usins. If you look
at them carefully in the pictures on pages 103 and 109 you will see
which is the antelope and which is the deer--just as you can tell a
sheep from a goat.

First see the picture on page 103. These are _antelope_. Look at the
horns carefully. They are something like a cow's horns; only, a
cow's horns are sometimes bent and twisted in different ways. But the
antelope's horns point upward, and are much longer than a cow's horns.
They sometimes look almost like a pair of long and thick spikes,
pointed at the top.

Now look at the picture on page 109. These are _deer_. Look at the
horns carefully--only, they are not called horns when the animal is a
deer, but _antlers_, which is a special name. So take a good look at
the deer's antlers. There are two of them, and they grow from the top
of his head, like the antelope's horns.

But look again. The antlers _start_ from the head as _two_ spikes, but
higher up each antler branches out into _many_ parts. In fact, near
the top each antler looks something like the branches of a small tree
without leaves.

So now you can always tell which is an antelope and which is a deer:
the antelope's horns have no branches, but the deer's antlers have
many branches.

_Horns and Antlers Different in Three Ways_

The antelope's horns and the deer's antlers are also different in
other ways, which you cannot see in the pictures. So I shall tell you
about them:

1. The antelope's horns are _hollow_ inside, and made of the same kind
of thing as the _hoofs_ or _nails_ of an animal, only they are thicker
and harder. But a deer's antlers are _solid_, and made of _bone_.

2. Both the Papas and the Mammas among antelopes have horns. But among
most kinds of deer, only the Papas have the antlers; the Mammas have
none.

3. Among antelopes, when once the Papas and the Mammas have grown
their horns, they keep them always. But among deer, the Papas throw
away their antlers every year, and grow _new ones_. That seems very
wonderful! I shall tell you more about it soon.

But now I shall tell you, little by little, all the wonderful things
the deer and the antelope can do. I shall begin with the deer, as
there are many kinds of deer in America.

Of course, in America there are not such wild jungles as in countries
which are hot all the year round. Still, there are many places in
