e loud and clear. Now when you've got to that point, don't
overdo it. If you get too much regeneration, the quality of the notes
becomes distorted and before you know it you have only a jumble. Let well
enough alone is a good rule in tuning, as in many other things. When your
coffee's sweet enough, another spoonful of sugar will only spoil it. Keep
to the middle of the road. It isn't the loudest noise you want but the
sweetest music.

"Be careful, too," he urged, "not to have too brilliant a filament. It's
wholly unnecessary to have it at a white heat, and you don't want to burn
it out any more quickly than you have to. You can save money in reducing
the filament brightness by increasing the regeneration, which will make up
for the loss of brilliancy.

"Now by keeping these things in mind," he concluded, "you'll be able to
operate your set to the best advantage and get the satisfaction you are
looking for."

"We certainly hope to, anyway," said Bob. "We've put a lot of work and
quite a little money into this outfit, and we'd be mightily disappointed
if we didn't get good results."

"There's not much doubt about that, I think," remarked Frank Brandon. "You
ought to see some of the sets I come across! They look to be regular
nightmares, but they get passable results, anyway. Radio is certainly
getting to be a country-wide craze. Only the other day I was at one of the
big broadcasting stations, and the manager told me that they were actually
having trouble to get performers, there is such a demand for them. They
seem to be especially hard up for novelty acts--something out of the
ordinary. People get tired of the same old programmes night after night."

"Say!" exclaimed Bob, struck by a sudden thought. "Why wouldn't that be
just the thing for Larry when he gets a little better? He could do his
bird imitations just as well as ever, and he could do it as well sitting
in a chair, as far as that goes."

"Bob, you said something!" exclaimed Joe, slapping him on the back.
"That's just the kind of thing that would appeal to people, too. I'll bet
he'd be a hit from the beginning."

"Who is Larry?" asked Mr. Brandon, curiously.

The excited boys told him all about their acquaintance with Larry and Tim
up to the time of the almost fatal accident in the theater. Brandon
listened attentively, and when they had finished sat thinking for several
minutes.

"Yes, I think it could be arranged all right," he said at last. "I know
