"expanded." There are various sorts and sizes of insect-pins, but those
made by Klaeger, of Berlin, are generally preferred at the present time by
the leading entomologists of the world. The French pins and the so-called
"Carlsbader pins" are too long and the points are too fine, and, therefore,
too likely to be injured to make them desirable. The English pins are too
short, and except in the case of very small insects, are not used by the
best collectors. Insects should be mounted high upon the pin, _i.e._, in
such a way that not more than one-fifth or at the most one-fourth of the
pin shall be exposed above the body of the specimen. Dr. Staudinger, the
celebrated lepidopterist of Germany, makes it his rule to mount all his
specimens in such a way that the wings are elevated upon a plane one inch
above the tip of the pin. The writer has had the greater part of his
collection, of over fifty thousand specimens of lepidoptera, mounted at an
average height of seven-eighths of an inch above the points of the pins.
The "English method" of mounting low down, and only leaving enough of the
pin exposed below to permit of fixing the specimens in the cork at the
bottoms of the drawers of the cabinet, is rapidly passing out of vogue,
even in England, and is giving place to the "Continental Method." Insect
pins are of various sizes; adapted to the size of the insect which they are
to carry. The most serviceable sizes and which will be proportioned to the
majority of the insects which the collector is likely to take, are
Klaeger's No. 3 and No. 5. For very large insects higher numbers may be
employed, and for smaller insects lower numbers, though in the case of the
latter it is perhaps better to use the short English pins and then to mount
the specimens upon the bits of cork or pith which are themselves mounted
upon the longer German pins. Such mounts are known as "double mounts" (see
Fig. 96). The writer desires to utter a caution against the use of the
common black insect-pins so often sold by dealers, and the sole stock in
trade of one or two firms of opticians in this country. They are very
liable to rust at the point and to bend, and are totally unsuited for use
in humid, tropical, and semi-tropical climates, or for collections which
are to be transported far over the seas. Beetles should always be pinned
through the right elytron. Bugs should be pinned through the scutellum, as
the small triangular piece between the elytra is called. All other insects
should be pinned in the middle of the thorax, and care should always be
taken to set the pins perpendicularly.

[Illustration: FIG. 97.--Frame for Mounting Beetles. a, a, Wooden frame; A,
B, paper drumhead.]
Having pinned the specimen the next step is to expand it properly. In the
case of beetles this is done by simply arranging the feet and the antennæ
in such a way that they can easily be inspected. In doing this it is well
to have a frame seven-eighths of an inch deep, or thereabouts, backed by a
thin piece of soft pine, and covered on top by a sheet of paper, which has
been first moistened and then pasted around the edges, and which when dry
expands like a drumhead. (Fig. 97.) Upon this a number of beetles may be
pinned, their feet drawn out, and there be left to dry. In the case of
lepidopterous insects, and other insects having considerable expanse of
wing, setting-boards are required. These are boards provided with a groove
in the middle capable of receiving the body of the insect, and permitting
of the expansion of their wings laterally. These boards should be of
various widths, so as to be adapted to insects having various expanse of
wings, and the grooves also should be of various depths, adapted to insects
having bodies of various size. The best form of a setting-board, with which
the writer is acquainted, is that given in Fig. 98. The narrow slit below
the groove, which is intended for the reception of the body of the insect,
admits of passing the pin down to a proper depth, and the depth is
regulated of course by the piece at the bottom of the setting-board. The
two side pieces should always be from seven-eighths of an inch to an inch
thick. The best material is soft, clean pine, or, better still, the wood of
the Kiri-no-Ki (_Paulownia regalis_).
[Illustration: FIG. 98.--Setting-Board.]
[Illustration: FIG. 99.--Setting-Board. (After Riley.)]
[Illustration: FIG. 100.--Setting-Block. A, Groove for body of insect; B,

[Illustration: FIG. 101.--Butterfly Expanded upon Setting-Block.]
Instead of setting-boards, setting-blocks (see Figs. 100 and 101), may be
advantageously employed in setting smaller specimens, especially of the
Hesperidæ and the Noctuidæ, the wings of which are refractory, and refuse
to be treated in the method that has just been described. Instead of using
strips of tracing muslin it is necessary, in the case of setting-blocks, to
use threads or cords, which may be adjusted, as is shown in the figure.
Care should, however, be taken not to draw the thread or cord so tightly
about the wings of the specimens as to cut into their vestiture and thus
leave marks.
[Illustration: FIG. 102.--Setting-Needle.]
The insects having been adjusted upon the board, care being taken that the
pin is set perpendicularly, the next step is to draw out the wings in the
position which they are to maintain when the specimen is thoroughly dry.
This is accomplished by means of what are known as "setting-needles" (see
Fig. 102). They can easily be made by inserting ordinary needles into
handles, which may be made of some soft wood. The writer generally employs
as handles for his setting-needles matches, from which the sulphur tip has
been removed. In drawing the wings into position care should be taken to
plant the setting-needle immediately behind the strong nervure of the
costal margin of the wing. Otherwise the wings are likely to be torn and
disfigured. The rule in setting lepidoptera is to draw the anterior wings
forward in such a way that their posterior margins form a right angle with
the axis of the body, which rests in the groove in the middle of the
setting-board. The posterior wings are then drawn forward in such a way as
fully to expose their outline. The next step is to firmly fix the wings in
position, as they have been placed. Some writers recommend for this purpose
using short strips of paper over the wings, others recommend placing upon
the wings pieces of glass, of a size sufficient to cover the entire wing. A
far better plan is to employ strips of tracing muslin, such as is used by
draughtsmen and engineers. These strips may be secured at the ends of the
setting-board by thumb-tacks, and may be drawn down over the wings of the
specimen and securely held by pins in place. Care should be always taken to
nicely turn up the edge of the strips nearest to the body, so that a crease
or depression may not be left upon the scales covering the wings of the
insects when the specimen has been thoroughly dried. The wings having been
arranged, the antennæ and the feet may be brought forward and displayed in
a natural position. Care should be always taken to lower the antennæ so
that they do not stand erect above the head. In the latter position they
are very apt to become broken. A number of such boards may be conveniently
arranged in a box, as shown in Fig. 103, and if strips of muslin are used,
and are firmly held in place by pins, such a box may be transported from
place to place, upon the backs of men or beasts, and the process of drying
the insects may go on _en route_, while the naturalist is conducting his
investigations. In this manner the writer carried four or five large boxes
with him through the interior of Japan (Plate XXIII., Fig. 2), and
succeeded in bringing home with him nearly six thousand specimens, dried
and ready to place in the cabinet. The length of time which is required for
drying, varies of course a little with the temperature, and the amount of
humidity in the atmosphere. In some climates it is almost impossible to
absolutely dry the specimens, in others they dry very quickly. In the
United States a week or ten days will generally suffice to secure that
rigidity which is necessary in a cabinet specimen.
