Little Mrs. Cockroach has smelled the dainty morsel, and, as soon as it
is dark, out she will run, her feelers moving eagerly this way and that,
until she has found it.

Yes, May, insects also feel with their antennæ. That is why the antennæ
are often called "feelers."

There are other dots on the segments that are sensitive to touch.
Sometimes there are tiny hairs on the antennæ, also sensitive to touch.

The little fellows feel and smell, yes, and oftentimes _hear_ with their
antennæ.

Many insects have spots sensitive to sound on the antennæ.

Yes, indeed, May, it is wonderful that such tiny threads as an insect's
antennæ should hold so many kinds of sensitive spots.

An insect's antennæ are among the most wonderful things in the world.

And _I_ think a cockroach, in spite of its bad reputation, is a very
wonderful little fellow.

What is that, May? Our cockroach is drawing one of its antennæ through
its mouth?

Ah, yes, see it clean its antenna, children.
