"Why not try to get in touch with some amateur in Cousin Alvin's home
town by wireless?" Hal suggested.

"That's the very thing I was in hope one of you would propose," Mr. Perry
replied. "You boys haven't by any means exhausted the possibilities of
your radio outfit."

"We have no Canadian call book," said Hal, "but perhaps I can induce one
of the amateurs we've been talking with to look up the call of one or
more amateurs in Port Hope and give them to me."

Without more ado, he swung the switch into sending position and began to
call the amateur who had given them the information that had enabled them
to locate Friday Island. Success rewarded his efforts almost immediately.
The curiosity of the Rockport amateur, however, had to be satisfied
before further service could be had from him. This Hal did with due
patience and speed, reciting their experiences since their arrival at the
island. Meanwhile the Canadian consulted his call book, and was ready
with the desired information by the time his very excusable curiosity had
been satisfied. He supplied Hal with two Port Hope calls, together with
their wave lengths.

Then began the task of getting into communication with the Port Hope
amateurs. Hal sent the call of each of them a score or more of times, but
got no answer from either. At last, however, another Port Hope amateur,
who chanced to be listening in, answered for them. He informed Hal that
the sending outfit of one of these Port Hope boys was out of working
order and the other amateur was out of town. Then the operator on Friday
Island put the following questions to him:

"Do you know Alvin Baker?"

"Yes," was the reply.

"Is he at home?" Hal continued.

"I think not. He is at college."

"I am his cousin, Hal Stone, from Oswego, New York. I am with some
friends on an island in the St. Lawrence River. I have learned that Alvin
is in trouble. He was hazed by some sophomores, who left him alone on an
island in the river. We found the island, but Alvin had been spirited
away and is probably being held prisoner by them. This hazing gang seems
to consist of some pretty rough characters. I want to get in touch with
my uncle, Alvin's father."

"I will call your uncle on the telephone and tell him what you say," the
Port Hope amateur dot-and-dashed in reply.

"Ask him to come over to your house, and tell him I will explain
everything to him through you, and then perhaps he can form a plan for
his son's
