished its frolicking, deposited its little cluster of eggs, and fallen dead, with all its playmates of the previous evening, either on the water or near its edge. It has lived two years in its preparatory stages, but in its perfect form it has, perhaps, not taken one single peep at the sun. Fro. 25.-CADDIS-FLIES. Our last example is the Caddis-fly, known also as the Cad, Grannum, and Cockspur. This is well known to anglers, for both the larva and the perfect insect are admirable for bait. The fly itself is not swift on the wing like the dragon-fly, but it runs quickly, and it can do this even on the surface of water. The chief interest, however, lies in the larva, which constructs a home for itself out of materials found in the water. It cements together pieces of stick, sand, shells, dead leaves &c. into a little tubular habitation suffi- PONDS AND STREAMS ciently long to completely cover its body. Then the larva, knowing that its soft, fat, white body is highly prized as a delicacy by the fishes and predacious larve, never ventures to expose any portion save its hard head and its legs; but this is sufficient to enable it to walk about, while the claspers at its hinder extremity serve to fix it to its 'case.' Very interesting experiments may be performed to test the building powers of the caddis larva. If you pull a few of them gently FIG. 26.-CADDIS CASES. out of their homes and place them in a clean glass of water, they will construct new ones before your eyes, and of any material you may please to give them. In this way I have obtained pretty little tubes composed of glass beads, small pins, shells, &c. Aquatic Two-winged Insects This order (Diptera) contains a large number of insects, all of which possess two transparent and veined wings. The hind pair of wings is not in reality absent, but only imperfectly developed. If you catch one of these creatures-the common blow-fly or daddy- long-legs, for example-you will easily make out a pair of rod-like and knobbed structures just behind the bases of the wings. These are the halteres or balancers, supposed to be of great assistance in regulating the flight, and are the representatives of the hind pair of wings in other insects. The Diptera are further distinguished by the size of the eyes. These are always very large comparatively, and, in some instances, certainly make up the greater part of the head. Most of the two-winged insects are inhabitants of the land and air only, but a few very interesting species are more or less aquatic in their habits, and will therefore be best considered now. The troublesome little gnat (Culex pipiens) is a well-known example. Let us look briefly into its wonderful structure and ANIMAL LIFE history. Catch one of these sportive little creatures and place it under the microscope, and you cannot but regard it with wonder. Even the instrument with which it wounds us is sure to call forth our admiration. The exquisitely tinted scales which adorn the wings and the beautiful feathered antennae of the male are always favourite objects with microscopists. The male gnat is a perfectly harmless fellow; but look at the instrument of torture that arms his mate. It is a little case, consisting of two parts, and containing a bundle of lancets which can not only pierce through our skin, but also inject an irritating liquid into the wound. If you want to study the life-history of the gnat you need go no farther than the open water-butt. Here you may see Mrs. Gnat with her fore legs on a floating straw or weed, her middle legs resting on the water, and her hind legs carefully arrang- ing her new-laid eggs into the form of a little boat. One by one she lays the eggs and glues them together. When she has finished Fro. 27.-EGGs OF her labours you may examine the little float- THE GNAT, MAGNIFIED. ing boat. Ruffle the surface of the water and it will not turn over. Turn it completely over and it will immediately right itself again. So here it remains on the surface, probably deriving benefit from its double exposure to air and water. Shortly the young .larve appear, and you may observe their transparent bodies at the top of the water, with the breathing tubes just above the surface. When fully grown the larva changes to the pupa. It is now a very different creature. Its back is hunped, and the hump is raised slightly out of the water, for it has now discarded its old breathing tube, and receives its air supply by means of two appendages on its back. It does not eat, nor could it if it wished, for its pupal skin completely covers its mouth. Yet it is active, and may be seen wriggling about in the water, alternately straightening and bending its body. Now comes the final transformation scene. The pupa raises its back out of the water. The portion of the skin thus exposed be- comes dry and splits. The rent enlarges rapidly, and the dry skin opens so as to form a little boat. Little by little the perfect gnat emerges from its torn garment-first the head, then the thorax, and finally its abdomen. The gnat now raises its body till it looks as if the boat were supplied with mast and sail. Then it leans over and rests its front legs on the surface of the water, which is sufficiently PONDS AND STREAMS firm to support its fragile body. Watch it a little longer and you can see its wings expand. Soon they are dry and rigid, and in a moment the gnat is frolicking in the air. "0- 'dAl -\\ .' I-\ FIG. 28.-THE STAGES OF THE GNAT, SHOWING THE LARVA, PUPA, PERFECT INSECT EMERGING, AND MALE AND FEMALE FLYING. ANIMAL LIFE Aquatic Beetles The Coleoptera, or Horny-winged Insects, are well represented in our ponds and streams. Dip your net into any weedy pool, and you will almost invariably turn out a few species of water beetles.' Put them all in a tin box or can with plenty of wet weed-no water being necessary for their transmission-and, on arriving-home, throw the whole into a large vessel of water, and observe them at your leisure. You will probably find among them species ranging from about a twelfth of an inch to considerably over an inch in length. Observe how actively they dart about. Their bodies are smooth and boat-shaped, so that they are enabled to move through the water with but little resistance. The hind legs are long and fringed, and are used exactly after the fashion of a pair of oars. Take one of the insects in your hand, and gently lift up the horny outer wings (the elytra), and beneath will be seen the neatly folded transparent wings used in flying. Notice, too, their powerful horizontal jaws, and you will not be surprised at their voracity. You may feed them on worms, fishes, frogs, insects, or any kind of meat, raw or cooked; but, if not well supplied, they will soon take to eating one another. The water beetles generally remain in the pools and streams throughout the day, but often make long excursions from one patch of water to another during the night. In some cases their flight is somewhat lofty, and when they find themselves vertically over a favourable piece of water, they seem to.let themselves drop into it. Many a water beetle has been deceived on a clear night by the re- flection of the moon's rays from glass, and has fallen with a crash on the roof of a greenhouse. The finest of our carnivorous water beetles is the Great Water Beetle (Dyticus marginalis), a very interesting object for the aquarium. It is very common in ponds, and its voracious larva may be dredged in with the mud and weeds. Those who keep the Dyticus in captivity must remember its nocturnal habits. If the aquarium contains much floating weed, the insect can get a foothold to enable it to start its flight; but this may be prevented by a covering of gauze. The attitude of Dyticus when at rest is a curious one. When undisturbed it keeps at the surface, with its head in- clined towards the bottom, and the tip of its abdomen just a little out of the water, and thus it remains perfectly still, resting on its oars.' It is watching for some dainty morsel with which to satisfy its keen appetite. But why this curious attitude ? When the beetle PONDS AND STREAMS dives beneath the surface you will observe a bubble of air entangled between the tip of the abdomen and the elytra, shining in a strong light like a globule of quicksilver. This is the supply of air for its respiration, and must, of course, be renewed at frequent intervals; but as long as the Dyticus remains at rest with its hinder extremity just out of the water, there is a free communication between the outer air and the breathing space beneath the elytra. When you grasp a Dyticus in your hand, you will almost invari- ably find it endeavouring to slip backward between your fingers, and, unless your skin is moderately thick, you will probably learn why. There are a couple of sharp spines underneath the abdomen close to the hind legs. These are directed backward, and are thus rendered serviceable by the movement of the beetle just mentioned. Fia. 29.-Dyticus marginalis, Fro. 30.