“We’ve got a faint idea what they are, anyway,” chuckled Bob. “We’ve made enough of them to be on speaking terms, I should say.”
“Made them!” exclaimed the other, surprised in his turn.
“Sure thing,” grinned Bob. “We’ve made crystal detector sets and vacuum tube sets, and——”
“And other sets that we never knew just how to describe,” interrupted the irrepressible Herb, with a laugh.
“Yes, that kind too,” admitted Bob, with a grin. “But, anyway, we’ve made enough to know the difference between a variometer and a condenser.”
“Well, I didn’t know I was talking to old hands at the game,” said the operator. “I suppose I might have known that you wouldn’t take that long walk out here through the snow unless you were pretty well interested in radio.”
“Yes, we’re dyed-in-the-wool fans,” admitted Bob, and told the operator something of their radio work.
“I’m mighty glad to know that you fellows do understand the subject,” said the operator, when Bob had finished. “I’m so enthusiastic about it myself, that it is a real pleasure to have somebody to talk to that knows what I’m talking about. So many of the people who come here seem to be natural born dumb-bells—at least, on the subject of radio.”
“Such as you took us for at first, eh?” asked Jimmy, with a grin.
“I apologize for that,” said the other, frankly. “Please don’t hold it against me.”
