The machine dips sharply over the top of a hangar, straightens out again near the earth at a dizzy speed a few feet above it and, losing momentum in a surprisingly short time, hits the ground with tail and wheels. It bumps along a score of yards and then, its motor whirring again, turns, rolls toward the hangar, and stops. A human form, enveloped in a species of garment for all the world like a diver's suit, and further adorned with goggles and a leather hood, rises unsteadily in the cockpit, clambers awkwardly overboard and slides down to terra firma. A group of soldiers, enjoying a brief holiday from the trenches in a cantonment near the field, straggle forward and gather timidly about the airplane, listening open-mouthed for what its rider is about to say. "Hell!" mumbles that gentleman, as he starts divesting himself of his flying garb. "What's wrong now?" inquires one of the tenants of the tent. "Everything, or else I've gone nutty," is the indignant reply, delivered while disengaging a leg from its Teddy Bear trousering. "Why, I emptied my whole roller on a Boche this morning, point blank at not fifteen metres off. His machine gun quit firing and his propeller wasn't turning and yet the darn fool just hung up there as if he were tied to a cloud. Say, I was so sure I had him it made me sore--felt like running into him and yelling, 'Now, you fall, you bum!'" The eyes of the _poilus_ register surprise. Not a word of this dialogue, delivered in purest American, is intelligible to them. Why is an aviator in a French uniform speaking a foreign tongue, they mutually ask themselves. Finally one of them, a little chap in a uniform long since bleached of its horizon-blue colour by the mud of the firing line, whisperingly interrogates a mechanician as to the identity of these strange air folk. "But they are the Americans, my old one," the latter explains with noticeable condescension. Marvelling afresh, the infantrymen demand further details. They learn that they are witnessing the return of the American Escadrille--composed of Americans who have volunteered to fly for France for the duration of the war--to their station near Bar-le-Duc, twenty-five miles south of Verdun, from a flight over the battle front of the Meuse. They have barely had time to digest this knowledge when other dots appear in the sky, and one by one turn into airplanes as they wheel downward. Finally all six of the machines that have been aloft are back on the ground and the American Escadrille has one more sortie over the German lines to its credit. PERSONNEL OF THE ESCADRILLE
