I have to exjiretw my thanlcH to Dr. Janu-K Fletcher. Dominion KntomoloKJsi
and the Her. (}eo. W. Taylor, of Wellington, for at.HlRtance reudentl hi revlslim

all riucli I ask the ln(hilKen<e of the public.

Kellow. In hlH lutnxluetiou to "American In«ectR." «.<vr:
" ThnniKhoiit this book reference is constantly made 1., the injuries don.,
by insects to our forest-tnH-s. flowers, fruits. veRctables and grains. The
millions of dollars lost annually l)ecauw> of the sap-sucking of the San Jose
scale, the graiM-phylloxera. the chinch-bug. and the Hessian fly. and the biting
and chewing of beetles and cateri)lllnr8. grubs and borers, are a sort of dlrwt
tax paid by farmers and fruit-growers for the i)rlvilege of farming and grow-
ing fruit. If this tax were levied by Government and collated by agents with
two feet. Instead of being levied by Nature and colle<ted by six-footed agentx
what a swift revolt there would be : But we have, most of us. a curious
Inertia that leads us to suffer with some protesting complaint but little
protesting action the ' ways of Providence.' even when we fairly well recognise
that Providence is chiefly ourselves.

"When we reflect on tiie four hundred millions of dollars a year lost to
our pockets* by Insect ravages, we may incline to believe that the only kind
of Insect study which should claim our attention is the study of how to rid our
lands of these pests. We may be excused for affirming of bugs, as was sal.l
of Indians by some eplgramnuitlst. that the only gootl ones are the dead or.es
When, however, we learn, as we are learning in tliese present davs. that
Insects are not simply serious enemies of our crops and purses, but are truly
dangerous to our very liealth and life, we must become still more extravagnn't
In our condemnatory expreho.oiis concerning them.

" We have long looked on mosquitoes, house-flies and fleas as annoyances
and even tormentors, but that each of these pests actually acts as an inter-
meiliate host for. and Is an active disseminator of. one or more wide-spread
and fatal diseases Is knowledge that has been got only recentlv. Mosqultoc-s
help to propagate, and are, almost certainly, the exclusive di-ssemlnatlng agents
of malaria, yellow fever, and the various forms of fllariasls; house-flies aid
in spreading tyi)hold fever and other disea-ses; fleas are agents In dlstrlbutln-
the germs of bubonic plague. Other Insects are known to spread other
diseases. Howard says: ' While in malaria and tjphoid we have two principal
diseases conmion to the United States which may be conveyed by Insects tli.-
agency of these little creatures In tlie transfer of the disease-germs Is by no
means confined to human beings. In Egj^t and in the Fiji Islands there is
a destructive eye-disease of human beings, the germs of which are carried l.v
the common house-fly. In our Southern States an eye-disease known as pink-
eye is carried by c-ertain very minute flies of the genus Hipj^lates. The so-
called Texas fever of cattle is unquestionably transferred by the conunoi.
cattle-tick, and this was the earliest of the clearly demonstrated cases of the
transfer of disease ty insects. In Africa a similar disease of cattle is tran-

time and innterlnlH than would pay for the best special Impleuieuts, In addition
to which, when the work Is done, 1.^ is neither satisfactory nor effective
There are a great many kinds of Implements for distributing both dry an<i
ll(|ui<I insecticides, many of which are advertised in the agricultural and horti-
cultural paix>r8.

/.„„./M.-Before deciding on what kind to use, it is advisable for one
who has not uscmI these Implements to consult his neighbours wiio have doiu-
so. then write for catalogues to the best known makers; and wh I ij,„^.
make it a general princii.le alwr.ys to procure the most suitable and the lu-st
ot its kind. The difference i.. the Initial cost between a poor, cheap Implement
nnd a tlioroughly good one is small, compared with the subsequent loss and
inconvenience from using a cheap pump or a poor nozzle. Spravlng pumiis
nre made in four sizes: (1) hand pumps, suitable for small gardens, whid,
can be procured at prices ranging from $2 to |5; (2) larger pumj)s mounted
on wheels or suitable for loading on a stone-boat, and consisting of an
ordinary 4()-gallon barrel, with a strong force pump to be worketl l>y hand
which will cost about $20, and will be all that Is required in an orchard of
from fifty to a hundred trees, or in a large garden; (3) knapsack sprayers
which are useful machines, consisting of a tank of about four gallons' capacity'
to be carried on the back, nnd useful when treating outbreaks of cut-worniV
turnip aphis, etc., in field practice; (4) l)ower machines; these are .,f
various kinds, and are for use In large plantations, or for spraying street trees
where great power is required to elevate the spray. These are worked In-
steam, by being geared to the wheels of the vehicle on which the tank is
drawn, or by the escape of carbolic acid gas. The cost of "these will vary
very much according to the make and size of the machines.

Spraying nozzles.— Ot eiiual Importance with a proper force pump in
uistributing liquid poisonous applications Is a suitable nozzle, bv means of
which the liquid can be distributed evenly. The late Professor 'itlley who
did much in the development of spraying machines, said : " The desiderata in
a spraying nozzle are: the ready regulation of the volume to be thrown tli.'
greatest atomising power with the least tendency f. clog, facility of cleansin-
or separation of its component parts, cheapness, simplicity and adjustabilifv
to any angle."

Almost every maker of spraying nozzles has some siwial make whicli he
recommends; hue many kinds now in the market have not the qualities
nec-essary for spraying crops for injurious Insects in the best way. All tln.t
can be said here is that some of these nozzles are far better thtu others. an<l
that great care is necessary In choosing one which will come up to Dr Uileys
requirements, as mentioned above. The experience of others Is a valual.l."
guide m this work; and, both at the Dominion Experimental Farms and -At
the similar Provincial institutions, spraying work Is carried on every vear
which can be witnessed by all who wish to do so, and advice will be fmh
given by the ofllcers in charge.

The operation of "spraying" consists of applying liquids by means of a
force pump and spraying nozzle with such force as to break up the liquid s,.
thoroughly that It falls upon the plants treated as an actual mist or sprav.
Such terms as sprinkling or showering are inaccurate for the operation h.n-

iutemletl. Tnfortunntoly. nui,h of the so-callfHl spiayiiiK. ns usually tarried
out. could more acenrately b<. designated by these terms, which describe a unuh
less careful and less even distribution of llqulils.

Remkdies.

Kemwlles are either Preventive or Active and must be applied in acconl-
nnoe with the circumstances of the case and the habits of the attackluR lns(>cts
Prcrcnttrr rcwcriU-x are either aKricnltural or deterrent. The former of these
••onsist chiefly of such methods as special rotation of crops, liigh culture so as
to stimulate a healthy growth of the crop and keep the land free of weeds and
rubbish; early and late SHMllng. so as to present a crop to its lnse<t enemies
when they appear, in such condition that they cannot injure It. and rotation
of crops, by wliich Insects attracted to a locality by a crop will not have in
that place the same crop to feed upon the following year. Deterrent preventive
renmlies consist of tlie application of mechanical contrivanc. .s. such as bands
of pai)or or tin placed round plants to prevent cutworms getting at them or
the destroying or nmshing f the natural odours of some plants by scattering
amongst tliem substances possessed of a stronger or a disagreeable odour like
gas lime, carbolic acid. etc. Actirv rcmeilicH include such methods as hand-
l.lcklng and the application of various poisonous substances to the plants to
be protected.

.t,-.vP,M7r,«.— The best known of these are Paris green. Arsenate of lead
the Arsenate of lime with sotla. which has lately come into very much more
general use, and Green Arsenoid.

In all of these iiolsons. arsenic is the essential ingredient, and other chem-
icals are mixed with the arsenic for the purpose of preventing it from injuring
vegetation. There are many spraying compounds which ontaln arsenic, some
of which are sold ready-made, and many others are maue at home bv combin-
ing the necessary ingredients.

Pari!, 0»wn.-Undoubteflly tiie best known, and in many respects the
safest poison to use. is Paris green. It has passed through many years of
trial, is well known, has a distinctive colour, and is a definite chemical com-
pound containing 58.65 per cent, of arsenious oxide. 31.29 per cent of copper
oxide, and lO.W per cent, of acetic acid. It is, therefore, an aceto-arsenito
of copper. It is soluble In ammonia. Paris green. If demanded, is
obtained pure in all parts of Canada; but, as there is sometimes' an
adulterated article found in the market, it is wisest always to add an equal
amount, with the Paris green, of freshly slaked lime, whea the free arsenic
will combine with the lime, and it can then be used safely at the rate of one
IKunul of Paris green in IfiO gallons of water on all vegetation, and, for a dry
application, one pound Paris green in 50 pounds flour, land-plaster, slaked
lime, or some other perfectly dry powder.

As a general principle, lime should always be used with Paris green
whenever it is applleil in a liquid insecticide. Paris green Is very heavv and
the particles quickly sink to the bottom of any liquid with which it Is mixed

Lace- Winged Fly (Chrytopa oculata).

When the Ladybirds are great destrojers of scale and aphis, the larvje of
the Lace-wlnged flies rid trees and plants of million of Aphidtr. The flv has
a slender body, with delicate, ganze-llke wings, and Its colour is ?enerallv
gr^n with golden eyes. The eggs are deposited on petllcles and lal.l In tlu'
midst of a group of aphides. The larva Is supplied with sharp mandibles, with
which It attacks the aphis.

disappear. The larva is a footless, eyeless, flattened, transverselv wrinkled
gaily coloured, green and purple maggot, having a very extensile i;odv. whi.h
enables it to reach up and grasp the aphis with its peculiar looking month.
The single egg. dei>osited In a group of aphides, hatches forty-eight hours aftt-r
it is laid, and the h-rva becomes full-grown and transformed into a pupa In fiv
or six days. The reason of this extremely rapid development in the first two
stages, the egg and the larva, is explained when we consider ): .lef Is the
existence of the aphis, and how suddenly its colonies appear and disappear.
When the larva is actively feeding, it destroys dozens of aphides, one after th.
other, and its body changes colour. When filled to repletion the larva falls int..

Wajjs to Kill Ticks.
There are two general plans that may be followed in getting rid oftieks
.'.nd either one will prove suceessful if It is carefully followed out. The first
P an. and the one that every fanner can adopt. Is to use oil. either bv dippi.ig
the stoc-k in mule oil. or by ap-lying the oil by means of a brush or mop the
m-ond plan Is to make use of pasture rotation, that is. to change the stock
from one pasture to another during the summer and fall.

Use of Oil.
("onstructlng a dipping vat is too exjH^nsive for the farmer who mav have

L. O. Howard (Bulletin Xo. 4. r. 8. Depnrtniw.t of Agriculture). Mnj-s-
"Altogether the most satisfMotory way8 of tlghtlng mo^iultoeH are thow whirl,
result m the destruction of the larvie or the aholltlon of their breeding plaivs
In not every locality are these measures feasible, bnt In many places there is
absolutely no necessity for the nios<|ulto annoyance. The three wain i>n"
ventive measures are the draining of breeding places, the introduction of snx.ll
flsh into flshless breeding places, and the treatment of such pools wltl.
kerosene. These are three alternatives, any one of which will be efficacious
and any one of which may be usetl where there are reasons against the trim'
of the others.

Housk-Flies. (llusca domentka) Linn.

