"No. He followed me over to the other side of the island, and then he started to return by coming straight back through the woods. That is all I know. I am here to learn if he returned safely. If he did, I intended to warn him that his life was in danger if he should go about the island alone. You must see that I am serious now."

"Oh, yes, we see!" came scornfully from Diamond. "It is too thin! It will not work, Mr. Cooler. You know too much not to know more. If you wish to keep your skin whole, just lead us straight to Frank Merriwell—that's all!"

"I can't. I would do it if I could. But I give you my word to do my best to save him if he is in trouble. That is the best I can do."

Diamond's anger caused him to lose his head so that he threatened the old man with his fist. He quickly

realized what he was doing, however, and, with an air of apology, he cried:

"If you keep it up, you will lead me to do something of which I shall be ashamed. You can't fool us, old man. We have you foul, and we'll never let up on you till you lead us to Frank Merriwell. We are young, but you will find we can keep a pledge like men."

In truth, Cooler seemed in earnest as he said:

"Young gentleman, you wrong me very much. I am ready to go with you and do what I can to help find Mr. Merriwell, but that is all I can do. It will be better if you will let me go alone. I shall be able to work alone far better."

"Oh, yes," sneered Hodge. "You think we are fools! No, we go with you."

"All right. I am ready."
