"And pull down several tons of dirt and rock on your head," said Dick. "Better go slow. We already know how treacherous these holes are. You'll get out of one by getting into another that's worse."

"I brought a lariat along," said Sam.

"A lariat?" queried the others.

"Sure,—the one I bought when we were out west. I thought we might use it for climbing purposes. It is light but strong, and we can lasso a tree or stump up there with it."

"Hurrah! Sam has solved the problem of how the Rover boys shall rise in the world!" exclaimed Tom, gaily. "Sam, try your skill by all means."

"Show me the tree or stump and I will," answered his brother readily.

As well as they were able, they crawled from one part of the hole to a spot that was somewhat higher. Then they found a projecting rock above them and Sam threw the noose of his lariat over this.

"Will it hold?" queried Dick. "You don't want to try to climb up and fall."

With caution Sam pulled on the lariat. It held, and he went up hand over hand, for he was a fair athlete. Then his brothers followed. They now stood on a ledge of rock, and the top of the hole was still twelve feet above them.

"There is a small tree, Sam," said Tom, looking upward. "If you can lasso that I think we'll be all right."
