"Maybe we wouldn't like to give old Auntie a whack at the Boches," declared valiant Jerry. "I'll bet we could do up a few Prussians before we got ours." "It's this way with us," confided Jack. "We've had practice and made some fair flights. Next week we're off to enlist in the Aviation Corps, if they'll take us. We're just past nineteen, but Uncle Edward has given his consent. We know a little bit about the flying game besides handling the plane. Ever since the war began we've been studying up on engines, machine guns, military law and all that. We can make maps and read 'em too. We'll have to go to an Aero school, if we're accepted, but when we get there we're going to pretty soon show 'em from the start that we're regular flyers. A good many fellows that go into the aviation corps never see their chance to get off of the ground. But not the Twinkle Twins. We're crazy to go over quick." "Maybe bob up in front of good old Emile and spring a surprise on him," averred Jerry, who seemed fond of supplementing his brother's remarks with one or two of his own. "Hope we'll see you again before you go," Jimmy said warmly. "Why can't you come up to camp to-morrow? We'd be glad to show _you_ around. We're all going home on Wednesday for Thanksgiving. By the time we get back you may be gone." "Much obliged for the invitation. We'll take you up on it and drive over to-morrow afternoon in the racer. We went up there once when we first came east. Since then we've been pretty busy with Auntie. Never happened to fly so near Sterling until to-day. We've always started off in other directions. You'll have to wise us where to find you and all about it. We don't want to miss seeing you." "Tell us what time you'll be there and we'll meet you in front of the Y. M. C. A.," proposed Roger. "How about two P. M. to-morrow?" "O. K.," replied Jack. "That'll suit us," from Jerry. A cordial but hasty handshaking all around, and the Khaki Boys departed, casting frequent backward glances at the aeroplane. Its owners had already begun to busy themselves with "Auntie" preparatory to taking flight. "It must be great to fly," glowed Bob. "Those twins are wonders. I mean the way they've rigged up that plane and all that. I had to smile to myself, though, at what that one said about flying Auntie against the Boches. You can figure how long that little light-weight, with its patchy wings and misfiring engine, would last against a Fokker. Bing, bang! Away goes Auntie; all shot to pieces. They've got the proper spirit, just the same." "Wish we would meet 'em again in France," emphasized Jimmy. "I was struck dumb when they claimed Voissard as a relative," declared Bob. "If it hadn't been for that Red Cross Bazaar we'd never have met the Twinkle Twins. Talk about looking alike! They certainly are the original duplicates. But for goodness' sake, what's a dihedral angle?" "Don't ask me. You know more about planes now than either Blazes or I," shrugged Roger.
