“Now, Wash Crosby, you stop rowing, too!” went on Jerry.

“Think you are boss, eh?” sneered Crosby.

“I am. Up with the oar!”

Crosby hesitated, and then his oar went up beside Si’s. The others became badly frightened and also stopped rowing. In a moment more the hermit’s craft was beside the big row-boat.

The Rockpointers gazed at the white-haired man in astonishment. They wanted to know who he was, but just then had other matters to attend to.

“You think you own the earth when you have a gun!” howled Si Peters to Jerry.

“We’re on top, that is certain,” responded our hero. “Say, Harry, supposing we get on the yacht and make them row us back to the island?”

“Not much!” growled Wash Crosby.

“Just the thing!” cried Harry.

Still keeping the Peters’ crowd under guard, Jerry and his friends boarded the yacht.
