The description of the principles aud mechanism of the Serrell auto-

It will be found useful in explaining the advantages which that deli-
cate and remarkable invention has over the ordinary reel as a labor-
saver, though no amount of description will impress the fact on the
mind so forcibly as a few moments' observation of the reel at work.

species that attack and destroy it in different ways, and the injury and
loss is very great.
Necessarily I have given considerable time and study to unraveling
the life histories of some of the more important ones, giving them that
prominence in my report that their importance to the grower seem to
warrant.
THE CABBAGE PLUSIA.
(Plusia brafssie Riley.)
This is one of the most serious and destructive of cabbage insects.
Prof. C. V. Riley first described it in his Second Missouri Report, 1870,
page 110.
Distribution.-TVhile, undoubtedly, originally indigenous to theSouth
ern States, it is now very generally distributed over most of the Eastern
and Western States. In U. S. Agricultural Report for 1883, Professor
Riley states that he has received it from Mississippi, Georgia, Florida,
the Carolinas, Alabama, Texas, New Jersey, M issouri, Kansas, Nebraska,
Virginia and 3Iaryland.
Food Plants.-The food plants of the larva-, as given in same report,
are Cabbage, Kale, Turnip, Tomato, lignonette (Reseda), Dandelion
(Taraxacuim), Dock (Rumex), Crepis, Chenopodium, Clover, Seecio scan-
dens, Lettuce, and Celery. Professor Riley also says: "~' We have
also found it in Florida feeding upon the Japanl Quince (Cydoniajaplon-
ica), and it has been found in Washingtol upon same plant."
Life History.-The life history of this insect is treated in the Annual
Report of the D)epartment for 1883, Ipp. 119-122, and it is figured at
Plate I, figs. 2 and 2e, and Plate XI, figs. 2, a, b, c. The different stages
are described in Professor Riley's Second Missouri Entomological Re-
port, pp. 111-112.
XSumber of Broods.-Professor Lintner, State Eutomologist of -New
York, in treating of this species in his second report, page 92, says:
"In its more northern extension there are two annual broods,for, from
larv;e taken in August, after about two weeks of pupation, Dr. Thomas
has had the moths emerge on the 1st of September, which deposited
their eggs for a second brood in October. In the Southern States there
are probably four broods, for Mr. Grote took examples of the moths in
Alalam;ia during the last of February."
IlHere in Florida there are certainly not less than six broods, for I have
take n the moths every month but the winter months, November, De-
cenlmber, and January.
Its Injllrics.-Not a cabbage patch visited by me this spring and sum-
ner hit was more or less damaged by the attacks of this terrible cab-
bage pest, and the injury it does and the loss sustained by the trucker
is in Inense.
The very young begin by eating the tieshy portion of the leaves; as




they grow ill size a ld "At Ie tig I II1 t e g II; irIIre-gula I hoeIsII1 1 .- thIIrol)(g-I tI It

THE CABBAGE PLUTELLA.
(Plutella cruciferarunt Zeller.)
Second only in im ortance to the Cabbage Plusia is another cabbage
worm, the "1 Cabbage Plutella," the larva of a small moth, aiidl which
may easily be confounded with the very young larva of the Cabbage
Plusi a.
This insect was treated at some length in Professor 4ile Us annual
Report as Entomologist to the Department for 1883, and it will therefore
be unnecessary to go into detail here. I may state, however, that while
at the North there are probably but two annual generations, there are
at least four here in Florida. The larvT, are quite plentiful on cabbage
from the last of February to July, and again in the fall. The damage
(lone is very similar to that of the Plusia and is almost as great, al-
though it seldom attacks other than the outef leaves.
I have bred a parasite, additional to those mentioned by Professor
Riley ,which agrees with the description of Cresson's Limneria obseura.
THE CABBAGE APHIS.
(Aphis brassiew Liun.)
The Cabbage Aphis (Aphis brassicce' first described by Linnats, in
his "Systema Naturxr," is quite widely spread throughout this country
and Europe. It was undoubtedly imported into this country at a very
early day, for Dr. Fitch shows, by reference to the Transactions of the
-New York State Agricultural Society for 1791, that it was already
known as a cabbage pest at that early date, and at this day it has
spread to most parts of the world where the cabbage is cultivated.
,thod Plants-It is found on the Turnip, Raddish, Field-cress (Isatis
tinto ari), Shepherd's-purse ((Capsella b ursa-pastoris), Charloch (Brassief
arreiisis), Cabbage, and other cruciferous plants.
Here I found it on Cabbage, Turniip, and Raddsh.
ITS LIFE IIISTOnl.-Thie Young.-These are oval, about .01 inch in
length, and of a greenish-yellow color, without the mealy coating of the
older ones.
Iluckton, the British authority on the Aphidithe, thus describes the
flifferenmt forms:
jih plcrs Viriparous Fmoia .- dy lolng, oval; plentifully covered wkith a m hitish
Imiealy coat, both on the upper nnd undsi. When this is removed by a drop of
spirits of wine the body below is g iiicv-gren, ith uight black spots ranged down

TInE CABBAGiE APHIS SYRPHUS FLY-A llogr-apta oblique Say.-The
larva or miggot of this fly has been taken feeding oil the "Cabbage
Apbis," and below I give description of its various preparatory stages:
Te E'gg.-Pearly white, long oval; .03 inch in length, deposited on the leaves
among the Aphids.
The May got.-t is difficult to distinguish this from many other Syrphid larva .
The full grown larva measures .25 inch in length, cylindrical, tapering anteriorly to
point; it is perfectly smooth, a translucent green, and the viscera are plainly discerni-
ble, variously shaded, dark greei, yellowish or brownish ; the jaws are black; the air
vessels, which are visible on either side through the body walls, become contiguous on
last segment, where they are connected externally with two small warty spiracles.
The luparhi .-Tbe puparium into which the maggot transformis resembles a Cone,
,with the side attached to the leaf, lattened and held in place by a viscid substance
secreted by the larva ; its anterior end broad and -well rounded, gradually Dar-
rowing posteriorly; at the end are still to be seen the two warty tubercles. Color
yellow-brown, with occasionally darker shadings.

