"Dig yourself," said Pete Corry. "Who's going to dig a rock, I'd like to know?"

"Let Quib in, anyhow. He'll drive him out."

Abe was prying at that hole with a dead branch of a tree, and, almost while he was speaking, a great piece of the loose pudding-stone fell off and came thumping down at his feet.

"A cave, boys, a cave! Just look in!"

Quib did not wait for anybody to look in, but bounded through the opening with a shrill yelp, and Abe Selover squeezed after him.

Pete Corry felt a little nervous when he saw how dark it was, but he followed Abe; and the other boys came on as fast as the width of the hole would let them.

That is, they crept through, one boy at a time.

What surprised them was, that the moment they had crawled through that hole they could stand up straight.

"Where's the woodchuck?" asked Bob Hicks.

"Woodchuck? Why, boys, this is a regular cave," replied Abe.
