"Yes, and yonder is another vessel," returned Sam, as he pointed the glass in the direction. "That must be the Josephine." And then the two youths shouted the news to those below.

After that the boys watched the progress of the steam yacht with interest, keeping those below informed of all that was going on. They saw the Rainbow draw closer to the other vessel, and saw the small boat leave the steam yacht.

"Four men are rowing to the other vessel," announced Tom. "We can't make out who they are."

They saw the four men board the other vessel and disappear, presumably into the cabin. Then came a wait of over half an hour.

"This is getting tiresome," said Tom.

"You can go below if you want to," answered Dick, who had come up, followed by Songbird.

Tom descended to the ground and Sam followed him. They had just done this when there came a cry from Dick:

"Two boats are putting off from that other vessel! Each of them is filled with men!"

"Are they coming ashore or going to my yacht?" demanded Captain
Barforth.

"They are heading for the yacht!"