Under this general designation tlie several species which infest dwelllni;s
and are not only disagreeable, but from experiments recently coudn.-ted it
has been found that house-flies do carry about on their legs fllth of all kinds
aiid are therefore not only disgusting but probably dissemhmtors of diseas..'
The t-cmmon house-fly {Munca ,lome,tica, Linn.) breeds In nmnure and do.,,-
yard fllth. and it Is therefore of the utmost Importance that cleanliness sl.oul.l
be observetl In and about the premises. Howard says: "There is not mud,
that need be said about reme<lies for house-flies. A careful screening ...
w ndows and doors during the sunmier numt^is. with the supplementarv use .,f
sticky fly-paper, is a methotl known to everyone, and there seems to be llttl.-
hope In the near future of nnuh relief by doing away with the breed'ng pi,u,.s
A single stable in which a horse is kept will supply house-flies for an .vten-l..!
neighbourhood. People living In agricultural communities will probaoly nev.T
be rid of he pest, but In cities with better methods of disposal of garbage. a..,l
with he lessening of the number of horses and horse stables consequent up.,,.
electric street railways and bicycles, and probably horseless carlages, tl„.
time may c.>me. and befc»re very long, when window sc-reens may be discard..!
The prompt gathering of horse ma.uire, whion n.ay be treated with lin.e .„•
kept in a specially prepared pit. would greatly abate the fly nuisance, and dtv
ordinances compelling horse owners to follow some such course are deslrabl.;
Absolute cleanliness, even under existing circumstances, will always result i„
a diminution of the numbers of the house-fly, and, as will be pointed out 1..
other cases In this bulletin, most household Insects are less attracted to th.

flies fn^inently ehwter on the horns to rent. It was from this habit that tiM-.v
Kot their name. 8tatement« that they bore holes Into the hornH are Inamurate.
The only harm done by them Ih due to their very IrrltathiK bites on the Imn1Ii>n
of the aninuils. The eujjs are laid by the females In freshly deiM.slt«I .-..w
dropphiKs. The maKKots liatih In 24 hours and IwH'ome full grown In nlwut a
week : they then burr<»w down a short distanee Into the ground and turn to
brown puparla. from whidi the flies emerge In four or five days. There are
several broo<Is during the Hunuuer, and the last brood or nniggots pnsws the
winter as puparla.

RemnHen

Of the many remedies we have tried, the following have given the greutewt
satisfaction: (1) Smearing the parts most usually bitten with a mixture of
lard, 5 lbs., r.nd pine tar. 1 lb. Two applk-atlons each week when the flies are
very bad. Mix well together and apply to the parts most attacked, brushlnij
the mixture lightly over the tips of the hair. After two or three applications
the treatment has more effec-t than at first. ; (2) Spraying the animals twicv
a week with ordinary kerosene emulsion. (3) Fish oil, 2 quarts, and oil of
tar, 2 oz. ; or flsh oil. 2 quarts, coal oil, 1 pint, and oil of tar. 2 ozs. (4) Goo-I
work may be doue by breaking up the cow droppings In the field. The uiaggutH
can only live In the dung while It is In a moist condition. A boy with a rake
could go over a pasture three times a week and break up all the rresh
droppings and the drying up of these by the sun or the washing away by rnin
would kill all the eggs or maggots, thus locally reducing the numbers verv
much.

Cattle Lice {Trlchodectca scalaris, Ilacmatopinus curynternua, Xitzsch.)
The loss from these disgust) .ud very common parasites of horneil
stock Is far greater than Is genera <ly appreciated. Many animals turned
out in spring in poor condition have been reduced in flesh by the constant
discomfort of being preyed upon by myriads of lice, which might have been
destroyetl by a little attention on the part of those in charge of them On
account of the small size of lice, they are often overlooked until they have
become very numerous and have done a great deal of harm. Lousy animals
win neither rest nor feed well. They are prevented from putting on fle>8h
their growth is stunted, and their meat Is neither so good nor produced so
economically. It Is well known that an animal kept in good condition «n.l
steadily Increasing in weight costs much less to prepare for the market tb:,!,
one whose growth is checked and allowed to get Into poor condition. Li. ,.
cause more loss In stock than Is generally appreciated. This loss is unnect-s-
sary, because all of the common external parasites of live stock can be easily
and cheaply treated. There are two kinds of lice found commonly on cattl.'
the small blue louse or biting ox-louse {Tvichodectes scalaris, NItzsch), and

CHAPTER v.— ANIMAL PESTS.

OopiiEU AWD Grol-nd Squibbels.

These pests are very numerous In some parts of the Upper Countrv. doing
great Injury to crops of all kinds and fruit trees, by gnawing the roots.

The following method Is recommended by the U. 8. Department of Agri-
culture for the extermination of gophers:—

Bisulphide of carbon.~ln most cases bisulphide of carbon Is the simplest
agent for the destruction of gophers. It may be used as follows .-Open the
gopher hole where one of the freshest hills has been thrown out. Pour two
tab espoonfuls of bisulphide on a bunch of cotton rags, tow. waste, or any such
material and push it well down into the hole; then close the opening. The
bisulphide quickly forms a heavy suffocating gas that flows down the hole and
along the galleries. Wherever it overtakes the gopher he Is quickly killed.

^l^'^H , ''^K r " "^''^"y ""°P'* """^ ^"•'y- The only dlfliculty arise,
from the length of the tunnels, which is so great that the animals may be

tunnel and introduce the bisulphide at two or more places

highly Inflammable and explosive; otherwise no danger attends its use.

Others do not soon come In. Their manner of travelling Is so slow that onlj^

not oft '^h ' ::«°derlngs may settle down In a new place, but this does

not often happen. The process of trapping Is perfectly simple, although many
farmers have assured me that pocket gophers can not be caught In traps

unnecegsary if they connect. I depend much upon my Judgment of whctli. r
there is a den or not, to which conclusion many things lead you. such oh ncm
ness of holes, size of holes, lay of the ground, amount of injury to grain ..r
grasses, etc.

In my experiments this spring I likewise tried to determine liow nui. h
would kill the squirrels. To be sure of the mortality, we dug them out. mid
did not rest content with seeing whether the holes remained closed. Tills is
too uncertain, as visitors or strnvs may dig out holes from the outside.

Time to Use.
It can be put out any time In the day, but is best put out near evening, for
two reasons. First, late in the afternoon all of the squirrels have gone int..
their holes, and the execution is more perfect. In the second place, a gn-at
deal of work can be done after supper, when during summer or late spring tin-
evenings are long and darkness does not come till 8:30. It is remarkable
the number of holes two persons, one to handle the spade and the other the
poison, can attend to in two hours. If a field is simply overrun by squirrels,
I would advise using the whole of several days for the principal poisoning!
doing the finishing touches after supper.

Cost of Carbon Bisulphide.

As retailed by druggists, the cost is high, varying from |1.75 to |2.2.'5 per
gallon. In five-gallon cans it can be bought for about ^T-'iO per can, or |1..%()
per gallon. Owing to the danger In handling it, the freight charges are very
high. It Is likewise extremely volatile, as before stated, and there is con-
sequently much waste !n handling it. Could the farmers unite, howover, and
get a carload from the manufacturers direct, probably the price could Jm-
reduced one-haif. I may add in conclusion that, though much more costly
than phosphorus, or perhaps even than strychnine. It is infinitely better, as it
kh> all the squirrels In the holes, while food-poisons kill only a small per cent.
of them.— Idaho Bulletir, No. 11.

Wolves and CovoxBa.

These pests, particularly the latter, are so numerous and cunning tluit
the production of some classes of live stock, such as sheep and poultry, in the
Upiwr Country, is rendered unprofitable, and the almost human sauaeity of
coyotes is such that they are rarely caught in traps or killed l.v ix)ison."jiiMl
the bounty paid for their destruction, viz.. $2. Is not a sufficient in.luiH'm.nt
for anyone to make a business of hunting them. Tlierefore. any nietluMl tlnit
can be suggested by which these wily nnhnnls can he clrcuiuventea will Lc
hailed with the greatest satisfaction.

A Bulletin rectMitly issued by the V. S. Department of ARrionltiiro savs
that success In trapping wolves and coyotes deiH>ii(ls hugely on tlio u.xe of .i
scent that will attract them and keep them tramping inul imwlng until canKlit.
Meat bait alone Is of little use. and often, indml. scares the animals away
Of the nniny scents and combinations tested, the fetid halt has pioyed ni...^t
successful. The following directions for Us preparation and ns«' are given :

Place half a jwund of raw beef or venison In a widenioutluNl hnttle luul
let it stand in a warm place (but not in the sun) for two or six weeks, ,.i-
until it is thoroughly decayed and the odour has become as offensive as

lK>8slbIP. When dw-oinpositioii has reaclied the proiK^r stngo. add „ n„art of
sporni oil or any liquid aniu.al oil. Lanl may Ik- use*!, but pralrlo-doR <,il is
betfer Ihon add oue ounce of tincture of Siberian nnisk. or T..n.,uin n.usic
If this cannot lie procured, use in its place one oun.-e of drv. pulveris.^1
castoreuni (l>eaver castor), or one ounce of the connnon n.usk sold for iht-
funiery. Mix well and bottle stnurely until used.

After setting the trap, apply tlie s^rnt with a sticlc or straw or bv po.irlng
from the bottle to the grass, wetnls. or ground on the side of the tra,", opposite
that from which the wolf wouhl naturally approach. Never put sc-ent on the
trai> as the first Impulse of the wolf, after snuHing the scent, is to roll on it

This bait is very attractive also to cattle and horst's. wliich are sure to
tramp over and paw out the traps if set where thev can get at tliem

Tlie Bulletin also recommends the following meth.Hl of i)oi.K..ning wolves
and coyotes: — *, "wmn

No pois(m has yet proved .so eiTwtlve as pure sulj>hnte of strvchnine
provldeil the proper dose Is uswl. The most effective dose is 4 grains for
wolves and 2 grains for coyotes. The comn.on 3-grain gelatin capusules sold
by druggists will hold, if well filled. 4 grains of stry.lu.ine. and are better
than the larger capsules. The regular 2-grain capsules should be used for
<1.yetes. The capsules should be filled, securely capped, and every tra.Hj of
the Inten.sely bitter drug wiiH^i from the outside.

Eadi capsule sliould bo lnserte<l in a piece of lieef ^uet the size of a
walnut an<l the cavity securely closed to kivj) out tlie moisture. Lean meat
should not be used, as the juic>e smm dissolves the gelatin of tlie capsule ThP
neeessary number of poisoned baits may be prepared and carried in a tin can
or pall Ihey should never be handled ex,t«pt with gloved -uTs or forceps.
The baits may be dropped from horsebaclv along a sceiite.1 d.a«' line made by
.ragging an old bone or piece of hide well saturated witli tlie fetid sctM./ or
tliey may Ih^ placed around or partly under any carcass on which tiie wolves or
n.yotc's are feeding or along trails which they are In the habit of following

Gelatin capsules quiclvly dissolve in the jui.es of tlie stomach. Strvch-
nine taken on an empty stomach sometimes kills in a very few uUnut..s.'but
on a full stomach Its action is much slower, and the auinial may have time to
travel a considerable distance.

