A hundred yards back of the fleeing Buchanan, he cut the gun. The ship swept on with decreasing speed. A few yards behind the man on the ground, its speed was seventy-five miles an hour. Trowbridge, fighting the wind-blast, was standing up, both guns in his hands.

Then Sleepy took his chance. He nosed up, banking to the right at the same time. For a second the airplane hovered, right wing down, above its prey. Each of Trowbridge’s guns spoke twice. Like a flash, Sleepy rammed the throttle full on, glimpsing the fall of the horse below out of the corner of his eyes.

The fouled plugs did not catch immediately, and the infinitesimal delay was fatal. The ship, being so low and having lost flying speed, could not stay in the air any longer, and there was not altitude enough to pull out. In that split-second Sleepy had an opportunity, however, to do what he had planned all along if he did not win his gamble—for he had never planned that the grizzled old-timer in the back seat should take his full share of the flying chances.

Banked as it was, full top rudder would have dashed the ship into the ground on its side, and the Sheriff would have borne the brunt of the crash. Instead, Sleepy shoved the stick forward as far as it would go. With his arm thrown in front of his face, he rammed the ship into the ground. Wings sheered off on trees, and then came a stupendous crash that marked the cessation of consciousness for the pilot.

Trowbridge, stunned as his head was dashed against the front cowling of the cock-pit, found himself lying on his side in the middle of a twisted mass that represented the broken fuselage. He struggled weakly, and then sank back with a groan. Apparently his collar-bone was broken, and his right arm for some reason would not function.

He fumbled at the belt dazedly, and succeeded in freeing himself. Bit by bit, he crawled out of the débris, looking around for Spears. As he dragged himself out, the spat of a revolver sounded, and the whine of a bullet past his head made him duck so suddenly that he nearly fainted with the pain.

He peered toward the place where the shot had apparently come from, shielded from sight by the wreckage. Fifty yards away was the carcass of the dead horse, and even as he looked a man’s head lifted itself above the body. Trowbridge snaked his way the few inches to the remains of the cock-pit, and was rewarded with a shot that drilled through the débris just beside him. He found one of his guns, jammed between two twisted longerons. As his groping hand grasped it, a searing pain in his left leg seemed to come simultaneously with the crack of another shot.

It was a moment before his will proved superior to the physical weakness that all but overpowered him. Then he started to crawl, with infinite pains, the foot necessary to reach a point of vantage. Through the twisted wreckage he peered with bloodshot eyes, his sixshooter in his left hand.

Trowbridge’s right arm was wounded. With infinite pains, he crawled out, his revolver in his left hand.