[Illustration: FIG. 103.--Box for Receiving Setting-Boards. _a_, Board
partly withdrawn; _b_, =T=-shaped strip to hold board in place; _c_,
sliding door of box; _d_, tongue on edge of door working in groove at
front of sides.]
The process of drying may be hastened advantageously by placing the
setting-boards in a cool oven. The temperature, however, should not be
above 130° F. Some insects lose their color when dried, and it is
impossible in certain cases to retain them. In some cases also the bodies
of insects shrivel up very greatly and become distorted. It is very often
advisable in such cases to make an incision into the abdomen and withdraw
the viscera and stuff the body with cotton. Spiders should always be
treated in this way, and so also the larger Mantidæ and Locustidæ. When the
insects have become thoroughly dry, and their wings are rigid, they may be
removed from the setting-board, and are now ready for the cabinet. In case,
however, it is desired to transport them, as is the case with specimens
that have been collected upon a journey, they may be pinned in boxes lined
with cork or pith, with their wings "shingled" as in Fig. 104, and they
may, if firmly secured to the bottom of the boxes, be in this shape
transported for long distances; but it is always necessary to pack the box
in which they are contained in an outer box, separating the inner box from
the outer case by at least two inches of straw, excelsior, or some other
light and elastic substance, to save the specimens from being jarred in
transport.
[Illustration: FIG. 104.--Butterflies Pinned with their Wings Shingled.]
Specimens that have been preserved in paper, as described on page 328, in
order to fit them for the cabinet, should be relaxed and then expanded. In
order to relax them, one of the best methods is to place the envelope which
contains the specimen between layers of cloth that have been dampened in
pure water, to which has been added a small quantity of carbolic acid,
enough to prevent mould. Be careful not to add too much carbolic acid.
Another method is to lay the specimens at the bottom of a jar, half-filled
with sand, which has been moistened and well carbolized. The jar should be
tightly closed, so as to retain the moisture. Specimens that have been
fastened with pins may be placed on pieces of board, and then set in a jar,
prepared in the way that has been described. After exposure to the moist
atmosphere of the jar, or to the moisture contained within the towelling,
for a period varying from a few hours to a day, the specimens will be
sufficiently relaxed to permit of them being treated as if they had been
freshly taken, and mounted and expanded upon the setting-board as described
on page 331. It is well to have the top of the jar, before the lid is
placed upon it, covered with a layer of blotting-paper, or some other
substance which will absorb the moisture which otherwise might drip from
the lid upon the specimens below. This is a precaution which is especially
necessary in the case of butterflies which are of a bright blue or a pale
green color, and which are much disfigured by water stains.
Mould is one of the great enemies of the collector, and strenuous efforts
should be made to prevent its appearance in the cabinet or among the
specimens. In order to do this, it is well to secure a thorough desiccation
of the specimens, but where it is impossible to thoroughly dry them,
moulding may be prevented to a greater or less extent by placing between
the paper envelopes pieces of blotting-paper which have been saturated with
carbolic acid and permitted to dry. The sides of the boxes containing the
specimens may also be painted with carbolic acid. Naphthaline in crystals
may be introduced among the envelopes, and this appears in many cases to
serve as a partial preventive of mould. When a specimen has been attacked
by mould, the mould may be largely removed by thorough drying in a cool
oven and then dusting off the specimen with a soft camel's-hair pencil that
has been rubbed in carbolic acid and dried.
Specimens sometimes become greasy, and it is then desirable, if possible,
to remove the grease with which their bodies and wings are saturated. The
only method which can be employed advantageously is that of washing out the
grease by means of benzoline, or some of the allied volatile mineral oils.
By immersing a greasy specimen for a considerable time in gasoline, it is
possible to remove the grease. The specimen having been thus exposed should
be placed in a cool spot, free from dust, and all the gasoline should be
allowed to evaporate. Care should be taken to conduct this process away
from fire and lights, in order to prevent an explosion. The writer has
found that the best method for removing grease is to allow the gasoline to
fall drop by drop upon the thorax of the specimen. The specimen is
therefore placed in a very large glass jar, say six inches in diameter, and
is fixed at the bottom upon a piece of cork, tightly secured in place. The
gasoline is placed above and is allowed to filter down from the bottle in
which it is contained upon the specimen drop by drop. In this way the
grease is gradually washed out, and will be found after a while at the
bottom of the jar in the form of thick globules, the density of which
causes them to sink to the bottom. In the case of some large bombycid moths
the writer has washed out as much as a teaspoonful of animal fat from the
body and wings of the specimen, in the manner that has been described.