Further Itistritction,^.
^ircular No. ra, issued by the Bureau of tlie Biological Survev. Washlng-
on. D. C.. gives the results obtained during ]J)07. in the way of wolf destruc-
tion. The methods of capturing wolves in common use are thn^-(l)
rapping. (2) use of scents, and CI) pols<mlng. For trapping, the best'xo 4
<><>"b e-spring trap should be uschI with a heavy stone as « ,lrag When
possible, the trap should be p:nced between two tufts of grass or weeds, so that
i can be readily approaduHl from one side only. The trap, stone and chain
s hou d be buried on a run-way. S..e„t is use.l to attract wolves to the vicinity
of the trap. Fetid bait is ma.le by placing half a pound of raw iMM-f or
venison in a wide-mouthed bottle and letting it stand in a warm place for
from wo to six weeks. When ...mpletely decomposwl. add a quart of any

service berry nnd hawthorn nre frequently diseased, but not to such nn extent
as the flrst-nanie<l trees. There is a diffen>nce in the susc»>ptiblllty of varieties
Thus, among iH'jirs. flapp's Favourite, Flemish Beauty, and Bartlett are ni..n-
liable to the disease than KelfTer and Duchess, and amongst apples, the (nil.
varieties are the least resistant.

Climatic conditions influence the disease; warm, moist weather wiih
much rain favour It, whilst bright, dry, sunny weather tends to check it.

High cultivation, rich soil, heavy manuring. fret« use of fertilisers. Iicax.v
pruning, or any other treatment which has a tendency to Induce new and
succulent growth, favours the disease, as the bacteria grow with far greater
rapidity and iK-netrate more quIcKly from cell to cell when the tissues are
gorged with sap. Insects are more partial to young sucrulent shoots .iihI
leaves, and the bites and punctures of such Insects whose mouth parts may l.e
contaminated with jK'ar blight germs often serve to Infect the tree.

It Is thus manifest that healthy, thrifty, vigorous, well fed and wel!
cultlvatetl tnt's are more liahlc to the disease than others, and henw tiie
severity of nn attack of fire blight may be lessened by conditions wiii<li are
under the control of the grower.

Treatment.
The treatment of fire blight is of two kinds— that which is design»>d to
put the tree in a condition to withstand the attack of the blight microbe, ami
these methods which aim at the extermination of the casual bacterium.
Unfortunately, all methods which nre used for hindering the attack of the
microbe consist of restraining the full development of the tree, and hence any
such system of procedure should not be followed unless an orchard Is very
badly atackeil.

High cultivation, with pruning and the other conditions already mentioned
as predlsitosing trees to blight, should be nvolded, but the trees should 1m-
allowtHl to rir)en the wo<k1, and in order to do this the fruit-grower must use
any method which will check the amount of moisture in the soil— for Instance,
by the growth of a clover crop.

Tlie Are blight organism cannot be exterminated by spraying, as the
microbe lives in the tissues iMMieath the outer bark, and it is Imimsslble n.
reach it with any spraying solution, for, unless the bacteria come into contaet
with the germicide, spraying is Ineffectual.

There is. therefore, but one remedy, to cut out nnd burn the aff«HttMl
parts of the trw. It is very necessary when cutting out a diseased l)raneli
or twig to cut well below the dlscoloure<l portion, as the bacteria are In nio.st
cases far below the di.scf)loured portion, the discolouration not being phkIik..!
immediately uiwn the appearance of a few bacteria, so that if only the dis-
coloured portion were cut off numbers of bacteria would still be left in the
stump, and these would continue to multiply, and the disease would soon he
evident again.

Cutting of affected parts may be done at any time in the winter ami
spring, but It is not advisnlde to cut in the growing season, as fresh cases may
be ctmstantly (Xturrlng. and these, owing to lack of suHlclent development,
would not be seen.

81

The best time for tuttliiK out afrecte<l hrumhes Is townnls the fall, or
when the trees have stopjH>d foriniriK new wofHl. when most of the blight has
develor)ed. and when the contrast between the distolouriHl leaves and branehes
and healthy tissues Is easily seen,

Tr«-<.M should be carefully Insiiectf'd for blight dnrlng the winter and In
spring before the blossoms eonie «»ut. In order to destroy any aflTeeted parts
that may have been missetl at pvivlous lnsi)ection.

All trees of the pome family in the vicinity should be examlnwl as well,
as tliese, if bllghteti, may serve to re-infwt an orcliard which has been care-
fully treated.

In cases where the l»ark of the trunk is aflfe<te«l, it can be cut out and
the wound covereii with a lead or oil paint. The cut surface of the branches
()ver one-half inch in diameter should also be painted.—/'. C. Harrimni.
Ontario Bulletin, A'o. 13G.

Wlien a tree blights, remove and burn at o\m\ outside the orchard, every
trace of diseased wo<k1. Saw off the smaller Itranches about a foot below the
least sign of disease, and dig out the spots on the trunk and larger limbs.
<-utting deep enough to remove all discolouration. The knife and saw used in
pruning should always be (Hslnfected with carl)ollc add before leaving eacii
tree, to avoid infecting the freshly-cut healthy wootl of the next tree. The
exposed surfaces should be at once painted to exclude germs that may be
floating In the air.— 0/ti;o» Bull. 27.

Leaf Blight of Pears {Entomonporium maculatum. Lev.).

The fungus causing this disease attacks the leaves and fruit of the i)ear
and (piince. On the leaves It provinces small rounded sjiots of a brownish-red
colour. On the fruit the spots soon lose their n?«ldlsh colour, liwoniing much
darker, while tlie surface sometimes becomes cracked In severe cases as with
the si'ab. In tlie centre of the diseased siwts small pimples may be seen, due
to the formation of si)ores beneath the epidermis. Later these cracks o|»en.
allowing the spores to escai»e.

The spores themselves are very i)eculiar, each being c«»miK)8ed of two
large an<l several small cells, united and possessing several bristle-like
pro(<'88«'s giving them an api»earanv-e suggesting some kind of an insect. It is
sometimes especially bad on nursery stcK-k in the row.

It is «iulte readily controlled by the Bordeaux mixture, about three appli-
cations serving to keep the foliage and fruit free from the disease.— J//e/«i»aM
Ii:il!rt;i: .V.o. 25.

The Shot-hole fungus (('iiUndrosporium padi. K.) penetrates the entire
leaf, but congregates in spots to prcMluce siK)res. Here the tissue dies, be<-omes
brittle and soon breaks away, riddling the leaves, whlcii turn yellow and fall
lirematurely.

Remedy.
Spray with Bordeaux mixture or annuonlacal copper carbonate about
June Ist. and every tlirw weeks thereafter. If the disease is had.— Ornjon

The mycelium or plant body of the fungus remains dormant during the
w nter In the dried or mummied plums which are left on the trees Infected
with the disease, or on the ground beneath them, and when warm weather
comes the following season will pro<luc-e an abundant crop of sr)ore8 to start
Infection afresh.

In dealing with this disease. It will be easily seen that the most successful
T,TZT T "^""'•"y ^ «' '^ preventive nature. It Is usually first
noticed m the season on cherries. esiKvlally on soft varieties which burst their
skins after a rainstorm, such as the Governor Wood, and, undoubtedly, Infected
fruits wh ch are left to dry up on these trees are a fertile source of Infection
to plums later In the season. Great care should be taken to gather and burn
these, and also the first Infected mouldy fruit noticed on plum trees In
orchards which have been Infected this season, the first thing to be done Is
to pick off. as soon as possible In the fall, all dried up or mummied fruit which
may have been left on the trees, then with a fln^toothed garden rake gather
ogether all fruit that may have fallen on the ground, together with fallen
leaves and trash, and burn up all these sources of Infection ; after whicli the
trees should be thoroughly sprayed with Bordeaux mixture of double strength
viz.: 8 pounds sulphate of copier, 8 i)ound8 lime, and 50 gallons of water-
the ground beneath the trees should also be well sprayed with the mixture
This should be followed by a thorough spraying with Xo. 1 Mixture (lime
salt and sulphur spray), during the dormant season, both of the trees and of
the ground beneath them.

In the spring, the spraying of the trees with Bordeaux mixture of the
ordinary strength should be commenced as soon as growth starts, and at least
two sprayings given after the blossoms have fallen.

If there is reason to expect an attack of the disease after the fruit has
attained Its size and before ripening. Spray No. 10-the Carbonate of Copper
foT/r, ?^ be carefully used, as at this stage the fruit Is particularly liable
to be infected. Cherry trees should be carefully sprayed with double strength
Bordeaux mixture as recommended for plum trees, while the trees are dor-
mant and in the spring the trees should be sprayed with Bordeaux mixture
of ordinary strength when growth commences, and again after the fruit has
rormed.

-t HH u^y' " *^ '*"*^ by Professor Cordley. "that now the disease Is well-
established, any prune or cherry grower who falls to employ preventive
measures against brown rot deliberately takes the chance of losing a large
proportion of his crop, even though such loss may occur every year." and this
statement applies with the same force In Lower British Columbia

with it and It has been amply demonstrated that this season almost the entire
crop of some badly infected orchards was unfit for shipment. A goc^ dealTf
he loss experienced this year was due to the development of the dIseaL
in hepackages en route to market, the temin-rature inside cars filled with
fruit being high enough, and sufficient moisture present to fun,i«h fav.Hirable
conditions for the spread of the rut to a large portion of the shipment

Symptoms.

The first indication of this disease Is to be seen on ihe leaf In the shape
Of a s Ight -Hluctlon in the Intensity of the colouring-matter «.f the leaf. This
!• rapldii »ilowed by the appearand, of small brownish blotches, commencing
generally at the edge of the leaf. These spots soon Increase In sl7,e and the
tissues die. turning dark brown or nearly black. In dry weather these
patches do not Incnasr much, but In humid weather they spread over the
eaves with Immense rapidity. After destroying the leaves, the disease
travels down the haulms, and in severe cases the whole of the aerial mirtlon
of the potato plant may within u few hours become a blackish mass of rotten
plant-d^brls. which emits a characteristic and unpleasant odour. If the under-
surface of the leaves be examined with a iKJcket-lens. there will generally be
seen around the margin of each 8i)ot a more or less distinct border of whitish
mould, looking somewhat as If fine flour had been sprinkled on the leaves
This white mould Is the fruiting portion of the fungus causing the disease'
and as myriads of spores are quickly formed on each leaf, it Is easy to
understand how It can be spread so rapidly.

This potato-disease is practically wholly propagated and carried on from
season to season In the tubers themselves. It is. therefore, of the first
importance that none but perfectly sound potatoes should be used for seed.

The appearance of diseased tubers is very characteristic. Numerous
sunken, dead, brown patches are developed on the surface of the tubers
These may remain firm and hard for some time, but generally thev become
soft, and the wholo tuber rapidly rots. This rot is accompanied with'a partic-
ularly foetid odour, quite distinct from the rots caused by bacteria, fusarium.
etc.— A'eic Zealand, ISth Report. «iiuuj,

Seed potatoes should be stored in a perfectly dry and well-ventilated shed
They should be examined at intervals, and any tubers showing signs of disease
should be at once destroyed.

