t tell me now where he is?"

"I--I--can't," faltered the other.

"Don't you know?"

"No, but I can find out."

Hal was sure the fellow was lying, and he looked at him with accusing
penetration.

"You'll have to let me do it my own way," the Canadian youth added
stubbornly.

Realizing that he could make no further progress with the prisoner at
present, and fearing that it might not be wise to disclose what more he
had learned by listening to the wireless messages the hazer had just
sent, Hal returned to the deck and recounted his experience in the cabin
to his companions. All were assembled at the pilot house when he gave
his recital.

"This is important," said Mr. Buckley when the account was finished. "I'm
glad you didn't disclose to him the fact that you suspect anything is
going on of interest to the Canadian government. He won't be on his guard
so much perhaps as he would be if you had put all your cards on the
table. By the way, everything seems to be happening in our favor right
now. There's a Canadian revenue boat over there. Let's run over that way
and hail it."

The boat in question was somewhat larger than the Catwhisker and looked
as if it might give the yacht a merry race if the two were matched for a
test of speed. She was 300 yards distant and in a few minutes the evicted
Friday Islanders had run up within short hailing distance of her. Then
Buckley gave a signal, which was recognized, and the two boats were
brought close together. A short conversation between Buckley and the
commander of the revenue boat was sufficient to acquaint the latter with
the situation, and he promised to remain in the vicinity in order that he
might come speedily to the aid of the Catwhisker when needed.

Then began the work of careful examination of the Friday Island group
with binoculars. The yacht was only a few hundred yards from these
islands when the Canadian revenue cutter was sighted. After arrangements
for co-operation had been made with the commander of this boat, the
Catwhisker began to move slowly around the group, while Mr. Perry and Mr.
Buckley examined every detail of their littoral features with strong
glasses. Cub was at the wheel, and Mr. Baker, Bud, Hal and Max stood near
the two men with the glasses, eagerly waiting for significant results.

"I wonder if this is to be the finishing stroke," said Bud, addressing
the two boys near him.

Mr. Perry overheard the "wonder" and replied:

"I am confide
