Dave had been anxiously walking up and down the floor while Hiram was talking. Now he took his cap off a peg and picked up an umbrella. "You wait here till I come back, Hiram," he said. "Where are you going, Dave?" "Down to the Aegis hangar. This telegram disturbs me very much. I have no idea where Mr. Timmins can be, and something must certainly be done about this contract." "That's so, Dave," agreed Hiram. "It isn't exactly our business, but it would be a big feather in your cap to help out the people who are hiring you." "That's what I want to do, if I can," replied Dave, as he left the place. The youth went straight to the Aegis hangar, where he found Grimshaw tinkering over a broken airplane wing. Mr. King had a desk in one corner of what he called his office room. Dave was free to use this at all times. He opened it now, and for ten minutes was busy with some railroad time tables he found there. Then he consulted an aero guide map. Grimshaw watched him from under his shaggy eyebrows, but said nothing until Dave got up from the desk, buttoned his coat and prepared to face the storm again. "What's the trouble, Dashaway?" he asked. "Why, Mr. Grimshaw?" inquired Dave, wishing to evade direct questioning. "You seem bothered about something, I see." "Well, as a matter of fact, I am," confessed Dave. "What is it?" "I'm trying to find a way to get to Kewaukee," explained Dave. "Something has come up that makes me think I ought to be there in the interests of my employers early to-morrow morning. I am figuring out how I can make it." "See here, Dashaway," spoke the old airman in a grim, impressive way, "don't you do anything reckless." "I won't," answered Dave. "You know you once said I was all business. Well, I'll always try to do my duty without any unnecessary risks." Dave laughed carelessly and got away from the hangar. A daring idea had come into his mind. Perhaps Grimshaw suspected it, and Dave was afraid he might. The lad knew that the eccentric old fellow liked him, and would try to dissuade him from any exploit of unusual peril. "I'll do it, I'll have to do it or let the company lose out," breathed Dave, as once outside he broke into a run across the aviation field. Dave found Hiram winding the alarm clock as he re-entered the half shed, half canvas house where the Baby Racer was stored. Although they got their meals at Mr. King's headquarters, the boys had two light cots and slept near to the machine which Dave had been exhibiting. Dave glanced at the clock, and Hiram noticing the look, said: "Eleven thirty, Dave. I've set the alarm clock for five thirty. You know that new hydroplane will probably come in on an early freight. What's the programme?" "Well, Hiram," responded Dave, throwing off his coat and hat, "I'm going to dress up for a ride." "Eh?" ejaculated Hiram, staring hard at the set resolute face of his comrade. "Yes, I've got to get to Kewaukee." "Oh, you mean going by train?"