The dipping of seed potatoes In Bordeaux mixture, using the 4-4-40 form-
ula or. If the skin Is well hardened, the 6-4-40 formula. Is to be recommended
A large barrel should be used, and the potatoes placed in a basket made of
wire-netting, or some such material, and the potatoes totally Immersed for a
few minutes, then lay them out In a warm place to dry before storing. It
must be remembered that this dipping kills only the spores and those portions
of the fungus that are on the surface of the potato, and Is quite ineffectual In
destroying the part which winters In the tissues of the tubers themselves

Early Blight, or Potato Leaf-Clrl {MaciOHporiitm solani).

This Is caused by a fungus which attacks the foliage. It Hrst appears
on the older leaves In the form of small brown or grayish-brown spots, which
gradually spread and Join, so that soon a considerable area is Involved, the
affected parts becoming curled, hard and brittle, while the remainder
frequently assumes an unhealtliy yellowish colour. On the apjiearance of the
disease the tul)ers cease to grow. Usually in about three we<'ks most of the
leaves are dead; the stems remain green for some time longer, and then
gradually perish. The tubers, being undeveloped and unripe, turn soft atid
will not keep. It has been proverl by extensive exiteriments, both in Europe
and America, that spraying with Bordeaux mixture will not only prever; or
keep down fungous diseases, but will so increase the yield as to more than pay
the extra expense Incurred. Great care must, however, be taken in mixing
and applying fungicides and Insecticides.

The Macrosporiiim must not be mistaken for tlie extremely destructive
"potato-rot," so much dreaded in older countries. There is no doubt tliat it
has been so mistaken, both in England and America, and this mistake has
given rise to reports that "potato-rot" (Phytophthora infcstam) had broken
out in various localities, when it was only Macrosporiiim, which, serious as it
may be, is not nearly so bad as Phytophthora.

Treatment.

As the spores of the potato leaf-curl live through the winter on the dead
haulms and leaves of affected plants, it naturally follows that to prevent a
recurrence of the disease It Is essential to carefully burn all tops, etc.. that
have in the previous season shown the least signs of infection. This burning
should be done as soon after the potatoes are harvesteil as possible, as delays
are always dangerous.

Potato Bactebiosis (Bacillus solanacearum) .

The first sign of disease Is disclosed by the yellow colouration and prema-
ture wilting of the foliage. Sometimes only a few isolated plants are
attacked, at other times whole rows may become diseased. At a later stage
the veins of the leaves take on a darker hue than the rest of the foliage, which
then rapidly ili.scolours and dies.

If a diseased haulm is cut across it will be seen that the woody cylinder
shows a brown discolouration, and the vessels are filled with bacteria, which
gradually ooze out from the cut surface in dirty-coloured drops. In cases of
severe attack the tubers become affected early and rapidly rot.

Preventive Means.

It has been definitely proved that this disease Is transmitted from field to
field through the agency of leaf-eating insects; In the United States the
Colorado beetle being esi)ecially active In spreading this bacterial blight. In
consequence of this, it follows that In districts where bacteriosis is knr)wn to
exist all leaf-eating Insects should be kept In check. For this purpose the
addition of 4 oz. of Paris green to every 40 gallons of Bordeaux mixture will
be found an excellent chock.

Dry-rot of Potatoks {Funnriiim ojjiKporum).

The (lisoaso to which the iiaiu.' " dry-rot " lias Ik.-ii givni is cans...! by
several diffm-iit fungi, hut the one whlefi .lr,es the main amount of <lamaK<' is
known as Fumihiun ojnjKimum. a fimgns vi-ry Hoselv allied to the sleepy-
.lisease fungus of tomatoes. The I'nxariHin Is fairly prevalent, hut is generaliy
not noticMl until a oonshh'ral.le time after the tubers have b.n-n store<i
although the disease is contracted while tlie <rop is growing in the field The
foliage of diseased plants geui-rally wilts, but as this does not (n-cur till the
tubers are nearly lull-grown, very little notice is taken.

The disease enters the tubers at the stem -nd and graduailv spreads
through them. f.)llowing the course of the vascuar bundles, and thus shows
up a discoloured ring when cut across. At first sight one is reminded of
p..tato-bacteriosis, but it can at onci> 1m. distinguished, owing to the absence of
any watt-ry matter oozing out from the dl.s«olr.ured ring. The tubers gradually
shrink and the skin bm.mes wrinkled, while the whole interior becomes trans-
formed into a more or less hard, crumbling mass of a grav colour. The fruit-
uig j.art of the fungus iijipears on the surface of the tubcTs as specks of white
mould, on the delicate filaments of which are produced the characterlsti."
sickle-shaped spores, which are divide.l into four by transverse septa. Sound
potatoes can readily contract the disease through coming in contact with
diseascHl ones. Thus the loss that may be sustained through the storing of
healthy and diseased tubers together can easily be imagined.

Treatment.
As this fungus enters the plant b..low the ground, and may gain access
during any part of the season, it is dmicuit to cope with; neverthele.ss the
following measures will be found fairly satisfactory :—

1. (July sound tubers should l)e used for seed. It is equally important not
to plant iKjtatoes on laud where the .lisease has recently appeared, for this
fungus can live in the soil for a considerable time, probably for sev.Tal years
.Such infected land should be used for otiier .rop.s. such as cereals or grasses'

2. Collect and burn all badly-diseased tubers and store susi)e<-ted ones in
a cool, dry place, where the temi.erature remains about 40 Fahr

3. If it is found impracticable to store in a cool place, the tubers should be
sold and eaten as soon after harvesting as jK.ssibie. There is no danger in
eating partly affected potatoes, as b<.iling kills the fungus; ami even if tlicy
were eaf..n raw the fungus cannot harm human being.s, as it cannot grow at
onlinary blood tenijierature.

4. Nitrogenous manures have been sliown to increase the virulence of thia
disease, lience they should be avoided as far as i.ossible.

5. Never throw diseased tubers on the manure-heap; this is one of the
most fruitful .sources of the spread of nearly all fungus diseases

(}. Spraying with Bordeaux mixture makes the plants much more healthy
than they would otherwise be, and helps then, to resist this disease

Mint Disease (Puccinia mcntliw).

Specimens of a disease which killed off most of the garden mint in
Victoria were submitted to Dr. Fletcher, who reported on It as follows :—

"The trouble with the mint seems to be a sfwcies of rust, allied to grain
rust, and known as Pucvinia nicnthw, the uredo form being jiresent jit the
time you plucked the si)ecimens submitted. Curiously enough. I f..iiii.|
associated with this fungus very small red maggots, very nuich like those nf
the common wheat midge, several of these larvie being in the package that
you sent me. I find this or a similar kind of maggot feeding ou the sp..r.s
of grain rust, and also I have recently found what appears to be the saint-
thing feeding on the spores of a rust attacking the leaves of the ilay n]>\<U:
These maggots devour the spores, but I fear can do but little in controlljn;;
the rust. As you know, we are almost helpless In controlling rust, and I
regret that I am not able to suggest a remedy in your case. Its abundance
on mint with you may be due to meteorological conditions, though it nnist be
present in more or less abundance every year."

Diseased Grass {Phi/sarum ctnereum).

A si)eclmen of diseased grass from the lawn of Mr. Justice Martin was
submitted to the U. S. Department of Agriculture, and tlie following n-port
was received from A. F. Woods. Tathologist: —

"The material was .so broken before it reached us that only a small
portion of the organism could be observed, which Is by no means sutticient
for a specific determination. Similar material from lawns is very frequently
sent us, which, probably without exception, lias proved to be Phiisannn
cinereup', which occurs very commonly on richly manured ground. MiixotHii-
cetcs, also called Miicctozoa, are peculiar organisms possessing both anlm.-il
and vegetable characteristics; hence they have been claimed by both zoolo-
gists and botanists, probably not belonging rightly to either, although their
descriptions are generally included in worlcs of systematic crji)toganii.'
botany. The life history of the Mii.iom]icctcs comprises a motile stage in
which the Plasmodium streams or spreads over a surface of perhaps even
.several sciuare feet, and ascending substances, as the blades of gra.^s, are com-
pletely covered with the fruit called .sporangia. As far as I know, tlif
Ml/xomycctcs, with extenml siwrangia, have never been reported as of any
economical Importance. Changes in temperature and humidity, unfavourable
to the species cu grass, may have already caused its disappearance, and it is
doubtful if experiments with fungicides would be profitable."

Smi.t is Grai.x.
\yiiat the ,Siniit in.

Wheat smut Is ciinscd by a small i»laiit \vlii<li st«'!ils Its HmmI from tlu>
wheat j.laiit. The siiint plants are <listrlh\ited l.y the thie. Mack iiuw.lerv
grniiis of smut which cliiitf to the s<'e(l wheat. Kven when tlie wheat
apiK'ars to he clean, they may he itfesent In the grooves in the side of the
grain or in the tnft of lialrs at one end. When the farnuT plants tlie wheat
he also j>lants the snnjt. As the smutted l<eni<-l ;:<m'h into th.« ground it
carries witii it .sev«Tai grains of smut. After heing planfe.1, tlie wlieat grait,
grows and brings fortli a small plant. So also th»! snuit plant p-rmlnates and
sends out a fine tliread-lik.' j.lant so small that it cannot b«' seen with tlie
unaided eye. Tlie smut plai soon prcnluces small thread.s. wlilch i.eiH"trat..
into the small wheat i.lant tlin.ugh Its w.ft and delicate .sUHi. After a few
day.s, lio\vev«'r. at about the time that the wheat unrolls Its first leaf, its skin
gets t(K. liard to be itenetrated by the smut, so tliat if the wheat has escaped
thus far it is no longer in any danger from the smut.

Jf the smut has penetrated the wheat skin <luring its danger period it
contiiuies to grow in the wlu-at plant up through the stem. Alx.ut the tinu
that the wheat plant niak«-s its seeds the smut sends its thread into tlie wheat
kernel. As fast as fowl is stored up for the young wheat j.lant, the smut
steals it and replaces it with its smut grains.

In the covered or stinking smut of wlieat only the Inside of the kernel is
removed by the smut and a sliell is left around it, but in the loo.se snuit.s as
for example the loose smut of oats, the whole kernel is destroyed and the
spores are left exposed to be blown about by the wind.

The wheat kernels which have been smutted are broken in handling or
in threshing, and the smut grains are thus scattered on to new wheat and
are ready for the next year's planting. Very evidently, the only way in which
this disease can be reactuHl and the smut plants killed is bv treating tlie seed
wheat with something wliich will kill the smut grains, but whldi will not
injure the wheat.

name Vstilago is derived from the Latin word ustus, burnt, and the specific
name carbo means charcoal. Both names refer to the appearance of the spore

licmciUcs. — Wheat.
For wheat, probably nothing is more effective than the common bluestone
treatment, using one pound of bluestone dissolved In a pail of water for eight
or ten bushels of wheat. The solution should be sprinkled over the seed and
the grain shovelled over several times, to Insure that every kernel of grain
is moistened with the solution. It is not always convenient to have boiling
water to dissolve the bluestone. and It will not dissolve in cold water unless
It be placed In a sack and suspended In water. Just below the surface when It
is claimed It will dissolve In a few hours. The amount of bluestone necessary
to make a barrel of pickle can thus be dissolved readily by suspending It In
an old sack across the top of the barrel, Just so that all the bluestone is
submerged under water.