-Dyticus marginalis, MALE. FEMALE. It has another peculiar means of defence. When irritated it dis- charges a whitish fluid, of a very disagreeable odour; should any of this touch the skin, something more than an ordinary wash will be necessary to remove the objectionable perfume. The larva attains a length of about two inches, and may be kept in the same aquarium as the perfect insect. In ponds it often lies concealed in the mud, and, being of much the same colour as this mud, it is not easily seen by the unwary beings who live in danger of its hungry jaws. It breathes by means of a pair of fringes wh'ch you will observe at the end of its tail. When it dives beneath the surface it carries down a small supply of air entangled among the hairs of this fringe; but it often rests at the surface in an inclined position like the perfect insect, with the tail-fringe projecting a little above the water. The larva is as voracious as the perfect form, and D ANIMAL LIFE by means of its hollow jaws it will suck the juices of its victims, leaving little more than an empty skin. When about to change to the pupa, it creeps up the bank of the pond, burrows into the damp earth, and constructs a little oval cell Fia. 31.-LARvA OF Dyticus. FiG. 32.-PUPA OF Dyticus. in which to conceal itself. If the weather is genial, it emerges as a perfect Dyticus in about three weeks; but if the winter winds are near at hand it takes a long nap in the pupal state, postponing its final change till the warmth of the spring sun penetrates into its cell. Fia. 33.-Agabus biguttatus, FIG. 34.-Pelobius Hermanni, MAGNIFIED. MAGNIFIED. The Dyticus may be taken as a type of its family (the Dyticidce), two other members of which are figured (figs. 33 and 34); but our limited space will not admit of even a short description. There is another family of carnivorous water beetles-the Gyri- nida-so named from their peculiar habit of whirling round and PONDS AND STREAMS round on the surface of the water. The best known among these is the common Whirligig (Gyrinus natator), a little beetle, only a quarter of an inch long, and of a blue-black colour. The whirligigs are gregarious, and little com- panies of them may often be seen dancing a merry round in some sheltered corner of a pond. They feed on smaller insects, but are themselves the prey of the birds above and the fishes below. In order to compensate .. for this twofold peril, their eyes - are divided so that they look like four. With the upper divi. FIr. 35.- T FI. 36.-LAv. sions they watch for enemies WHIRLIGI.

Threaten them from above, and they dive rapidly to the bottom; but if in danger of some evil-disposed fish below, they jump up (-~) FrI. 37.-Piceus, M FIG. 38.-LARVA OF PiceUS, NOT IALE. FULLY GROWN. FI,. 39.--PUPA OF PiiceCls. from their liquid playground and take to their wings. The larva, shown in fig. 86, may be dredged out of ponds, and the cocoon may ANIMAL LIFE be seen plentifully towards the end of summer, attached to the leaves and stems of water plants. Our last example of the water beetles is the Black Water Beetle (Hydrous piceus). This one is even larger than Dyticus; in fact, it is the largest of all the British Coleoptera, with the exception of the beautiful stag.' It was once very plentiful in ponds and streams round London; but, being perfectly harmless to animal life, it has become quite a pet with aquarium-keepers; and the consequent demand for it has led to such a vigorous search on the part of the dealers who call themselves naturalists, that scarcely a specimen is now to be found. The female Piceus is provided with a spinning apparatus at the tip of her abdomen; with this she constructs a turnip-shaped cocoon on the stem of a water plant, in which she deposits about fifty eggs. As soon as the young larve are hatched they make for the water, where they feed on molluscs and other aquatic animals till they attain a length of three inches. FRESH-WATER FISHES All the species of aquatic animals .which we have described belong to the great division Invertebrata-animals without back- bones; and, in passing onward from the insects to the fishes, we leave this division for the Vertebrata, or animals possessing back- bones. Perhaps, then, at this stage, we cannot do better than spend a short time in noting the chief characteristics which dis- tinguish these two primary groups of the animal world. None of the beings previously mentioned have internal skeletons; but the Vertebrata, which include fishes, amphibians, reptiles, birds, and mammals or milk-giving animals, all have some kind of internal framework, the chief part of which is termed the backbone or vertebral column. This vertebral column generally consists of a large number of separate bones (vertebrae) placed together end to end, thus forming a long, flexible axis, extending throughout the length of the trunk of the body. The backbone, being hollow, forms a kind of tube, through which a great nerve (the spinal cord) proceeds from the base of the brain. In the Vertebrates, too, we observe a great cavity in front of (or below) the backbone-the cavity which holds the organs of digestion and circulation; while in the Invertebrate animals, with no bony PONDS AND STREAMS column, the nervous system (if any) has no separate tube, but shares the great cavity with the various internal organs. Fishes constitute the lowest class of the vertebrates. They are all aquatic animals, and their structure is, in all cases, peculiarly adapted for their native element. The round-bodied fishes always taper at both ends, and the flat-bodied species always present sharp edges to the water as they move along; and thus the resistance offered to their movements is but slight. Beneath the backbone, in the fore part of the body, are a number of ribs, arranged in pairs, surrounding the internal organs. The limbs are fanlike fins, usually four in number, and arranged in pairs, corresponding with the two pairs of limbs in the higher verte- d FmI. 40.-SKELETON OF A FISH (PERCH). d, dorsal fins; v, ventral fin ; a, anal fin; p, pectoral fin ; t, tail fin. rates. Besides these there are fin rays extending along the back, and also on the under-surface; but these are not to be regarded as limbs, since they are merely extensions of the outer skin. Fishes are all cold-blooded animals, their bodies being always approximately of the same temperature as the water in which they live. The heart consists of two divisions: one, the auricle, receiving the blood from the veins; and the other, the ventricle, pumping the blood to all parts of the body. At each circulation a portion of the blood is forced through the gills for the purpose of being aerated. Everyone has observed that fishes, while alive and in water, are, apparently, drinking without intermission; but the water taken in at the mouth at each gulp does not pass into the stomach with the ANIMAL LIFE food: it is discharged through wide slits immediately at the back of the head. In these slits are placed the gills--fringe-like organs, richly supplied with blood- vessels, and consequently of a deep red colour. Here the blood is separated from the water by only a very thin and transparent membrane-so thin, --.-----. 5 indeed, that the dissolved air ....... c. which the water contains is readily absorbed into the vital fluid. Thus all fishes, together with the gill-breathing inverte- brates, are provided with an apparatus by means of which air is filtered from water, but ----. which is not capable of effectu- ally aerating the blood when in ..Uv direct contact with the free air. Some fishes live entirely at the bottom of their watery home, deriving their food from smaller animals which conceal themselves among the stones, nmud, and weeds; but others are always suspended in the water, and feed on beings which swim about as freely as them- selves. The former are heavier than water, and could not rise to the surface without some effort. The latter, however, are of the same specific gravity as the water; and are, moreover, provided with an air-bladder, by which they are enabled to regulate their specific gravity according to the density of the water at any particular depth FIG. 41.