“So then I asked Jack if that was true, if he hadn’t heard any rumors of recent activity on the part of Ramirez, and he said he hadn’t. We talked a little more, and then I came on here. Thought this much would be interesting, anyhow, and that your friend Don Ferdinand might complete the picture. Now here you get a telegram which as good as says he’s on Ramirez’s track once more. Nothing to do but wait I guess.”

And the flyer subsided.

He had contributed real news, however. And their plans for a stroll forgotten, the four talked on until the subject had been exhausted.

Then the conversation turned to Jack’s radio experiments, and Captain Cornell, who was really interested despite his humorous lamentation that he couldn’t understand anything at all about the subject, asked numerous questions which Jack was kept busy answering.

Presently, acting on a sudden thought, Frank got up and unlocked a trunk. Delving into it, he reappeared with a small square box. This he placed on a table with an air of triumph, and throwing open the lid stepped back, gesturing like a showman, and said: “Behold.”

“Looks like some kind of a radio set,” said Jack, examining the contents. “And here, strapped in the lid, is a head-piece. Looks like radio, tastes like radio, must be radio. What is it, Frank?”

“It’s just what you said. Only it’s a trick set. Had a little time last Winter, and got to playing with an idea. Here, I’ll show.”

And carefully removing the whole business from the box, Frank proudly held it up for inspection.

“Why,” said Captain Cornell, “it looks like some kind of a belt.”

“And that’s just what it is,” declared Frank.