Formalin Treatment.
Formalin Is a 40 per cent, solution of a gas In water. As obtained at the
drug-store it has the appearance of water, but has n characteristic odour
It Is poisonous m the strong solution in which It is bought and sold, but not
in the weak solution in which it is used on the grain. About one pound of
formalin is necessary to each 40 or 50 bushels of grain to be treated. One
should be able to purchase it at the drug-store for about 45 to 60 cents per
pound, buying it in pound lots or larger. Mix it with water at the rate of
one pound of formalin to 60 gallons of water. Make a wooden trough about
the size and style of a watering trough and a little wider than a shovel
Partly All this trough with the formalin solution. Pour the wheat slowly from
the sacks into the trough, so that the grains will separate and the smut balls
and wild oats will float.. Skim these off. Let the wheat remain In the trough
and see that it continues to be covered with tlie formalin solution for at
least one and a half or, better, two hours; at the end of this time, shovel it
out on to a bam floor which has been cleaned with boiling water, or shovel it
Into a canvas sheet which has been cleaned in the same way and is supported
between posts. If the weather be favourable for drying the wheat, it may at
once be put into the sacks and dried in them. Use only clean sacks, that is new
sacks, or those which have been cleaned in boiling water. Soaking Little
Club Wheat (which is the softest wheat raised in Eastern W.nshingtosi) for
one and a half to two hours will not appreciably soften it. At the end of that
time it can scarcely be dented by the finger nail.

h.fested fruit trees, in the winter or very early spring, before growth starts

During the summer months, a badly infested leaf has Its un.ler side completelv

covemi with a dense web. under which are eggs and mites in all stages of

deve opmen . and it Is dltBcult to reach the pests with ordinary spraying

In C allfornla. however, where they are very troublesome pests, the follow-

ng me ho<ls are in use in spring and early summer as soon as th" eggs are

bellous or other appliance, after they have been wetttMl by a spraying. Some
growers use a spraying ndxture n.nde In this way: Take 20 L.'of sulph r
and n.ix to a paste with com water In a barrel ; then add t.> this wet s Ip ,;
10 lbs. of caustic scxla. 98 per cent., when it will boll up like lime si kl g
bave ready 20 gallons of water to add to it as it boils, to prevent b r n 1 fg

This forms n stock solution. nn.l when ready to sprny put 40* gallons of water
In another barrel, and take half a gallon of the stock solution and add to If
strain, and apply with the spray pump, taking care to wet the under sides of
the leaves.

At Chllllwack, a strong hot solution of whaio-oil soap, applied with hand
sprayers, has given gocxl results against the red mltc' of the hop, but very care-
ful work is required to reach the pests, and it must be done soon after the
mites are hatched out.

7?cmcd/('*.— Various preparations of sulphur and soap have been recom-
mended, used separately or together, mixed with water, and applied to the
bushes with a syringe. Plain soap and water, or water alone, freely applied
Is regarded by some as efficient, as the Insect Is known to thrive besi in a dry
atmosphere. In applying any liquid. It Is necessary to wet the under side of
the leaves In order to make the application effectual, since. If applied to the
upper surface only, the mites would .emaln uninjured beneath.— TV. Saunders.

Apple Aphis (Aphis mali).

(Fio 2r).) Greatly enlarged

106

The eggs of the apple aphis are deposited In the fall, usually on tho
extremities of the new growth, or around the buds. Two thorough annii
cations of the No. 1 spray, according to the directions given, or of the lye an.l
soap wash (No. 15), will destroy the eggs, and this Is by far the best lueth.Hl
of dealing with t),.- pest In the first Instance. In a natural way the eggs hat.l.
out just when growth commences In the spring, and the leaves of Infested trets
soon become curled and roll up, making It very difficult *o reach the lusivt
with any spraying mixture.

They multiply at an enormous rate, those first hatched giving birth to
living young which In their turn reproduce In the same way, and so on f.,r
several generations, so that as fast as new leaves expand, they are attacked if
the weather conditions are favourable to the aphides.

For summer spraying, any one of sprays Xos. 2, 6 or 7 will, if used as
directed In the earlier stages of attack, prove effective; two sprayings are
usually required, and are better given with only a short Interval between them
not more than three days. Care should be observed to make the spraylng,i
very thorough, as the washes kill only by actual contact with the Insects.

During the summer winged broods of the pests are born ; these should bo
looked out for, and prevente<^ from establishing themselves by a timely use of
one of the spraying ml" ires referred to.

Blac: Jhebbt Aphis {Myzus cerasi)
Is very Injurious to the new growth, especially on young trees. It multiplies at
an enormous rate In a similar manner to the last-mentioned pest. Badlv
Infested trees are often a source of attraction for swarms of files and wasps
which feed upon the sweet exudation from the bodies of the aphides.

I'rompt and thorough sprn.Mng In the early stage of the attack Is necessarv
to deal with this pest effectively. It Is more resistant to the action of sprav.
than the green aphis, but the same remedies should be used, and better results
w follow f the spraying mixture Is made as hot as the leaves of the trees
will bear without Injury.

CuBBANT Aphis (Myzus ribis).

is yellowish In colour and Is found on the under sides of the leaves of currant
bushes, which become curled, blistered and reddish In colour. They migrate
during the summer, but return later on, and their eggs are deposited on the
stems, especially around the buds.

Spray with the Is'o. 1 mixture to destroy the eggs In the winter months, and
.nT^f «f sprays Nos. 2. 6 or 7 in the growing sea.son. directing the .sprav
so that the under sides of the leaves are reached. It Is most Important that
the work should be done early In the season before the insects become t...
numerous, and tlie leaves roll up so that sprays cannot reach them.

Wheat Midoe (Diplonis tritlci, Kirbv).

A«ocA\— When wheat Is in blossom In the month of June, minute yellow
midges with black eyes may be found, particularly t.)wards evening. 'flyin-
over the fields and la.vlng eggs In the florets of the ears of wheat. Th.-se e-'s
m about a week hatch Into small reddish-orange maggots, which s.)nietimcs
to the number of ten or twelve He Inside the chaff and suck the juices from
the swelling kernel. When mature, they leave the ears of wheat and ik-m.-
trate about an inch beneath the surface of the ground, where they spin tiny
cocoons. Inside which they remain normally until the following spring wh.ii
the perfect midges emerge. Under si)eclal circumstanc-es. however, sonic of
the flies appear In late summer and lay their eggs upon volunteer wheat ..r
the young fall wheat.

It Is many years since the Wheat Midge, which Is generally known hv
farmers and millers as " the weevil," has been the cause of much loss in th'.-
wheat crop of the Dominion. Fifteen years ago the losses were enormous-
but, Just when it seemed at Its worst, it suddenly dlsapi>eared entirelv an.l
since tb.t time has not been the cause of widespread injury. There have
been occasional outbreaks, as In the Niagara district in 1898, and last vear
In the fertile Chllllwack district of the Eraser River Valley. B. C. where it
was estimated that In some fields fully half the crop was destroyed.

Gbain Aphis (Nectarophora gramrla. Am\; etc.).

.4«acfr.-Green. yellow, reildlsh or dark-co ared plant-lice, sometimes
occurring In large numbers upon the heads and eaves of wneat. oats barley
and rye. weakening the plants and preventing the kernels from filling 'as well
as they should. These plant-Uce generally dlsapi^ear suddenly just as the
grain is beginning to change colour, being as a rule destrove«l bv their many
parasitic and predaceous enemies before much harm Is done to the crop

It is probable that there are two or three species of plant-lice which attack
grain as described above. It is known that some broods of several species
feed upon one class of plants during part of their lives and upon grasses of
various kinds at other periods of their existenw^. Some of these as the
apple aphis occasionally may be found upon the small grains and 'grasses
It Is convenient to speak of all these kinds occurring uiK,n grain crops under
the name of grain aphis.

I?cmcrf;/.— So far. no treatment has Ih^u discovered for controlling plant-
lice when on grain crops; but. fortunately, they seldom affect the output to
any considerable extent. The apple aphis {aphis mail. Fab.) frequently
develops into a serious enemy of young fall wheat; and. as this Insect passes
the winter as an egg upon the twigs of apple trees, the regular spraying of
apple orchards with kerosene emulsion (Remedy 2) would not only clear
those trees of a serious enemy, but also to a large measure protect the fall
wheat of the following season. A similar alternation of generations takes
place in the case of the hop aphis, which passes the winter In the egg state
on plum trees, from which a winged brood of the plant-llce the following
summer migrates back again to their summer quarters on the hop. Spraying
the plum trees during the winter reduces largely the occurrcce of hop aphis
later In the jear. — Fletcher. '

n'HiiItH. ami Is actually more nttrac-tlve than khh-i. veuatlon. Th.- mixtnr..

the proj-ortloii of 1 ,.„nnd to 50 pound* of bran In n.aklnu tin's n.ixtnn
the most convenient method Is to damiK-n a huuiII (pmntltv with th.- sw.vi
ened water (a few .mnees of sn«ar In a pall of water), and then add ni.„v
dry bran, until the whole is almost dry again. If the Paris green Is a.l.l,..|
to the bran without dampening. It sinks with rem-.rkable rapidity to tii,.
bottom, even In this dry ndxture, when It Is stirred.

If It Is desired to use the poison as a wet aj.pllcatlon. more water .an l...
adde<I until It Is of about the same consistency as porridge, but If It is t.. l...
ustHl dry. dry bran must Ik- stirred In until the mixture will run thr..ugli tl...
lingers easily. The poison may then be applied to the land, elth.-r aroinnl
or betwe<.n the plants to be protected, or a row of It may be run dose t.. tl...
drills of crops planted in that manner.

This mixture Is extremely attractive to cut-worms, being pref.'rred t„
plants In all the instances which have come under mv notice It f.k.s
about ten pounds of this ndxture to an ,u>rt of iwtatoe.^^ as ordinarilv plant.M
Paris green being a deadly poison, care should be exercised to keep It out of
the reach of children and domestic animals.

Salt in lieu of Sugar.

Walter W. Froggatt. F. L. S., Government F^ntomologlst of New S.Mitli
Wales, m an article entitled "A Fight with Climbing Cut-Worms (LcNnnua
uminttwta)." says: "The bran was brought up In bags, weighed, and 1 poun.l
of Paris green added to every 10 pounds of bran. The bran, after beiu'
welghe<l, was poured out on large bag sheets, the Paris green scatt.'r.M'l
through It, and two men with long-handled shovels mlxetl It up thoroughlv
AVhen the whole was of a delicate gretm tint, water was added from a ho-s-
head, In which about half a bucket of salt had been put, so that It just ha.l a
salty taste. The first lot of poisoned bait used before 1 arrived had been
flavoured in a similar manner with augar. This had a hardening effect up.,n
any bait remaining over till the next day, so I substituted salt, with very
good results; the caterpillars seemed to eat It more readilv, and the fotKl
remained moist at night."

Hand picking or digging up the cut-worms whenever a plant Is seen to
be cut off should, of course, always be practised.

Traps made of disused' tins, short sections of drain pipes and similar
things sunk In the ground and covered over with boards, allowing sufficient
room all round for the caterpillars to creep under, will capture number., of
the pests. Fven ditches with steep, smooth sides, prevent a great many from
getting from one part of the field to another, and when the ditch has wat.r
in It it is quite effectual.

