cies, and our economic literature to-day is d;oubtlese nwre
than that of any other country.
Most fortimately traditions and theories have bad but'lfttk lit
in applied entomology. The accuracy of- published statemeoU,,'
cerning the life and habits of insects and the valut of remoffial
ures proposed have often been at once put to pradiml test and
smindness or futility determined. Investigations by soveml di
workers over a considerable range, of territory have been -a
fertile means of rapid accumulation of knowledp
biology of a given es and of the means to be used in
ravages. Much of error, in theory and iin practice, which nuight
wise have lived for many years with a corresponding banefal'
on the standing of the science has thus been quickly eliminated.
Our official existence has been strenuous, and, were it not foir
iderable munber of investigators often engaged on the
problem and the immediate practical test of conclusions, our raU,''-
progress could but mean superficial work. Many of the
with which economic entomology concerns itself must be worked
from the beginning, and many of our economic workers have
forced to do strictly systematic work as a liasis for
work along economic- lines. Thecommon observation that a
science does not wait, in its development, on the theoreticaRy
sary precedence of the pure science on which it is dependent *19,
haps nowhere so well illustrated as in the case of applied e
Of neoe&sitv many of our workers are systematists, and their a
plishments in this field are scarcely less than i n the domain
practical entomology. In addition to having an acquaintance *%K,'
the details of insect classification and with fundamental b
facts, an economic entomologist must be versed in the detaib'
agricultural and horticultural practices, in chemistry, in botany'.
forestry, in plant pathology, in animal husbandry, and in bil-i
methods.
Under conditions and requirements such as these has applied
mology grown to its present condition; and, although young in
there is probably no branch of the utilitarian sciences whidt so,
touches every human interest.
There are at the present time some features of applied en
in the United States which are significant of its inenmLsing scope

the San Jose scale or the boll weevil leave but little alternative to zi',
sufferer, and while the experience is costly, the lesson is well learn
In the writer's opinion, the notable improvement in this direwoti'
during recent years may be held to prophesy a rapid increase intt I
adoption of insect remedies and preventive in the future.
The extent of increase in the number of workers in eoonoi4
entomology during recent years may not, perhaps, be generally reul'
ized. As nearly as I have been able to ascertain, there are at prsent,
in the United States nnd Canada, 145 persons trained in methods of
entomological rnsenrch, devoting the whole or a part of their time to
the sti(ly of injurious in.ects. If account be taken of the manyi
insJi)ectors employed by various States and State horticultural orpni.

cently, interesting comparisons have been made by Professors Webst*
and Slingerland of losses to crops in certain tates and the country
at large as compared with the amounts of money required for' the
support of our various institutions. Thus we "are told that' thi,-
annual loss occasioned by insects in the United States amounts t6
more than is required for all educational purposes; nearly twice a*-,,Y,
much as is required for the support of our Army and Navy; ovoi
twice the losses from fire, and nearly three times the estimated valu,6
of the products of all fruit orchards, vinevards, and small fruit farmr04-
in our country.
Careful e..-.,timates have shownthat the total annual loss from inseo*.tt-i,
de predation in the JTnited States at the present time is not less th M11
$3001000)000. In the face of such figures it would appear that vel
have scarcely entered the threshold of achievement in conqueiiast
injurious species.. It-may not, however, be argued from the figuredt
given that little has thui t -
far been accomplished. It will be =ewtl
I)ered that years ago, in 1860, insect losses in the country at I
were placed by Walsh at not less than $300,000,000 annually. 11,
these, estimates are correct the losses appear to hive been held stat
tionary, notwithstanding our great agricultural development durint-
theJorty years. intervening. Present-day estimates are based on a
10 per cent reduction of all crops by the combined attack of the vari-'
MS 1.61,Tecieswhich prey upon them. In Walsh's time the perc,6ntap
of itjjury must have been inuch higher, as determined by the value of
farm product-s at that time.

