How to drop from the saddle of the running horse and into the car was a point that Matt turned over in his mind as he raced. He had not many seconds in which to mark out a line of action—and he did not need many.

Pushing the horse to top speed, Matt passed the car; then, with a quick jerk on the reins, he brought the horse to a slower pace, tumbled out of the saddle, caught his footing in the road and flung himself at the running-board as the car came abreast of him.

He was jolted considerably, although no particular damage was done, and got into the tonneau with a wild scramble. By then the car was dangerously close to the bend, and Matt threw himself across the back of the front seat and into the driver's position. With lightning quickness he cut off the power and threw on the emergency brake. The machine halted, but with a telephone-pole almost between the front wheels!

With a deep breath of relief, Matt stood up to see what Carl was doing. The fat Dutchman was trying to head off and stop the horse. The animal, as soon as Matt had dropped from the saddle, had whirled back along the road. Not a little frightened, the horse seemed now about to turn in Matt's direction in order to escape Carl.

Hastily cutting away the wheel-lashing with his knife, Matt sprang from the car and ran back, so he and Carl could keep the horse between them. This move was successful, and the Dutch boy, by an exercise of marvelous agility for one of his build, managed to grab the horse by the bits.

"Vat shall I do mit him, Matt?" cried Carl.

"Take him back to the place where I got him, Carl," called Matt, "then bring that laundry of ours and come to the car. There's a mystery here that we've got to look into."

Matt's wild ride on horseback, and his capture of the car, had not brought a single person out of the squat little adobe houses sprinkled along the road. For the most part, the houses were inhabited by Chinamen, and they had little curiosity for the Melican man's devil-wagon; not enough, at least, to let the stopping of the car draw them from their own affairs.

Matt looked the machine over with an admiring eye. It was a fine late model, with six cylinders under the long hood. From the amount of dust with which the machine was covered it seemed to have come a long distance. The tires, however, were in excellent condition, the gasoline-tank was half full, and there was still a good supply of oil.

Familiar as Matt was with motor vehicles, he knew the car must have cost five or six thousand dollars. Why was such a valuable machine loose in the road? Who was the owner? And where was the owner?