hardly a perfect ear ton be found. At I imnes it is also founntl at lit,




base of the tassel, feeding on the accumulated saccarhine juice, found
there, just before the tassel emerges from its sheath.
The worms will not only gnaw irregular burrows and feed on corn
while in the milk, but the mature larve are known at times to continue
feeding on mature hard corn.
I have taken on corn two hemiptera or bugs which probably prey on
the worm, although not detected ill the act-the Wheel Bug (Prionidus
cristatus L.) and E-uschistus servus Say. From the egg I bred Tricho-
gramma pretiosa Riley, already noticed; but no other parasite has been
bred from it by me.
THE CORN MINING FLY.
(Diastata sp?)
A mining fly larva is quite frequently met with, making long irregular
mines on corn leaves, and while I have not been able to rear the perfect
fly, yet I am satisfied it is the same species mentioned by Prof. Com-
stock, in U. S. Agricultural Report for 1880, page 245, as Diastata sp.
Several specimens of a parasite, agreeing tolerably well with Mr.
Howard's Entedon diastatw, reared from it at the North, were also bred
from it here.
MISCELLANEOUS CORN INSECTS.
A Hemipteron (Oebalus pugnax Fabr.) was found in considerable nunm-
bers feeding on corn pollen, along with a Capsid and several flies. A
fly (Ortalis sp.) is common on the stalk, but was not observed to do any
injury. A common beetle (Allorhina nitida Linn.) was taken, with head
immersed in the ear, feeding on corn while in the milk.
OTHER INSECTS INJURING CORN IN FLORIDA.
The following insects also injure corn here: The Corn-stalk Borer
(Diatrwa saccharalis Fabr.); the Corn Bill-bug (Sphenophorus robustus
Horn.), and the Angoumois moth (Gelechis cerealella) and several Cut
Worms. From the tassels I have taken the larve of Yola sorghiella
Riley, and in the crib the Corn Weevil (Calandra gralnaria).
INSECTS AFFECTING THIIE TOMATO.
The cultivation of the Tomato for Northern markets is a rapidly grow.
ing industry in Florida, particularly in the southern portions of our
State; and thousands of boxes are now forwarded by our growers to
Northern commission men every season.
It behooves us, therefore, to keep a watchful eye on the insect depre-
dators of this fruit, for we may naturally expect, with the extension fi
any horticultural industry, a corresponding increase of insect pests.
Fortunately, no serious damage done this plant by insects has been
reported this season, and, while I have been unable to visit West and

I submit a description of the Teleas, which is apparently new:
TIIE SI'IIxx EGG TiLEAS-Telea8 bpthingqi n. sp.-Length,.04 inch. Black, smooth,
and polished. iead large, much broader than thorax; antenna 12-jointed, dark
brown, sparsely pubescent, the scape barely reaching to the head ; pediel much
stouter and larger than first funicle joint, which is small; other joints slightly in-
crease in size to club, which enlarges and widens considerably, and comprises five
joints; the antennae in male are more flagellate. The thorax is ovate, smooth, con-
vex, and sparsely covered with microscopical pubescence.
Under a very high power the head and thorax show a microscopical reticulated
scratched surface.
No parapsidal grooves; the scutellum is separated by a deep groove at bass and has
some wrinkled ridges; metathorax rugose. The abdomen is very flat ovate, and
somewhat carinate laterally; on first segment there are three deep transverse, puuc-
tate grooves, and the second segment occupies most of the upper surface; surround-
ing the tip are a few hairs.
Legs clavate; femora and coxw black or very dark brown; tibine brown, with tips;
tarsi and trochanters yellowish or tawny; wings hyaline, hairy, and with a distinct,
rather long, stigmal vein.
Described from numerous specimens bred in July.
Remedy.-For destroying this worm no better method need be wanted
than hand-picking.
The worms are large and conspicuous, easily seen, and no difficulty
will attend their destruction. The best time for searching for them is
in the early morning and evening; during the middle of the day the
majority oft them will be found hidden under trash and in the ground
at the foot of the vine.
THE TOIATO-STALK BORER.
(Gortbna nitela Guen.)
This insect is comparatively rare in Florida, although I have noticed
it several times the present season. It has been so often treated in the
reports and in popular articles as to need no extended notice here.
THE TOMATO APHIS.
(Megoura solani Thomas.)
In some cases brought under my observation this year, this Aphid
did considerable damage to tomato vines, particularly in the early
spring.
Distribution.-It is pretty generally distributed throughout the
United States, although it has not been reported, that I am aware of,
west of the Rocky Mountains.
Its Natural History.-Prof. Cyrus Thomas described the species in the
Eighth Illinois Report as follows:
Ifinged IFenole.-Antenow 7-jointed, a little longer than the body; first and second
joints short; third and seventh longest, nearly equal ; fourth a little shorter than the
third; the lifth not quite as long as the fourth; sixth about half or less than half
the length of the lifth: tublercles prominent. Honey tubes extending beyond the
abdonen, excessively enlarged in the middle, and expanding at the tip in trumpe t

INSECTS AFFECTING THE EGG PLANT.
The .egg lant is comparatively but little cultivated in Florida, and
no serious injury is done it by insect pests.
The "1 Tomato Worms," Sphinx carolina and Sphinx 5-naculata are
both found on it eating the leaves; also a Tortrieid (I d a Tineid.
A Membracid (Acutalis cailva Say) is found on the stalk, a Blister
Beetle (Lpicauta cinerea irst.) in blossoms, and occasionally eating the
leaves; at times a small black jumping bug (Halticus bractatus Say) is
-very plentiful on both stalk and leaves, as well as Stictocephala in-
,ermis Fabr., and on the under surface of the leaves an Aphis,
THE EGG PLANT APHIS.
(Siphonophora cucurbitm Middleton.)
Distribution.-This species was first detected on Squash vines at
Carbondale, Illinois, May, 187S, by Miss Nettie Middleton, and deseribe~d
in Eighth Report Illinois Insects, page 67, and lknow of no other ref-
erence to it. The specimens found here on Egg Plants agree perfectly
with her description, and it is probably extensively distributed over the
Easter i United States on various plants belonging to the Cucurbi-
tacew.
I quote her original description:
Tinged Specinenics.-Large aud green. Antennti very long, reaching to or beyond
the tip of the tail; third joint a little longer than the fourth; fourth about thesamte
length or very slightly longer than fifth; sixth not more than one-fourth or one-third
the length of the fifth; seventh longest; wings transparent; veins slender; the first
fork makes a very acute angle with the third vein; second fork rather nearer the
third vein than the apex; fourth veia curves sharply and approaiches somewhat
closely iu its middle to the first fork; stigma elongate and narrow ; honey tubes
long, slender, and cylindrical, extending beyond the tip of the abdomzen, but not to
the tip of the tail, about one-fifth the length of the body; tail long, subeonical, more
than half the length of the honey tubes (in the wingless speciimens). The fori of the
body in both the winged and wingless specimens is elogate andl fusiforul, the latter
being slighttly broader than the former. Leugth of body .10 inc, to tip of wing .18
inch,l and ,otie appear to even exceed this size; body green; ead paler, more or less
yellowish; thorax pale brownih or fawn colored or tinged with this color; abdomen
green, with a barker green median line; first awl second joints of the atiinnii pale,
third dark, seventh light, shades of light and (lark more or less alerrnating:; honey
tubes green at base, changing to fusepus at the tip; tail greenish; eyes brown;
sti-ma pale.
Witylesi Speeiiieti.-Green, with few markings: Body slightly broader thau winged
specitnens, antd eiongate ovate; the abdomen tapering posteriorly to the elonai-tcid
tail, which is elongate conical, its length iwiore thn half and almost efalw to that ,'i
the hioney tubes. The honey tubes are long, sottewhat roblms and cylindrical; they
extend beyond the tip of the abdomen, although the posterior tapering segments are
much drawn out, but not to the tip of the tail. In most of the speciniIs examined
under a strong magnifying power they appear slightly andmi uiitely wrinled trails-
versely, or what may perhaps better describe the appearaue 3 pustuiate or scaly. The

