"It sounds to me," said Amy, "as though neither one of you boys knew so awfully much about it."

"I know one thing," said Jessie, with determination. "All the parts are not here. These connections are not like any I ever saw before. It is a mystery to me——"

"Hold on!" exclaimed Darry Drew suddenly. "What did we do with all those little cardboard boxes and paper tubes the parts came in? Couldn't be we overlooked anything, Burd?"

"Don't try to hang it on me!" exclaimed his chum. "I never claimed to know a thing about radio. You were the Big Noise when we put the contraption together."

"Aw, you! Where did we put the things left over?"

"There he goes!" exclaimed the confirmed joker. "He's like the fellow who took the automobile apart to fix it and had a bushel of parts left over when he was done. He doesn't know——"

"Beat it out of here," roared Darry, "and find that box we put the stuff into. You know."

Dr. Stanley came up to the radio room while Burd was searching for the rubbish box. The clergyman spoke cheerfully, but he looked very grave.
