Grinning, Jack joined in, and the three went rolling and threshing about the bushes like a trio of young bears.
At the fireside, Mr. Hampton’s worried look relaxed, and he grinned with enjoyment.

CHAPTER XI.—BOB FALLS ASLEEP.
In no time at all, Mr. Hampton and his party were ready to set out. Of one thing they were reminded by Jack, the individual radio sets constructed along his own lines, the instrument of which was so small and compact it was contained in the panel of a ring.
“Only trouble with these,” Jack said, “is that you can receive but can’t transmit. However—”
“However,” his father interrupted, “that is all that will be necessary.”
“Why?” asked Farnum.
“It is hardly likely that the five of us will get into such a predicament that we shall fail to return,” explained Mr. Hampton. “But the boys may be attacked when we are gone, and may be placed in a bad position. Then they can call for us.”
“At least we could send out a hurry up call over those sets,” said Jack. “As for your calling us, well, that will be a little more complicated, Dad, but it can be done, if necessary. I insist on your taking that army field set. It came in mighty handy in South America. It is no great job to set it up. And it weighs little. You are taking no other equipment, and you can afford to take it along. It won’t be in your way. Here it is, you see, all boxed up complete, handle on the box and everything.”