--OGANS OF A FIsn (CARP). at which they desire to swim br, gills; c, heart; f, liver; in, swimming or rest. bladder; ci, intestine. PONDS AND STREAMS The young fishes come from eggs, which are laid in enormous numbers. It has been calculated that the roe of a single fish some- times contains over a million eggs, and that if all the eggs of the various species (more than twelve thousand in number) were to develop into mature animals, our seas and rivers would soon become so thicldy populated that they would have no room to move. But, thanks to their numerous enemies, the greatest of which are the fishes themselves, the majority of the young are devoured, and our waters are thus prevented from becoming stagnant masses of writhing and seething beings, struggling for the last share of food and air. Fishes for the Aquarium Some of our fresh-water fishes thrive well in the aquarium, and become very tame and interesting pets. They should always have plenty of room, and, if you are to be very successful in their management, you must keep them in their natural conditions as near as possible. In all cases give them a liberal supply of growing weeds. Those you catch in still ponds need seldom have a change of water; but the captives from rapid streams should have running water. See, too, that they are provided with their favourite hiding-places. Some like thick tufts of weeds; others prefer to hide in rocky holes, while several seek shelter under the stones of a rugged bottom. All such points as these may be easily settled by a careful observation of the fishes in their haunts. One more general observation: Give your pets their natural food when you can, but never more than is necessary. Flies, grubs, and worms are favourite dainties with nearly all; but, failing these, you may try fresh meat chopped very small, and an occasional sprinkling of flour paste. You must remember, however, that all excess of food will decompose in the water, rendering it putrid and poisonous. Many of our fresh-water fishes belong to the Carp family (Cypri- nide), and of these the Common Carp may be taken as a type. This fish (Cyprinus ca/rmio) was once very rare in this country, and was probably introduced from the Continent. It attains a length of twelve or fifteen inches, and is exceedingly prolific, the number of eggs in a single roe numbering over half a million. It inhabits deep holes in the sluggish parts of our streams, and also thrives well in ponds. Its food consists of worms and insects, and, with these as bait, the carp is easily caught. In winter it lies concealed in the ANIMAL LIFE mud at the bottom. This fish is very much desired for the aquarium and small ponds, especially as it can be easily tamed. The Golden Carp, or Gold-fish (Cyprinus auratus), is apparently a universal favourite with aquarium-keepers. It was originally ' ,. 42-T', H, I A- FIG. 42.--THE CWIP. introduced from China, and has now become so far acclimatised that it does well in our ornamental waters. The Minnow is deservedly a favourite, for it is not only one of our prettiest river fishes, but is hardy and easily tamed. Fi(. 43.-TiE MINNOW. Several other members of the carp family do well in captivity; but, unless your aquarium is a very large one, you must be satisfied with young specimens only. The Gudgeon, Roach, Dace, and Bleak FIG. 44.--THE GUDGrEON. are not difficult to manage, and their bright silvery scales will give a pleasing contrast to the other fishes. PONDS AND STREAMS The common Loach (Cobilis barbatula) does not seem to be so well known, nor have its interesting habits secured for it the popu- larity it deserves as an aquarium pet. A few years since I caught a few small loach in a stream at the southern end of Epping Forest. Fio. 45.-THE ROACH. lI''. 47.-THIE BLEAK. V FIG. 48.-THE LOACH. These I placed in my aquarium and was greatly pleased with their movements. They are very heavy fish, and spend much of their time at rest on the bottom ; but often would they rise to the surface, and, after dragging themselves on to the floating leaves of a water-lily, ANIMAL LIFE somewhat after the manner of a seal when landing, they would bask in the hot sunshine with their bodies partly out of the water. In a very few days they became so tame that they readily took their food from the hand. The loach is a slimy fish, with six barbules at the month. It may be caught by dragging a strong net along the bottom. Of all the British fresh-water fishes none is so interesting as the common Stickleback (Gasterosteus aculeatus), known popularly as the Tittlebat, Tittlebrat, or the Tittler. There are several species of sticklebacks, readily distinguished from each other by the number of spines in the dorsal fin. The term gasterosteus applied to all signifies bone-bellied, and is given on account of the bony bands which form a kind of coat of armour beneath. In addition to the spines of the back, there are the two formidable weapons of the breast (pectoral) fins, which, like the others, can be raised or de- pressed at pleasure. The commonest species has three spines on the back; another-a fresh-water fish-has ten; and a third, which inhabits salt water, no less than fifteen dorsal spines. Sticklebacks are easily kept in an aquarium, but they are very pugnacious creatures, and must have plenty of* space, or the ' survival of the fittest' will be demonstrated to perfection in a very short time. Should you wish to closely observe the habits of these interesting creatures your best plan will be to secure one or two males, and a dozen or so females, early in March, and transfer them to a large glass aquarium, or, which is quite as good, a large tub. Give them a plentiful supply of gravel or sand, and introduce some pond weeds of any description. During the greater part of the year the males and females are hardly to be distinguished from each other, both being of a dull greyish brown colour; but, as the breeding season approaches, the male gradually assumes the brilliant colours which have earned for him such names as Soldier and Fiery.' His eyes then become bright green; the back also assumes a brilliant green colour, and the under-surface becomes bright red. This change takes place in March or early April, and at this time the male stickleback sets busily about domestic affairs. His first work is to prepare a nest for the coming brood. In some cases this nest is composed entirely of vegetable fibres, which he has collected and woven into a kind of cylinder or barrel, open at both ends, and so short that, when occupied by the parent, both head and tail may be seen exposed. Sometimes, however, the nest is simply a hollow PONDS AND STREAMS 48 scooped out in sand or mud, and covered over with interlacing vegetable fibres. Seeing that the stickleback has no building tool except his mouth, and no cement save the slime from his own body, we are bound to admit that great credit is due to him for the clever manner in which he prepares his snug little nursery. The nest finished, his next business is to seek his mate. Having met with a suitable bride, he induces her to enter the nest, some- times, it is said, even resorting to force when his affections meet with no encouragement. As soon as the female has deposited her eggs she is turned out of the nest, and the master immediately starts FIG. 49.-THE THREE-SPINED STICKLEBACK AND NEST. in search of another mate, who is called in to take the place of the outcast. This is repeated till the male is satisfied that the supply of eggs is proportionate to the accommodation. He then closes the ends of the nest, and rigidly guards it till the eggs are hatched, and the young are strong enough to be allowed to roam into the world. During the whole of this time the male 'tittler' will furiously charge all the creatures, including even the larger fishes of the pond or stream, who are so rash as to pass within a foot or so of the nest. But as soon as the young have gone to shift for themselves, and the duties of the nursery are thus brought to an end, he gradually loses much of his pugnacity, and at the same time his brilliant colours slowly fade away, to reappear in the following spring. If you want to catch the Bullhead, known in parts as the Miller's ANIMAL LIFE Thumb and the Tom Cull, you must look out for a shallow and rapid stream with a pebbly bed. Raise some of the larger pebbles, one by one, and at the same moment sweep your net rapidly towards it against the stream. In this way you may obtain several in a. very 'C, Fin. 50. --THE BULLHEAD. few minutes. You may keep these in your aquarium, but you will not see much of them, for nearly the whole of their time is spent in their hiding-places, and they seldom come out excepting when they make a dash at their prey, or shuffle their heavy bodies from one stone to another. Their food consists chiefly of insects and fresh- water shrimps. AMPHIBIANS We cannot take leave of our ponds and ditches without devoting a little of our space to the interesting amphibious animals-animals which, although not strictly aquatic, yet spend more or less of their existence in the water. These include the Newts or Efts, Frogs, and Toads. Their life-history is as full of romance as is that of some insects. They begin life as little fish-like creatures, spending the whole of their infant period in the water, breathing by means of external fringe- like gills. In this stage they further resemble fishes in the posses- sion of a two-chambered heart, and they also own a pair of air-sacs which correspond with the air-bladder of the fish. But as they ad- vance in life a series of wonderful changes takes place, the fish-like form gradually developing into a creeping or jumping quadruped. PONDS AND STREAMS The external gills slowly disappear and give place to an internal pair hidden in clefts behind the head. But even these have only a transitory existence, for they soon vanish and pass their function over to a pair of true lungs which have been gradually evolved from the air-sacs above mentioned. At the same time other transforma- tions have been progressing. The two-chambered heart has deve- loped into a more complicated organ with three cavities; the limbs have slowly made their appearance, first one pair, then another; and the original tail has, in some families, been slowly but entirely absorbed, while in others it has developed into a large, useful, and ornamental appendage. The skeletons of the higher Amphibians are well developed, the build of the limbs in particular bearing a close resemblance to that of the highest animals. The ribs, however, are either very short or entirely absent. The Amphibians, like fishes, are all cold-blooded animals, and the blood is remarkable for the comparatively large size of the cells (corpuscles) which it contains, those of the frog being one eight- FIG. 51.