The receptacles into which entomologists place their collections vary
somewhat according to the taste and the length of the purse of the
collector. Some large collections are contained in boxes, and most of the
coleopterists of this country, so far as the writer knows, have adopted
these as receptacles for their collections. The boxes should be about two
inches deep in the clear, the bottom should be lined with the best quality
of cork, about one-fourth of an inch in thickness, and the whole papered
inside with white paper. The lid should be fastened upon the lower part of
the box, either by a tongue and groove or by thin strips nailed around on
the inside and projecting above the margin of the bottom portion at least
half an inch. These boxes should also be hinged. The material should be
well-seasoned. Double boxes with cork on the top and on the bottom are
sometimes used, and these may be prepared with backs resembling books, and
may be placed upon their ends upon shelves. They should not be laid one
upon the other, as the insects pinned upon the upper side are liable
sometimes, through jarring, to become detached, and falling out to cause a
breakage among the specimens. The writer employs in his own collection
drawers twenty-two inches long, eighteen inches wide, and two inches deep,
covered with glass, the glass cover being attached to the bottom by a
tongue and groove.
The specimens should be kept in the dark, as exposure to light bleaches
them, sooner or later. Great pains should be taken to keep out dust, mould,
and insect pests, such as Anthrenus and Dermestes. Naphthaline crystals
destroy mites and they cannot exist where it is abundantly present.
Anthrenus and Dermestes may be kept out of collections by naphthaline, but
when they have been once introduced they will remain and propagate in spite
of the presence of the drug. In order to exterminate them various agents
are employed. The best is perhaps chloroform, and next to this carbon
bisulphide. In buying the latter drug, care should be taken to purchase the
washed and purified article, which is not as malodorous as the common
varieties which used formerly to be sold by druggists. It is, however,
highly explosive when mixed in quantity with the air, and care should be
taken not to use it in proximity to a light. It has the advantage of
destroying at once the imago, the larva, and, perhaps, the eggs of
museum-pests. The writer makes it a point annually, in the early summer, to
place sufficient chloroform or carbon bichloride in his cabinet drawers to
exterminate anything that may be living there, and thus secures comparative
immunity from insect attacks.
* * * * *
Instructions as to the use of labels may be restricted to the simple advice
to make them small enough to permit of their being placed upon the pins
bearing the insects, and to have them written legibly. Of course every
label should bear, if it is possible for the student to determine them, the
generic and the specific names of the insects, and that of the author of
the specific name, together with the date and locality of capture. In
writing labels a small crow-quill pen is to be preferred.
A great many instruments of different sorts will suggest themselves to the
collector in the process of his labors as being more or less useful, but
none will prove more so than the forceps. It is impossible to do good work
in the cabinet without a forceps, and those made by Blake, of Philadelphia,
are the very best.

CHAPTER XLIV.
INSECT PESTS AND POISONING.
THE PESTS.--If an island of bare rock should be born to-day in the middle
of the Pacific Ocean, and an unpoisoned skin of bird or mammal laid down
upon it to-morrow morning, I would wager that _Dermestes lardarius_ would
find that skin before sunset. If you were to prepare a skin without poison,
and lock it up immediately in the bowels of a burglar-proof safe, not to be
opened for six months, at the end of that time you would find it swarming
with _Dermestes_. If you ever omit to poison anything in the shape of a
vertebrate specimen, be sure your sin and the beastly bugs will find you
out.
DERMESTES.--The greatest enemy of the zoological collector and conservator,
and one which is world-wide in its distribution, is a small beetle,
one-third of an inch in length, commonly called the "bacon beetle." Its
flight is rather feeble, but "it gets there just the same." The most common
species, _Dermestes lardarius_, is of a dark, dirty-brown color, with a
broad, transverse band of dull gray encircling the middle of the body. The
imago is not of much consequence as a destroyer, but the larva, a nasty,
hairy, brown-backed, and white-bellied abomination half an inch long, and
with an appetite like a hog, is the incarnation of all that is pestiferous.
A skull that has been "roughed out" and put away without poisoning will
soon be literally swarming with _Dermestes_ larvæ, and half-buried with the
brown, powdery excrementation they leave behind. If the curator ever sees a
fine, brown dust falling in little heaps out of any part of a mounted
specimen, he may know that _Dermestes_ larvæ are at work.
Not long ago the National Museum was visited by another species of the
bacon beetle, _Dermestes maculatus_, a gray-colored variety, beside which
his congener seemed harmless and inoffensive. _Maculatus_ was an
unmitigated terror. He disdained to graze modestly on the outside of a
specimen, as did _lardarius_, but simply began to eat wherever he "lit,"
and went straight in to a depth of an inch or so, as if shot out of a gun.
An unhappy stuffed monkey that once crossed the track of this little fiend
had half a dozen neat round holes eaten through the dry skin of his side,
and straight on into the hard tow filling for quite an inch. A gimlet could
not have done the work half so well. The most ridiculous thing was that
this insatiable little monster attacked a plaster cast, and bored it full
of holes also! Fortunately for the National Museum, the stay of this highly
interesting stranger was of brief duration. He came in 1885, and vanished
that same year--so far as my observations went.
MOTHS.--Next in destructiveness are the tiny moths, of which four species
are to be fought in the museum and the household. These are the clothes
moth (_Tinea flavifrontella_), the fur moth (_T. pelionella_), the carpet
moth (_T. tapetzella_), and the grain moth (_T. granella_). The perfect
moth is of course by preference a night-flying insect, and very seldom
flies in the daytime except when disturbed. The imago is harmless, but the
larva--a tiny, white worm no thicker than a pin, and about one-tenth of an
inch in length--will soon shave the hair off an unpoisoned elk or deer head
more smoothly than you could do it with the best razor ever made. Of course
moth larvæ are most active and destructive during the breeding season--the
warm months from May to October--but in warm rooms they sometimes keep at
work all through the winter.