ITs LIFE IHISTORY.--The Egy.-Unknown.
T1'e Larra.-This in shape ant size very much resembles the Cabbage Worm (Plusia
brassico,.) and, like it, when disturbed draws itself up and has the appearance of a geo-
Imetrid larva. When full grown it measures one and one-tenth of an inch in length.
Pale green, with a wavy, yellow stigma line and a supra-stigma creamy white line
and two pale dorsal lines, 8 transverse black warty dots on segments with two more
on dorsum back of these, from all of which issue pale hairs ; on either side of the
dorsal black warty tubercles is an irregular yellowish line, and an indistinct yel-
lowish oblique line extending from the outer line obliquely between the first pair of
tubercles and last pair to the dorsal lines. The six true legs are pale, glassy, and
there are prolegs on ninth, tenth, and anal segments. Head green,'With sutural edges
dark anda few hairs at sides.
The l' a.--Lcngth, .42 inch; greatest width, .15; wing cases, .21 inch; pale yel-
low brown, the fifth segment rather strongly constricted anteriorly and widest; the
edges of all the segments anteriorly dark brown.
The Moth.-Wing expanse from one inch and ten-hundredths to one inch and fifteen-
hundredths. The fore wings are grayish brown, with a few short, indistinct, wavy,
lighter grayish lines interspersed; transversely across the fore wing near the outer
margin is a light gray or slightly yellowish band.
The hind wings are uniformly gray, fringed with short cilia; beneath, silvery gray
with numerous brownish gray scales at anterior margin and on fore wing.
Its Injuries.-The worm feeds on the leaves and the bean pods, some-
times stripping the vine bare.
OTHER BEAN INSECTS.
A Katydid (Phylloptera oblongifolia Dels.), a Buttertly larva (Euda-
mus proteus Linn.), and a Tineid are also found damaging this crop.
INSECTS AFFECTING THE SQUASH.
In Florida there are many insects found feeding on this plant; the
Cucumber Flea-beetle (Crepidodera cucumeris Harris), the 12-spotted Dia-
brotica (Diabrotica 12-punctata Oliv.), ajumping bug (Ialticus bractatus
Say), the False Chinch (Triphleps insidiosus Say), a Mining Fly (Oscinis),
and an Aphis (Aphis cucurbitc Buckton) are common on the leaves and
stems, but have not been observed to do much injury. The life histories
of and observations concerning the more injurious are given below.
THE SQUASIHI BUG.
(Anasa tristis DeGeer).
When this bug exists in quantities probably there is no more inju-
rious insect known to squash and pumpkin vines. The mature bug
hibernates in the winter under debris, old vines, dry grass, boards, &e.,
and from early spring to late fall there is a continual succession of
broods.
I have taken some specimens in mid-winter, on warm days, in old
fields and on fences.
Distributioln.--It is found generally throughout the United States and

The Reduvius Egg Eupelmid-Eupelmus redurii Howard.-Seven
specimens of what I have identified as this species were bred from Anasa
eggs in July.
For a description of the species see Canadian Entomologist, Vol. XIIT,
page 207.
TIIE SQUASH BORER.
(Eudioptis nitidalis Cramer.)
The worm so commonly found with us boring into squashes, at the
North goes under the name of Pickle Worm." There it is found eat-
ing the leaves and boring into the fleshy portions of the Cucumber.
Distribution.-It is found in the West Indies, throughout the United
States, and in Canada.
Food Plants.-As a borer it is found in Squash, Cucumbers, and Mel-
ons, but it will also feed on the leaves of all of .these vines. The moth
is very common and it must have other food plants; Guenbe mentions
a species of Potato as its food plant.
Its Injuries -The worms bore cylindrical holes into the Squash, and
feed on the fleshy pulp, causing it to rot and decay.
P'arasites.--From one of the pupe I bred a Chalcid fly, Chalcis ovata,
S.iy, but no other parasites are known to infest it.
Reinedy.-Professor Riley, Second Missouri Entomological Report, p.
70, suggests overhauling the vines early in the summer, and destroying
the first worms that appear, either by feeding the infested fruit to hogs or
cattle, or by killing the worms on the spot."
THE SQUASH VINE BORER.
(Mlelittia ceto Westw.).
This well known insect, unlike Eudioptis nitidalis, does not bore into
the Squash or fruit, but into the stem of the vine, often killing it.
I have taken two or three borers at a time from a single stem, and in
confinement they proved to be cannibalistic-feeding upon one an-
other-as was exemplified with some 1 attempted to rear this summer.
No borers were observed in the vine until July.
D)istribution.-Found generally throughout the United States.
Food Plants.-Its attacks are almost strictly confined to the Squash,
although it has been reported to bore at times into Pumpkin vines.
ITS L IFE IIsTonY.-The egg.-The egg is oval and of a dull red.
The Larra.-Full grown larve measure from one inch to one inch and a fourth.
Somewhat depressed, fleshy, soft, tapering at each extremity; segments ten in num-
ber, very distinct, the incisions being deep; the eleventh or last segment minute, and
hardly distinct from the tenth. Iead retractile, small, brown, paler on the front, and
with the usual V-like mark on it. First segment or collar with two oblique brown
marks on the top, converging behind. A d(lark line, occasioned by the dorsal vessel

the Farmers' Review for September 2, 1880, says: There has been
great complaint among our gardeners this season in reference to a
plant-louse that is doing much injury to the nutmeg and muskmelon
vines, and also to the cucumber vines. In some instances they have
almost entirely destroyed"the entire fields of vines."
ITS NATURAL HISTORY.-VOY Young.-Length, .02 inch; greenish yellow; eyes,
brown ; tips of honey tubes brown; legs pale.
tingless Female.-Length, .04 inch; yellow; eyes dark brown; honey tubes
slightly conical, black; cauda distinct, dark green : legs pale; extreme tips of tibim
and tarsi black.
Winged Eemales.-Length, .05 inch, ovate; head and thorax shining black, some-
times with the prothoracic segment green or yellowish ; the auteunaue are dark and do
not reach the honey tubes; abdomen dark-greenish yellow, spotted along sides;
honey tubes black, thickest at base, gradually tapering to tip; cauda distinct, green-
ish yellow or dark green ; wings hyaline, with stigma and veins pale yellowish ; legs
pale, with tarsi and extreme tips of tibite and femora black.
Its Ijluries.-The viviparous female breeds very rapidly and is soon
surrounded by young in various stages of growth. In a brief time these
reach maturity, wander off to new leaves and shoots,and begin colonies
of their own. When these lice become too numerous they exhaust the
vitality of the vine, distort the leaves and cause them to curl up and
wither. The growing terminal shoots are also crowded with them, and
then the vine can make no headway ; it is fruitless and dies.
It is one of the most destructive plant-lice. To illustrate its destruc-
tiveness I cannot do better than quote from an article I wrote in Florida
Dispatch, July 27, 1882, after investigating its injuries in Georgia:
Some figures here in regard to the damage done by the Watermelon Aphis" will
not be amiss, and will show our planters tbe necessity for prompt and united efforts
in its destruction.
In Georgia the estimated yield of the watermelon crop this year (1882) for ship-
ment was 900 car-loads, or 900,000 melons. Many at the beginning of the season
bring $40 and $50 per hundred. However, to keep within a fair valuation and rather
below the true amount, we will say they bring $25 per hundred, which equals, in
round numbers, for the crop $225,000. Now, what has been the yield? The ship-
ments are nearly over, and they have not yet reached 600 car-loads, a falling off of
33- per cent., or a total loss of $75,000, due mainly to the ravages of an insect!
The above statistics of loss are founded upon data of the estimate yield for but
three counties, principally Thomas, Brooks, and Lowndes, in Georgia. In Florida
the crop has from the same cause met with a loss still greater, and we are considera-
bly below the estimate when we say the total loss to the planters of the two States
is not less than $150,000.
Natural Enemies and Parasites.-These have not been specially
studied, but the enemies and parasites will be found to be similar to
those of the I Cabbage Aphis "--flies belonging to the family Syrphi-
die, the Lace-wings (Chrysopidwt), Chalcid flies (Chalcidide,) and Lady-
birds (Coccinellidw.)
Remedies.-An important help in their destruction, and to which the
planters' especial attention is requested, and which is equally applicable
to other crops, is the following, which, if universally carried out, would

