“Give him up?”

“Exactly. Come up alongside and let him jump on board of the yacht.”

“That’s as cool as a cake of ice!” cried Jerry. “You want everything, don’t you?”

“We are going to get square with you, Jerry Upton!” put in Wash Crosby.

“Let us pull away as fast as we can,” whispered Harry. “Those chaps mean trouble.”

Then Si Peters ran out to the jib of the yacht.

“Stop!” he commanded. “Pull another yard and you’ll be sorry for it.”