In one sense the moth is the zoologist's most dreaded foe, for the reason
that its work is so subtle and unseen. Often the first intimation the
victim has of the presence of his enemy is when dusting a favorite head he
suddenly knocks off a section of hair half a foot square, exposing
underneath the smooth, bare skin covered with fine gray dust. The larvæ of
the moth attack birds and quadrupeds in one way only, that is by eating the
roots of the hair or feathers, and the epidermis. Mounted heads of large
ruminant animals are the particular prey of these abominable pests, because
they cannot be protected by glass cases, and are seldom touched save with a
feather duster.
In ethnological collections all the garments of skin and leather, and all
the textile fabrics are subject to the attacks of the Tineids, as they also
are to those of the species to be noticed next.
ANTHRENUS.--Although I have seen this "buffalo bug" try hard to make an
impression on mounted mammals, I have not yet seen it do harm except to
furs and leather or woolen garments. The adult buffalo bug (_Anthrenus
lepidus_) is a tiny, round, brown beetle, with white spots on its elytra,
and, as usual, it is the larvæ that do the mischief.
SYMPTOMS OF THE PRESENCE OF INSECT PESTS.--Whenever little heaps of brown
dust are seen accumulating here and there on a pedestal underneath a
mounted specimen, know that dermestes are actively at work somewhere above.
Sometimes the larvæ will even show themselves on the hair, which means a
bad case.
If a perfect moth is seen flying in a case, or resting on a specimen,
search at once for the larvæ. The best way to do this is to go over a
specimen with a rough brush, or a comb, to see if the hair pulls out at any
point. If a tuft of hair gives way at its roots, and you see a bare spot
underneath, it means moth larvæ.
POISONING.--Let us take first the case of a mounted specimen which is known
to be infested with the larvæ of either _Dermestes_ or Tineids. It must be
treated thoroughly all over with a powerful poison, not only to kill the
insects already there, but to poison any larvæ that may be hatched
hereafter and seek to attack it.
If possible, remove the specimen from its pedestal, and beat out of it
whatever dust it may contain. Procure a quantity of alcohol sufficient when
diluted with fifty per cent of water to completely saturate the hair (or
feathers) of the specimen, and dissolve in it some corrosive
sublimate--about one ounce to every three pints of the liquid. The point to
strive for in making up such a solution is to make it as strong with the
corrosive sublimate as it can be without leaving on dark hair a gray (or
white) deposit when the liquid has evaporated. In practice I always mix the
liquid, and then test it with a tuft of black or brown hair. If the deposit
left is quite apparent to the eye, a little more alcohol and water must be
added. The principle of the process is simply this: The alcohol, being at
once very penetrating and very volatile, and also capable of combining
chemically with the corrosive sublimate, is used as a vehicle for the
distribution of the poison. The poison is carried to the roots of the hair
and left there as a deposit when the liquid evaporates. In Chapter XVIII.
the method of applying this solution is described. Arsenic water, also
described there, is _equally good_, and any intelligent person can make up
either solution and apply it successfully without the slightest difficulty.
When the specimen has dried, the hair must be dressed by brushing and
combing it. If the white poison shows on the hair, take a sponge, and with
either hot water or alcohol sponge off the _surface_ of the hair, leaving
all the unseen poison undisturbed. If your solution contains the proper
amount of poison, and is thoroughly applied, I warrant that insects will
never again touch that specimen, even though it should exist a thousand
years.
It often happens that moths get into cases of birds, or mammals, or
insects, which cannot be treated as above without damaging the specimens.
In such an event there are several poisons of a volatile character which
give off fumes so deadly that no insect can live in them. The best for this
purpose is naphthaline crystals, exposed in the cases in little bags made
of musquito-netting, used in abundant quantity, and left in the cases,
which must of course be kept closed as tightly as possible. In insect
collections each box should have a little cone of crystals,[12] as a
standing menace to all would-be marauders. Liquid or crystal bisulphide of
carbon, exposed in saucers on the bottom of a tightly closed case will also
kill whatever living insects may be found therein; but it does not destroy
eggs, and by the time it has evaporated another generation of destroyers
may have been born, hungrier than the first.
A half-ounce bag of naphthaline crystals will last about three months. Mr.
John B. Smith, who published in the "Proceedings of the Entomological
Society of Washington," vol. i., No. 2, p. 113, a very interesting paper on
"Museum Pests," found in treating some boxes of coleoptera that were
infested with _Trogoderma_ that both bisulphide of carbon and naphthaline
killed all larvæ and imagoes, and held all the eggs in a dormant condition,
even through the summer months, until the poison had all evaporated, when
the eggs began to hatch.
At present naphthaline in the form of crystals has become the most popular
of the various volatile poisons, and among ornithologists, mammalogists,
and entomologists is very generally used. It prevents mould, destroys
bacteria and schizomycetes; the salt is perfectly neutral, is not poisonous
to man, and is cheap, costing only twenty-five cents per pound.
POISONING TEXTILE FABRICS AND SKIN CLOTHING.--Objects of this class can not
be put through any liquid poison, for the reason that some would be made
hard and stiff, some would lose their colors, and all would come out in bad
shape generally. To meet the exigencies of such cases one alternative is
to poison the atmosphere of an air-tight case with some of the volatile
poisons already mentioned, and the other is to treat each article with some
powerful liquid poison, applied as a fine spray with an ordinary atomizer
of gutta-percha, which can be purchased for from one to two dollars. The
immense collections of the department of ethnology in the National Museum
have necessitated a great amount of poisoning in both these ways,
especially the latter, which has the merit of being permanent. In the
"Smithsonian Report for 1887," vol. ii., pp. 549-558, Mr. Walter Hough has
published a very complete, lucid, and valuable paper on "The Preservation
of Museum Specimens from Insects, and the Effects of Dampness," which every
zoological conservator should read and hold for ready reference.