era in the evolution' of, methods of insect control. Suth a,
expedient as delaying the time of planting wheat so &s to.
injury from the fall swarin of the Hessian fly has been the weatw.
saving millions of dollars to the wheat growers in the
infested with this insect.- The imporiant work on this species,
Doctor Hopkins pemifts the.deterniination of the normal
appeamnee of the fall brood for arty latit-nde or altitude.
Webster, by observations extending over.. many, years5lbas been-
chart the State of Ohio into belts in'dicatm*g the safe periods for.,
4
planting of this crop.
The recognition of the value of late fall or winter plowing, of
tion of crops,, of certain classes of fertilizer, and of better culti
in the control of noxious species will make this class of work
important in th future. During the lastfew years the im
of improved cultural methods has been demonstrated on a large 9ftloe';
in the control of two serious pests of the cotton plant, namel, 1"A'
boll weevil and the bollworm.
In the case of the cotton boll weevil its advent in the cotton fie1c*,,,,g
of Texas coincided with conditions of cotton culture which greatly,,"*
aggravated its destructiveness. The natural fertility of the
and the tenant system largely in vogue had broftght about an indiffer.-
ence to those economical methods of farming found necessary in older;
sections, where the fertility of the land is less and the difficulty, of
producing profitable crops is greater, Indifferent preparatioh and
cultivation of the land, the use of unselected and more or less
down seed-often from the public ginneries and of absolutely
known variety-had placed the cotton-growing *industry in a condi-
tionilo be seriously threatened b-y the introduction of any'inimiad
factor. The remedial measures now found necess-aryare along the, line,
of better. farming, and we have the not unusual case of entomologist*
showing the fariner how to farm. The success with which this work
been carried out must in part be attributed to the. i-eadiness of
landowners to adopt methods which they recognized as- practicable
and desirable in themselves say nothing of their value in circum-
venting weevil injury. In a recent -communication from Mr. W. D.,,
Hunter, in charge of the cotton boll weevil investigations of the-4 'Le
Bureau of Entomology, he mentions certain phases of his work which
are pertinent here as bearing on the methods and extent of this cul-
tural work as applied to what is one of our most important preseni
day insect problems. He writes as follows:
During the several years that the Bureau of Entomology of the United StateS
Deplirtment of Agriculture has carried on Investigations of the Mexican -cotton
boll weevil It has been possible to perfeLt a syRtem of avoiding damage by the

A most commendable feature of our present-day literature is the .'
increasing amount of thorough and painstaking work on the biology .
of insects. Shortly after the establishment of the several agricultural"...r
experiment stations entomological publications were, probably of
necessity, largely compilations, owing to the fact that there was need.-..i:::.
for placing before the public for immediate use such information. -li
covering injurious species as had already been obtained. As informa:.- .
tion of this character has become more and more familiar, its presena- |i
station and repetition have become less necessary, and more original .:
work has been brought forth. Revised bulletins on insecticides and.
spraying machinery must of necessity be gotten out from time tQ:-
time as progress is made along these lines, but the notable decreased
of purely compiled bulletins and papers concerning insects is a mos*l.:.
favorable indication.
Many recent entomological publications, in the quality of subject- :i
matter, character of illustrations, and wealth of detailed observations
leave little to be desired. Improved facilities for careful life-histo.iyl
work have rendered possible the many excellent papers which are at.::
once a credit to the literature of the science and an inspirationto
other workers. Careful life-history studies have been an importantt^
means of separating two or more species long held to represent bin.;:
one. Witness the case of the aphids designated as Aphid mali, whi+ &
Sanderson has shown represent several species. Similarly, Morrill '
has been able to separate Aleyrodes packardi from Aleyrodea vapora- i
riorum. Certain species may only be distinguished by a compara-i|
live study of their respective larval stages, as in the case of ChMilocoriw.
bieulnerus and C. smims. .
In addition to careful biologic studies of insects, the consideration

scale as any of the lime-sulphur washes. It has several advantagL.':
It requires no boiling, and the sal soda is a common material, easily "
handled and obtainable in almost every locality. It is also a little^^
cheaper, as the amount of sal soda necessary costs less than the quanY:i "Iil
tity of caustic soda advised for preparing 50 gallons of wash. This'i
material has been used but one season, though it was tried in seve ral,
localities. Professor Lochhead, of the Ontario Agricultural Col..i.:"

sulphur washes, and a few others obtained, from good to excellent: ,
results in spite of their inability to give it a thorough trial.
In this connection it might be well to add that experiments were .I

NOTES ON CUBAN INSECTS.

