“It looks like it,” said John. “Shall we follow him?” He had turned to Mr. Button as he spoke.

“No,” said the man quickly. “The thing for us to do is to take this skiff and board the Gadabout.”

“All right,” said John eagerly. “Hadn’t we better hail the other fellows before we do that though? We are not sure that Grant and George are on board.”

“Yes, hail them,” said Mr. Button, “but don’t make much noise about it.”

John stepped forth from behind the bushes and taking his stand on the shore called, “Ahoy there! George, is that you?”

“Who’s that?” came the response from the motor-boat.

“Fred and I are here,” responded John.

“Who are ‘I’?” laughingly came from some one on board the Gadabout.

“I guess you know who we are. That’s you, isn’t it, George?”

“It’s Grant and I.”