Preventive Measures.
Preventive measures consist of: Clean culture, by which all ve-etatio,,
is removed upon which the young caterpillars could feed in the autumn or
which would attract the moth- to lay their eggs.

(Fio. 33.)
This inswt passes the winter In the pupa state umler ground ; the rti..«
the progenitors of the mischievous brood of slugs. ai.iH-arlng on the wh.«
about the third week In May until the middle of June. The fly is of a ^'l.,ss-
bla(-k colour, with four transparent wings, the front pair being crossed by a
dusky eloud; the veins are brownish and the legs dull yellow, with bin. k
th ghs, except the hind pair, which are black at both extremities, an.l .lull
yellow in the middle. The female fly is more than one-fifth of an inch Uma-
the male is somewhat smaller. When the trees on which these flies are ,n
work are Jarretl or shaken, or if the flies are otherwise disturbed, they fall to
the ground, where, folding their antenmo under their bodies and bending the
head forward and under, they remain for a time motionless.

The female of this species begins to deixmlt her eggs early In June: thev
are placed singly within little semi-circular incisions through the skin of the
leaf, sometimes on the under side and sometimes on the upi^er. In alM.ut a
fortnight these eggs hatch.

The newly-hatched slug Is at first white, but soon a slimy m.^tter «m/.e.
out of the skin and covers the upper part of the bo.ly with an ollve-colou,e.l
Btlcky coating. After changing its skin four times, it attains the length or
half an inch or more, and Is then nearly full-grown. It is a dlHgustlng-lookini.'
creature, a slimy, blackish, cr olive-brown slug, with the anterior part ..f its
iHMly so swollen as to resemble somewhat a tadpole In form, and having ,-.
disagreeable and sickening odour. The head Is small, of a re<ldish col.,„r.
and is almost entirely concealed under the front segments. It is of a dull
.vellowish colour beneath, with twenty very short legs, one pair under eM-li
segment, except the fourth and the last. After the In.st moult It loses l,s
slimy appearance and dark colour. .- ' ..pears In a clean, yellow skn, entirely
free fro.n sl.rae. Its form also is changed, being proportionatelv longer. In a
few hours after this chaHg. it leaves the tree and crawls or falls' to the groun.l,
where it buries itst^lf to a depth of from one to thrtH- or four inches lU
repeated movements of the body the earth is pressed firmly on all slde-s. anil
an oblong oval chamber is formed, which is afterwards lined with a stlckv.

Ihis species is remarkable in tliat two of tlie tin-ee bromls of moths which
api.ear during the year are of a l)right orange colour, while those of the third
bro(Hl are reddish-gray. It is an example of what naturalists call dimorphism

Tlie eggs are laid in the spring, on the unfolding leaves of apple and other
tnn-s and bushes, the larvie s«Hm liatching and feetling on the you. g foliage
some of which they roll into a protective covering.

Here they continue fecnling for about a month when they pupate within
the folded leaves, and a wwk or so later emerge as small orange-vellow n.oths
Tliese moths lay eggs for anotlier l>r«Hl of larvas the moths of wliiclj are also
.vellow. and they in turn lay eggs for a third broo<l, which develop in the fall
as reddish-gray moths. These winter in shelteretl places and in the following
spring deposit tlieir eggs as previously stated.

Vl»e caterpillars feed together in numbers, usually stripping the branches
of leaves as tliey pr<K-e.'d. When handled, they emit a transparent fluid
having a stn.ng acid smell. When full-grown they desctMid to the groun.l and
• onceal themselves uncler leaves or slightly below the surtax, after a time
changing to l)rown clirysnlids.

Tlie motlis usually apj.ear aI)out .Tune, and are describ.Hl as f„n„ws —
The fore-wings are dark-brown on tlie inner .-.imI grayish cm the outer margin
with a dot near the middle, a spot near each angle, and several longitudinal
streaks along the hind margin, all dark-brown.

Tlie hin.l wings of tlie male are lirownisb. or dirty white: thos,> of the
female dusky brown, \\-lien expanded, tlie wings measure 1 to li. inches
across.

The female dejM.sits her eggs in a cluster on the under side ..f a le-if-

a Viscid liquid, which dries Into a sort of varnish, by the parent n oths • i
takes place during July and August. ' ''^

On the principle that an oun<e of prevention Is worth a ,K>und of cure
the easiest way of .h-aling with this .n-st. es.Knially on sn.all tls is to
lestroy the egg n.asses. either ren.oving then, for the purpose, or c^thig c ff
he twigs on which they are tound. Careful sean-hing Is r-e<p. red o d this
but the work can be acon.plishcd In the .lorn.ant season, Jhen there is "t
so nuuh press of work in other ways. If the caterpillars are allow^Ito hat^^
out they are easily detected by their conspicuous web or nest. ftl e e" r -
a.u a e ,...rti..ns of the day they will all be found in these nests an ca" be

a week or two after thin time. To Hhow how thin varlen from year to year, let

accctrdluK to Aldrich. the Hrnt moth Litiyeanil altont .Inne l(!th. prohaltly tw<»
weeks later than usual, while th» bless, ais did not fall till June 14-17. This
.rear, the first moth apiieannl in m. c.ige May ISth, while the api»les were In
full blossom alH)ut May 14th. This was due to the muisually warm, dry
Hpring which forced out both moths and tlowers a ctmple of wwks earlier
than usual. To Ije In time to catch the first worms, whicli iaigUt liave come out
before those in my cage did. I had to si.ray ltet(»re most of the petals liad
fallen. The transformations of the worm take alwut fifty days, and may
be shown graplilcally as follows: —

(1.) Winter worms change to motlis about when i>etal8 are falling. First
spraying.

(2.) Moths mate and lay eggs in a day or two.

(.'{.) Eggs ItJitch almost always in ai)out eight or ten days, while petals
close lu about ten d'lys. •• Firnt hrfntd of trorniH."

Many advise a second spraying at tills time, to get the jiolson into the
ralyx <ups iH'fore tlie last of them close, and to catcii tiie last of the young
worms of the first bnxMl l)efore they enter the apple. No spray can affect the
worm when once he has entered the fruit unharmetl or uniwisoned.
(4.) Worm remains in apple about eighteen or twenty days.
(5.) He then conies out by enlarging the tunnel he made on entering, or
by eating out a new tunnel, and b is himself down from the apple to the
ground by a silken thread, or crawls down tiie trunk of the tree, set'king a
hiding place in which to pupate.

(«.) Having found such a hiding place, he wraps himself up as did the
winter worm, gradualy changes to a pupa, and comes out as a moth in aliout
twenty days. Simpson found tliis time varied from eleven to forty-nine days
in Soutliern Idaho.

(7.) The eggs are again laid, and they again hatch In about eight or ten
days. As this forms the time for the third spraifinn. or the second, if we liave
omitted the last one mentioned, we must again have recourse to the l)reeding
cage. In fact, it is niiuh more essential that we should know the exact time
this set of moths ai>pearK than the first, as we are more or less limited in
the first spraying liy the dii.e of full flowering. So, as soon as the worms
come out of the apjiles, which can be told by the bands on your trees (and
you should use bands), catcli some, place them in your cage, watch when the
first moth apjK'ars, add eight or ten days for hatcliing of young worms, and
yon wil! know when this xrvnttij hmuil of worm?! is re.idy to enter the apples.
Your spray should Ite on tiie a|)ples soon after the emergence of the first
moth, in order to catcli early as well as late worms of this brood.

(Fio. 46.) Infested Apple— Halved.

The first apparent sign of infesfaition is the exudation of Juice from the
fruit, at the itoint where the larva enteretl, which generally dries up in the
form of a little bubble, grayish in colour. The point of entrance is often
between two fruits which touch each other, or under a leaf which covers part
of the apple attacked. Later on, when the larva has left, the small hole in the
side of the fruit through which it escaimi can be seen on close examination.

Many fruits were found to l)e infested both with this and the lesser apple-
worm (Grai>hoUtfia pniiiiiora, Walsh). The full-grown larva is smaller than
the last mentioned. It has been descrilml as follows: Nearly cylindrical in
shape; slender; about %, inch in length, when extende<l; body whitish, some-
times greenish-white, with black head; r.iufuce of the hoily une%-en, intraseg-
mental folds deep; as also a medium transversal fold on each segment.

Japankse Fhiit-Borer (Larcrna hcrellera).

An Item iiiuw-nml in a paiH'r i»ubll«h«J5l in Sacranu'iito. Cal.. in NovomlM^r
10(»7, to the fflft'ct tlnit (J.OOO boxes of apples from Orcas Island had been con"
dennied In San Francisco on account of being infected with bud niotli. and tli.u
a quarantine had been declared against Britlsli Columbia fruit for tiie same
reason. This absurd statement naturally called forth an inquiry from this
Department as to what was really meant. Whereupon Mr. J. W. Jeffrey tlie
State Commissioner for California, exi.lained that the api)les In (luestlon iiad
bwn condennied by Mr. E. M. Ehrhorn, on account of being infested with tlu-
Japanese Fruit- Borer (Laicnm herellera). Mr. Jeffrey remarlcs furthermor*.
" The ndstake as to the Identity of this Insect was not ours, and I hoiie you
will give the facts to your people."

Mr. Ehrhorn, who, Mr. Jeffrey says, is an entomologist of national reputa-
tion, says: —

" Your letter of Jainiary 9th, addresswl to Mr. J. \V. Jeffrey, State Com-
missioner of Horticulture, Sacramento, Cal.. was sent to me, as in it you
express a desire for specimens and a description of the i)est found in a ship-
ment of apples from Orcas Island. I am sorry to say that I have no si)ecimens
of the insect, which is the apple fruit-borer, Laverna herellera, and not the
bud moth Tmctoccra occelana. as was report^ in the various papers. I dont
know how your Province came to be mentioned, but sometimes reiwrters get
things mixed. I have from the start said that the fruit came from Orcas
Island and was shipped from Bellingham to San Francisco."

Under the circumstances, it is considered best to publish the following
descriptions of two Japanese insects taken from the I'. S. Year Book, 1807 :—

" Of Japanese Insects we need mention at this time only two sjiecles
These are the apple fruit-borer (Larerna herellera, Dup.) and the pear fruit-
borer (Xephopterifx ruhrizonella. Rag.). Accounts of each have been sent us
by Prof. .M. Matsumura. of the Agricultural C«.llege at Sapporo. Tlie figures
which we introduce of these two insects are re-drawn from Prof. Matsumuras
sketch€>s.

Apple Friit-Borer (Larcrna herellera. Dtp.)

" Is said to l)e the most troublesome insect with which the fruit-growers
of Japan liave to contend. It is thought to have beer introduced into the
c-ountry. and is now met witli there wherever api)les are grown. The larva-
live only in the core of the apple, injuring the see«ls. They mature in almut a
niontli. nmke a pas.sage through the flesh of the fruit, crawl or drop to tli<«
ground or emerge from the fallen fruit, making wlilte cocoons in tlie earth
and hibermiting in the pupa stage. It procluws only one br«KHl eadi sea.son.

