From what animals do we get furs?

What is silk?

[Illustration: THE SILKWORM AND MOTH.]

Silk is made by little worms called silkworms. When the worm is fully
grown, it spins round itself a small ball of silk, called a cocoon. If
this cocoon were left to itself, the worm would change to a moth, and
the moth would eat its way out of this little house. But this, of
course, would cut the little threads and spoil the silk. As soon,
therefore, as the cocoon is made, it is put into hot water to kill the
worm. In this way the silk is saved.

What animal shows the most affection for his master?

Mention some kinds of dogs.

You may have seen a dog called the St. Bernard. He is large, with long
curly hair. In the Alps mountains, where traveling is dangerous, the St.