-THE BLOOD- FIG. 52.-THE HEART OF CELLS OF THE FROG, THE FROG. HIGHLY MAGNIFIED. o, anricles : ventricle. hundredth part of an inch in diameter. Small as these bodies really are, yet they are large compared with the corresponding corpuscles in the blood of other animals. The circulation of the blood in the Amphibian may easily be traced. The upper portion of the heart consists of two chambers-the auricles. One of these receives the purified blood from the lungs, and the other the blood from all other parts. Both are continually forcing this into the SSome of the lower amphibians are entirely limbless. ANIMAL LIFE lower division-the ventricle-by a series of contractions or pulsa- tions. The ventricle, in a similar manner, forces the blood through the whole circulatory system, some passing to the lungs for an additional air-supply, and the rest penetrating and bathing the other structures. Thus in each circulation only a part of the blood of the Amphibian is aerated. We will now examine briefly the commonest of the British Amphibians- Newts or Efts There are but two common species of Newts in our country, and both these are more or less known by schoolboys, who speak of them generally as Effers or Effets. I have also frequently heard them called Lizards, especially when they have been seen wandering about on dry land. They are certainly much like lizards in general form, but may always be distinguished from these by the softness and colour of the skin. I have met with many who suppose that newts are never to be seen out of the water. But it is a fact that they spend much more of their existence out of water than they do in it. When on land, however, they always seek cool and shady places; while lizards delight to bask in the hot sun, spreading out their flattened bodies so as to expose a larger surface to his rays. Strange tales have been and are still being told about the venomous and fiery character of newts. Some of our country folk aver that they can spit fire, even immediately on quitting the water; others tell horrible tales concerning the victims who have succumbed from the effects of their poisonous fangs; and, according to the accounts of others, many are the cattle that have been poisoned through drinking the water of ponds and troughs which were inhabited by newts. The country cottager who has lived out his threescore-and-ten in close proximity to a pond annually fre- quented by these dreaded Amnphibians seems to be as ignorant about them as anyone ; and on more than one occasion have such individuals looked at me with terror, and most earnestly entreated me to desist while I have been engaged in collecting newts; and the fear-stricken countenance has given place to an expression of wonder when, after careful watching, it was observed that the venom had had apparently no effect. But, in spite of all that has been- said, the newts remain, as ever, perfectly harmless and exceedingly pretty animals. They have no fangs and will not bite. Even if they did bite, they could not possibly do the slightest harm. PONDS AND STREAMS The Great Warty Newt (Triton cristahts) is a beautiful creature, sometimes attaining a length of over six inches. Its skin is covered with little wart-like projections, and is marked with a number of pores. The tail is flattened at the sides. The upper surface is of a varied dark brown; on the sides are rows of white dots, and silvery bands usually adorn the tail. But the chief beauty of the warty newt is the bright yellow under-surface, which is boldly patched with black. The female is rather larger than her mate, and the FIG. 53.-THE GREAT WARTY NEWT. Rledlncd in size. latter has a beautiful waved crest along the back to the end of the tail. It is only during the breeding season, however, that the crest is to be seen in its fullest development ; for it disappears slowly, but ahnost entirely, as this period closes and the summer approaches. This newt hibernates during the winter months, and for the whole of this time the lungs are inactive, the creature deriving the small air-supply necessary for its indolent existence through its skin. In March it takes to the water, and the best time to secure it for observation in the aquarium is-towards the end of that month. Early in April the female Cristatus lays her eggs, depositing them singly on the leaves of water plants, and carefully covering up each one by rolling the leaf round it with its paws. The egg is globular, ANIMAL LIFE and consists of a capsule, in which the white yelk floats in a colour- less liquid. Outside the capsule is a covering of gelatinous substance, by which the egg is fixed to the leaf. In three or four weeks the young newt-known at this period as the tadpole-eats its way out of its prison, and starts life in perfect independence. In about three months the legs begin to appear-the fore pair first; but it is at least six months before the tadpole has completed all its metamorphoses. In September all the newts, old and young, leave the water and seek a safe hiding-place in some snug hole or corner where several lie huddled together, occasionally straying abroad in suitable weather in search of food. The young newt does not return to the water till it is just three years old, at which age we may look upon it as having reached maturity; but it is not fully grown till the end of the fourth year. ---Li __ ^"-U--- FIG. 54.-THE SMOOTH NEWT. These creatures are very interesting in the aquarium, where they may be fed on worms; and they will not, as a rule, interfere with other inhabitants. It is necessary that they should be provided with a landing-place where they can find a shelter quite out of the water. The common Smooth Newt (Lophlinus punctatus) is much smaller than the last, seldom exceeding four inches in length. Its PONDS AND STREAMS skin is quite smooth. The colour of the male is light brownish-grey above, spotted irregularly with black; beneath it is light yellow, which changes to a brilliant orange, also spotted with black, in the breeding season. The male is crested at this time, and is then a beautiful creature. The female is only slightly spotted, and is not nearly so pretty as the male. The growth and habits of this newt are very similar to those of FIG.-55.-STAGES IN THE LIFE OF A FROG. the last. Both species cast their skins at apparently irregular periods. It is very interesting to watch this operation. As a rule, the whole skin comes off in one piece, and the tiny gloves from off the feet are quite perfect in form, though as delicate as the finest gossamer. I have preserved a few of these cast skins in dilute spirit, and find them in excellent preservation after several years. 0 * I U# ANIMAL LIFE Frogs Those who desire to watch the development of the Frog (lRana temporaria), and to observe its habits, should begin by collecting the eggs, which may be found in abundance in almost every pond. Early in the spring the frogs quit their winter quarters and make for the ponds, where they remain at rest during the day with "---- '* '-- < ? .- : -,l '. -.- -- '.": :' ".--- .' ~ b _LL . V ------~100 FIo. 56.