After getting out of the airplane, Mr. Giddings was thoughtful for some minutes. Nor did he speak until the boys had pushed the machine into the hangar. Then he said, with deep earnestness: "Young men, a great load has been removed from my mind by this recent performance of the Sky-Bird II. I have now not the slightest doubts of her adaptability to make a round-the-world trip, and if she performs then as she did this morning, we are not only going to defeat the _Clarion_'s crew, but we are going to smash all existing records for a journey of the kind. I wish to know if you really think you could operate this machine steadily night and day, say for a couple of weeks, stopping only for fuel and food?" "By alternating the engines--yes, sir; no doubt of it," declared John Ross without a moment's hesitation, while Tom Meeks nodded his frowsy head energetically. "Then," said Mr. Giddings, "you may consider that's what the entire four of you will have to do in a few months, as soon as we can pick out a route and get fuel supplies at the different airports or stops for you. John, you and Tom may consider yourselves under salary right on until after this race; there will be enough for you to do, helping me with arrangements and taking care of the airplane." "Well, but how about Paul and me, dad?" broke in Bob anxiously; "aren't we going to have anything to do?" "Oh, you two will have enough to do going to school, I think," laughed Mr. Giddings; "but, to satisfy you, I will let you both help John and Tom select a route and make out a schedule. Do this just as soon as you can, so that I may be able to give Mr. Wrenn, the publisher of the _Clarion_, a copy. He can then make intelligent preparations for his own crew. I am going to give my rival every consideration in this matter, so that he cannot do any howling if we beat him. It must be an out-and-out fair race, do you understand?" All nodded. "Have you heard anything about the other crew yet, Mr. Giddings?" inquired Paul. "I mean, do you know what sort of a craft they are going to use, or who is going to fly against us?" "I am as much in the dark about those points as you young men," was the reply. "I judge that Mr. Wrenn, who is an astute business man, will keep us in ignorance of his personnel until the last minute. The fact is, I am going to treat him to a dose of his own medicine in this respect. So be careful not to let the public get close to this machine, and talk with no one about it." With that the publisher and Bob drove home, but the latter came back in the afternoon, and all four young men immediately repaired to the Yonkers Public Library with a blank tablet, there to work out the route and schedule.
