"We'd better save our scrapping for Buck Looker and his friends," said
Bob. "I suppose they'll be up to some kind of mischief as soon as we get
back to school again. They seem never to learn by experience."

"They're too foolish and conceited to learn much," observed Joe. "They
probably think they know all there is to know already."

"In spite of that, we may be able to teach them a trick or two," said
Herb. "But whether you fellows know it or not, it's getting pretty late,
so I think I'll go and hit the hay. Who's coming my way?"

"I suppose we might as well all beat it," returned Joe, rising. "If we
don't see each other to-morrow, I suppose we'll all meet at the dear old
high school on Monday morning. Three silent cheers, fellows."

"Consider them given," laughed Bob. "But we'll have plenty of fun, too, so
why mind a little hard work?"

After hunting in odd corners for their caps, the boys finally found them
all and departed gayly on their way, only slightly depressed by the
imminence of the fall term at high school.

CHAPTER VII

LEARNING TO SEND

"I've got two customers for those sets we wanted to sell," announced Bob,
a few evenings later, when the radio boys had congregated at his house as
usual. "It was so easy, that I'll bet we could sell all we make, if we
wanted to."

"Who's going to buy them?" asked Joe.

"Dave Halley, who runs the barber shop near the station, wants one, and
there's a big novelty store on the next block whose owner will take the
other. I promised that we'd set the outfits up and show them how to work
them."

"That's quick work, Bob," laughed Herb. "How did you come to land two
customers so quickly?"

"I was getting a haircut in Dave's shop, and he told me that he was
thinking of buying a good set, but hated to spend the money. So I told him
that I could sell him a good practical set for quite a little less than it
would cost him in a store, and he jumped at the offer. Then he told me
about Hartmann, the owner of the new variety store. Hartmann wants to get
one because he thinks it will draw trade. I went to see him as soon as
Dave got through telling me how much dandruff I had and how much I needed
some of his patent tonic. Mr. Hartmann was a little doubtful at first
about buying a home made set, but I told him if he wasn't pleased with it
he didn't need to pay us for it and we'd take it back. That seemed to
satisfy him, so he said he'd buy it. It was de