"On the day that these words were written. November ]lth. 1S07. parts
of two apples were received from Mr. Craw, at San Francisco, whi.h a
pa.sesenger on the steamoi from Jai.an had given liim. and whh-h showed
evidence of the work of what is very probably this insect. No .siHHlmens of
the in.sect itself were found, but the apples contained tlie larval burrows lead-
ing to the core, and two of the s(hm1s had iKH'n eaten out. It is not likely that
the passengers would have bought daniageil applc-s in Japan, and, therefore

Renter, in an article on an outbreak of tiie same insect in Finland, dissents, as
I had done itreviously, from the opinion that our insect is the same as tlie
Japanese Lavema hcreUcra."

The report referred to by Dr. Fletcher, contains the following statement :—
"An Interesting account of a Japanese insect (Lavema herellera, Dup.).
which, if different, resembles In most respects the apple fruit-miner in a very
remarkable manner, Is given with an excellent figure in Bulletin No. 10, new
series. Division of Entomology, U. S. Department of Agriculture, by Prof.
Matsumura, of Sapiwro, Japan. In a foot-note to this article. Dr. Howard hns
suggested, from the resemblance of Prof. Matsumura s figure to bred specimens
of the apple fruit-miner from British Columbia, which he was good enough to
examine, the identity of the two insects. Although it is true the figure cited
and the perfect moths of the ai.ple fruit-miner do agree closely, the habits of
the larva?, as given by Prof. Matsumara (loc. cit.) and as described in niv
annual report for 1S9<!, differ ujKJn what seem to be such Important characters
that for the present I can hardly think that the two attacks are by the same
si)ecles. The writer of the article referred to says that the larvre live onlv
in apple cores, injuring the seeds, that there is usually only one egg deposited
on each apple, and that the cocoons are made In the earth whenever possible.

149

" The British Cohiniblnn Inm-t vpry rarely nttiuks the cores ami seeds of
the fruit. There are usually several, two, three or more, larvie In each apple,
and the cocoons are made beneath flakes of the bark on the trees or beneatli
leaves or rubbish on the surfai-e of the ground."

(o) and (b) larva; (c> beetle; (d) pupa. Enlarged.

The cffffn are deposited about June, near the base of the trunk of the apple
tree. The larra eats Its way through the outer bark to the Inner, and takes
about three years to develop. It works In the sapwood. where It forms flat,
shallow cavities, filled with sawdust-like castings. These are often seen on
the bark, and indicate where the " Iwrer " Is at work. As it reaches maturity.
It cuts a passage upwards Into the solid w<kh1 and then curves towards the
bark. In this channel It enters the pupa stage, about spring. When fully
developed it is an inch long, with a round head that distinguishes !t from the
flat-headed borer, which also affects the apple tree.

The imago is a slender beetle, one inch long, with two broad, wliltlsh
stripes on the wing covtrs, and long Jointed antennte. It appears about
June.

(Fio. 55.) (F„, 58 )

It Is quite distinct from the cane-borer, having in the larval state sixt.cn

legs, six of which are fully develope<l, the others not being very well d.ti I.

The parent moth Is cK ar-wlngetl. with a black body, prettily baud.d nii.l
marked with yellow. The eggs are deposited In July on the leaves of the
raspberry, and the young larvse, when hatched, find their way to the canes
and feed upon the pith In the Interior, gradually working down to the ro..t
where they winter. In the following spring they work ui) again, usually
through a fresh cane, to a height of six Inches or more above ground, and ear
the cane nearly through, In iireparatlon for the exit of the future motli.
Within the cane and near this prepare<l siwt the change to chrysalides takes
plac-e. and these, when the time approaches for the moth to escaiie, burst
through the outer skin of the canes, and the moths sfjon take their flight and
commence to lay their eggs, as previously stated.

Little can be done towards the destruction of this pest, other than
destroying the Infested roots as soon as they are noticed. The application ..t
boiling water to Infested roots Is advised by a Callforulan writer, but applica!..!"
only to very limited areas.

The maggots which are fcnmd attacking cabb.-.ges. radishes, cauliflowers
and turnips, and those in onions, and in In'ans and corn, are very sindlar
but they belong ti» three dlffere .pe<-ies, Phorltia braxsUa: BouchC' attacKing

the crop witli a light dressing of nitrate of s.Hla, 2(J() lbs, to the acre.

The i)erfect filths (.f all these nniggot^s are very similar to the ordinary
observer and may be descriluHl as slender flies, somewhat smaller than the
ordinary liouse fly. which fly ab«.ut close to the ground an,l lav their white

Remedies.— Vp to the present time It cnnuot be olnlmed that any i^rfwtlv
efficacious remedy has been .Uscovered for root maggots. In certain years
they seem to be so extremely abundant that even the beat remedies nierelv
seem to prolong the lives of the plants, and only a very small proiK)rtlon of ",
crop can l.e savetl. In ordinary years, however, nmch can be done to pr.)t.H t
crops liable to attack, and the following are the remedies which ha\ • u'lven
the best results : —

For Onions.— White hellebore dusted along the rows once a week
from the time the young plants appearetl above the ground gave coni'-
luiratlvely clean onions, very few being attacked. Fresh gas lime broadca«.t»Ml
over onion fields at the rate of two hundredweight to the acre had a similar
effect; but, when the caustic lime came in contact with the young onions
they were burnt out. A light dressing between the rows of onions of tlu'-
same material gave almost as good results as where it was distributed over
the whole field. Wlien onions have begun to form their bulbs, the earth may
be hoed or brushed away right down to the roots, and in some years tli •
maggots do not i)enetrate the bulbs. As soon as the earth is hoed away in
garden practice, a dusting along the rows with white hellebore makes\hi.
protection more complete.

Dressings of salt, Paris green and plaster, and wood ashes have l)een
found useless in protecting onions from the attacks of root maggots.

For Cabbages.— (1.) Tarred Pai)er Disks.- Pieces of ordiuarv tarral
paper three inches in diameter, with a silt running to Ine centre 'so as t..
allow of their being placed around the stems of young cabbages and cauli-
flowers at the time of planting, and pressed down close to the ground, will
prevent to a large measure the flit3 from laying their eggs on plants so
protected, or will kill the young maggots.

(2.) Insect Powder.— About half a tea-cupful of a decoction of
pyrethrum insect iwwder (four ounces to a gallon of water), or of
white hellebore of the same strength, iwuretl around the root ot ea4 plant
after drawing away the earth, right down to the roots will destroy any
maggots whkh may have started to work. The earth should be put ba.k
again and the plants well hilled up, when new rootlets will soon be formed.
A light sprinkling of nitrate of soda, or some special fertilizer, will ei.c irage a
quick growth and much help the plants to overcome attack. Dressings of one
oume to the square yard may be used for this purpose. Cabbage plants
should be examined late in June to see if the maggots are at work. The
earlier the treatnjent with Insect powder or white hellebore Is applied tlu-
more effective it will be. If the mixture Is applied to the roots with a force
pump, although more liquid is consumed, It has the advantage of dlslodgln;:
many of the maggots so that their injuries cease at once.

(3.) Cheese-cloth Inclosures.— A very effective and practical means <.f
prwurlng early racUshes. cabbages and cauliflowers, perfectly free from ro..t
maggots. Is by growing them beneath cheap frames made of light wo.m1
covereil with cheese-cloth. A convenient size for small beds Is 8 feet long '
feet wide and 2 feet high. This frame can be made for about 25 cents, of (in.-
and a half inch square wixhI, imitetl together at the corners, and with tL.-

Ex,H.rln.e«ts conducted by Prof. M. V. SUngerland. of Cornell University
give the results of efforts to discover a practicable method of preventing the
ravages of these pests, and a study of the life history of several c.,muion
species, m Bulletin No. 107. He says: "Both defensive and offensive measured
were usecl In our ex,K^rlments. Thus we tried to protcH^t seed from the
ravages of the wire-worn.s. and we also tried to destroy the InscKts In each
of three different stages of their exlstence-as wire-worm or larva, pnpa. ,ind
adult: no eggs were obtalmnl uiK.n which to exiK^rlment." The general results
are succinctly as follows: That It is not practicable to protect seed by the use
of the various ,K>l8ons and other means. That starvation by the growth of
supposed luimune crops, such as buckwheat, mustard and ra,K.. was not
successlul. That destruction by means of Insecticides, such as kerosene, crude
petroleum, poisoned dough and bisulphide of carbon, were useless against
wire-worms. That substances that also act as fertilizers, such as salt
kalnlt. muriate of potash, lime, chloride of lime and gas lime, to be effective'
had to be used in such quantities that plants were destroyed, and the exi^^nsJ
too great for practical pur,M,«es. Of starvation by clean fallow, he s,iys-
It has been the general belief that the wire-worms which Infest our fields
c^uld live but a short time In soil in which no vegetation was ullowc.1 to
eTo^^• No experiments were recorded, however, to show how long the worms
could live in such soil. ""luis

" We kept several experiment cages in ' dean fallow ' for nearly a year
and more wlr^worms remained alive (many of them passed through thci
transformations to the beetle stage) in these cages than in similar cages in
wh ch grass was kept growing. Therefore, we would not advise the farmer
to lose the use of his land for a season and the labour nec-essary to kcn^p It
free from all vegetation, in the hope that he may thus starve out the wire-

fron.sc,.d pease in aut.nnn or i., spring, leaving a small round hole.

The ife history and habits of the pea weevil are well known. The c^.- is
a: .n th.> outsi.lc of the younu ik>,1. and the grub, on hatching, eats its wav
u ami penetrates the nearest pea. Here It re.nains until full-grown, ensu-
ing the interior of the pea and passing through all its sta..s fron a • le
fleshy grub to the pupa, an.l then to the perfec. beetle. As a rule, the bn- les
do no under ordinary circumstances, leave the pease until these are sown
he tol lowing spring. Son.e of the beetles, however, in certain seasons, es.-a pe
fiom the pease. (Hvasionally as early as harvest time, or during autun n

hut can he us«hI for feetl. The greatest dittk-ulty of all Is wltli regard to the
IK'ase whieh are shelled out in the tleld at the time of harvesting. Tills, how-
ever, will Im> to a great measure ohvlatinl hy reaping early, as the wn-d will
not shell out nearly so much as when left till the regular time. The cleaning
ui» of inm fields, moreover, hy turning in hogs is a generally ret-ogniml
practice, and the work Is done tlmroughly. Where hogs iire not avaihihh'.
lK)uitry will d«» the same work, and, where neither of these can he us.h1, the
land should Ik> plouglunl so d«'«>ply that the wetnlls cannot work their way
out when they leave the i>ease. I am aware' that it is not the <ustom to
plough u!) pea tields for fall wheat, hut 8lmi»ly to cultivate or dl.«' them.
biK-ause the land is left In such excellent condition; but it must he reniem-
l»er<Hl that the loss from the p«>a weevil Is now excessive, and. if this small
change In methwl can be shown to be of great advantage, it surely Is worth
a trial.

Another dlffl<-ulty suggesttnl Is that it would l)e hard to get all iK'ase
thresluHl bt-fore the autumn emerging weevils escaiioil. on account of the
small number of threshing machines wlilch would Ik- available. In reply to
this. exi)erience has sliown that demand will always product' supply; and I
feel sure that the lnii)lement makers will not lose such an op|K»rtuiiity o
pushing their business.' The mudi higher price obtainable for tlie enrly
tlireshtHl iR'ase. to say notlung of the enormous value of future crops due to
controlling the weevil, will very soon repay to the farmer the Initial exfK'nse.
Where, however, there is no |Hissibility of getting a threshlm: machine. I
would draw the attention of growers to the old-fashioned meth.Ml of treiiding
out the iiense with horses. That this Is advantageous is indicat.'d by the
fact that some of the se«l merchants ps^y a higher i>rl«- for j.case tiireshed

think you « annot do better than to follow the dIrectlouM given for the dent ruc-
tion of that Insect.

