“It—the whole thing—seems impossible,” added Ruth, while Mrs. Salper found herself quite as interested as her daughters.
“Yes, that’s the way it seemed to us at first,” agreed Bob, his eyes shining. “When Doctor Dale told us we could make a set for ourselves we could hardly believe him. But it didn’t seem a bit hard once we got started and learned the hang of it.”
“You mean to say that you made this set yourselves?” asked Mrs. Salper, with interest.
“Oh, this is nothing. We’ve made lots of ’em,” said Jimmy proudly, at which Herb promptly kicked him under the table. The injured Jimmy glared at his assailant, but the others were too much interested in the subject to notice him.
“You see this is a comparatively small set,” Bob explained.
“But we’re working on a powerful apparatus now,” broke in Joe eagerly. “And when we have that in working shape we’ll be able to send as well as receive.”
“Well, I think you’re just as smart as father said you were,” said Ruth, and at this candid compliment the confused boys thought it time to change the subject.
“How about listening in a while?” suggested Bob, struck by a sudden inspiration. “We ought to be just about in time to catch the afternoon concert—if there is one. Would you like to find out?”
“Would we?” cried Edna, enthusiastically. “Indeed we would!”
“Just try us,” added Ruth happily.
