"Can't do it. Not a bit sleepy," declared Hiram. "Well, you can try it while I'm gone," suggested Dave. "Oh, going somewhere?" "Yes, to the town. I want to make a few inquiries as to the country around here and ahead of us, and I may wire Mr. Randolph." "All right, go ahead," replied Hiram. "I'll see that everything is kept trim and safe about the machine." Dave visited Millville, and posted himself as to certain geographical points in which he was interested. He also sent a brief dispatch to the Interstate people. Provided with some railroad maps, and some fresh rolls from a bakery, he started out to rejoin his chum. He found Hiram busy burnishing up every bit of metal about the Monarch II. They had their noon lunch. On his way back from town Dave' had noticed a little brook. He was telling Hiram about it, and they were discussing a plan of a plunge and a swim, when Hiram, facing the point where the pit began, sprang suddenly to his feet. "Hello!" he cried excitedly. "Someone is coming." "Sure enough," echoed Dave, also arising. "Why, I noticed that man in Millville. Can it be possible that he has followed me? I didn't know it, if he has." The boys stood motionless, awaiting the coming up of the intruder. He was a brisk, smart looking man. There was something in his sharp way of glancing at things that made Dave think of a lawyer. The stranger came up within a dozen feet of them. Then he halted, took in the flying machine with a grim smile, and then looked the young aviators over from head to foot. "Reckon I've landed on both feet," he observed, a confident, satisfied drawl in his voice. "What do you mean by that?" inquired Dave. "Why, I've been looking out for an airship said to be cruising around this neighborhood. Truck farmer said he saw one early this morning. Then I noticed you in town. I think you'll understand me, young man," continued the stranger, "when I say that I'm on the hunt for a chap about your size running a stolen airship, and whose name is Jerry Dawson." "Why," exclaimed Dave with a quick start, "so are we!" CHAPTER XVII ON THE WING Hiram stared his hardest at the stranger, Dave's eyes quickened with sudden intelligence. Almost in a flash he took in the situation. "You just mentioned a name," he said. "I would like to mention another one." "All right, what?" "James Price." "Hello!" The stranger looked flabbergasted, as the saying goes. He furrowed his brow as if puzzled. "You have made a mistake," continued Dave. "You think one of us two is Jerry Dawson." "I did think it, yes," admitted the man, a trifle less self assured than at first. "Wrong." "Is that so, now?" "Yes. You know Mr. Price, don't you?" "Perhaps I do." "And you are on the lookout for an airship, but not this machine. Let me explain briefly, and see if we cannot come to an understanding."