--Tin Co:Mrox Fioc.' heads just out of the water. During the night, however, they are full of activity, and the air resounds with their music. About the middle of March the female deposits her eggs at the bottom of the pond. These are little black globular bodies, each surrounded by a covering of transparent gelatinous substance, the whole forming one irregular mass. The gelatinous envelopes soon swell up enormously by absorbing water, and then the mass rises to the surface, where it remains till the larvae escape. In a few days 2R71 PONDS AND STREAMS the black embryo elongates and gradually assumes a fish-like form, and may be seen moving about in the middle of its case. A few days more and the eggs are hatched. The newly emerged tadpoles are very active little creatures of gregarious habits. They attach themselves to pond weeds by means of little suckers just beside their mouths, frequently changing their positions in the social gathering. At this stage they are vegetarians, feeding on conferve and other low vegetable forms. As they gra- dually assume the adult form, they lose their gregarious tendencies, and swim about freely by means of the undulations of their flattened and fringed tails. In their subsequent metamorphoses they differ from newts in that the hind legs are the first to appear, and also in the gradual absorption and ultimate disappearance of the tail. On reaching the adult form they leave the water, and spend the remainder of the summer in the neighbourhood of the ponds, and feed entirely on insects, worms, and other small animals. A few of the structural peculiarities of the frog are worthy of notice. A well-developed web extends between the five long and slender toes of the hind feet ; but the fore feet, which have only four toes, are not webbed. The drums of the ears are conspicuous be- hind the eyes on each side. The tongue, which is often used to I seize the smaller insects on which it feeds, is attached to the front of the mouth with its tip extending ' backward. The teeth are veryJ small, and consist of a single row in the upper jaw and two small clusters on the roof of the mouth. FIo. 57.-THE TONGUE O" THE The breathing of the frog is Fioo. performed exactly on the principle of a pair of bellows. At the nostrils are placed a pair of valves which open inward, and the contraction of the muscular floor of the mouth forces air into the lungs. Thus the frog may be choked by keeping its mouth open, for the air can no longer be forced into the lungs. Toads Many persons do not seem to know the difference between a toad and a frog, and thus it is we hear the name of one so commonly E2 ANIMAL LIFE applied to the other. Yet the distinguishing features of these amphibians are so obvious that the common error is almost inexcusable. The build of toads is very bulky and comparatively clumsy, and the dull-coloured skin, instead of being smooth and slimy, is drier and thickly covered with warts or pimples. The toads, moreover, do not leap like frogs, but walk slowly with a very awkward gait. The hind legs also are much shorter, and the hind feet only slightly webbed. They have no teeth either in the jaws or in the palate, and the gape of the mouth is much wider than in frogs. FI(. 58.-THE COMMON TOAD. The metamorphoses of toads are very similar to those of the frog, but the eggs are generally laid a few weeks later, and are fastened together in long double chains, instead of in irregular masses. The tadpoles are also smaller than those of the frog. Dreadful and wonderful tales are told and believed concerning this unfortunate creature. Its poisoned fangs, its venomous skin, its fire-spitting propensities, the magic virtue and curative power of the jewel in its head, and its enormous longevity are all accepted as indisputable facts, except by those who have kept and closely observed the toad, and thoroughly investigated into the alarming and startling reports. There is certainly some small sprinkling of PONDS AND STREAMS truth in the statements made concerning its venomous character, for its skin does certainly excrete an irritating fluid which is undoubtedly harmful to certain animals ; but, while the toad is thus protected from the hungry jaws of animals to whom the frog is a luxurious morsel, the poison remains perfectly harmless to the human skin. The Common Toad (Bufo vulgaris) is easily domesticated, and its habits-especially its mode of capturing and devouring its prey- are very interesting. Its partiality for all kinds of insects has long caused it to be regarded with favour by florists. The Natterjack (Bufo calamnita) is not nearly so widely distri- buted as B. vulgaris, but is rather common in certain localities. It may be known at once by the olive tint of its skin, and by the pale yellow stripe running down the middle of the back. It is also more active than its relative, and does not attain to the same large size. PRESERVATION OF AQUATIC ANIMALS It will now be desirable to dwell for a short time on the different methods of preserving our aquatic specimens, and on the arrange- ment of these into a useful collection for future study. In many cases the real animal cannot be satisfactorily preserved, but some non-living portion of its structure, which may in itself be exceedingly instructive, and in many instances beautiful, can easily be kept permanently intact. Soft animals, and soft parts of animals, may generally be pre- served indefinitely in spirit of wine. But it must be remembered that this liquid has a great attraction for water; and, consequently, if the specimen be very soft and contain much water, the spirit will extract a quantity of the moisture, thus causing it to shrivel up till it is hardly recognisable. Again, pure spirit is never necessary for mere preservation, being equally effective for this purpose when mixed with its own volume of water. My own plan is to keep a stock of small wide- mouthed bottles, fitted with good corks ; also a supply of diluted spirit. It is then no trouble to bottle any specimen that is likely to prove useful in the future, either for a museum collection or for dissection. In this way one may soon get a useful collection of molluscs, crustaceans, fishes, amphibians, &c., always in good con- dition for examination when occasion requires. All the winged insects caught in and about the water should find a place in the reader's collection. Instructions are given for killing ANIMAL LIFE and setting' these in the part devoted to Insect Hunting. The water beetles in particular are well worth the trouble. Some of these may be set' with their wings folded as we generally see them, while others may have their wings expanded as in flying. Most of their larvae are rather soft-bodied, and cannot be dried with- out losing their natural form. These are best preserved in diluted spirit, and stored in small bottles or specimen tubes. See that every specimen is properly and fully labelled, and that it stands in its correct position with regard to the others. Each drawer or box should be marked outside with the name of the class or order to which its contents belong; and beneath each specimen should be placed a label containing its name, locality, date, and any other particulars considered sufficiently interesting. How to prepare the Skeleton of a Frog Among the various objects in a naturalist's museum, few, if any, will be more instructive than the collection of bones illustrating the comparative build of the various animal frameworks. But whence is such a collection to be obtained ? There are several methods of preparing the skeletons of small animals, but all of them entail operations of a more or less tedious and disagreeable character. This, however, is nothing to the enthusiastic naturalist, who allows no trifle to stand between himself and his anticipated prize. But even those who have not sufficient enthusiasm to set them to work at bone-cleaning may still hope to acquire a moderate collection of useful specimens, which have already been prepared for them by the natural decomposition of the softer parts of dead animals, aided by the industry of nature's scavengers-the insects. I have many useful specimens, some of them complete skeletons in good condition, which have been simply picked up from the spots where their former owners died. But the naturalist does not restrict himself to this haphazard means of collecting his bones. He aims at obtaining a good typical collection, as far as his means and his leisure allow, and finds it useful to know how to set to work to obtain a complete skeleton, in good condition, of any small animal. We will now see how this is to be done in the case of the frog, reminding the reader that the instructions given will apply almost equally well to all the vertebrate animals of our ponds and streams. First kill the frog, if alive, by shutting it in a vessel with a piece of blotting-paper that has been moistened with a few drops of PONDS AND STREAMS chloroform, and then lay it out on a board. With a sharp knife in the right hand, and a pair of forceps in the left, cut away the skin and abdominal walls, and remove all the internal organs, baing very careful not to injure any of the bones or cartilages. After the body-cavity has been cleared of its contents, the muscles of the trunk and limbs may be attacked in a similar manner ; but the white ligaments that bind the bones together at the joints must not be cut. When the skeleton has been roughly cleaned in this way it may be put aside out of doors, in a dish of water, in some spot where the unpleasant odours arising from the decomposition of the little animal matter that re- mains can give no offence. At intervals of a few days a gentle stream of water should be allowed to play upon it, to remove any refuse, and loose pieces of the perishable Fm. 59.