ehension that thrilled every other member of the party.

"I don't know," his father replied; "but I'm going to find out pretty
quick. You boys stay here with the prisoner. I'm going down there to
investigate."

With this announcement, he drew his automatic for ready use and began to
descend the steps they had fashioned in the stony hill before
establishing their camp on Friday Island.

CHAPTER XXVII

Chased Out

The investigation did not take long. The boys watched Mr. Perry as he
crossed the moonlit deck of the Catwhisker and entered the cabin. A few
minutes later he returned on the deck and with him were two men, whom the
observers on shore recognized as Mr. Baker and the Canadian officer. Then
Mr. Perry called out:

"Come on down here, boys."

A minute later they were on board the yacht with their prisoner. Cub, the
most impatient of their number, was first to speak.

"What's the matter?" he asked.

"Matter enough," growled the officer. "Those scoundrels outwitted us,

woke up I was in a pitch dark stateroom, with the door locked. Luckily my
searchlight had not been taken out of my pocket, and soon I had the place
well enough lighted to determine where I was. I also found something
else; I found Mr. Buckley in the same condition that I had been
in--unconscious. Mr. Buckley can tell you the rest."

"There's absolutely nothing for me to tell," Mr. Buckley replied, "I went
to sleep on the cot in the cabin and woke up with a headache in the
stateroom. Mr. Baker was working over me as if I'd been shell-shocked on
the battlefield. I think we both were sandbagged, for there were no
bruises on our heads. We were locked in and probably would have been
driven to the necessity of breaking the door open if Mr. Perry hadn't
come when he did and let us out."

"I found both the s
