“Yes, and then getting us out again,” he said.

“Well, let’s try the radio, anyway,” suggested Jack. “They’ve been gone three hours. With the best of luck they can’t have made more than eight or ten miles, considering the detour they planned to take, and everything.”

“Couldn’t have gotten that far away in a straight line,” said Frank.

“No, I guess not. But what if they aren’t prepared for a call from us?”

“Oh, with that improved ring set of yours, your father will be proceeding fully equipped to hear from you,” said Frank. “He need only wear the headphone, and I seem to remember he said on leaving that he would keep it on most of the time.”

Jack nodded. The improvement in the ring set, spoken of by Frank, had done away with the necessity for the umbrella aerial.

“All right,” he said. “I’ll call Dad on 200 meters. If he gets the message we ought to hear from him shortly, for he’ll at once unlimber the field transmitting set and call us back.”

While Jack sent out a terse description of the fight and its outcome, Frank and Bob decided to steady their nerves by fishing and went down to the lakeside. They had reasonable success and had pulled out a number of fish when Jack joined them.

“Send out your message, Jack?” Frank inquired.

“Yes, and heard from Father in reply, too.”
