The babies scampered on to the end of the main tunnel. There the ground happened to be soft enough for their little claws. They crowded against one another, and squeaked and twitched their short tails impatiently. Their pink snouts were already bending and twisting in eagerness to be a-digging.

The fattest little fellow was in such a hurry to begin that he did not wait to be told. He nosed along the wall till he found a good place to start. Then planting his small hind-feet down flat, to brace himself, he set his tough snout against the dirt and pushed as hard as he could. At the same time he dug his claws into the wall and shovelled away with both his big broad hands.

There they went—the five babies—digging five little tunnels in five different directions. The dirt flew thick and fast as they shovelled it out and tossed it aside. But the specks of eyes were safely hidden under the fur, and the invisible ears and nostrils were kept closely covered too. When the dirt clung to their satiny gray fur they shook it off clean with a quick shrug of the skin. The hairs of the fur grew straight out, and so it made no difference whether it was rubbed one way or another. It was never bristly or rough.

It must have been fun to go scrambling through earth almost as birds fly through air or fishes swim through water. The moles had such tough snouts and strong arms and powerful hands that they could burrow better than any of the other mammals.

One little mole burrowed on till his arms were so tired that he gave it up. He crept backward down his new tunnel to the spot where the old mother was waiting. Another kept on digging faster and faster till he ran his pink snout bump against a stone, and almost made it bleed. A third pushed on and on till he reached a patch of slimy mud that caved in over his back and sent his feet slipping and sprawling. The fourth dug till he came plump upon a fat white grub curled among some roots of grass. The little mole gave a jump and gobbled it down quick as a wink.

The fattest baby burrowed farther and farther till he felt the soil crumbling above him. Something warm was shining on his gray fur. He lifted his head and poked his long snout up into the sunlight. He blinked his twinkling, tiny eyes and sniffed the strange fresh air. But he stayed there only for a minute, because he did not like it the least bit. The light dazzled him, and the warmth dried his cool, pink hands and made his head ache and his snout twitch uneasily. So after that one disagreeable minute he turned and kicked up his little hind-feet as he dived back into the moist, cool, dark, delightful places underground.

After this first lesson in digging the five young moles were running in and out of the nursery every few hours, night and day. It was easy enough to burrow away in search of the stupid white grubs or the beetles lying sleepy and still in the soil; but it was harder and much more exciting to hunt earthworms, because they always tried to wriggle off as fast as they could go.

Then how the dirt flew as the little hunter burrowed madly in pursuit! Now in this direction, now in that, he chased, pushing with his snout and tearing with his claws. Once in a while he stopped quiet to listen and feel the ground for the faint quivering caused by the worm in its squirming hither and thither.

An hour or so of such lively work was enough to tire even a stout young mole. After eating what he had caught, sometimes he ran back to take a nap on the soft bed in the nursery. Sometimes he lay down in the main tunnel to rest; but that was not so pleasant, for it seemed as if one or another of his brothers and sisters was forever trying to scramble over him.

The busiest time for hunting was at night, or in the early morning, because then the worms began to move about after lying quiet all day. In dry weather the worms went deeper into the ground to find moisture. In wet weather they wriggled toward the surface, swallowing bits of dirt as they went. The little moles liked rain best because it was much easier to push through the light soil above than to tunnel through the hard ground below.
