"Yes, I do," said Frank; "I see plenty of old friends. I know every stick of timber about here, for I passed three of the pleasantest weeks of my life in this very ravine. You have heard Dick and Bob speak of the Old Bear's Hole, haven't you? Come with me, and I will show it to you."

Frank crossed the creek and began pulling aside the bushes at the base of the cliff, searching for the entrance to the cave. Dick had told him that more than one sharp-eyed Comanche had looked for it in vain, and for a long time Frank thought he should meet with no better success; but at last he discovered the entrance by stepping into it accidentally. The mouth of the passage was filled with leaves, which had effectually concealed it from his view.

"The cave must be a mile or two below, isn't it?" asked Adam, gazing dubiously at the dark opening.

"No; it is above ground altogether, and is inside this rock," replied Frank, pointing to the cliff. "But the question is, Shall we use it, now that we have found it? Do you suppose that Black Bill and his friends are in pursuit of us?"

"Of course they are. They won't give us up so easily."

"But we have taken a great deal of pains to conceal our trail, and they may not be able to follow it."

"Don't you believe it," replied Adam, with a laugh. "Those men's eyes are as sharp as a hound's nose. If they can track an Indian when he is doing his best to cover up his trail, they can surely follow us. We are not done with them yet."

"Then I propose that we sleep in the Old Bear's Hole. I can't travel any farther to-night, and I should feel much safer in the cave than I should if we camped in the open air. We can't get along without some supper, and we must have a fire to cook it; and that might attract the attention of the outlaws if they should happen to be in the neighborhood."

The matter was settled without any further debate, and the boys began to busy themselves in collecting a supply of pine-knots to serve as torches. This done, Adam lighted one of them with his flint and steel, and handed it to Frank, who backed down into the opening; but, to his friend's surprise, he came out of it again much more quickly than he had gone in.

"I have just thought of something," said he, in reply to Adam's inquiring look. "The first night we camped here, while we were on our way to California, Dick Lewis went into the cave and found that a grizzly bear had taken possession of it. He had a terrible fight with the animal, and was so badly clawed up that his most intimate friend would not have recognized him. There may be a bear in there now for all we know."
