MOUNTS—After having cleaned your specimen, mount it so that it
ean be seen to its best advantage, label it, and number it for quick
reference.
The collection should be kept in uniform boxes or mounts. An average size mount is 2x3 inches, having a place for the label on the bottom. If a square box is used, place the label underneath the mineral.
Over the label place a sheet of cellophane. This keeps your label clean.
For specimens that are smaller than the average 2x2 inches, a giass
vial with a cork is suggested. This shows the mineral off at a better
advantage. If the specimen is very small insert a small quantity of
cotton in the bottle.
Molded mounts made of Textone, concrete, or plaster of paris are
ideal for large collections, or, room permitting, it is advantageous to
display them on a shelf. Wood, metal, or heavy rubber boxes or cans
are easily converted into forms for casting specimen mounts.
NUMBERING THE SPECIMENS—AI specimens should be numbered so that they correspond to the number in your record book as
well as to the label on the mount. Small round stickers of % inch
diameter are best for this purpose. Small squares of adhesive tape, with
the numbers in black ink, have also been used to advantage.
LABELS—On each mount containing a specimen a label should be
placed, thus enabling you to tell at a glance the name of the mineral,
the species, and the locality in which it usually occurs. If the collection is fairly large, a printed label, like the sample on page 3, can be
obtained at a small cost.
Wl. CHEMISTRY
Before we begin our experiments it would be helpful to know a little
about Chemistry. What is Chemistry? Without doubt it is one of tne
most fascinating of all sciences. Indeed, there are more wonders in
Chemistry than in the most fantastic story ever written. It produces
spectacular results, carries on a continuous warfare against discase,
aids the police in capturing criminals, drives the gigantic machines of
industry and commerce, supplies us with the necessities and luxuries
of life, and plays an important part in our ordinary everyday life.
Light a cigarette, blow out a candle, snap a picture, breathe—and you
are performing chemical actions,
ELEMENTS—It perhaps comes somewhat as a surprise to you to
ledrn that the universe and every material substance is made up of only
96 different elements. An element is a substance that cannot be broken down into other substances by chemical action. It is a relatively
simple form or unit which enters variously into a complex substance,
By way of example, we may say that bricks are the elements of a wall,
cells are the elements of living bodies. From these 96 different elements
we obtain the hundreds of thousands of things produced by nature,
industry and science.
COMPOUNDS—When two or more elements combine chemically the
resultant substance is known as a compound. Every definite chemical
compound always contains the same elements, united in the same