most unanimously agreed that these adult Authootyia were the depredators, it really
seemed that the term Bntlo-gnat here ight, like the Tent-worm and the Weevil in
other localities, include a variety of insects.
Wishing to make the best possible use of time, I utilized the bad weather also by
visiting our correspondent, Mr. Robert E. Craig, at Luna Landing, Chicot County,
Arkansas, spending a few days there, and at Greenville, Miss. returning to Somer-
set March H.
tThe th and 10th being pleasaut, the Athonmyia again appeared, but, although
very demonstrative, none were observed to alight upou the tens at work. This fact
led to the impression that my information had been incorrect, and that I wason the
wrong track. This proved true, for during my entire stay I never saw one of these
Antlhionyia alight on stock.
On the 11th word cate that mules were being harassed by gnats on a plantation
six miles to the northwest, and, on the following day, I rode out to that locality and
found the true gnat in considerable numbers.
Four days were now spent in a fruitless search for the adolescent stages in the
bayous and ditches adjacent to the locality where thile adults had now appeared, and
as many minore were lost on account of had weather.
During this time, and up to noon of the 20th, no adult gnats had appeared on the
Somerset plantation. A strong northwest wind bad, however, set in during the mornt-
ing, and by evening the gnats were quite abundant. The next day (Sunday) the
wind blew still stronger from the same quarter, and Monday morning, the 22(1, found
them abundant enough to cause some considerable uneasiness among the teams at
work.
Fully satisfied now that these gnats did not breed in the vicinity of Somerset, I
started out on horseback, and after riding for about eight miles toward the northwest
reached a small stream known as Mill Bayou. Following this down stream, through
the woods, the current soon became quite rapid, the banks being more or less grown
up with brush and bushes, to below the water's edge. The gnats, too, whose num-
hers had been continually increasing, now became numerous enough to worry miy
horse considerably.
Finding that little could be accomplished in the way of inspecting the stream with-
out a boat, and it being too late in the day to procure one, I returned to Somerset.
On the next day, the 23d, procuring a dugout, a thorough examination was made,
not only of Mill Bayou, but of two others, tributaries to it, one of which had no per_
ceptible current, the result being that where there was no current no larv of gnats
could be foufid. As the current became sluggish a few were observed, the number in-
creasing in proportion to its rapidity, reaching the maximum in numbers in the
swiftest current of Mill Bayou; always provided, howeve r, there was sufficient mate-
rial to which to attach themselves. Thus, the larwe would occur abundantly on one
side of the stream, where a bend caused it to run very swiftly, while on the opposite
side, in comparatively still water, few could be found.
Upon inquiry and personal investigation, this bayou was found to be receiving
water from the Mississippi River through Lake Palmyra and Bayou Vidal, and also
that its water rose and fell with that of the river itself, until the height of the latter
fell below 25 feet onil the gauge at Vicksburg.
It now seemed quite important to learn to what extent, if any, the other inland
bayous were influenced in this manner, and, as the country is of difficult acceSs, I
thought best to visit our correspondent, Judge A. A. Gnuby, of M31sroo, Louisiana,
whose circuit I knew comlprised the e:ltire in fasted territory of the northwestern por-
tion of the State, and whom, I learned, was then at home on a short vacation.
Leaving Somerset on the 25th, and returning again on the 31st, I was, by this
journey, enabled not only to obtain much valuable information from Judge Gunby,
but also to examine the Washita River, and also, but very superficially, on account
of recent heavy rains, the country between it and the Mississippi River.

The deer were driven from the woods, and frequently tok -
their tormenters in the smokes, built by planters for the 1)
their cattle ; when in their ago 'ny they would allow people
gnats from their bodies, and would even lay down in theta
bers, or hot ashes, in their frantic endeavors to seek relief.
In 1884 the gnats again appeared in great numbers, and v
destructive as in 1882. Throughout Franklin Parish, LouiSia
week from their first appearance, they bad caused the de
bead of stock. And for the first time in the history of th,

of Vicksburg, Miss.
-No general outbreak took place in 1885, yet they appeare
and Franklin Parishes insufficient numbers to kill quite a

During the present season, although the gnats appeared

Yazoo River in Mississippi ', no fatality to stock had been

plantations on account of gnats.
Generally speaking, the Southern Buffalo-gnat may be s,-
the low, flat, wooded country adjacent to the Mississippi Ri
tributaries, from the mouth of the Red River in Louisiana
at least as Southern M issouri.
I have found nothing to indicate that these gnats origino
streams, or even in small ones in hilly localities, although

to spend the night among grass and like herbage. They are exceedingly
active, and no sooner have they gained a foothold on an animal than
they are busy at their bloody work, selecting the breast, flanks, ears,
nose, or wherever the skin is the most easily punctured.
Very inconspicuous in their flight, makinglittle noise, seldom arising
more than a few feet from the ground, they often bite mules working in
the fields, sufficiently to cause death before their presence in considera-
ble numbers has been discovered. This will, perhaps, account for the
prevailing notion that the bite of these gnats first appearing is the
most poisonous, for inclement weather and adverse winds may cause
them to appear, for the first, at any time during the breeding season,
in localities where they do not actually originate, and, as willbe shown
farther on, the same wind that holds them back from one locality may
convey them to another. It would appear as rather more probable,
however, that the poison introduced into the animals' system by the
bites of the first gnats, unless sufficient to prove fttal, may to some ex-
tent serve as an antidote for that introduced by those appearing later;
and should this poison remain in the system with considerable stability,
the fact would alsoaccount for acclimated stock being less susceptible to
poison from the bites of these gnats than those unacclimated. Except
in the case of great numbers, death does not necessarily follow the bite
of these gnats, and even then it is not suddenly fatal. Mules that at
night do not appear to be seriously injured will often be found dead
next morning.
Stock, and mules especially, that have been fatally bitten by gnats
are affected in much the same manner as with colic, and, in fact, many
think the bites bring on that disease. But Dr. Warren King, of
Vicksburg, who has made a large number of post meort(m examina-
tions, states that he has never been able to obtain any acts which would
justify such a conclusion.
Dr. King opines that the effects of these bites from gnats are on
animals much the same as that of the rattlesnake on the human sys-
tem; and this seems to be the generally accepted opinion among the
more intelligent planters.
In regard to artificial methods of counteracting the poison of gnats,
there is of course no end, apropos to which, one planter remarks that if
the gnats failed to kill the mule the remedies used certainly would.
Be this as it may, I could learn of no measures that had been generally
tested and proved effective, and no opportunity was offered me to make
any experiments in that direction.
Dr. King recommends rubbing the affected animal thoroughly with
water of ammonia, and administering internally a mixture of 40 to 50
grains of carbonate of ammonia to one pint of whisky, repeating the
dose evo y three or four hours until relieved. The doctor claims to
have never lost an animal under this treatment, although they were
sometimes apparently beyond recovery. This measure I do not think