---SKELETON OF THE FROG. matter should be removed with the forceps or a soft brush. When, at last, everything has decomposed with the exception of the bones, the cartilages, and the ligaments, the skeleton may be gently removed from the water, set in some natural position, and then allowed to dry. When quite dry, any of the parts which may have become detached from the general framework may be fastened in their proper places with a little glue or cement. ANIMAL LIFE CHAPTER II INSECTS AND INSECT HUNTING MANY of our insects have already been alluded to, but up to the present we have confined our attention to the resident population and the frequenters of our ponds and streams. We must now see what can be done in other quarters; so for a time we quit the miry banks and odorous mud, and wander through lanes and woods, and try our luck in meadows and waste places. Our work now is strictly entomological-that is, confined entirely to the insect world. So we will set to work till we have put together all the necessary paraphernalia, and then start off delighted with the thought that we have at last been metamorphosed into real live entomologists. The entomologist has a happy time of it, for there is no doubt that he has selected for his study some of the most beautiful of all animated beings; and he is continually finding something that is entirely new to him. Some insects are said to be positively ugly; others we regard as extremely noxious to our persons; others, again, earn our enmity for their extensive damages to our crops. But we must put aside all such prejudices, if we would make ourselves acquainted with the wonderful habits and marvellous structures and metamorphoses of the chief divisions of the insect world. A true entomologist finds delight in the study of all insects. None are too small to attract his attention. If the naked eye fails to detect any beauty of form or colour, he knows that his lens will at once change the appearance. He is not content to study the creatures of the air, but searches diligently for the creeping inhabi- tants of the earth, turning them out of all kinds of chinks and crannies, and digging them out from their homes in the soil. We will now proceed to study a few of the most popular orders. INSECTS AND INSECT HUNTING SCALY-WINGED INSECTS We shall first take the Lepidoptera, or scaly-winged insects, by far the most beautiful of all the insect world, and the favourites of all entomologists. The four wings which constitute the chief beauty of the perfect insects of this group are more or less covered with little scales of exquisite form, and generally exhibit a wonderful variety of colour. Everyone has observed the mealy dust which is so easily removed from the wings of Butterflies and Moths when these creatures are handled. These dust particles are the scales FIG. 00.--SCALES FROM THE WINGS OF BUTTERFLIES. which form the characteristic feature of the Lepidoptera, and it is only necessary to collect a little of this on a slip of glass, and examine it under a microscope, to satisfy oneself as to the extreme beauty of the wings. The head is furnished with a.pair of antennae, which are undoubtedly connected with one or more of the senses of the insect. There is also a very delicate proboscis, or sucker, by means of which the sweet juices of flowers are imbibed. This can be rolled up into a spiral when not in use. The structure of this organ is really a wonder, for, although it is about as fine as a hair, yet it consists of two separate pieces, each one finely grooved, and the two are locked together from end to end by means of a fringe of ANIMAL LIFE minute hairs so as to form an air-tight tube. The eyes are large and rounded, and looking ahnost all ways at the same time; and the number of lenses sometimes amounts to nearly two thousand in a single eye. In addition to these e compound eyes there are two simple eyes or ocelli situated on the top of 1, the head, but these are generally so S' thickly covered with down that they probably have but little to do with vision. 1 The sole work of the perfect butterfly and moth is the repro- duction of their kind. The females always lay their eggs on the food- plants of the larva, and it is astonishing with what precision the proper vegetation is selected in pre- ference to all others. We could Fmo. 61.- HEAI OF A Morn. Understand this habit of the mater- a, upper lip; b, nmandliblps ; c, 1p0- boscis; d, under lip; e, Uitciea; nal parent if she herself derived any ?ye. direct benefit from the same plant as that which sustains her offspring; but it generally happens that none of the sweets of her life are to be obtained from the food-plants she so carefully selects, and she cannot possibly settle on them except for the one special purpose of providing for her progeny. Very soon after this work is accom- plished the parent dies, and this generally before the eggs are hatched. The eggs of butterflies and moths are beautiful objects for the microscope ; and, as they require no special preparation of any kind, the least expert microscopist is not denied the opportunity of witness- ing their beautifully sculptured forms and delicate tints. During the summer months a great variety of eggs may be obtained by search- ing the leaves in our gardens, and these may be examined in site as opaque objects, throwing a good light on them from above. The time which elapses before the appearance of the larva varies accord- ing to the time of the year. Eggs laid in spring take longer to hatch than those laid during the summer months, and those laid in the fall of the year do not hatch till the following spring. When the time arrives for the appearance of the young larva, they gnaw their way out of the shell, and sometimes even devour INSECTS AND INSECT HUNTING entirely the little case from which they emerge. They are now sur- rounded by abundance of food, and right well do they make use of it, for they often eat as much as three times their own weight of food during the first twenty-four hours of their existence, and continue to live after this riotous fashion during the weeks or months of the larval life. In this state they undergo several moultings, for they grow so fast that their old coats become tight and uncomfortable. When about to cast its skin, a larva will cease eating for a time, and seek out some secluded spot until its little trouble is over. At last the tightened skin splits and begins to peel off, and the larva, after many twitchings and twirlings of its uncomfortable body, manages to creep out of its old garment, and to show itself in its new and often differently coloured suit. The body of the larva or caterpillar consists of thirteen segments, including the head. Three pairs of legs are appended to the second, third, and fourth segments, and a variable mnuber of claspers to the hinder joints, usually making up a total of sixteen limbs. Many of them are furnished with a silk-spinning apparatus which is attached to the lower lip. The period during which the Lepidoptera remain in the pupal condition varies considerably. In some cases this is a few days only, but in others the time extends over several months, including per- haps the whole of the winter and spring. The pupa is sometimes naked and hidden in the earth; sometimes concealed in a cocoon of earth, silk, moss, chipped bark, or fragments of mortar from an old wall; some are suspended by the tail, and secured by a silk cord round the middle ; and others are rolled up in leaves and well secured from their enemies by numerous silk bands or fibres. In the pupal state life sometimes seems quite dormant, and the length of time thus spent seems to depend entirely on the temperature. Thus the emergence of the perfect insect may be delayed for months or even years by prolonged exposure to cold, or may be hastened by placing the pupa in a warm situation. One of the most interesting sights ever witnessed by a naturalist is the gradual unfolding and developing of the wings of a newly emerged butterfly or moth. Shortly before this event takes place the tint of the chrysalis is seen to change, the colour of the wings and body often showing itself through the half-transparent case. At last the thin shell breaks, and the perfected insect returns to the world in which it spent its early life as a crawling grub. It is soon free from its prison cell, and immediately seeks some rising surface, up which it creeps. Here, if possible, it selects the under-side of ANIMAL LIFE some branch or ledge, and fixes itself with its back downwards to dry its body and expand its wings. At first it is a queer-looking creature, its wings short and dumpy, more like a pair of useless ex- crescences than the richly ornamented pinions into which they are soon to develop. As we watch the insect closely we observe the wings expand irregularly till they present quite a crumpled appear- ance. At last they straighten themselves out till they have reached their full size. The insect, however, remains stationary, for the newly developed wings, the nervures of which are just filled with currents of fluid from the body, are very 'i moist, and so soft and flexible that they bend Back on the body if the insect turns over. But after a few hours the wings are dry and rigid, and after sundry flutterings, as if to test the mechanism of the new flying apparatus, the insect starts its aerial life. Very few persons, excepting those who delight in the appellation 'Entomologist,' know the difference between a butterfly and Fro. 62.