“All right,” Cub assented.  “What is the next step for us to take?”

“Find out who the fellows are that hazed Hal’s cousin.”  Bud replied.

“Yes, that’s a good suggestion, though it’ll probably require several steps to gain that information.  Still, you’re not looking so far ahead, when you propose that move, as to be unable to see your first step.”

“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 rescue.”

These and subsequent proceedings, in furtherance of the plan outlined “over the wireless” by Hal, took considerable time, but at last the situation was made clear to Mr. Baker, who announced his intention to start on a search for his son at once.  Meanwhile Bud and Cub listened-in eagerly and translated the code messages for Mr. Perry.