discouraging, there is yet some hope of relief, and that, too, from quar-
ters little expected, by myself at least, when these investigations began.
But, in order to fuiilly understand the matter, it will be necessary to
bring together, not only chronological data relating to the insect in
question, but to the height of water in the large streams during the past
thirty-five or forty years. Also, we must understand something of the
nature of the country which these gnats inhabit, as well as the elements
necessary to their production. And not only must these facts be
weighed independently, but very carefully with relation to each other,
for it is more than probable that it is through a combination of circum-
st;iuces that the pest holds its sway.
A very noticeable feature connected with the occurrence of the Buf-
falo-gnat is, that below the Arkansas River there is no record of any
fatality to stock, attributable to gnats, previous to the outbreak of the
war, even in seasons of high water. But since that time the two have
occurred in connection with such regularity that the fact has been
noted by even the most unobserving; that is, in season of low water
during the first three or four months of the 3ear, there have been few
gnats, but with high water during these months they were abundant,
reaching the maximum during an overflow.
The banks of the rivers of this alluvial district are peculiar, in that
the country slopes from instead of toward the streams. Hence water,
escaping through the banks first runs inland, and then more or less
parallel with the parent stream, until it can empty its waters into a
larger tributary. Of this characteristic of the Iississippi, Red, and
Yazoo Rivers, whether considered individually or collectively, I do
not think it would be too much to say that it is one of the primary
causes of the production of the gnats in such destructive numbers;
My own observations were almost wholly confined to the country
lying between the Arkansas and Red Rivers on the one hand and be-
tween the MIississippi and Washita on the other. This section is of
difficult access, and I have relied ifor my information principally upon
civil engineers and other people familiar with topography of the coun.
try, as my own time was largely occupied in studying the gnats them-
selves in Tensas Parish.
WAith the exception of a low, wide ridge of country lying between
Detnt River and Bayou Mason, and extending from Franklin Parish to
Southern Arkansas, and known as the Dayou 'Mason Hills, this whole
region is very flat; and the streams, with only rain and sewage water
to carry off, would naturally have a sluggish current. A glance over
the map of this section will show that it is traversed by .Bayous Bar-
tholomcw and Mason, and Rivers B eunf and Tensas, the last two
really not materially differing from bayous.
Three of these will be observed to originate in extreme Southeastern
Arkansasand running south-southwest, finally unite together, and form
Black River, which is a tributary of the Washita.

number of gnats and the amount of damage done by them in the
vicinity of the streams thus influenced.
They appear in the vicinity of Mill Bayou every year in greater or
less numbers, and I have twice observed them being carried from them
to Somerset plantation by a heavy northwest wind, and as often ob-
served them gradually disappear under winds blowing equally strong
from the north, northeast, and south.
Strong winds, blowing from a northwesterly quarter, bring gnats sud-
denly and in great numbers to the neighborhood of Lake Saint Joseph,
six to eight miles below Somerset. Judge Gunby states that they appear
at Monroe with an east wind; Mr. Craig observes them at Point Chicot
with a west or southwest wind, and at the time they appeared in the
city of Vicksburg they came with a westerly wind.
Probably the worst afflicted parish in Louisiana is that of Franklin,
which is situated between and at the junction of Btenf River and Bayou
Mason. Judge Gunby and others well acquainted with the country
through which these two streams flow state that gnats appear with
more regularity and in greater numbers in that vicinity than elsewhere.
Mr. Craig states that they occur to some extent every year along these
streams in Arkansas, being observed the most numerous the present
season near Bayou Mason. This is in accordance with all reliable in-
formation which I have been able to obtain, and, aside from the country
about Mill Bayou, coincides with my own observations.
In connection with this evidence we can also observe that these-
gnats are yearly being produced in numbers close up to the danger
line, only an overflow being required to furnish the conditions suitable
for carrying them far beyond. Soon after these investigations began I
learned that the Buffalo Gnat did not occur below the mouth of the
Red River. Wishing definite information on this point, I addressed a
letter to Judge F. H. Farrer, of Bayou Sara, La., whose reply is given
herewith, and I will only say that the acts embodied therein have since
been corroborated by planters whom I have met from that region :
BAYOU SARA, LA., Mar'ch 9, 1886.
DEAR Sm11: Yours of the 4th instant was received day before yesterday, Sunday.
Court being in session, a great many farmers were in town, and I had plenty of old,
experienced men to apply to for information in regard to the Buffalo-gnat.
Many had been familiar with the mischief it did farther north, but all agreed that,
except to young turkeys and other poultry, it worked little or no harl in this region,
either in low or high lands. A few indeed asserted that the one here was a dilfflrent
insect, known by the name of "turkey guat," but the large majority maintained that
it was the same humpbacked individual so destructive in North and Northwest Lou-
isiana. I presumie that it never appears in such numbers here as there.
My own experience, as far as it goes, agrees with that of the majority with whom I
spoke on the subject, viz, that the genuine Buffalo-guat is to be seen here every
spring for a few weeks, but is by no means the dangerous pest to cattle, horses, &c.,
that it is in Northern Louisiana.
Respectfully, yours, &c.,
F. H. FA-RRAR.
F. M1. WE'RSTEn, Esq., Vicksburg, Miss.

NATIVE PLUIIS.
The Chickasaw Plum (Prunus chickisa) found indigenous from North-
ern Illinois to the Gulf of Mexico, and the wild yellow or red plum
(Prulus americana) found indigenous over nearly the whole continent.
These are two quite distinct races (for they cannot he regarded as dis-
tinct species) of the subgenus P'runus of the Almonld family (Almygdalea),
order Rosacee. And at typical tree of either so-called species is very
distinct in fruit, foliage, and general appearance from a typical tree of
the other. But so far as we are concerned in this study of them they are
practically the same, except that the fruitof the P. americana, or North-
ern type, has much the thicker, tougher, and more acerb skin, and that
some of the Chickasaw, or Southerntype, do not provehardy far North,
i. e., some of the named varieties, while others do, and the saie wouhl
undoubtedly prove true of P. aiericana. But as this last is found grow-
ing wild, and with good varieties, at least as far north as the northern
limit of Dakota, these native plums are a fruit in some of their varieties
perfectly adapted to every part of the United States and 2 erritories and
pre-einently the fruit of the great Northwest.
Yet, as a rule, those v'who have taken these wild plums from their na-
tive thickets and planted and carefully cultivated them, in hope of find-
nlug at least a poor substitute for the Garden Plum, have met with a com-
plete, decisive failure. They got no fruit. We, the older settlers of
the West (Illinois), knew the wild plums as the most plentiful and use-
ful of the wild fruits when the country was first settled and when our
" tame" plums failed (for it is a fact that in this part of Illinois as early
as 1845 we fruited many varieties of the Garden Plum, Nectarines,
Peaches, and Apricots in abundance, with no injury from the Plum Cur-
culio, or rot"). We began to hunt out and plant the finer varietiesof
the wild ones, some of which were most beautiful, large and fine, and
of very good quality. But after years of patient waiting we found that
these gave no fruit in their new homes, except very rarely. We found
that the young fruit developed to the size of a little pea, or a little larger,
and indeed often to more than half its full size, and then all fell off.
This fallen fruit, if examined, showed very generally the ovipositing
marks of the Plum Curculio, made when laying her eggs.
It is not necessary, here to give the complete natural history of this
insect, because all the more important facts and their practical bear-
ings have been recorded by competent writers, and especially by Walsh
in his first report as State entomologist of Illinois, and by Riley in his
third report on the insects of Missouri; but it will be sufntficient to say that;
it is a small insect of the Curculio (Curculioidw) or snout-beetle family
that deposits its eggs under the skin of the young fruit of all the smooth-
skinned species of the Almnond family, or nearly all of them, and some
other fruits as well. The eggs are deposited in little holes eaten through

