ion in the United States, and perhaps even the large foreign stations.
Of course, this meant that their apparatus would have to be much more
intricate and expensive than any they had constructed hitherto, but the
realization of this did not deter them. On the contrary, the thought that
the task would be one to tax their skill and knowledge to the utmost only
served to make them more eager to begin. They examined numberless
catalogues and circulars in an effort to determine where and at what cost
they could obtain their necessary supplies, jotting down notes as they
went along. By supper time they had acquired a pretty good idea of what
their new equipment would cost, and were pleased to find that it came
within the amount that they thought they could get by selling two of their
present complete sets.

"Well, then," said Bob, in conclusion, as they heard the supper bell ring,
"the first thing we do when we get back home will be to sell the two sets,
and then we'll get busy on making the new ones."

With this the others agreed.

CHAPTER V

BACK FROM THE BEACH

"Good-bye, old bungalows, we hate to leave you. Here's hoping we see you
again next summer."

It was Herb speaking, as the radio boys and their families left the group
of cottages where all had spent such an eventful and pleasant summer.
Brilliant sunlight beat down on the yellow sand, but its heat was very

the air and sky, and the wind that came sweeping over the level sands had
a nip in it that made even Jimmy walk fast to keep warm.

They were to return home by train instead of automobile, and all the
ladies had gone to the station in the big motor omnibus, but the boys had
preferred to walk, as the distance was not great and there was still
plenty of time before the train was due.

"We've had a wonderful time here, there's no doubt of that," said Bob,
commenting on Herb's apostrophe to the bungalows. "But it will seem nice
to get home again, too. I've almost forgotten what the old town looks
like."

"It will seem good to see the old bunch at High once more, too," added
Joe. "I'll bet there aren't many of them have had the fun that we've had
ever since we landed at Ocean Point."

"Not only that, but we've learned a lot, too," said Bob. "We were running
in luck when we met Mr. Harvey and had the run o