--MOTH a moth. Some appear to base their distinct. JUST EMEREDEI. JU EERED. tion on the brilliancy of the plumage of the wings; but, since many of the moths are adorned with gaudy colours while some of the butterflies are posi- tively dingy, we must consider them quite wrong in their nomen- clature. Others have the idea that the nocturnal habits of the moths are sufficient as a distinguishing characteristic, not knowing that several species of these insects delight in the midday sun. It is true that the butterflies are generally more brightly coloured than moths; also that all the butterflies are day flyers, while most of the moths are nocturnal; but there is one distinguishing mark which can never lead us astray: the antenna of all butterflies terminate in little knobs or clubs,' while those of the other Lepidopte.ra taper to a point. There are yet other differences which, although not to be taken as absolute, are of sufficient interest to note. Butterflies, when at rest, usually raise their wings perpendicularly, pressing them together over their backs ; but moths either spread out their wings horizontally, or bring them close over their bodies, often folding the hinder pair quite out of sight beneath the fore wings. Again, moths generally curve their antenna backward under the head and thorax -a feat which is impossible with the rigid horns of butterflies. INSECTS AND INSECT HUNTING Catching Butterflies The apparatus required for this part of the entomologist's work is simple and small in amount. A net, a killing bottle, a col- lecting box, and a supply of pins of various sizes are all that are required. The net should be of gauze, preferably of a green colour, about twelve or fifteen inches in diameter, with a light but strong frame. As a general rule the entomologist does not require to keep many of his insects alive, and consequently finds it convenient to take with him some arrangement with which he can perform the happy de- spatch.' This is, to my mind, the only unpleasant part of his work. And even though some authorities give it as their opinion that insects cannot feel pain, yet we should always act as if we were sure they could, and kill the insects required, and no more, in the most humane manner possible. There are many methods of killing insects, each method having its devoted advocates; so I cannot do better than mention a few of those most commonly used, leaving the reader to try any or all of them, and so be in a position to decide on a plan that suits himself. At the same time, having given all the methods here mentioned a very fair trial myself, I will give my own experiences, and my opinions as to their relative value in my hands. The first I will mention is the cyanide bottle.' This is simply an ordinary wide- mouthed bottle, such as is used to contain pomades and other similar luxuries, not less than four or five inches in height, into which is put some potassium cyanide with an absor- bent material. The cyanide bottle may be purchased of the naturalist ready for use, or it may be easily fitted up by anyone. The potassium cyanide may be bought at the chemist's, providing he knows you and is satis. FIG. 3.--THE fled as to your intentions; but it is a deadly CYANIDE BOTTLE poison, and must be used with considerable caution. Dissolve a few drams of the cyanide in a little water, and add slowly, with constant stirring, sufficient plaster of Paris to convert it into a thin paste. Pour this at once into the bottle ANIMAL LIFE and leave it to set.' Close the bottle with a good cork, and it is then ready for use. A cyanide bottle prepared in this manner will retain its power for a great length of time if kept tightly corked. Some entomologists dispense with the plaster, and put a few pieces of the cyanide into the bottle, keeping them in place with a few thicknesses of blotting-paper cut to the proper size. This, I think, is not nearly so good a plan, for the paper and cyanide are easily shaken out of their position, and may then seriously damage the insects. Chloroform, benzole, and ammonia are often used for killing insects. In either case a few drops of the liquid should be thrown on to some absorbent material in the bottom of the bottle just before it is required for use; but it should not be used in such quantity as to wet the insects, especially if ammonia is chosen, for this liquid will injure the colour of many specimens and completely spoil them. Both chloroform and benzole, and especially the latter, render the insects very rigid, so that there may be some difficulty in setting' them after. The fiunes of burning sulphur have also been employed, but I denounce this at once as troublesome and inconvenient, and because it so often results in damaged specimens. The' laurel bottle or' laurel box' has many decided advantages. Some young laurel leaves are well beaten with a hammer, wrapped up and tied in a piece of calico or strong muslin, and then pressed firmly into the bottom of a wide-mouthed bottle or a cylindrical tin box. It should be pressed in so firmly that there is no chance of its falling out of its place; and should fit close round the sides of the bottle to prevent insects from being jammed between it and the glass. I have made a very useful laurel box as follows: Procure two cylindrical tin boxes of exactly the same size-four or five inches S64--TE high and about two in width answers admirably. L.UREL Box. One is required only for its lid. Knock or cut out the bottom of one box. Make a false bottom of a, space for illn- sects; b, perfo- perforated wood, and fix it in this, about one-third rtd pnisirt itin from one end, and then put the two lids, one on leave,. each end. The smaller division is to contain the. bruised laurel leaves, and the larger is for the insects. The laurel is very quick in its action, but should always be used fresh. It will keep the insects in a moist or relaxed con- INSECTS AND INSECT HUNTING edition, so that they are easily set, either on the same day or a few days after the capture. The box just described may be used for the other stupefying agents as well as the laurel. Thus the smaller division may contain some cyanide wrapped up in blotting-paper or linen rag, or it may be filled loosely with cotton-wool or any absorbent to which either of the liquid agents may be applied. In fact, this is altogether a very convenient arrangement, for the charge can be renewed at any time, even when the insects are in the other division, and with- out disturbing them much. It must be remembered that the liquid poisons--chloroform, benzole, and ammonia-are volatile ; and, as a consequence, some is lost in the form of vapour each time the box is opened. Hence it is advisable, when using either of these, to take a small bottle of it in the waistcoat pocket for recharging. Care must always be taken to leave the insects in the killing bottle or box until quite dead. We cannot easily tell when that is, for they are stupefied and rendered quite motionless before death takes place ; and if removed too soon they will often revive. Butterflies are so delicate that it is not safe to allow them to remain in the killing box very long, to be trampled on and turned over by their new arrivals; nor is it well to leave them loose in boxes of any kind, for their wings are easily damaged if they are shaken about. They should be pinned as soon as dead. For this purpose the collector will require a 'collecting box and some entomological pins of various sizes. The former should be as large as can be conveniently carried in the pocket. It should be either oval in form, or oblong with rounded corners. As most of the insects, and possibly all of them, will be taken home in this, it will be advisable to have the box so con- structed that they cannot become dry in it. For this reason it should be of tin or zinc, the cover fitting closely, but opening easily by a hinge or hinges. The .box should be so deep as to allow the butterflies to be pinned to both the top and the bottom, which should be lined with cork. Just before starting on the collecting expedition the cork should be saturated with warm water, or a piece of damp sponge pinned firmly in one end, as a further precaution against rigidity. The pins used by entomologists are very fine, with small heads. They are sold at the 'naturalists' shops,' and may always be obtained through the post. A great deal depends on the choice of the day for a butterfly ANIMAL L1FE hunt. A bright warm day is essential; and it should be known that these insects will never expose themselves to an east or north- east wind. The best time of day for actual work is between the hours of eleven and four; and the best localities are flowery meadows -especially the borders, lanes, chalky districts, flowery railway- banks exposed to the full sun, clover