[Abstract.] .. I
The short time the writer has been in Cuba makes it impossible to J
give more than a preliminary report. Natural conditions are favor- ......
able to a multitude of insects, and this report will be confined to :
those of economic importance. Lepidoptera are among the most:
conspicuous and many are very destructive. Cutworms are vej
numerous, especially on corn and tobacco. They are frequency::::::
parasitized by dipterous and hymenopterous insects. Leaf-minerl M/1.2

qf#4 f604 early the fall y cm be stamed



















was immediately arrested whenever the mean daily temperature :::::
dropped below 60, and a comparison of this daily record with the ..1
temperature curve platted for College Station shows this strikingly. ::
The number of weevils entering hibernation will depend almost
entirely upon the food supply during the fall. Whether there are
one or two more broods in one part of the State than another matters ;!
not, for after the third brood the weevils become so abundant that
their numbers are limited only by the available food supply. There- i
fore, with a normal or excessive rainfall during September and early
October, which would cause the plants to square freely, there would ::
be an abundant food supply and many more weevils entering hiberna- i
tion than in a dry year when but few squares are formed. The
weather of the fall, then, has a considerable influence on the number "
of weevils which commence reproduction the next spring.
At present one of the most important natural factors in reducing .
the food supply of the weevils in the fall is the leaf worm,'or so-called
"army worm" (Alabama argillacea,'Hiibn.). It is a most interesting
entomological phenomenon that this insect, which formerly did so :
many million dollars' worth of damage to the cotton of the South and
which was the subject of much investigation, has now become one of.. -
the Texas cotton planter's most valued allies and is welcomed by him '
wherever the weevil occurs. That the defoliation of the plant by ......i..
these caterpillars has an important influence on the number of weevils,'::,
hibernating is certain. ..
Of course, the same results are accomplished by thoroughly grazing 1
the cotton, or better, by cutting and pulling the stalks, and the .I
latter forms the most important feature in the fight against the pest,',. .
as discussed hereafter. As far as we can ascertain, the number of 1
weevils entering hibernation will average about one per stalk; in
badly infested fields it will often be two per stalk, and it may be as low !
as one to two stalks, with cotton planted an average distance apart. ;
Where the stalks are allowed to stand, many of the injured bolls : i
remain on them unopened during the winter, and in these the imma- i|ld

Hinds have indicated that about 15 per cent survive at Victoria, l.Ask. i)
the data available would indicate that this is usually about the p.........-.L
centage for southern Texas. At College Station, however, exteMniv
observations show that normally only about 2 per cent, and rarelyr| Y
over 5 per cent, survive in the field; or, in other words, but one-fi::.fth .,,
as many as in southern Texas. That this is a most important factr.
in determining the possible amount and time of damage the next^^:^
season is apparent. If a similar difference is found between centralg i*IT
and northern Texas it will be a matter of great importance for the 'I"
latter section of the State and other portions of the cotton be..t.:^^^,
Careful estimates of the number surviving in southern Texas during
the last winter show that in Lavaca County fully 30 per cent, Or'.,^^
twice as many as usual, survived. With this number appearing in I
the spring, amounting to about 2,500 per acre by actual count, it is ',
impossible to raise a profitable cotton crop by any means now known. ,
As a result, for the first time since they have been infested, the .:
counties of southern Texas, which have heretofore showed no marke,:;I
decrease in production owing to the weevil, produced almost no crop.,
The method used for determining the number of weevils surviving :.:"|
was to count a large number of stalks in the fall at time of hiberna- -':`,,,
tion and determine the number of weevils per stalk; then, in th'..ei:
spring, to count them in a similar way until the first summer broo. ..".ii!
commenced to emerge. In this way the number of weevils per acre,:,
)both in fall and spring, can be very accurately determined, provided :.M:
large numbers of stalks are counted in several fields in one vicinity; C
and we believe this to be the most accurate method of determining tNe:: *:..:
actual mortality which takes place in the field under natural coft- ,.l
editions. r
The time of the greatest mortality is a matter of some interest. As -::: :::
nearly as can be judged from the meager data now available th

to that represented by A"BC', which would be determined by an
A"ZXY, in which the position of the line XY must be determined by compd
tion, with mathematical formulae; and upon establishing its position -l
it confines an area in A"ZXY equal to A"BC', the point X will be the daW.:

