Popular Science Department A
DEPARTMENT OF INTEREST TO YOUNG AND OLD
EDITED AND ILLUSTRATED BY PROFESSOR A. HYATT VERRILL
Digitized by Doug Frizzle,

NEARLY every boy wishes to
have a collection of some sort, and
as so many boys have written me to ask how to collect, preserve, classify, and
keep insects, birds' eggs, nests, or other
objects, that for the present I am
going to devote this department to telling you just how you should do all these things. If you are really interested in nature
and popular science and wish to collect specimens with, the
object of learning something, you
will be interested in finding out more about it, but if you have collected a
few odds and ends and have the idea
of collecting merely as a fad, you will not care one way or the other,
and the directions will be useless
to you. As a rule, several boys can start a collection, and that is far better
than one started by a single boy, for each usually has some
special line in which he is interested or with which he is more or less
familiar. The first step, therefore,
is to talk to your friends and find out how many will join in making a
systematic collection and in looking after it. Having selected the "directors" of your museum, you should
find just what each boy is interested in. From
these select one interested in
birds, another in minerals, another in plants and trees, and another in insects, and if possible, others interested in reptiles, fishes and animals. Of
course it is sometimes impossible to
do this, for some boys may all be interested
in the same subjects, but in such
cases two or more departments may be assigned to one boy. The boys thus
selected should be appointed "curators" of their
respective departments, and should have full charge of the
collections under their direction.
Any specimens of one thing, found by a curator of another
department, should be brought in and turned over to the
proper curator. In this way much larger and more complete
collections will be obtained than by each boy confining his attention to one
subject; for it is a fact that while you are looking for plants you will find
lots of objects you are not looking for, in the
way of insects, minerals, etc., and the
butterfly-hunter will no doubt run against many interesting plants, birds and
reptiles. Before the collections are
begun, however, some preparation for
their preservation and exhibition
should be made. Doubtless one or more of your directors will have a spare room or outbuilding which will do for a museum. This
room should have all useless
furniture and other material
removed, and should be used solely as a museum and workroom.
The workroom, or preparatory room, should be partitioned off and used in assorting,
preparing and working up your collections. It should contain tables, chairs,
shelves for books and specimens, tools, materials, unclassified specimen boxes,
and all other material used in
making and preparing the
collections.
For the
museum proper you must make and put up shelves, or cases, or both. Cases with
glass doors are the best, and you
can probably manage to get at least a few by using a little ingenuity and
trouble. Old window sash can be used for the
fronts, or you can make your own doors and fit glass to them.
If you cannot manage to make real wall cases, you can at least make boxes to
fit the shelves, and put single
glass covers to these for your rarer
and more fragile specimens. Minerals, woods, stuffed birds and animals, and
alcoholic specimens do not require cases, but may be placed on open shelves.
Fit the shelves to all portions of the room
around the sides and, if large
enough, additional cases or shelves may be placed in the
centre of the room on a bench or table. One lot of shelves or cases
should be reserved for each department, and each of these
plainly and neatly labeled with the
class of specimens intended for it. Thus label one lot VERTEBRATE ANIMALS, another INVERTEBRATES, another
INSECTS, a fourth MINERALS, a fifth BOTANICAL SPECIMENS, and another BIRDS AND BIRDS' NESTS. Under each label print the name of the
curator and a list of the divisions
of each group under his direction. For example, under INVERTEBRATES the name of the
curator should be placed, and below this a list of the
divisions represented in the
collection (if complete), as
"Mollusca," "Worms,"
"Crustaceans," "Sponges," etc. Leave a blank space to be
filled in, as additional divisions are collected and added to the collection. In addition to these large labels there
should be individual labels for each specimen. If one of the
boys owns a printing press or typewriter, these
may be made small and neat. They should be printed in plain, clear type, and
should be arranged as follows:
* Common
Name ................... *
* Scientific
Name................... *
* Locality .........................
*
* No............. Sex..............
*
* Donor ...........................
*
Each curator should be
provided with a blank book, in which the
name, number, sex, locality, and name of donor (person giving or collecting the specimen) should be written as soon as the specimen is obtained, also the date on which it was received or obtained, and
any remarks in regard to its habits, colors in life, etc. The sex should be
designated by the marks ‡ for male and * for female.
Each curator should keep a separate set of numbers for his own department, and
it will then be very easy to keep
track of your collections and look up any interesting points in regard to them. Moreover, each specimen should be marked with
a small number corresponding to that in the
books, so that in case of loss of labels the
specimen may be identified and relabeled. These numbers should be as small as
possible, and may be placed directly on the
specimen, as in the case of woods
and minerals, or written on the
stand or pedestal, as in case of birds and mounted animals. Alcoholic specimens
should have the number written on
tough paper with lead pencil, and placed in the
bottle with them.