orous and healthy as they were when we gray-headed chaps were boys,
fbr their surroundings had been changed, greatly changed. Their old
companion plants were nearly all gone; new plants, usurpers, had taken
their places and their environment was changed.
These new plants were many of them very injuTious and detrimental
to the vigor of the trees, and with the advent of man had come his herds;
they tramped the ground down hard over their roots; they laid bare
the surface of the soil to the direct rays of the sun by eating the herb-
age. Things injurious to the foliage and fruit of the trees, in the shape
of new insects and" new diseases, were introduced, but with all of this
a few wild plum thickets survived and matured plums. Why these did
mature fruit under these adverse circumstances, and why the selections
we made of a few fine plums from perhaps some of the most fruitful of
these same thickets could not be made to mature a plum with all the
care and petting we could give them, when planted in our garden or or-
chard, to explain this, to give the reasons why, and to show how easily
all can have this valuable and delicious fruit in abundance, is the mo-
tive of preparing this paper for publication.
And now I will begin my task. I was born here (Marshall County,
Illinois) in 1834, and can therefore well remember the country as it was,
and the wild plums as they were before the Plum Curculio made its
first destructive showing here in 1845. Then we had these plums
everywhere; the woods were full of them." The valleys of the smaller
streams were almost one continuous and unbroken plum thicket from
source to mouth. The edges of the prairies were skirted with them.
They were the most plentiful and useful of all our wild fruits.
As a boy I was passionately fond of fruit of all kinds, and the lo-
cation of all good wild fruits that I could find was stored up in my
memory for future use.
Many of the wild plums, as I remember them, growiugin our woods
were very poor in quality-many good, a few very good, and a still
smaller proportion of them very good and very handsome.
About the year 184 t I found growing in the edge of a plum thicket a
beautiful young tree, with a few large bright golden plums on it, kissed
by the sun until their cheeks blushed crimson, and, when ripe, of deli-
cious, honeyed perfumed flavor, large, oblong, and most beautiful. The
next fall it was fairly loaded with its glorious fruit. I determined to
secure this prize and have it all my own. I took it up very carefully,
transplanted it into the garden, and tended it with the greatest care;
it grew finely in its new home, but never matured a fruit; it bloomed
and set fruit freely, but it soon all fell off, but they were not stung by
the 'lum Carculio It was before the advent in great numbers of
that now numerous pest.
I next tried the European or Garden Plum ; they bloomed, fruited,
but every plum was destroyed by the-Plum Curculio before maturing.

cana type, from seed grown in Visconsin. These were planted in two
blocks and were budded over once with the varieties last named, and
so e others. The rows were four feet apartand the seedlings one foot
(or less) apart in the rows. But a small percentage of the buds grew
tie best of the resulting budded trees were sold, but moreor less trees
of all the varieties so budtdled were left among the seedlings and all grew
up together and are yet, to-day, to be seen in the same condition.
Of the trees planted not near other trees of the Almond family,
number ing some hundreds, not one of them ever matured a fruit during
the sixteen years they have been old enough to produce, until last
season, when'a few of the varieties ripened a very high crop of fruit,
the Miner being second only to the Newman in point of productiveness.
The Newman as an exception to the other varieties has given a fair
crop each season during the sixteen years, except one, when it failed
entirely. Ten years ago I was ready to retire beaten, and give up the
whole plum and plum-tree business in disgust, in fact the whole Al-
mnond family, for the Plum Curoulio seemed determined to destroy all the
cherries also. I had followed every hint and theory that I had ever
heard of. I carefully examined the flowersof all the varieties, and found
them, sofar as I could see, perfect in all their parts. The first grafts of
the Wild Goose in the Miner trees continued to bear each year, as did
the trees in which they were grafted. The isolated trees, scattered
over the plantation), were vigorous, healthy, and each year bloomed pro-
fusely and set fruit freely, but it all fell off when quite small, except a
very small proportion of that on the Wild Goose; some of the fruit of
this variety wuld attain half, two-thirds, or even full size, ripen pre-
maturely and then fall off. But in all such instances there were other
trees of the Almond family planted not far away, and I can safely say
that during the twenty years or more that I have had this variety old
enough to bear, the hundreds of trees of it in my orcharls have not
matured one fruit if completely isolated from other trees of the Almond
family.
One day, when examining the fruit of this variety for Cureulio young,
I was surprised not to find a live grub in them at all, and at that time
could not find a fruit in which the larvwe had ever fed. And I was
still more surprised upon cutting through the shell to filnd that the seed
had not developed and was imperfect. This fact led me to believe that
the flowers of this variety were not perfect, that the pollen was not
good.
Some years ago I received from its disseminator, O. M. Lord, of Min-
nesota City, Minn., scions (grafts) of a fine new hardy plum found in
his neighborhood, uamed tlhe "a olling Stone." Five of these I grafted
into :a tree of Vil dGoose of bearing :age by splice grafting on the ter-
minal twigs of the main branlches. All five of these grafts grew ; one
of them gave three clutterr of bloom the sne sprl'ing it was grafted,

'" Plants and Animals under Domestication," and the same theory has
to some extent been handled in works by other eminent scientists. I
found that theRolling Stone variety would pollenize the Wild Goose and
render it fruitful. I found that other varities would do the same when
twenty feet away, if the wind blew from the right direction when they
were in bloom. I found that in every instance where I had trees of the
liner and Wild Goose near each other, both varieties were very pro-
ductive, and also that when the Newman and Wild Goose were near
together neither was fully productive, and that where Miner and New-
man were contiguous both were enormously and regularly productive.
I also found that where I had Newman growing isolated from other
varieties, that it was yearly productive of moderate crops of good fruit,
but scarcely a seed from such trees would grow ; but where the Newman
and Mliner were planted near together the -Newman was not only enor-
mously productive, but the fruit was larger, later, darker colored, and
thicker skinned, and the seed all good, and the resulting seedlings
strong and vigorous, the Miner being also very productive in this case.
Further, I found that where I had nearly all the named varieties of
both types of these plums growing together in the two blocks of seed-
lings, that all of then (including the seedlings) were, with thile excep.
tion of the \Vild ("oose, very productive each year since old enough to
bear. Trees of the WVild Goose were growing in both blocks of these
seedlings, but nolne of them have ever fruited so heavily as those grow.
ing- near Miner, showing, I think, that the Miner is its best consort. The
trees in these two blocks of seedlings are about one foot apart in the
row, andl the rows four feet apart. (Growing illn this way much in the
same manner as the natural plaui thickets of the earlier days of this
country, they have all of then matured a full crop of plums each year
for the past seven years, and the trees have remained more vigorous
and healthy than isolated trees of the same varieties. The number of
varieties in these two blocks may be safely estimated at 5,000, running
through all grades of the northern wild plum, from the poorest to the
very best. During the whole period in which these plums have been
fruiting, nothing whatever has been done to protect the fruit from or
to destroy the Plum Curculio, and this insect has been present in large
numbers during the whole time. No hogs or other stock have been
allowed to run among the trees, and, until the last three seasous, all the
a wormy fruit has rotted on the ground, undisturbed.
The history of these plum trees tells nmy readers exactly how to fruit
the native plums everywhere in abundance. Heretofore when writing
on this subject I have qualified the above by saying how they will
fruit here abundantly. ut during the past two years I have cor-
responded with the owners of or visited a great number of plum or-
chards throughout nearly the whole country and find the same results
everywhere, namely, wherever these plums have been planted with
several rarities near together (or near trees of several other species of