In spraying large objects Mr. Hough uses either a Shaw & Geary No. 2
air-compressor (cost, $15) or a four-nozzle gutta-percha atomizer ($2.50),
and the spray is from the following solution:
Saturated solution of arsenic acid and alcohol 1 pint.
Strong carbolic acid 25 drops.
Strychnine 20 grains.
Alcohol (strong) 1 quart.
Naphtha, crude or refined 1 pint.
For treating specimens of ordinary size with the concentrated fumes of
bisulphide of carbon, the National Museum uses a galvanized sheet-iron tank
3 × 2 × 2 feet, which has around its upper edge a deep groove filled with
water, into which the rim of the cover fits when the tank is closed. The
centre of the cover contains an air-hole, which is also capable of being
hermetically closed in the same way. This tank should be used in the open
air, if possible, so that the fumes will not injure the health of the
operator.
POISONING RUGS.--It has long been a problem how to poison a fur rug to
protect it from insects, and yet to keep out of it the dry mineral poisons
which would be injurious to the health of the little ones, the dog, and the
cat, who are "tenants in common" of the bear-skin on the floor. Mr. F.S.
Webster has solved the difficulty by poisoning all his rugs on the inside
with our old and valued friend, arsenical soap. It strikes into and through
the skin, of course, and, contrary to previous expectations, it is by no
means offensive, or even noticeable by odor in the finished rug.
FURS.--Even in Washington, the City of Moths, Mrs. Hornaday carried the
family rugs and furs, and all woolen clothing, through eight summers,
unscathed, by the liberal use of camphor gum alone. If the crumbled gum is
sprinkled liberally into the folds of anything when it is being folded or
rolled up, its protection against moths is assured.
INSECT POWDERS.--For the benefit of the American housewife I will mention
the fact that for the complete annihilation of ants, roaches, water-bugs,
and the like, there is nothing that I know of that is so far-reaching and
so deadly as a powder produced in California called buhac, costing sixty
cents per pound. The price is high, but the powder is well worth it--and
this is an absolutely free advertisement.
THE EFFECT OF POISONS ON THE TAXIDERMIST.--Arsenical soap is by all odds
the safest poison that can possibly be used. It gives off no poisonous
fumes whatsoever, its presence in the mouth, nose, or eyes is always
detected instantly, and the worst that it ever does is to get into a cut or
under the ends of the finger-nails of the careless taxidermist, and make a
festering sore which is well in a few days--a purely local ill.
Dry arsenic is more injurious. It sometimes poisons the fingers of a
careless operator, and if it is inhaled in the form of dust the effect may
be serious. A few persons are very susceptible to the effects of dry
arsenic, others are not. If the blood is in a healthy condition there is
little to fear from it, except through gross carelessness. I have used, all
told, probably more than a hundred and fifty pounds of arsenic in various
forms, and never had an hour's illness in consequence, nor anything more
serious than a sore finger.
Corrosive sublimate is much more powerful and more dangerous. It should
never be used in the preparation of a skin before it is mounted; after
mounting it may, with care, be used quite safely.
Strychnine is far too dangerous to be used by a taxidermist save in
poisoning animals he wishes to secure as scientific specimens.

USEFUL INFORMATION.
_Recipe for Making Arsenical Soap._
White bar soap, soft rather than hard 2 pounds.
Powdered arsenic 2 "
Camphor 5 ounces.
Subcarbonate of potash 6 "
Alcohol 8 "
Directions: The soap should be the best quality of laundry soap, and of
such composition that it can be reduced with water to any degree of
thinness. Soap which becomes like jelly when melted will not answer, and
should never be used.
Slice the soap and melt it in a small quantity of water over a slow fire,
stirring sufficiently to prevent its burning. When melted add the potash,
and stir in the powdered arsenic. Next add the camphor, which should be
dissolved in the alcohol at the beginning of the operation. Stir the mass
thoroughly, boil it down to the consistency of thick molasses, and pour it
into an earthen or wooden jar to cool and harden. Stir it occasionally
while cooling to prevent the arsenic from settling at the bottom. When cold
it should be like lard or butter. For use, mix a small quantity with water
until it resembles buttermilk, and apply with a common paint-brush.
The prices charged for the manufactured article by chemists who make
arsenical soap to sell are out of all proportion to the cost and labor
involved, and every taxidermist who uses much of it should by all means
manufacture his own supply.
_Hendley's Enamel Varnish._--Take equal parts of ether and alcohol, mix
them, and add one-third as much gun-cotton. To every gill of this mixture
add six drops of olive-oil to give elasticity. It is a good plan to keep
two bottles, one containing the varnish ready for use, and the other
containing the proper mixture of ether, alcohol and olive oil, to use in
thinning the varnish when it gets too thick. This is a very superior
varnish being absolutely colorless, and of high gloss.
_The Wickersheimer Solution for the Preservation of Fleshy Objects
Entire._--
Alum 500 grains.
Salt 125 "
Saltpetre 60 "
Potash 300 "
Arsenic trioxide (white arsenic) 100 "
Dissolve in one quart of boiling water. Cool and filter, and for every
quart of solution add four quarts of glycerine and one quart of alcohol.
Immerse the objects to be preserved in this solution, and keep them in it.
It is but little else than our old familiar friend, the salt-and-alum bath,
with enough glycerine added to prevent the excess of alum from unduly
hardening and shriveling the specimens.
_Composition for Use in Modeling Tongues, Mouths, and in General
Fancy-Work._--"Procure 3 pounds white glue, 1 pint raw linseed oil, and 1
pound of resin. Heat the oil and resin, then add hot glue and stir
thoroughly. Thicken with Paris white until the mixture has the proper
consistency to mould when warm. This composition soon dries, becomes very
hard, and can be colored or gilded. Fancy decorations of any design can
readily be made from moulds of plaster or wood, and be glued on to shields
and cases, thereby saving the expense of carving. The above is my own
composition, which I have successfully employed for many years."--(_J.H.
