"And evenings. I'd be willing to work after supper every night for a couple of hours," proposed Paul.

"You won't do any such thing," came the firm answer. "While you are at school you two fellows need your evenings for rest and study, and your Saturdays for the school-team sports. Only when there isn't a game on in which you are a contestant will I allow you to help John on the machine—even if it isn't finished for five years. I have been thinking this situation over for some time, for I have seen it coming," went on the great publisher after a moment's pause; "and I have come to the conclusion that the best thing I can do to hustle our ship along is to call in another workman on the job, some chap we can trust and who knows how to handle tools. In fact, if he were a regular airplane mechanic it would be all the better."

John Ross spoke up at once. "Mr. Giddings," he said, "I think you have the right idea. Bob and Paul can't help me much from now on, and if we take that trip around the world next summer this machine must be done some weeks ahead, so that we can have a chance to test her out and tune her up. Now, it happens that Paul and I have a cousin—Tom Meeks—who is about my age and who flew in the same squadron with me over on the French front during the war. I will vouch for Tom's ability as a mechanic and flyer, also as to his trustworthiness. It happens my mother just received a letter from Tom's folks in Illinois the other day in which she said the factory had closed down in which he was working and he was out of a job."

"And you think this Tom Meeks would be willing to come up here, then, and help you this winter for the salary I am paying you?" questioned Mr. Giddings with interest.

"I think he would, sir."

"Then write to him immediately, and tell him to come right on."

In less than a week a strapping big young man, suitcase in hand, got off the train at the Yonkers depot, and was warmly greeted by his cousins, Paul and John Ross, who then introduced him to Bob Giddings. Bob had been so eager to see the new helper on the airplane that he could not wait for a later meeting with him. He took instant liking to the jolly newcomer, who seemed to be ever smiling, and after a short exchange of conversation with him hurried home to tell his father what a splendid fellow Tom Meeks was.

Tom was domiciled in the Ross home, to which he had been a visitor in other years, and of course for the rest of that evening was kept busy visiting with Mrs. Ross and looking at the numerous miniature airplanes of Paul's. His praise of the little Sky-Bird, and particularly of the drawings of Sky-Bird II was very strong, and when he went to the fair-grounds the following morning with John and actually saw what a fine-looking ship the big craft was, he was stumped for words to express his full admiration.

Then while John and Tom went industriously to work, Paul and Bob rode away to Clark Polytechnic in New York with Mr. Giddings. Just before starting into the city that morning, the newspaper man had met Tom, and there was little doubt that he was well pleased with this addition to his force of workers. Of course Paul and Bob were sorry to have to interrupt their labors on Sky-Bird II, but there was no help for it, and there was some consolation in the thought that undoubtedly their instructors would let them work on some of the airplane's smaller parts as a portion of their school mechanical practice. This supposition indeed proved correct, and as the fall days passed they found the two student chums not only partaking with full spirit in the sports of their comrades, but also contributing in no small measure to the progress of the work on the new airplane.

As a rule, Paul and Bob managed to stop in each Saturday for at least an hour or so to lend some assistance to John and Tom, and when there were no school contests on, they spent practically the entire holiday in the hangar.
