"And we'll find out a few things, if we have to knock those fellows on the head."

The thought was so exhilarating that the warm blood was again driven through their veins, and the numbness seemed in a measure to go out of their chilled bodies. Nothing is so reviving as hope. And hope was theirs again. The raft drifted so slowly and Bart was so eager that he wanted to leap into the sea and swim to the vessel.

"Let us save our strength," was Merriwell's advice. "We are going straight there. We will probably need all the strength we have."

"I see only one man. He is pottering about near the cabin."

"The other is aboard somewhere. And you noticed that dog? If he puts up a fight, too, I've an idea that he will be worse than either of the men."

The progress of the little raft was tantalizingly slow, but it moved steadily, and after the sun had set and while the darkness was gathering on that great expanse of water, it swung close in under the stern of the sloop. Not a sound was heard aboard of her as she lazily lifted and rolled on the heaving swell.

Frank took his shoes in one hand, but thought it not well to burden himself with the extra coat.

"Now!" he whispered. "Let the raft go. We can cut that boat loose if we have to trust to the sea again. Follow me!"

Then he slipped silently into the sea, Hodge imitating his example. Softly swimming round to the bow, Frank got hold of a chain that ran down from the bowsprit.

"Here," he softly whispered. "Lay hold of this, and come right up after me."