Batty._)
_Composition for Snow Scenes._--"Crush burnt alum with a roller, and remove
small lumps. Add frosting, which has been pulverized in a mortar to the
proper degree of fineness."--(_Batty._)
_Varnish Cutter_ (to remove old varnish from antlers, teeth, wood, or from
the surface of an old oil-painting).--Take a sufficient quantity of eighty
or ninety per cent alcohol, and slowly pour into it clear spirits of
turpentine until the mixture becomes of a milky color. Then cork the bottle
and shake the mixture thoroughly, and it is ready for use. Apply it with a
small sponge, rub the surface vigorously for a moment only, then dip a rag
in boiled linseed-oil and apply it to the cleaned surface. The varnish
cutter acts almost instantly, and if left on too long the surface of a
painting might be injured.
_To Prevent Mould in Boxes of Specimens._--Take some carbolic acid crystals
(forty cents per pound), melt them in the sun, and with the resulting
liquid acid paint the entire inside of each box, and, if possible, pack
contents with naphthaline crystals. This is efficacious in boxes of small
skins of birds and mammals, of insects and the like, even in hot climates,
but of course does not apply to boxes of large specimens which contain a
great amount of moisture.
_To Polish Hard Wood._--1st. Rub the surface thoroughly with raw
linseed-oil, turpentine, and powdered pumice-stone. 2d. Give the surface a
smooth coat of shellac. 3d. When dry, take fine sand-paper and go over it
rather lightly. 4th. Give the surface a good coat of hard oil finish (a
white varnish), and let it harden. 5th. When quite dry rub down with raw
oil, turpentine, and pumice-stone, to soften the gloss of the varnish, and
give a polish instead. For rubbing, use a piece of hair-cloth, or clean
burlaps.
_Cement for Gumming Labels to Minerals and Shells._--"Pulverized gum
Arabic, 4 ounces; pulverized white sugar, 2 ounces; starch, 4 drachms.
Dissolve all separately in as little water as convenient. Dissolve starch
in cold water, then stir it into sugar water, and then that mixture into
the gum water. Boil with great care, as burning will spoil the whole. It is
well to use a tin vessel raised from the bottom of another vessel
containing water. After the starch ceases to make the mixture look milky it
is cooked, but at least an hour's time will be required. Keep in large
mouthed, tightly corked bottles, or when done pour into a tray covered with
strong paper, spreading it evenly over the paper, and allow it to dry. When
dry enough, moisten back of paper and remove it from the gum, dry again
thoroughly, break into fragments and preserve for use in wide-mouth
stoppered jar."--(_Southwick & Jenck's "Random Notes."_)
_Arsenic Water_ (for poisoning mammal skins, etc.).--Water, 4 quarts;
arsenic, 4 ounces. Mix, stir and boil until the arsenic is all taken up.
THE TREATMENT OF FURS AND PELTRIES.--Inasmuch as the readers of this book
may sometime desire to preserve a few mammal skins as furs, or to be made
up as rugs, I will quote entire, _verbatim et literatim_, a circular of
instructions lately issued by one of the largest fur houses in this
country, Messrs. William Macnaughtan's Sons, of New York City. Observe
particularly, however, that skins prepared thus are _utterly worthless to
the taxidermist and the scientific museum_. They are good _for furs only_:
"_Directions for Fur Collectors and Trappers, to Insure High Prices, Ready
Sales, and Save from Losses through Ignorance._--'_Cased:_' Ermine, fisher,
fox, lynx, martin, mink, opossum, otter, skunk, must be 'cased,' that is,
not cut open. In skinning, cut at the rump, and turn the skin inside out
(like a glove) over the body of the animal, leaving the pelt side out. Then
after scraping, cleaning, and drying, turn the skin back again while it is
soft and easily managed, leaving the fur side out. Then put a thin board
inside the skin, cut the natural shape of it, stretching the skin to its
fullest extent, but not so much as to make the fur thin. Too much
stretching spreads the fur over a large surface, and makes it thin and
lacking in richness. A liberal supply of good boards should be kept on
hand. Never use bent sticks, bows, or anything irregular in shape or that
yields. When the above are 'opened' they have a Southern appearance that
lessens the value greatly.
"'_Open:_' badger, bear, beaver, cats, raccoon, wolves, wolverine, must be
'open;' that is, cut open, up the belly from rump to head. After scraping,
cleaning, and drying, stretch a uniformly oblong shape, to the fullest
extent of the skin, but not so much as to make the fur thin. When
thoroughly dry, trim off legs, shanks, flippers, and any little pieces that
spoil the appearance of skin.
"_Exceptions:_ Skunk, long stripe, such as come from the Territories and
sections of California, Wisconsin, Minnesota, and Iowa, cut open and
stretch oblong, as explained. Skunk, with the white stripe (or any portion)
shaved out, blackened, or tampered with, must be collected at half price.
Opossum from Indian Territory, cut open, and stretch oblong as explained.
Chop off the tails where the fur ends, as they make opossum look poorly and
lessen their value. Beaver are sometimes stretched almost round, but appear
very much better stretched oblong. Value by the skin, never by the pound.
They rapidly lose heavily in weight. They bring most sold by the skin.
Muskrats must be 'cased,' but with fur side in. Chop off the tails as
explained. Skin at the nose and make rumps square. Round tails have less
value and do not sell well. Muskrats must not be injured by shooting or
spearing. Trap them.
