He straightened up and placed a dot on the map before him.

"That's where he was. I'll motor out in the morning and have a look at things. May discover some clew."

Curlie was a bright American boy of the very best type. Like most American boys who do not have riches thrust upon them, when he wanted a thing he made it or made a way to get it. Three years previous he had wanted an automobile—wanted it awfully. And his total capital had been $49.63. He had been wanting that car for some time when an express train hit a powerful roadster on a crossing near his home.

Having flocked in with the throng to view the twisted remains of the car, he had been struck with an idea. This idea he had put into action. The railroad had settled with the owner for the car. They had the wreck of it on their hands. Curlie bought it for twenty-five dollars.

To his great delight he had found the powerful motor practically uninjured. The driving gear too, with the exception of one cog wheel, was in workable order. The remainder of the car he sold to a junk dealer for five dollars. It was twisted and broken beyond redemption.

He had next searched about for a discarded chassis on which to mount his gears and motor. This search rewarded, he had proceeded to assemble his car. And one fine day he sailed out upon the street with the "Humming Bird," as he had named her.

"Better call her 'Gravel Car,'" Joe had said when he saw that she had no body at all and that he must ride with his feet thrust straight out before him in a homemade seat bolted to a buckboard-like platform.

But when, on a level stretch of road, Curlie had "let her out," Joe had at once acquired an immense respect for the Humming Bird. "For," he said later, "she can hum and she can go like a streak of light, and that's about all any humming bird can do."

No further messages of importance having drifted in to him from the outer air, Curlie, an hour before dinner, made his way down to the street and, having warmed up the Humming Bird's motor, muttered as he sprang into the seat: "I'll just run out there and see what I see."

A half hour later, just as the first gray streak of dawn was appearing, he curved off onto a gravel road. Here he threw his car over to one side and, switching on a flashlight, steered with one hand while he bent over the side to examine the left-hand track.