fields, borders of woods, and flowery wastes. It must be observed that many butterflies are very 'local.' Hence if we are in search of any of these, it is necessary to make ourselves acquainted with their haunts. It would not be ad- visable to dwell on this subject now, but some of the chief pecu- liarities of many species will be mentioned presently. Having at last reached our hunting-ground, how are we to pro- ceed ? We all remember the time when a butterfly, white or purple it mattered not, was a certain stimulus resulting in the violent action of the muscles of every limb. It was the signal for a chase, and the contest between ourselves and the insect was always one of speed and endurance. And then, if successful in bringing down the winged creature with the cap, or, it may be, the coat, with what pride did we pin the insect to adorn the very weapon by which it was laid low But now our captives are to form a permanent and useful collection. They must necessarily be caught without injury to their appearance, handled with the greatest of care, and killed in the most humane manner possible. We therefore relin- quish the cap for the net; and learning by experience that the but- terfly on the wing is sometimes more than a match for our legs, we resort to stratagem. As a rule it is not advisable to start off at full speed immediately on seeing the insect, but follow it up gently, keeping some distance behind, giving the creature every opportunity of alighting on its favourite plant or flower, and then a few cautious steps and a sharp stroke of the net will generally settle the business. Sometimes, however, a butterfly shows at once by its almost straight and unhesitating movement to be intent on a long flight. In such a case, should you desire it, you must make up your mind for a good run, with one eye on the insect, and the other on the look-out for ditches, mole-hills, and furze clusters. The insect is sure to flutter a great deal in the net, and no attempt should ever be made to handle it until it is quiet. If a killing bottle is to be used, this might be passed at once into the net by the left hand, and the bottle covered quickly by the right as soon as the insect is secured. If this plan is adopted, we soon find a number of captures in the bottle ; and, as we are still actively on INSECTS AND INSECT HUNTING the chase for more, we are liable to injure these by causing them to rub together as we run. To avoid any damage in this way the butterflies should be pinned in the collecting box as soon as we are satisfied that they are quite dead. Some collectors dispense with the killing bottle for butterflies altogether. They wait till the insect can be secured in the net, with its wings closed over its body, and, gently pressing the folds of the net against it from the outside, kill it instantly by nipping the thorax between the finger and thumb. Of course this must be done with the greatest of care, or the insect may be so damaged as to be perfectly useless. One objection to this mode of procedure is that the insect may only be temporarily quieted; so that, when we open the collecting box for a future speci- men, we are horrified at the sight of our pinned butterfly struggling to escape. Setting and arranging the Butterflies Our butterflies must now be 'set' for the cabinet. This need not be done at once-in fact, it may be postponed for many days or weeks-but it is always advisable to set them as soon as possible. If they are in a metal collecting box, their limbs will remain soft and pliable for some days ; but they should not be kept in a moist con- dition for a great length of time, or you will find them completely covered with a forest of mildew. It is of no use attempting to set an insect after its limbs have become dry and brittle, for under these circumstances the slightest pressure will cause a part to snap off. The insect must first be 'relaxed.' To do this it is simply necessary to pin it for a day or two in a metal box containing a damp sponge or moistened blotting paper, or to keep it for a corresponding time under a tumbler or other vessel with some means for keeping the inclosed air moist. A very simple plan is to fix the pinned insect to a cork, float it on a little water in a saucer, and then cover it with an inverted tumbler. The dealers sell relaxing boxes' for bringing about the same result. These are zinc boxes lined with cork and covered with a well-fitting lid. The cork is kept in position by means of small projecting pieces of metal in preference to any kind of glue or cement, as the latter would not stand the perennial dampness. The cork may be moistened with a little water, or a piece of damp sponge may be pinned inside, and the box is then ready for the F ANIMAL LIFE insects. The specimens brought home in a wood collecting box are often so dry that they cannot be set even on the same day; but if a metal box be used there will be no need for the relaxer, for they will keep in a good pliable condition for several days. If an insect, when set, does not give satisfaction, it may at any future time be relaxed and reset; and collectors often find it con- venient, when away from home for some time, to keep all their captures in the collecting boxes till they return, and then set them at their leisure, relaxing them in batches as required. This avoids the necessity of taking away the setting boards' and store boxes. Space, too, is a matter of great consideration, and insects usually pack away in a much smaller compass before than after setting. When engaged in setting our specimens we must always avoid the direct use of the fingers. The best way to get the various parts into their proper positions is by the use of a needle mounted in a small wood handle. A few of these setting needles should always be kept handy. They are easily made by cutting little pieces of twigs, and then pushing the heads of ordinary sewing-needles into them. They may be of different sizes to suit the various degrees of delicacy required in the manipulation. 'Setting boards' are now required. These are usually con- structed as shown in section in fig. 65. A piece of soft deal, free k'-2. *- ', *4 u FIG. 65.-SECTIONS OF THREE HINDS OF SETTING BOARDS. fiom knots, and about a quarter or an eighth of an inch thick, is cut into strips about eight or ten inches long, and varying in width from one and a half to five inches. These slips are covered with cork, glued on, and then grooved down the centre to receive the bodies of the insects. Lastly, the surface of the cork on which the wings are to be laid is covered with clean white paper. Such boards may be obtained at the dealers' ; but, if expense is a con- sideration, seeing that several will be required, they may be made in a very economical manner. The cork bed may consist entirely of sliced wine-corks, cut clean with a sharp knife, and then glued to the wood quite close together. INSECTS AND INSECT HUNTING Or cork may be dispensed with altogether if good wood, uniformly soft, is procured. In this case it is simply necessary to cut a groove with a gouge, and bevel off the edges with a plane, if neces- sary; or, I might say, if it suits the fancy of the collector. There is a great difference of opinion with regard to this. Some prefer a rounded board, some a plain bevel on each side, and others a perfectly flat surface. For my part I reject the round board, since I have never yet seen a live butterfly with wings bent into a curve. Whatever form be adopted, all the boards should be of the same pattern, so that there may be a degree of uniformity in the cabinet. The setting is done as follows: First see that the pin is passed centrally through the thorax. If not satisfactory, it should be re- moved and reinserted, passing it through till the point is pro- jecting quite one-eighth of an inch on the under side. Now fix the pin in the centre of the groove of the setting-board per- pendicularly. Spread out the wings with a setting needle, being careful not to touch the upper surfaces, and then secure them by means of little strips of rather stiff paper as shown in the accompanying cuts. Some of FIo. 66.-A BUTTEEFLY ON THE the butterflies, at least one of SETTING BOAnD. each species, should be set 6n their backs, so as to show the under surfaces of the wings and other distinguishing characters of the under surface of the body as they lie in the cabinet. As a rule four of each kind is sufficient for all purposes: two of the male and two of the female, one of each exhibiting the upper, and one the lower, surface. In some cases, however, the species is so variable that it will be interesting to introduce a few others simply to illustrate the varieties. And now we come to one of the chief difficulties which the young collector has to experience. Where shall we keep all our specimens ? The boy who is clever with his tools does not hesitate long over this matter, but sets to work at his cabinet or his boxes ; and I can personally declare what a pleasure is to be derived from putting F2 |
