"When you two fellows are all through arguing, maybe we can go up and hook on our leading-in wire to the aerial," said Joe, impatiently. "We ought to get that much done before dark, anyway."

"I don't know about that, Joe," objected Bob. "It's almost dark now, and we could do it better and easier in the daylight. What do you say if you all come around after supper and we'll dope out a wiring diagram and maybe make a start on building the tuning coil."

Joe reluctantly consented to this, and the four companions separated for the time being, after promising to return to Bob's house that evening. And true to their promise, the boys had all returned to the Layton home by eight o'clock that evening, full of enthusiasm for the task that lay before them. Mr. Layton was mildly interested in the radiophone project, but after a few questions he retired to the library with the evening paper, leaving the boys to their own devices.

CHAPTER IX

WORK AND FUN

"Well, fellows," said Bob, "here we are, all set for a busy evening.
What shall we do first?"

"What I'd suggest," said Jimmy, "would be for everybody to have a little milk chocolate, just to start things off right," and he produced a huge bar of that toothsome confection and passed it around, with an earnest invitation to everybody to "help himself."

"It isn't such a bad idea, at that," admitted Bob, breaking off a chunk that made Jimmy gasp. The others imitated his example, and by the time the bar of chocolate got back to Jimmy it had shrunken so greatly that the last named individual gazed at it mournfully.

"Gee whillikins!" he exclaimed, "you fellows certainly do like chocolate, though, don't you?"

"I do, anyway," said Herb, laughing at the rueful expression on his friend's face. "Have you got any more when that's gone, Doughnuts?"
