Matt got down and turned the engine over—and came within one of being run down before he could get out of the way. Regaining the car at a flying leap, he snuggled down in his seat and proceeded to hold his breath. Of all the reckless drivers he had ever seen, Tsan Ti was the limit. He banged over the edge of the level into the long slope, engaging the high speed so quickly that Matt wondered he did not strip the gear. As the car lurched, and swayed, and bounded Tsan Ti's joy shone in his puffy face.

"Glory to glory, and all hands 'round!" yelled the cowboy, from behind. "Change seats with him, Matt! If you don't, he'll string us from the Mountain House clean to Catskill."

Matt leaned over and gave the steering wheel a turn barely in time to keep them from hitting a tree. The wake the machine left behind it looked like a zigzag streak. First they were on one side of the road, and then on the other, juggling back and forth by the narrowest of margins, and keeping right side up in defiance with every law of gravity with which Matt was familiar.

"Cut out the high speed!" shouted Matt. "It's suicide to use that gear on such a slope as this. We could coast down this hill without an ounce of power."

A mud guard was loose, and it rattled horribly. The Chinaman was feeding too much gasoline part of the time, and not enough the rest of the time. Now and again, the cylinders would misfire, pop wildly, then jump into a racing hum. That high-powered roadster made as much noise as a railroad train; and what with Matt yelling directions, and McGlory whooping like a Comanche at every close call they nipped out of, the uproar was tremendous.

Through it all the fat Chinaman glowed and, at intervals, gave vent to ecstatic howls. Whenever they escaped a tree that had threatened them, he exploded jubilantly.

"I can't stand this, pard!" roared McGlory. "I'm goin' to jump out, if you don't stop him!"

To argue with Tsan Ti, in all that turmoil of sound, was out of the question.

Hardly had the cowboy ceased speaking when, through the wild hubbub of noise, Matt thought he heard a sharp detonation. Of this he was not sure, but, almost immediately, a front tire blew up, and the machine swerved wildly.

Bang—crash!