The curves given are of interest in that prior to the presentation ofUt

above method as being between May 9 and 12, according to slight varlstI
from above in method of determining. Since then, in January, 1905, i1
author has received Farmers' Bulletin 211, in which Mr. W. a. Hunter simW
on page 21, that the maximum emergence of the weevils In 1904 was on M
l1. which fact was previously unknown to the writer. The close approxSlI
tion seenims to lend support to the probability of the hypothesis In general, .
it has similarly proven correct In at least three other instances. :

there would be 50 weevils, and these would produce by Septemiber
1,250 adults. In other words, the second brood would be twenty
times and the third six hundred and twenty-five times the numbeio
the first. But although we have three broods in the field during "
time the increase is by no means so great. Were it so no cottonvn
be raised. The increase of the second brood over the hiberaiW
broo(l is considerably less than twenty-five times, usually not o'
fifteen times, and the total increase from June 1 to Septeminber Iii
only about fifty times-certainly not over sixty-five times-inst4
of six hundred and twenty-five times, as it should be theoretioj
The reason for this discrepancy is unknown to the writer, but r
the planter may be exceedingly thankful. It may be that (1) t
mortality of the immature stages is greater than determined, whit
we decidedly doubt; (2) many of the adult weevils die or are f i
stroved before reproducing; or (3) the number of eggs laid and ti
length of period of oviposition actually occurring in the field M.*

THE FALL WEBWORM PARTIALLY DOUBLE-BROODED II:
CONNECTICUT.
By W. E. BunTroN, New Haven, Conn. "
EW'N-
In 1901 the fall webworm (Hyphantria cunea Drury) was more':....
abundant in Connecticut than for many years, and, although still
present in destructive numbers, has decreased each year since. For:
some time I have considered the species to be double-brooded, or par- .;.
tially so, in Connecticut, but had not been able to make any definite
observations that would help to settle the matter. A statement to ..:
this effect was made in my first report as State Entomologist. :' A,
similar statement was made at the annual meeting of the Connectict:ai
Pomological Society, at Hartford, Conn., February 4, 1902.b
In the Yearbook of the Department of Agriculture for 1895, page,
376, and also in Farmers' Bulletin No. 99, page 20, Howard statii.'
that the species is double brooded south of New York City.
According to Fernald. there is no satisfactory evidence of moR:.:
than one brood in Massachusetts,o and Mr. Kirkland informs me that. .
the insect has been carefully studied at Amherst and that only one w
brood occurs. I,
On June 23, 1904, the first nest of the season was found in a pear,,':'
tree in Westville, near New Haven. The nest was small, and the..:-..

regard the above probability in the light of a fact. As you all kw i ,
the leaves of nursery trees, as well as the more tender leaves inM
chards, are curled by this pest, and the growth of the tree checked: ii|:`
the time being. Last summer in Minnesota the insects began the
work early in July and soon grew very abundant.
Mr. Stedman, of Missouri, who was present at the meeting ini06
Louis, chanced to remark upon his work along this line in his Statsi."
This coincidence was' a great help to me, for I at once proceede:d 6*l.t
get suggestions from him, which were most cheerfully given. lb.,
general plan of his spraying machine I carried home with me, W4::'.
ing, upon considering the matter, that this plan should be chaeag
somewhat to better subserve our purpose in Minnesota.
It is to be noted that 3- and 4-year-old trees in Minnesota are:: t
as tall as they are in Missouri, hence we were not obliged to Mn_1
the cart quite so high above the ground. Wre found it best, a
to bring the container off the platform which stood above the whaci:N
in order to make the cart more stable. The wheels of this cart cMi--.
5j feet in diameter, with 4-inch tires, and the platform, whid'ck:h:i
Sby 41 feet in size, is 14 inches above the wheels and firmly bWii
anced on the axle, so that practically all the weight comes oi t1i
axle and not on the horse.
A glance at the accompanying illustration (fig. 2) will give cuwe
an idea of the'details. The pipe (D) is a 1-inch pipe 10 feet long.; I
On this pipe four nozzles are attached, pointing directly dowuwiu.t.
and so placed as to be 34 feet distant from each other. This spacng
brings each of the nozzles directly over a nursery row, where, a.u ':in
Minnesota, the rows are usually 3* feet apart. This pipe can tp.
raised or lowered mechanically to suit high or low trees. The hiri
zontal pipe (C) is 14 feet long and projects 10 inches back of : i3
platform, thus clearing the wheels. The five verticals from this pi|pW|
(E) are made of f-inch piping, 5 feet 4 inches long, and there is isic"
a 34-foot space between these. The crosspieces at the bottom aremil:l
arranged that a nozzle in each end of each piece points up atn
angle of about 45. This spacing and arrangement of the nonmulaim
on both pipes results in a copious spray coming both from abovOSi.
upon the tops of the trees and from below against the lower surfmaiw ,
of the leaves-the latter, as you know, being very important. li
actual practice the trees are completely surrounded by a fine spra:,..

