The Radio Boys in the Thousand Islands Part 4

Preparation for the test was simple and quickly made. The loop aerial, a collapsible affair, was set up in the cabin and connected in such manner that it could be used for receiving simultaneously with the use of the outside aerial for sending.

While Cub was thus occupied, Mr. Perry set a hasty supper of prepared foods on the table and "ate a bite". Then he returned to the chart and wheel house and relieved Hal, sending the latter back to the cabin for his meal and for further radio consultation with the other boys.

CHAPTER V

A Baffling Situation

The compa.s.s worked admirably. Although the principle of the affair was very simple, Hal must be given credit for having done his work well.

So satisfactory did the device prove from the moment when it began to take messages from the "island prisoner", that all on board the Catwhisker became hopeful of success before sun-down. "V A X" kept a stream of waves leaping from his aerial for their guidance and the motor boat chug-chugged along like a hunting hound made more and more eager by the increasing excitement of the hunt.

"I wonder what's become of the fellow who tried to head us off," remarked Hal as he left the supper table and prepared to relieve Cub at the wireless. "You haven't heard anything from him, have you?"

"No, not a thing all day," Cub replied. "I guess we've tired him out. Did you get anything from him, Bud?"

"Not a s.h.i.+ver of the wires," answered the latter.

"Maybe he's given us up as hopeless easy marks," Cub suggested.

"Why, do you think his story is true and 'Bobby Crusoe' is a fake?"

asked Hal.

"I don't know. I wouldn't be surprised to find almost anything--or nothing--as we get near to the end of our hunt."

"But he must be on the island," Bud reasoned. "And he must have a wireless set, or he couldn't have sent the messages we got. That much is certain."

"Not all of it," Hal objected.

"Why?" Bud demanded.

"Maybe he isn't on an island."

"You mean, maybe the whole thing's a fake--eh?"

"Maybe."

"If the whole thing's a fake, then that other fellow who tried to head us off must 'ave been a party to the game," Cub interposed.

"There wouldn't be much sense in that," said Bud.

"I agree with you," Cub continued. "The sc.r.a.p between those two hams was genuine enough."

"But they were holding something back from us," Hal declared.

"Both of them?" asked Bud.

"I shouldn't be surprised."

"Nor I, either," said Cub.

"Then they've put one over on us," was Bud's inference. "Are you sorry we came?"

"I? No, sir!" Cub emphasized. "It's a dandy adventure, whatever the result. I didn't swallow that Crusoe story whole at any time."

"Neither did I," said Hal.

"I thought there were some funny things about it," Bud announced reflectively; "but I didn't know how to put them together or take 'em apart."

"That was my fix," said Cub; "and it's my fix yet."

"I guess we all agree that the whole affair is very strange," Hal concluded. "We really don't believe we've been told the truth, and yet we get in worse trouble when we try to make something else out of it."

"I wonder what your father thinks about it, Cub," said Bud.

"Oh, he accepts it at its face value for the sake of the adventure," the tall youth replied. "But he's wise enough to know there may be a lot of hocus-pocus in the business."

For nearly two hours the motor boat wound its way at a fairly good clip among the picturesque islands of the upper St. Lawrence, the radio compa.s.s fixing the course as certainly as the hunter's pursuit is directed by the nose of his hound. They had no way of telling, at any time, how far ahead was the object of their search, but they had the satisfaction of knowing that they were constantly approaching it. At last an unexpected climax threw their hitherto clear prospect into confusion.

This climax grew out of a series of confounding messages from the "lost islander".

"I see you coming," was the first of these messages.

"Where is he?" asked Cub and Bud in chorus. Hal was at the table and the other two boys were listening-in.

"I don't know," replied the operator. "One of you boys go on deck and see what you can see."

Cub dashed up the companionway two steps at a time. In a few moments he returned with the announcement:

"There's an open stretch of four hundred yards ahead of us. He's probably on the island at the other end. I'm going back on deck and watch for developments."

There was a speaking tube communicating between the pilot house and the cabin and through this Cub kept his boy friends acquainted with the progress of the search. They reached the island in question, but not a sign of human life was discoverable on it. The motor boat pa.s.sed around it, and meanwhile the radio-compa.s.s found the strength of its receiving directly down stream. Cub communicated this condition to the cabin, and Hal dot-and-dashed the following to "VAX":

"Where are you? We can't see you."

"I saw you," was the reply. "I climbed a tree and saw you headed right for this group of islands."

"No, no," objected Hal. "It must be another yacht."

"Aren't you a white cruiser with awning mid and aft, and pilot house on bridge deck?" asked "VAX".

"Yes," answered Hal.

"There's somebody calling us," remarked Bud at this point.

"Yes, I get 'im," returned Hal. "Why, it's the mysterious guy who tried to head us off night before last and yesterday."