"Trent descrll)eH the weevil mentloniMl as follows: 'This large snout-
beetle kills the twigs by gnawing off the tender bark. In the earlv part of
the s«.ason before the buds Imve jnit out. and later in the vear it d.-stroys
the tender shoots which start out from old w.mhI by entirelv devouring
tliein. It attacks, by preference, the tender growth 'of the apple, tlu-igh i-
win also make fre«. with that of the peach, plum and iK-ar. and pn.lmblv of
other fruit, as well as of forest tn-es.

•"This bt>etle belongs to the same family as does the Plum Curcnllo- It
is distinguished from most of the otlier snout-lKH-tles l,v the antenn-e'or
horns being straight Instead of elbowed or tlatl-shaiKMl, as thev .,re in the
common Plum Curculio, for instance.'

"(Yoiu- pea wwvll has dwidwlly ellMiwed antenn.'e.)

"•The female. In deiwsiting, first makes a longitmlinal excavation with
her jaws, eating m.war.ls nnder the l.aik towards the end of the brand,
and afterwards turns round to thrn.st her eg- i„t<, tl..> ...xcavation The
larva hatching from the egg is of the usual pale.vello« ,„lonr with a fnvnv
head. We have watche«l the whole operation of depositing, and returning to
the imnctureil twig a few days after the oix-ratlon was isTformcd iiave c-ut
out the j-oHug larva; but we do not yet know how long a tinie'tlie Iirva
nmls to come to its growth, nor whether it underpn-s its fransform.iilo„«

In doallnK with thP8e jK-ste on cultlvntcnl plants, a Judicious prunlnR or
thinning out should be the flrst step taken; In winter the treatment ad>Mj
for the oyster-shtll bark-louse Is effective, and any that escape may be enslly
destroyed In the early summer, when the young lame emerge from the ecirs
by using either of sprays Xo. 2. 0, or 7. as directed. But It must be borne h."
mind that, to be effective, this summer spraying must be do.ie before the
Insects have protected themselves with defensive scales.

OYSTKR-SHKLL UaKK-LOISK OB ScALE ( J//////««p/« po,„Orum, BoHUIIK.)

Apple-tbek Babk-lovse.

m , i ' ' ^*-^ (FlO. «5.)

This pest occurs In th, ,rm of minute scales, about one-sixth of an Inch
long, of a brownish or grayish colour, closely resembling that of the bark of a
tree and somewhat like the sholl of an oyster In shape, adhering to the surface
of the bark, and placed Irregi rly. most of them lengthwise of the limb or
twig, with the smaller end upwanls. In most instances the branches of apple
trees may be found literally covered and crowded with these scales; and
where thus so prevalent they seriously impair the health and vigour of the
tree, and sometimes cause ith death.

Under each of these scales will be found masses of eggs varying in
number from fifteen or twenty to one hundred or more. These, during the
w-inter or early spring, will be found to be white In colour, but before hatching
they change to a yellowish hue. soon after which the young insects appear.
This usually occurs late in May or early in June, and if the weathei Is cool
the young lice will remain several days under the scales before dispersing over
the tree. As It becomes warmer, they leave their shelter and may be seen
roving about looking for suitable locations to which to attach themselves
Their aetua! length being only about one hundredth of an inch, to the uuaideil
eye they a,)i)ear as mere Hym-ks. When highly magnified they appear as at '^ \
large proportion of them soon become fixed around the base of the side shoots
of the terminal twigs, where, inserting their tiny sharp beaks, they subsist
upon the sap of the tree. In a few days a fringe of delicate waxy threads
issues from their bodies, as at 3. Gradually the insect assumes the form

of the antennw of the young lice; 1 shows the i-nM highly niagnlrtetl

By the middle of August this female hnise has be«-onie little less than a
bag of eggs, and the process of de|K>sltlng these now begins, the body of the
parent shrinking day by day. until finally, when this work Is «.>mpletiHl It
becomes « mere atom at the narrow end of the scale, and Is scarcely noticeable.

The scales of the male louse are seldom seen; they are most fr«iuently
found uiM.n the leaves, both on the upin-r and under sides; they are snuiller In
size than those of the female, and different also In shai>e.

In the orchard and Its Immediate nelghbourhooil It may be spread by being
carried on the feet of birds, or attached to the larger Insects, or may be aUled
by the wind In passing from tree to tree, while It Is Itself so brisk In Its active

Although this insect essentially belongs to the apple tree. It Is frequently found
on the pear, and sometimes on the plum.

Apple trees should be examined during the winter months for this pest
TV hen r)resent In large numbers on the trunks and main limbs, a goml scraping
will remove n.any of them, and prepare the way for elTw-tlve spraying or wash-
ing operations. The No. 1 spray Is a good remedy to use ; two applications are
necessary, and the mixture should Jje used quite hot. Another very goml appli-
cation to be used with a brush or swab Is made with 1 it), of concentrated lye
to 2M. gallons of water. Both these remedies, of c-ourse. can be us«l only
during the dormant season. Still. It Is almost lmiK)sslble to cleanse the trees
entirely in this way. especially the smaller branches, and hence the Insect
should be fought also at the time when the eggs are hat.hing and the young
lice crawling over the limbs, as then they are tender and easily klll«l With
this object In view, the time of hatching of the remiumts left after the winter
work should be watched for. and while the young lice are active, before they
have secreteil their protecting sc-ales. the trees should be thoroughlv sprayed
or washed with a solution of soft soap and washing soda, or with either of
sprays 2. C or 7.

In experimenting for other pests. It was accldentiv discoverwl by Mr
W. T. Macoun. Horticulturist. Central Ex|H>rlmental Farm. Ottawa, that ordi-
nary whItewaKi ma«le of good lime, painted on the trees, had the effeit of dis-
solving the scales of the Oyster-shell bark-louse, so that they could l.e brushed
off. This remedy, whilst effectual where It can be appliwl with a brush, can-
not, of course, be u8e<l on the small branches, which should Ih> sprayed as
recommended above.

San Jose Scale {AttpUUntuH pernirlnHUft).
The San Jose Scale Is the most destructive of all i>est8 In neglected
on-hards. Nevertheless, by Intelligent effort, It can be more easily controlled
than any other first-class orchard pest : and when we come to realise that the
one annual winter application of the lime, sulphur, salt sf.ray. which is all that
Is necessary to reduce Its ravages to the minimum, is also one nf the b«.t
general " clean '.ug-up " sprays that has yet been devised, we shall. r)erhaps. be

EnUtmoloail, V. ti. Department of Agriculture.)

The females live and die Ijeneath their scales, never leavhiR them ; but in
April the males molt fo: the last time, and soon thereafter emerge from under
their scales as minute, active creature.s. with fully-develoi>ed wings. After
mating the males die.

In May. possibly earlier, under favouralile conditions, the females begin
to give birth to living young, and may continue to prfMluce for si.\ weeks or
longer. The yonng are minute, light orange-yellow, active creatures, witlj e.ves,
bristle-like mouth parts, two antenna', or feelers, and six legs. After emerging
from under the protecting s. ,le of the parent, each wanders over the surface
of bark, fruit or leaf until a suitable situation Is found, when the legs aud
antenna; are foldeil beneath the bod.v, the bristle-like beak is slowly worke<l
through the outer bark into the living tissues beneath, from which it draws
its sustenance. At any time during the summer months hnndre«ls of thes«>
little i)ests may be seen, even with the unaided eye, as they crawl alwut over
the bark or fruit of infesteil trws.

Even before the young Insect has attached itself to the bark, the se<Tetlon
of the .scale has begun. At first it consists only of a fluffy, white mass of fine,
waxy threads, Vvhich for the first day or so of its existence causes the young
San Jose Scale to a|ipear as a minute, downy white 8|)eck urwn the bark. As
these filaments become more abundant they become fu.sed Into a more and
more compact scale, and assume a yellowish colour. Later the young scale-
Insect molts several tmes during its growth and the full.v-developed scale
is thus made up of fused wax filaments and the several molted skins.

The general distribution of the Hcale through Canada and the States
has l)een brought alwut by planting unfumlgatwl nursery stcKk. Prof. L. O.
Howard, of the United States Departnunt of Agriculture, tells us tliat. in
spite of the wide dissemination of scaly fruit in this country, and to some
extent abroad, there is not a single authenticatetl instance of the scale having
been established from such ninterial.— ZVom pai)cr by ^^'illiam lloitkitis, read
before Ontario Fruit-iSrowcrH' Aumeiation, yort;iihcr. J!K)7.
How TO Control the San Jose Scale.
The .S'nn Jose Scale a Permanent Factor in Fruit-<lroirni!/.

The San Jose Scale is so widely disseminated and has become so firmly
established In ths principal deciduous fruit regions of this country that its
extermination is now in most cases out of the question. In the r ain. theri»-
fore, the San Jose Scale nuist be recognised as a permanent 'actor, to be
regularly dealt with as are other Insect evils or the fungous diseases of plants.

E:;termlnatlon Is possible only where the scale is detec-ted at the very
outset on new or recently jilanted nursery stock, or, at least, before any
considerable chance of spread has been affordetl. It is true that by the
greatest care in the introduction of nursery stock the San Jose Scale may
be kept out of districts now free from it for years, i»erhaps. and one is
warranted, therefore. In adopting every precaution to avoid introducing this
scale and even to attempt extermmation wherever the conditions are reason-
ably favourable. There is only one certain method of exterminating the
scale, and that is in digging up and burning all Infested trees. This is an
heroic remedy and is advlsetl only under the conditions of very recent Intro-
duction of nursery stcx-k — in other words, where the scale is discovered
within a few months after the purchase of the infested trees. If the scale
has passed an entire breeding season in an orchard, it will have spread
much more widely than any inspection will indicate and. very likely, will
have gained a foothold on wild and ornamental plants, other than fruit trees,
from which it will i-e-lntrofluce Itself into neighbouring orchan.s or info
n»w il.i.li'ics. howeve: thorough 'uayhave 1 eei; th* attempts to crclicu' it.
The San Jose ,9rf,h; fUii h^ fniitKilInK

While, therefore, one is undoubtedly justified in asserting that the Sun
Jose Scale is to be a permanency, it by no means follows that tlio profitable
growth of deciduous fruits Is seriously menacetl on this account. The
experience in California, covering many years, has abundantly demonstrate<l
that this scale Insect can be controlled, and the more recent experience in
the East iwints Indubitably to the same conclusion. In other words, by
proper repressive and remedial treatment, the value of which has l)een
demonstrated by much practical exi>erlence, an orchard can be protected from
serious Injury and kept in a good paying condlton, so far as influenced by
the San .Tose Scale.

In view of the above, It is certainly very unwise and wasteful to dig up
and burn a large portion of an orchard because It is infested with this scale
insect, especially since the re-planted stock, even If clean v'len purchased,
would, with little doubt, lie in the same condition of infestation In i very
short time.
