Walking through San Mateo, Carl swung his cocky green hat and scanned the sky for aircraft. He saw none. But as he tramped out on the flying-field he began to run at the sight of two wide, cambered wings, rounded at the ends like the end of one's thumb, attached to a fragile long body of open framework. Men were gathered about it. A man with a short, crisp beard and a tight woolen toboggan-cap was seated in the body, the wings stretching on either side of him. He scratched his beard and gesticulated. A mechanic revolved the propeller, and the unmuffled motor burst out with a trrrrrrrr whose music rocked Carl's heart. Black smoke hurled back along the machine. The draught tore at the hair of two men crouched on the ground holding the tail. They let go. The monoplane ran forward along the ground, and suddenly was off it, a foot up, ten feet up--really flying. Carl could see the aviator calmly staring ahead, working his arms, as the machine turned and slipped away over distant trees. His first impression of an aeroplane in the air had nothing to do with birds or dragon-flies or the miracle of it, because he was completely absorbed in an impression of Carl Ericson, which he expressed after this wise: "I--am--going--to--be--an--aviator!" And later, "Yes, _that's_ what I've always wanted." He joined the group in front of the hangar-tent. Workmen were hammering on wooden sheds back of it. He recognized the owner, Dr. Bagby, from his pictures: a lean man of sixty with a sallow complexion, a gray mustache like a rat-tail, a broad, black countrified slouch-hat on the back of his head, a gray sack-suit which would have been respectable but unfashionable at any period whatsoever. He looked like a country lawyer who had served two terms in the state legislature. His shoes were black, but not blackened, and had no toe-caps--the comfortable shoes of an oldish man. He was tapping his teeth with a thin corded forefinger and remarking in a monotonous voice to a Mexican youth plump and polite and well dressed, "Wel-l-l-l, Tony, I guess those plugs were better; I guess those plugs were better. Heh?" Bagby turned to the others, marveled at them as if trying to remember who they were, and said, slowly, "I guess those plugs were all right. Heh?" The monoplane was returning, for a time apparently not moving, like a black mark painted on the great blue sky; then soaring overhead, the sharply cut outlines clear as a pen-and-ink drawing; then landing, bouncing on the slightly uneven ground. As the French aviator climbed out, Dr. Bagby's sad face brightened and he suggested: "Those plugs went better, Munseer. Heh? I've been thinking. Maybe you been giving her too rich a mixture." While they were wiping the Gnôme engine Carl shyly approached Dr. Bagby. He felt frightfully an outsider; wondered if he could ever be intimate with the magician as was the plump Mexican youth they called "Tony." He said "Uh" once or twice, and blurted, "I want to be an aviator."
