Major Orville Potts stood in the soft grass and rested a gloved hand on the upper wing of his flying machine.

"Sir," he said, "with my invention, the Confederacy will soon put the Yankees to rout."

The general stroked his gray goatee and pursed his lips. Potts felt pleased that every detail of the general's uniform stood out in bold clarity. The slouch hat, gray coat, red sash, and black jackboots were more real than life. Of course the surrounding landscape was a green blur, but increased concentration would clear that.

The general said, "Ah'm doubtful, Majah. Balloons, Ah undahstand. Hot aiah natuahlly rises, but this contraption seems too heavy to fly."

"No heavier, in proportion, than a kite, sir," Potts explained.

The crude mountaineer captain, standing slightly behind the general, snickered.

"Hit won't work nohow," he predicted. "Jist like that there Williams repeatin' cannon at Seven Pines. Ain't even got no steam engine fur as I kin see."

Potts said, "This is a new type engine. It operates on a formula of my own, which I have named gasoline. Now, if you gentlemen will excuse me, I shall proceed with the demonstration."

Potts climbed into the cockpit. A touch of the starter set the 1,000 h.p. radial engine roaring. He waved to the gaping officers and opened the throttle. The bi-plane whisked down the field and rocketed into the blue morning sky.

Too late, Potts saw the buzzard soaring dead ahead. He shoved the stick forward, but the black bird rushed toward his face in frightening magnification.