und(lue strain. However, as before stated, the weight was so..
balanced on the axle that the outfit was not at all severe o::::
horse and was drawn with apparent ease when the tank wa .....
one-half to two-thirds full.
We had planned to spray early in July, but owing to delay iii
ting the cart completed the first spraying was not given until A**jl
14. At that time kerosene emulsion was used at the rate of 1 pu: .
stock emulsion to 12 parts of water. The machine worked perfe ii,
one man and one pump being sufficient to envelop each tree in: tiei
row in a complete fog. In this fog were thousands of hoppers A
ing from the trees, but unable to escape the spray. This strength of
emulsion, however, while it killed the young hoppers, did not petI
manently affect the adults. On July 19, therefore, we increased the1:!
strength, using I part emulsion to 10 of water. This in no way u
jured the trees, nor did it, unfortunately, kill the adults, which wer:i::
very numerous at that date.
Learning from the Missouri station that they were using a mechan:!:i`:
ical mixture of kerosene (10 per cent) and water with considerableW!
success, 1 sent for a kero-water pump, which is shown in figure 2 (at. .
the right) fitted to the platform. The writer has yet to see one Ofi
these kero-water machines which pumps true to the indicator. Oc::::.i:::
experience has been that if the indicator points at 10 per cent one i::iis
not at all sure of obtaining that percentage of oil in the water; m."i
fact, he is quite sure not to. When the indicator of our pump "in-
dicated" 20 per cent we found by actual test that we were pumping
10 per cent, and 25 per cent indicated gave only 15' per cent. With.:.':
the indicator at 30 per cent we obtained 25 per cent, while 50 per ceat,:::::
on the indicator gave nearly 50 per cent by actual test as it came from::.......'
the nozzles. The indicator's 10 per cent and 15 per cent gave such: :4: ...
small percentage of oil, far below the figure indicated, as to be prac-
tically worthless for our purpose. We found, further, that when t∈,.'
oil in the oil tank got quite low the percentage materially chanasi.S
For instance, with the indicator at 25 per cent we pumped 15 per oa
steadily until the tank was nearly empty, when test showed that w&:
were getting only 5 per cent. This inaccuracy and variation is corn ^^^
mon to all the kero-water pumps with which I have had experie"ce |
and is a serious objection to their use. Nevertheless, once understoodi
and frequently tested in the field, these machines may do good service:. ?J
Our kero-water outfit arrived too late in the season to be of remi tl!
practical benefit. It was used August 5 for the first time, and kr
water with 15 per cent of kerosene was applied. At that date tig
hoppers were becoming decidedly less in number, and, further, ..

The second embryo had evidently inhaled the fumes of the n41
thalin through the thin membrane or the micropyle. This experi*fq
seems to demonstrate that naphthalin does not retard the growthi
the embryo in the egg, but does prevent the young larva from emui
ing. When laid, the eggs are soft, with a membranous covering .
training the whitish granular fluid, and measures 0.60 nmm. in lefi
and 0.29 mm. in width. They are bare, except at the blunt ew
where hairs occur. At the time the larva emerges everything in:' *
egg has been taken up and only the thin outer membrane or skin i
mains as a wrinkled tissue. The accompanying sketch (fig. 8) w

