“Why, you simps,” laughed Bert, “that’s no ghost, or if it is, it is the most solid spook I ever heard of. Those are the acetylene lamps of another auto,” and as he spoke he exchanged significant glances with Mr. Hollis.

Somewhat ashamed of having been so startled, the boys now fell to guessing at the mission of the strange car. They had not long to wait. In a few minutes they could hear the purring of its exhaust, and soon a great gray automobile dashed into camp and drew up in front of the fire.

From it descended a genial looking man, apparently of about the same age as Mr. Hollis, followed by five clean cut young fellows.

Mr. Hollis and Mr. Thompson, as the new comer’s name proved to be, evidently knew each other and shook hands heartily. Meanwhile the camp boys mingled with their unexpected guests and with the freemasonry of youth soon became chummy.

The only fault perhaps that could be found with the new arrivals was that they seemed to be a trifle overbearing, and evidently thought that their car, which they called the “Gray Ghost,” could beat any other automobile ever made.

It is needless to state that Bert’s crowd felt the same way regarding the “Red Scout,” so that the boys were soon engaged in a heated argument concerning the respective merits of their cars.

“Why,” maintained Tom, hotly, “you fellows have no idea what our ‘Red Scout’ can do in the way of speed and hill climbing. Just to-day we were out on a run and, though I didn’t actually time it, I am dead sure there were stretches where we did as well as a mile a minute. What do you think of that?” he asked triumphantly.

Indeed, this seemed to cool the visitors down somewhat and they exchanged surprised glances. But they soon recovered their confidence and went on to describe the speed qualities of their car with ever-increasing enthusiasm.

“It was just a short time ago,” said one whose name turned out to be Ralph Quinby, “that we took the ‘Gray Ghost’ around the old race track just outside the town, and we averaged over fifty miles an hour. We could have gone much faster too, only Mr. Thompson would not let us. I’ll just bet your auto couldn’t go as fast as that.”
