kinds of stuff on radio, and even loaned us a
practice set to get the code with."

"Don't forget about the motor boat," said Herb. "He was as generous with
that as with everything else. We sure had some fine cruises in the old Sea
Bird."

"That sounds like him, all right," admitted Brandon. "There's hardly
anything you could ask him for that he wouldn't cheerfully give you. He
told me that you fellows were getting to be regular sharps at the radio
game. Are you building any sets at present?"

"You bet we are!" cried Bob. "Come on down to my workroom, and we'll show
you what we're doing. We're working on a regular set this time."

"I'm with you," said Brandon, heartily. "Come ahead and let's see what
you've got. I suppose you'll be giving me pointers pretty soon."

"Not for a little time yet, anyway," grinned Bob. "The government hasn't
been after us yet begging us to take jobs in the radio department."

"You never can tell," replied Brandon. "There's a big demand for radio men
these days, and we're getting some pretty young chaps in our division."

"We don't feel as though we'd much more than scratched the surface of
radiophony yet," said Joe. "There's such an immense amount to be learned,
and then there are new discoveries being made every day. It would take
almost all a fellow's time just to keep up with new developments, let
alone learn all the fundamentals."

"That will all come in time," said the radio inspector. "You're on the
right road now, anyway, and traveling pretty fast. Say!" he exclaimed, a
moment later, as he was ushered into the workroom and caught sight of the
new set, which was partially completed. "You're certainly going into it
pretty heavily this time, aren't you? I didn't imagine you were working up
anything so elaborate."

"We thought we might as well make something pretty good while we were
about it," said Bob. "It won't be much more work to make this set than a
smaller one, and we expect to get a whole lot better results. Don't you
think so yourself?"

"There's no doubt about it," agreed Mr. Brandon. "When you get this set
finished, you ought to be able to catch pretty near anything that happens
to be flying around. Let's see how you intend to hook things up."

The boys explained their ideas and methods in detail, while the radio man
nodded appreciatively from time to time. Sometimes he interrupted to ask a
question or make a suggestion, which was duly taken note of by the
enthusiast