"Skins that have dried without proper care can be treated same as fresh,
green skins. Otherwise they have no value. Dissolve a handful of common
salt in a pail of fresh water, and apply frequently with brush or rag (to
pelt side only, as it spoils appearance to wet the fur) until the pelt
becomes perfectly soft. Then handle as explained. The same with 'open'
skins.
"_Cautions:_ Do not cure with alum or salt. It injures them for dressing
and spoils their sale. Do not dry skins at a fire, or in the sun, or in
smoke. It often 'burns' them; when they then spoil, and ruin on being
dressed. Dry in the open air where shady. Meaty skins often 'burn.' The
meat and fat on them heats and 'burns' them, and they then go to pieces and
rot on being dressed. Too much warmth curls and spoils the top fur or hair.
Never stuff furs of any kind; dry and stretch as explained. Do not stretch
out the noses and make them pointed. It gives a Southern appearance and
lessens value. Do not cut off heads, ears, or noses, or mutilate in any
way. It lessens value and injures sales. Remove as much of bone from tail
as possible, otherwise the tail rots.
"_Trapping:_ Fur-bearing animals must not be killed till they have at least
a fair growth of fur. Stop trapping as soon in early spring as the fur
begins to shed or becomes thin, or a little faded. These too early or too
late caught furs are a disgrace to fur trappers and collectors, and a
wasteful, worthless slaughter."
CHAPTER XLVI.
THE BEST BOOKS OF REFERENCE FOR THE TAXIDERMIST AND COLLECTOR.
It is manifestly impossible even to name under this head a tenth part of
the excellent books which might well be given place. It is also inexpedient
to include in a list, that must of necessity be brief, the names of
special works relating to the fauna of other countries than North America.
Having been from first to last a diligent user of books in the course of my
work, and ever on the alert for something new in printed word or picture
that would be of practical use, I will give here the titles of the books
that have proven of the greatest practical value to me. I must also in this
connection strongly urge the young taxidermist and collector to supply
himself with as many of these standard works as he can possibly procure. If
diligently studied they are bound to save him from many an error, and
richly repay their cost.
GENERAL ZOOLOGY AND CLASSIFICATION.
"Steele's Popular Zoology." By Professor J.W.P. Jenks. American Book
Company, New York. $1.00.
A model manual; of great value to the student because of its clearness,
conciseness, and wealth of information. Copiously and elegantly
illustrated.
"Proceedings of the Zoological Society of London;" also "Transactions."
Contains a great number of fine animal plates of much value to professional
taxidermists. The series is extensive and very costly, and is therefore
usually inaccessible except when it can be reached in some scientific
library.
ON MAMMALS.
"Illustrated Natural History: Mammals." Rev. J.G. Wood. Routledge, London,
1861. Price about $4.00. Get the original edition if possible.
This book has been of more help to me than any other I have ever found.
"Quadrupeds of North America." Audubon and Bachman.
Out of print and difficult to obtain, but very valuable.
"The Mammalia, in Word and Picture." By Carl Vogt and F. Specht. Translated
from the German by Geo. G. Chisholm. D. Appleton & Co., 1-5 Bond Street,
New York, 1890. Super royal 4to. $12.00.
This great work contains the finest illustrations of mammals, both singly
and in groups, ever published in any country. The groups represented are
wonderfully fine and life-like, and must be seen to be appreciated. No
mammal taxidermist can afford to be without this work.
ON BIRDS.
"The American Ornithologist's Union Code of Nomenclature, and Check-List of
North American Birds." L.S. Foster, 35 Pine Street, New York City. $3.00.
Indispensable to the American collector, because it is the highest
authority on the classification and nomenclature of North American birds.
Thanks to this work, it is no longer necessary to take a daily paper in
order to keep posted on the latest changes in bird nomenclature. The names
adopted by Baird (1858), Coues (1873), Ridgway (1880), and Coues (1882) are
all given. No illustrations.
"Key to North American Birds." By Dr. Elliott Coues. Estes & Lauriat,
Boston. $7.50.
This great work--indispensable to every ornithologist--consists of a
masterly treatise on systematic ornithology and the anatomy of birds, a key
by which even the tyro can learn to analyze any American bird and identify
it, and also a valuable treatise on "Field Ornithology," or
bird-collecting.
"Nomenclature of North American Birds." Robert Ridgway. Sold by F.B.
Webster, 409 Washington Street, Boston. $7.50.
Especially designed for use in the determination of species.
"Illustrated Natural History: Birds." Rev. J.G. Wood. Routledge, London,
1861. Price about $4.00. Get the original edition.
To a bird taxidermist this is the most valuable book ever published in a
single volume, because of its wealth of excellent illustrations. Of special
value in mounting strange foreign birds. Beware of the later editions.
"Studer's Birds of North America." Illustrated by Theodore Jasper. Large
royal quarto. Jacob H. Studer, New York. $25.00.
Contains 119 plates, and a colored figure of every species of North
American bird known at the date of its publication. A notable work. The
illustrations are of great value to young taxidermists as models by which
to mount birds.
"Birds of North America." J.J. Audubon.
This superb work is out of print; rare and costly. The octavo edition is to
be found in most large libraries, however, and every bird taxidermist
should at least know where the copy nearest to him is to be found, and how
to gain access to it in time of need.
"Oology of New England." E.A. Capen. Sold by Frank B. Webster, 409
Washington Street, Boston. $8.75.
This is the finest illustrated work on birds' eggs ever published in this
country.
ON REPTILES.
"Illustrated Natural History: Reptiles." Rev. J.G. Wood. Routledge, London,
1861.
Uniform with volumes on Mammals and Birds.
ON FISHES.
"American Fishes." G. Brown Goode. Standard Book Co., New York, 1888.
$5.00.
An elegant work, of convenient size. Comprehensive and eminently useful.
Fully illustrated. No collector or student of American fishes can afford to
be without it.