FRUIT THE NATIVE PLUS
everywhere in abundance. How ? Simply by planting several va-
rieties near together or commingled, or by grafting or budding barren
trees with one or more different varieties as above explained. Plant-
ing the different varieties near together is most practical, and easily
done by selecting such two (or more) varieties as will pollenize each
other, and planting them alternately in rows 4 to 6 feet apart, the rows
running in the direction of the prevailing winds at the blooming time
of the plum. If we do not know what varieties will pollenize each other,
we will be safe if we plant several varieties in close proximity, so as to
have the so-called species alternate in the rows. The rows may be 15
to 30 feet apart.
We now take up the
PLUM CURCULIO (Conotrachelus nenuphar)
understandingly. But why need I add one more word about it for the
proof is absolute here, and I have the same complete proof from nearly
every State and Territory, that it has no effect on the fruiting of the
great majority of our native plums whatever. If their flowers are
pollenized they give regular crops of valuable fruit as any fruit in any
climate, with no material damage to the fruit, except rarely to a few
varieties, by this pest. In fact, I will here put it on record: I believe
that after carefully investigating the subject throughout three seasons,
that what effect this curculio has on these fruits tends to benefit the
tree and fruit rather than injure, for, where these plums are fully pollen.
ized their tendency is to overbear-to set more fruit than they can or
should bring to maturity. The most materialinjury to this fruit by the
curculio is that the cuts through the skin of the young fruit, made by
her when laying her eggs, sometimes forms a nidus (breeding place) for
"fruit-rot." The varieties will be affected by this very differently in
different locations and climates, but this rot does not, as is the case
with some other fruits, so far as is known prevent our securing full
crops of some varieties everywhere. (Curiously the evidence is that P.
chickasa is more subject to rot South than P. americana, and vice versa.
But my observations here prove that this "fruit rot" in the native
plums more often finds a nidus. or origin in the minute punctures of leaf
lice (Aphididre) and plant bug (Hemiptera). The most injurious of the
bugs to the fruit of our native plums, and perhaps the most injurious in-
sect of _North America, is the now notorious tarnished plant bug (alsus
oblineatus, Say.). This pernicious bug is abundant nearly everywhere,
is ,n omnivorous feeder, and not only depletes trees and plants of their
juices, but the puncture of its beak is very poisonous to them, causing
many young fruits to drop soon after being punctured, on others leav-
ing wounds for the entrance of the spores of the sporadic diseases or
"rots." Therefore it will not do to give the plum curculio credit as the

looking larvae in P. americana in the woods, to the number of plums
stung than I have in any other plum, a not very careful survey of this
tree showed that about one in twenty-five of the eggs laid in the fruit
has produced well-grown, healthy looking larve). I selected first 100
plums of the Wild Goose variety, in which eggs had seemingly been
laid. (I am well aware that in many species of insect life the females
will continue to form proper nidi for the reception of her eggs long
after her supply of eggs has become completely exhausted; in fact,
as a rule the grim messenger" finds her busily at work, with feeble
effort, trying to lay eggs and reproduce her kind, and it is quite proba-
ble that our "Little Turk" possesses this instinct, which continues to
its fatal termination. Therefore my percentages are not so correct as
if I had been able in each instance to locate an egg, in eitu within the
ovipositing mark.) At least the ovipositing mark was apparent on
each fruit. These were placed in a vessel, and taken out one at a
time and cut under the ovipositing mark to ascertain if the larve
had fed. If it had not fed noticeably, it was thrown aside and another
taken up, and so on until I had obtained a hundred plums in which
the egg had hatched and the larve had fed. Two trials of Wild Goose
plums, in this way, gave respectively 22 and 23 living, sickly look-
ing, attenuated larne. Two trials of the same number of N ewman gave
respectively 24 and 26 of the same kind of grubs. Whether any one
of these sickly looking larne would have matured into beetles I do
not know, but I have the best of reasons for believing that none of
them would. And here are my reasons, and they are of the greatest
value, if I have made no mistakes. The autumns of 1884 and 1885 I
gathered the fallen fruit from all the trees for seed, and of course in this
way I got all the fruit with living larne in them, and when selecting
what good fruit there was for market, all wormy and imperfect fruit
was thrown on the surface of the ground in the shade of trees, day by
day as gathered, and on and convenient thereto were placed several
contrivances, such as the young beetles are known to seek as soon as
they emerge from the ground for shelter. These shelters were care-
fully examined until cold weather without finding a single beetle.
The next spring this seed was gathered up early and planted. A good
portion of the ground it had occupied was at once covered with strong
canvas, with its edges so covered and fastened down that it was im-
probable that the beetles could escape from under it.* Now, if this 80
bushels of plums selected from the 261 bushels marketed on one season,
and of course including practically all the wormy plums, bred no Curcu-
lios, and it takes 3,200 eggs to produce one well-matured larva, and if we
give it all the Native Plums it may require in which to lay all of its eggs,
This experiment was very poorly conducted and proves nothing. If the plums re-
ferred to were worthy, it is safe to say that at least a portion of the larvae were in
healthy collditioa au1 wolt throtugtl their trusfortuations under ground. We have

beautiful and delicious jellies. Such are the principal uses of the fruit.
The trees will thrive on any soil that will support common trees, but do
best on a deep, rich, moist soil; they thrive finely in the bottoms of deep,
steel), narrow ravines and alongdrains, on lands too rough for cultivation,
if reasonably rich. The trees are natural to crowded situations. crowded
by each other, and by other trees ; their roots do best rambling through
moist soil, shaded from the sun, and the trees do very much the best in
a location sheltered from the strong winds of spring (which blow away
the pollen). The trees are easily propagated; they throw up young
trees (suckers) freely from their roots; therefore when planting these
plains on. the thicket plan in waste places it is best to have them on
their own roots. Or, if we do not wish them to produce suckers, they
may be budded on the Chickasaw variety known as Mariana, which
variety grows freely from cuttings, is quite hardy, and seldom, if ever,
throws tip suckers from its roots. In the South these plumts do finely
when budded or grafted on peach (which do not sucker), but care must
be taken to prevent injury from the Peach Borer (_,Fgeria exitiosa Say).
North they do nicely if "root-grafted" on peach. Generally, as the reader
will have learned from this paper, the Native Plums have no very nox-
ious insect enemies or diseases here or over the country at large, and it
is safe to say that they in some of their varieties or tribes can be grown
profitably in every part of the country. There is a vast amount to be
learned about them as yet, and some very important facts to determine.
The most valuable one is this : I have some proof that certain varieties
of these plums will breed the Plum Curcuilio freely'; if so, such varieties
should be searched out and destroyed, and we should be sure not to
plant these varieties for fruit, be that ever so fine.
THE. SERRELL AUTOMkATI 'SILK REE1 L.
By PHIILIP W ALKER.
In previous reports the new Serrell automatic silk reel has been fre-
quently mentioned, but owing to the incomplete condition of the pat-
ents upon it, it has been considered unwise to publish even such a gen-
eral description as that which follows. Now, however, that these ma-
chines axe in operation in Washington, it is possible to gratify the
laudable curiosity of persons interested in this machinery, of which so
much has been said but so little known in this country.
An understanding of the mechanical principles of ordinary noni-auto-
mnatic reels and of the Serrell serigraph are so necessary to a thorough
comprehension of the automatic reel that, althoug-t they have already
been) described by Professor R~iley in Bulletin No. 9 of the Division.*
it is deemed wise to insert ail account of uhem, here. The quotations

