“We’re going to frighten dad into getting us a radio set by threatening to make one ourselves!”

“I shouldn’t wonder if they could make a set, at that,” said Bob thoughtfully, as they tramped on alone. “They’re smart enough.”

“For girls,” added Herb, condescendingly.

“Say, where do you get that stuff?” he jeered. “If those girls couldn’t make a better radio set than you, I’d sure feel sorry for them.”