"The Fishery Industries of the United States." Section I. By G. Brown Goode
and Associates. 2 vols. Complete and exhaustive, both in text and plates,
and very valuable. Government publication. Sold at cost by the U.S. Fish
Commission, Washington.
"Introduction to the Study of Fishes." Albert Gunther. A. & C. Black,
Edinburgh.
ON INSECTS.
See the end of Chapter XLIV.
ON INVERTEBRATES.
"The Ocean World." Louis Figuier. Cassell & Co., New York. $2.50.
"Recent and Fossil Shells." S.P. Woodward, London. John Weale, 1856. (Apply
to Bernard Quaritch, London.)
A very handy and useful manual for the field. Many illustrations. Price
about $1.50.
"Structural and Systematic Conchology." Geo. W. Tryon. Philadelphia Academy
of Natural Sciences. $12.00.
A great work; complete, exhaustive, and richly illustrated.
FOR SUGGESTIONS OF GROUPS OF ANIMALS.
"Homes Without Hands." Rev. J.G. Wood. Longmans, Green & Co., London. Price
about $3.00.
"Mammalia in Word and Picture." Specht and Vogt, already described.
MISCELLANEOUS.
"The Sportsman's Library," as advertised by the _Forest and Stream_
Publishing Company, 318 Broadway, New York, contains an attractive and
valuable selection of books on subjects of special interest to the
sportsman, naturalist, and traveller. It includes books by specialists on
such subjects as "Camping and Trapping," "Hunting and Shooting," "Angling,"
"Boating and Yachting," "Guide-Books and Maps," "Horse," "Kennel," "Natural
History," and miscellaneous works. The list, as a whole, is an excellent
one to select from.
Of course no one with a spark of interest in hunting and the natural
history of the higher vertebrates will be without _Forest and Stream_--a
whole sportsman's and naturalist's library in itself,--or _The Field_, or
_Sports Afield_. No young ornithologist can get along without his best
friend, the _Ornithologist and Oologist_, and it would indeed be rank
heresy for the professional bird-man to ignore the stately and infallible
_Auk_.

Taxidermists: Naturalists:
Before you can properly understand the practice of Taxidermy, it will be
necessary to engage in the work, and attain efficiency by actual practice.
To accomplish the best results, it is of vital importance to have the
proper tools and materials. Poor tools and materials produce poor results.
See to it then, that you are amply provided, and before you purchase, write
us for our 24 page Catalogue, devoted entirely to =SUPPLIES FOR THE

FOREST AND STREAM
ROD AND GUN.
You may go shooting and get no game, or fishing and catch no fish; but you
cannot buy a copy of the _Forest and Stream_ (this week or next week or any
week) without finding it brimful of capital sketches of shooting and
fishing, and papers on natural history and sportsman's travel and
experiences, and discussions of yachting and canoeing. A paper for men.
_Forest and Stream_ believes in the recreation found in the haunts of deer
and grouse, and trout and bass. It believes in the common sense that calls
a halt in business drive and professional grind, for a holiday with gun,
rod, and paddle--if only afterward to drive the faster and grind the
harder. It is a journal for those who love the country and life out of
doors. It reflects the spirit and records the experiences of the great army
of outers. If you have any sympathy with these things, the _Forest and
Stream_ is just the paper you would like to have come into your home every
week. Send for a specimen copy (free on mention of this book), or $4.00 for
a year's subscription. Sold by all newsdealers.

TWO YEARS IN THE JUNGLE.
The Experiences of a Hunter and Naturalist in India,
Ceylon, the Malay Peninsula, and Borneo.
By WILLIAM T. HORNADAY,
Chief Taxidermist U.S. National Museum.
One vol., 8vo, pp. xxii. 512, two folding maps and 51 illustrations.
Price, $3.00.
THE EXPEDITION AND ITS OBJECT.
The author relates the experiences of a hunter and naturalist in India,
Ceylon, the Malay Peninsula, and Borneo; and certainly no richer
hunting-ground could be found anywhere else in the world. Mr. Hornaday is
chief taxidermist in the United States National Museum. He was formerly
connected with Professor Ward's Natural Science Museum of Rochester, N.Y.,
and his expedition to the East was in the interests of that establishment.
While his book is in some respects like such works as those which Du
Chaillu and Sir Samuel W. Baker have written to delight and interest a
multitude of readers, he has imparted a vast amount of information, a large
part of which is new and of the greatest moment to the naturalist.
Mr. Hornaday started from New York in 1876. From England he went finally
south to India, arriving at Bombay; he went across country to Benares; from
here he made an expedition to the north to Cawnpore and Agra. From Benares
he worked his way to Calcutta, journeyed down the Bay of Bengal to Madras;
southward again, he made a complete circuit of Ceylon, than to the Malay
Peninsula, and finally to Borneo, where his adventures with the oran-gutan
were met, ending his two years of fruitful and entirely successful search.
The illustrations are many, and most of them are taken from Mr. Hornaday's
own sketches. Though it may seem to be stating much, it certainly may be
truly said that a more interesting book of travel and adventures was never
published.
"Decidedly the most interesting and instructive book of travel and
adventure in the East Indies it has ever been our good fortune to
read."--_Baltimore News._
"An entertaining volume.... The author has proved his ability to write a
good book of travel."--_Morning Post_ (London).
"To the naturalist, Mr. Hornaday's book cannot but be as deeply interesting
as to the sportsman and traveller.... It deserved to be distinguished from
among the mass of books of sporting adventure."--_Melbourne Argus._
"One of the most entertaining and instructive books of its kind that has
been published."--_San Francisco Post._

Transcriber's Notes
Obvious punctuation and spelling errors repaired.
In the table "RECOMMENDATIONS IN REGARD TO HUNTING WITH THE RIFLE."
on page 14, column heading "Best distance.", had to be changed to
