6. Then it makes tunnels all around, not any one leading straight up to the nest. In the picture we see the mole's nest and the tunnels leading to it. The mole drinks a great deal, and in its tunnels it digs wells where it can go down and find water.
7. In the summer it keeps near the top of the ground; but in winter it digs down deeper, to find grubs, and because it is warmer.
8. In digging under ground, the mole destroys the roots of grass and plants, and does some damage; but it does much more good, by destroying the grubs which live on the roots of plants.
LESSON XLIII.
ABOUT THE PORCUPINE.
1. We find in the woods a curious animal called a hedgehog, but which is really a porcupine. The hedgehog is found in Europe, and lives upon insects; the porcupine lives in quite a different way.
2. The porcupine is a little larger than the rabbit. It has short legs, sharp claws, and a short, broad tail. Like the rabbit, it has chisel-teeth for gnawing.