for them to consume at least four pounds of raw material in the forma-
tion of each pound of their product.
Before reeling the cocoons must be cleaned by the removal of the
outer system of threads which, under the name of floss, is one of the
waste products of the industry.
In the filature the "cocoons are first plunged into boiling water,
whereby their gluten is softened in such a manner as to render the un-
winding of the filaments an easy matter. This done, they are brushed
with a small broom, to the straws of which their fibers become attached.
The bundle of filaments is then taken and they are unwound until each
cocoon hangs by but one clean thread. These three operations are
called 'cooking brushing,', and 'Ipurging The first two can be ae.
complished mechanically, and are currently so performed in Italy and
largely in France. But purging is a process to which the accuracy of
the human eye and the delicacy of the human touch have so far been
found necessary." The thread unwound in these processes is also a
waste product, called "frisons," and has about one-fifth the value of
reeled silk. In good working about four times as much silk as frisons
is produced.

F'ia. 1.-Elements of the mechanism of a modern silk reel.
"The elements of the mechanism of all modern silk reels areessentially
the same. They are shown in Fig. 1, and consist, in general, of a basin,
A9, in which is a perforated steam-pipe, P, by means of which the water
in the basin may be heated. A few inches above the surface of the
water is placed a perforated agate, B. The cocoons having undergone
the three operations mentioned, the ends of the filaments of four or more
of them are twisted together into a thread which is passed through the
hole in the agate. From this it runs through the croisure 1 f, which
will be hereafter explained,l and over the guide E to the reel at F. Be-
tween E and F the thread passes a guide, G, moving to and fro (in a
line perpendicular to the plane of the paper), which distributes it in a

The thread of 1raw or reeled silk is excessively strong, duLctile,an
elastic. As has been seen, it is composed of several double filaments,
drawn from as many cocoons. In common with other elastic threads,
a given length of one of' silk will resist a tende'ficy to stretch to ail ex
tent proportionate to its mean sections. This is the underlying princi-
ple of the serigraph. The mode of determining the irreg4u lari ties exist-
ing in a thread of raw silk by means of this machine is as follows: Th'e
end of the thread is brought from the reel or bobbin on which it is wound

around a drum, S, (Plate I), thence over a pulley, R, and back around
another drum, T, mounted on the same axis as S. From the drui T it
is wound onl a reel. The drum T is larger than S, so that the former
winds on the thread somewhat faster than it is paid off by the latter,-
and thus stretches it. In this manner we apply a constant force to the
pulley R, tending to draw it from its normal position. This pulley is
attached to the base of a pendulum, U, which, under the action of the
force mentioned, is drawn from the perpendicular. The weight of' this
pendulum overcoming the force thus applied to an extent inver~sely pro-
portional to the mean. section of the length of thread submitted to the
test the position of equilibrium taken by the pendulum depends upon
and is anl indication of that mean section. The portion thus tested is
that between the two drams S and T, and as, through the constant
action of the machine, successive lengths of thread occupy the position
indicated, the pendualuin oscillates through a course which depends fipou
the irregularities of the thread. These irregularities are graphically
recorded by a pencil, attached to the pendulum, upon a band of paper,
which moves constantly under its point.
The serigraph, it will be seen, is an apparatus for continuously mneas-
uriug the relative size of any thread passed over its drams and record-
ing the irregularities in its size onl a band of paper.
From this machine to the automatic reeler was but a slight transition.
easily accomplished. It has been in working out the details of the de.
sired mechanism that the greatest difficulty has been met with. The
result is attained in general by causing the pendulum U to close an

of a magnet to whose armnature't is attached(1 a1 detenit which, whl no
current is passing. prv~vets the rotatiAm iof t he camn.
-Now, as we have see" above. nio current passes through the electric




circuit while the thread is at its standard size ; for under such condi-
tions the lever is so held by the thread that the contact at a is kept
,open. As soon, however, as the thread diminishes in size the lever
recedes, the contact at a is closed, and the current passing through the
magnet of the feed movement IV causes the attraction of its armature
and the release of the detent holding the cam in place. Upon this occur-
ring the magazine is advanced one step and brings a new cocqon filia-
ment into the path of the hook on the filament attaching device, which
catching it up twists it around the running thread and, with the help
of its natural gum, attaches it firmly thereto, at the same time cutting
off the loose end. The rotation of the cam is so timed that its detent
will Dot arrive at the stop on the armature until the new filament has
reached the controlling drums and bad its effect upon the position of
the control lever. In the reeling of fine sizes the addition of one fila-
ment will generally be found sufficient to bring the thread to its normal
size, though it is less apt to be so with larger sizes. In any case, how-
ever, if, when the rotation of the cain is completed, the electric circuit
still remains closed the action of the feed movement is repeated and con-
tinued until the thread is again brought to the normal size.
Owing to the irregularities in a thread of raw silk it is impossible to
obtain any measure of its size by means of a caliper or even, with any
degree of ease, by a microscopical examination. Merchants are there-
fore obliged to content themselves by approximating its size in the fol.
lowing, manner: They measure off upon a suitable real a skein of a
given length (476 meters) and obtain its Weight ill the terms of an arbi-
trary unit called the denir. If such a sample skein, for instance, is
found to weigh ten deniers it is called a Iten-denier silk." Now it is
found that the exterior thread of a, cocoon of the yellow Milanese races
has a value of about two and a half deniers, so that it takes four such
new cocoons to make a thread of ten deniers. When these cocoons are
half unwound the size of the thread formed from them woul be buitabout
eight deniers. :Now, in order to augment the thread and bring it to the
normal size we are obliged to add another cocoon which, with its new
thread, would increase the combined thread to ten and one-half deniers,
and it will be seen that from cocoons of this race it is impossible to
augment the thread by smaller increments than that mentioned. :For
this reason no attempt is made to produce an absolutely regular thread
of silk, but reelers are content if the variation from the desired mean
does not exceed two deniers in each direction. In hand-reeling, where
the regularity of the thread depends entirely upon the ability of the
reeler to estimate its present size and to add a new filament at the
proper time, only the most expert operatives are able to make silk with-
in the limits named. In the automatic reel, however, all this is taken
out of the bands of the operative and the indication of the need of a new
thread is made by the delicate serigraphic measuring device of the con-
trol movement. Its delicacy is such that when working under good