Of course, before beginning
your museum, you must make some preparations
for taking care of the specimens. If
any of the curators have already
collected anything, they will no
doubt be provided with instruments and materials for their
own use, and these may be used in the interests of the
museum. The insect curator should have nets, pins, collecting boxes, etc., and
so with each of the other curators. Later I shall describe how to collect
and preserve the specimens in each
group separately, and will then give
a detailed list of the really
necessary articles required with a description of the
use and the cost of each.
Very likely your school
teachers may be interested in your museum, for such collections when property
made are of great value and interest in school work, and if they take up the
matter they can help you a great
deal. You will also find that your boy and girl friends—as well as many grown-ups—will
be interested in your museum, and will constantly bring in new and rare
specimens as well as many duplicates. Such should always be kept and preserved,
for although duplicates should not be exhibited they
are always valuable in case of injury or loss of a specimen, and may often be
exchanged for valuable things from other localities or even sold for good cash prices to
collectors and dealers.
You may at first think that
your museum shelves look bare and will be hard to fill, but you will be
surprised to find how rapidly they
will fill up, and that lack of space will be a greater problem than lack of
specimens. No matter how poor a specimen may be, it should be kept and
exhibited until a better one is secured, when it should be replaced. Aim to
have every museum specimen as perfect as possible, however, and if old,
preserved specimens of any sort are presented to your museum, be sure they are thoroughly cleaned and free from moths and similar pests before placing them among your other
specimens. In fact your greatest difficulty will be in protecting your
specimens from dirt and museum
pests. Dust always seems to be thicker as soon as you have valuable specimens
to look after, and moths and beetles seem to know by instinct when a collection
is within their reach. To prevent
moths as much as possible it is wise to paint or whitewash all the walls and shelves of your museum before placing
anything within, and a thorough fumigation with sulphur is also wise. In
addition, place moth-balls or napthaline-flakes on each shelf and in each case,
for as long as your museum smells strongly of napthaline you are pretty safe.
Moths always show their presence by
little piles of dust, fur, or feathers,
beneath the object they infest, and as soon as any such signs are seen,
remove the specimen, dose it with
benzine or naptha and dry in a closed box or chest. Never use sulphur in any
form where specimens are, as it ruins the
colors. Although you cannot collect very many things during the winter months, yet you may spend a great deal of
time in preparing your museum, labels, and any specimens you have on hand,
while the cold weather is just the
time to collect specimens of woods and minerals which later on would be
neglected, owing to the more
attractive things among the birds,
plants, and insects.
A complete
collection of the native woods of
your locality is always interesting and valuable, as well as instructive. Few
of us stop to realize the variety of
native woods growing in our neighborhood and fewer still are able to recognize
many of our commonest woods when we
see them. Not many of us know the differences of the
various tree-barks or how the grain
runs in the natural trunk. Wood
collections are the easiest to make,
and during the winter evenings all the curators and your friends can busy themselves in preparing, classifying, and labeling the specimens. Before collecting woods you should be
absolutely sure that you know the
trees from which the specimen is to be taken. If in any doubt, look
for old leaves clinging to the
branches, for fallen leaves beneath, or for the
fruit, nut, or berry the tree bears.
If after due care you are still doubtful of your tree, ask some lumberman or farmer. Although the best specimens are obtained from live trees, old wood-piles often contain splendid
specimens and, usually, the farmer
or woodsman who cut the trees can
identify anything you do not know.
The wood specimens should all
be of nearly one size, and as pieces too small or too large are apt to be more
or less peculiar, an average size is best. By selecting straight, well-grown
limbs about three inches in diameter, a good average will be obtained,
although, of course, at times you will be obliged to take smaller-sized limbs
or pieces split from the main trunk.
Cut the
limb carefully, leaving the bark on,
and, keep a piece about a foot in length. As soon as cut this should be
numbered and marked with the name.
This is best done by whittling off a little bark at one end and writing
directly on the wood with a soft
carpenter's pencil. The pieces of wood thus collected should be placed in a
dry, warm place to season and should be turned over occasionally to dry them evenly.
When thoroughly dry, saw off
one end diagonally with a fine-toothed
saw at an angle of about forty-five degrees. A mitre box should be used, as it
insures all the pieces being alike.