An examination of the vineyards along Lake Erie made duri
the early summer showed that the grapevine rootworm (Fidia nwit O
Walsh) was not as injurious this year as in the past. This was f1 u 6
to be true in sprayed as well as unsprayed vineyards, and also whmi
the vines had been totally neglected. Some growers are of the -Oir
ion that the one reason for the small number of beetles present is that
all the roots near the surface of the ground have been destroyed#
hence the larvae on hatching have nothing to feed upon and die before
burrowing a' sufficient distance to reach the vigorous roots. As-'
- worst infested spots are found where the soil is of a sandy chanfto*I
and as examinations have shown that considerable digging is.
quired before any tender roots are reached, this may offer a part:
explanation of the small number of beetles that developed this .4

to wheat from time to time, we have good reason to suspect that -bA
of these are in Minnesota at present. Professor Lugger report .....i
frit-fly as injurious in 1893 and 1896. ..........
Chinch bugs (Blisus leucopterus Say) have been conspicuous i,,,or,
their absence during the year, no injury whatever being reported !iii &
any county. During the wet weather of last fall I found "arg
number of dead and dying chinch bugs on the station gTroiis,

most of the chinch-bug areas, is possibly, in part, the reason why i.ii

The Mediterranean flour moth (Ephestia kuehnieWla ZelL); -;u:rin.
doubtedly present and increasing in numbers for the past seveS.iifgf
years in Minnesota, has this year made its presence so conspicu :::im
in certain mills as to call for some special work on the part olf thi
Entomologist, and the publication of a special report on the subject i.
for the benefit of the four hundred or more flour mills in Minnesota; i
The leaf-hopper 9Empoasca mali LeB.) is becoming more and Imo n'I:
evident in nurseries, and causing losses annually. We have do* :;iP
some special work against this pest this season, an account of which, i
forms the subject of a previous paper. The work is purely `prelimi Z..,i

with certain field apparatus.
The plum curculio (Conotrachelus nenuphar Hbst.) is provi4
itself almost as great a foe to apples in Minnesota as it is topl1mMi+,,
and is as much of a pest in this particular as is the codling moth.

XIBOELLANEOUS NOTES FROX TEXAS.
By A. F. CONRADI, College Station, Tex.

With the present interest aroused in entomological work in Texa4
inany varied problems confront. the entomologist. No attempt wiU
be made here to review the work for the year, as it will, be elaborately
discussed elsewhere in a short time.
Under date of November 20, Epicauta penn8ylvanica DeG. was
reported to injure onions' in southern. Texas by eating off the tops
near the ground. The injuries this season were not serious, on
Rccount of the small numbers of the insect, but they give ground for,-
apprehension in case the pest be numerous another. year.
Oncideres cingulata Say.has attracted considerable attention, es-
pecially during November, Its work is well known, althongb its
life history has not been worked out in Texas. Near Independence
it attacked pear and rose, doing serious damage. Experiments
with trap lights were made here with apparently good results, for
inany beetles were thus captured. In this locality it injured apple,
peach, and persimmon. Near Manor it injured rosebushes, salt cedar,
backberry, elm, pecan, and cotton. Near Bellville the pear was the e
chief object of attack. Picking the fallen limbs was a remedy used
this season.
The San Jose scale (Aspidiotu8l pemllet*os-us Comst.) is at present
definitely known in eight different localities in Texas, representing
almost every section of the well-settled pprtions of the State. With
the rapid growth of the State in fruit growing and with no iuspeo-
tion laws, it will be but a short time before this will become one
the most important of its many insect problems.
The sweet-potato weevil (Cylas formicarius Fab.) is seriously
threatening the sweet-potato industry in several loc.alities. It W"
first reported in Texas in October, 1890, by T. H. Edwards, Bay View,"
Harris County. The same year the sweet-potato crops around Burasi
La., were reported a failure, owirtcr to this insect. At this writing,
it is known in this State from Bee Caves, Hankamer, Pmdena, Cedirl. -