Next, with a draw-knife and plane, work down the
side (on the short side of cut)
until the exact centre of the piece is reached. Your specimen will now be a
half-round piece of wood with one end cut at an angle. Now, smooth off a little
of the right-hand side to show the grain and cut off the
piece squarely and smoothly about six inches from
the sloping end. All the specimens should be cut alike and to the same size, and care should be taken not to scar
or break the bark. In case it should
loosen or break, glue it firmly in place again, as the
preservation of the bark is
important. The specimen should now have all the
surfaces of the wood carefully smoothed and sandpapered to a fine finish. When this is done
a small portion (about two inches) from
the base should be marked off on
each piece, and this space given a coat of good varnish. Your specimen will
thus show the bark, a cross section,
a heart section, and a quarter section of the
wood in their natural state in
addition to the board and quarter
section appearance when varnished.
In arranging these wood specimens they
should be set up on the square end
and slightly turned to one side so that the bark, as well as all the various wood-sections, are easily seen. It is a
good plan to mount each specimen on a piece of stiff cardboard with a tack
driven up from below. On this
cardboard you should mount the
pressed leaf and the nut, or fruit,
of the tree from
which the wood was taken. The label
of the whole may then be placed on the
same card, or placed above and behind it, as desired. The fruits or nuts of
most trees require very little preparation. They should merely be carefully
dried and when dry any parts that become
loosened, or drop off, should be glued in place. Many seeds and nuts will keep
on ripening after drying, and to prevent their
natural bursting apart it is best to soak them
in alcohol or formaldehyde solution (2 per cent) for a few days before drying.
Dipping in boiling water will answer the
same purpose. The leaves are simply pressed between blotters under a heavy
weight and when thoroughly dry may be glued to the
card.
If any of the curators or their
friends have cameras, a very attractive feature of the
collection will be a series of neatly-mounted photographs showing the various trees as they
appear in winter, after the leaves
have fallen. Trees, to show this, should be carefully selected for perfection
of growth and form; they should also
be isolated specimens growing by themselves
in open fields, or in clearings from
which the other
trees have been cut. The pictures should be clear and sharp and the "harder" the
better, as the idea is to show the shape and branching form of the tree without attempting an artistic picture. The
photographs should be placed either
behind the specimens of wood, or
hung above them, and as far as
possible each specimen of wood should be accompanied
by the photograph of a tree of the same kind.
Quite often the leaves may be difficult to preserve, or may be
of such a character as to prevent placing them
on exhibition with the wood. In such
cases the leaves themselves may be replaced by either solar prints or "autograms" of the leaves. The solar prints are easily made with either blue-print, or printing-out paper, and the only materials required for the former are a printing frame, glass for the frame, and the
prepared paper. Place the leaf to be
printed face up on the glass, lay the printing paper face down upon it, close the frame and expose to direct sunlight until the paper around the
leaf has grown to its deepest shade. Wash thoroughly in cold water and a beautiful
print of the leaf, in white on a
rich, blue ground will result. If printed deep enough, each tiny vein will show
and the print has the great advantage over the
real leaf of never decaying, breaking, or curling. Printing-out-paper
leaf-prints are made in the same
way, but must be toned and fixed like a regular photograph. For those who are
unable to make use of either of the above methods, the
"autogram" prints are excellent, and are in many ways far better than
the solar prints. Autograms require
no special materials; a rubber roller such as is used in mounting photographs,
a little printer's ink, or some
tubes of oil colors and white paper only are required. Place a fresh leaf on a
sheet of paper, or card, and brush the
under surface smoothly and evenly with a coating of the
ink or paint. Do not get it too thick, using only enough to stick to all
portions of the leaf. Place the inked surface of the
leaf on a piece of clean paper or card; cover it with a sheet of soft paper;
hold the stem in place by one finger
pressed upon it on the covering
paper, and run the rubber roller
firmly over the whole. Now, lift off
the cover paper and the leaf and you will find that a perfect and
beautiful impression has been printed upon the
paper beneath, exactly as an engraving or type is printed. If you have a
letter-press in the house even more
perfect prints may be obtained by its use. Care should be taken that the paper on which print is to be made, rests upon a
level, rather soft surface such as a
pile of old newspapers or a thick magazine, and be careful not to smudge when
placing or removing the leaf itself.
You will be surprised to find what a fine addition the
wood collection will make to your museum, and if you are in earnest and are
industrious, your collection of woods will be pretty complete
by the time the
next issue of THE AMERICAN BOY reaches you, with directions for preparing your
collection of rocks, minerals and Indian relics.