Mr. Gillette felt it a duty to test an insecticide
believed that it was liable to do injury to the people of his owu,
Mr. Burgess called attention to the fact that we often knew,
testing, that a remedy would bea failure, and yet, in order to
the people and have them follow our recommendations, it was,
sary to make an actual test. For instance, ther6lad been in
Rpanacea for pear blight and peach yellows, which was to be um4,
washing the outside of the trees. ;Uthoug4, of course this coul(a."
possibly be efficient, it was necessary actually to test it.
Mr. Fernald believed that the testing of proprietary

them, yet the people. of the country have a. right t6 know of,
existence of good preparations. He believed that in each of the
divisions of the country one station might assumethis testing A
certain period, others taking it up afterwards in rotation,
Phillips felt that this should be done. In Virginia it appeared'to
necessary to give this information to the -people to protect them
fraud, but it was impossible to test everything. Mr. Quain
called attention to the fact that the Association of Official Agr
tural Chemists has such a system of cooperative tests. Mr. Slinger- P
land believed that even after these tests were made many
would not believe in them. They want to find out by their
experience what the truth is. Mr. Surface dissented from th A

Mr. Fernald moved that a committee of three be appointed to

ties. I have not found it upon either thesugar maple (Acer

were surrounded by the soft maples, except in such small numbers
to be very inconspicuous.
The work of spraying began the middle of July and
until September 1. The work was done undet my constant
vision by some senior students of the Michigan Agricultural
Two outfits on wheels with hand pumps were used, these being'.

top by climbing the tree, finishing at the bottom limbs. The wdW
was thoroughly done, so far as possible every leaf being covered.
When I first took hold of this work I had expected to kill the ih,,'.
sects readily with a weak kerosene emulsion." All the entotiiolo,-
gists said this was the remedy, and my own fourteen years' experienm
.in practical spraying work told me the same thing. I began with K4
8 per cent kerosene emulsion, which was increased within a few days
to 10 per cent, then to 12.1, and finally to 15 per cent. Practliadlr.
none of the insects were killed with either the 8 or 10 per cent. emul-_`
sions. An examination at Professor Forbes's office of leaves spmyvd
with 12j per cent, some days after, showed that something over* 50
per cent were killed, but the death of some of these was doWAUwd
from natural causes. The 15 per cent emulsion killed the gr6a*,
portion of the Pulvinaria, but as this strength took pmetically -an
the leaves off the box elders, all from the lindens, and fully r
from the maples, the remedy.was at least equal to the disease.
per cent emulsion is all that can with safety be applied to the fil'
or box elder, while a 12.1 per cent is all tha t can safely be applied W
the maple.
In this connection some experience in the making of thi ein
may be of interest. With 2,500 large trees to spray, scattered
large. territory, the matter of making the emulsion was of Coil
able importauce. But, as 11 necessity is the mother of invention,"j

Mr. Sanderson spoke of the possibility and desirability of 024t*k
being some publication which could be regarded as the
organ of the Association and in which members could publish
nomic notes and papers. It was moved and seconded that a
mittee of four be appointed to consider the feasibility of ma
arrangement with Entomological News, similaf to that now
between Science and the American Association for the Adv
of Science.
The motion was carried, and the chair appointed as such
Messrs. Skinner, Sanderson, Smith, and Titus.
The following paper was present(4:

LIFE HISTORY.
The adult insect is about 2.5 millimeters in length and of a
gray color, tipped with black on the posterior end. When
flight the wings are folded close to the body. The length of lw*i.
the adult stage is probably not more than forty-eight hours, and AeU
improbable that the insect travels to any great distance, unless carivid"
by air currents. Within twenty-four hours after emerging frot'*O,'
pupa the female insect punctures the upper surface of the young 1it
and deposits her eggs. In fact the adults usually emerge from
pupa during the night and deposit their eggs during the
night. It is possible -with the unaided eyeto see the small slits in
leaves, and they are clearly visible with the aid of a small hand
Within four or five days small black spots surrounding t& punduris

cate the area through which the mesophyll has been destroyed..
quently the punctures are so close together that the galleries b6oom,
united into one very large area. Insome cases every leaf on a pknC
is affected and many of them are entirely destruived. Young
are often entirely defoliated.
After about three weeks within the leaflthe larvab cut their way wtt

in the form of a letter H with a very broad crossbar. Betweeti
web and the surface of the leaf the small pupa is formed.- The
and the pupa.are very delicate and are so placed on the under
of the leaf that they are protected from the excessive rains ot
rainy season. Within three to seven days the adult moth: cwom4ems
the pupa, and the life cycle is complete.
TIMATMENT.
The location of the larva within the -leaf makes, any trestmea6k
this stage practically impossible. However, the delicate
of the pupa furmishes a vital point for attack, and experiments
