"That's a queer machine," said one.

"Yes, but it looks speedy," was another's opinion.

"There's the car for my money," added a third, pointing to a big red electric which was certainly whizzing around the track. Tom noted the red car. Behind it was a green one, also moving at a fast rate of speed.

"Those will be my nearest rivals," thought the lad, as he guided his car onto the track. A moment later he was sending the auto ahead at moderate speed, while the other contestants looked at the new arrival, as if trying to discover whether in it they would have a dangerous competitor.

CHAPTER XXV

WINNING THE PRIZE

After making two circuits of the track at moderate speed, Tom turned on more power, deciding to see how the machine would behave on the turns, going at a fast speed. As it happened he forged ahead just as the big red car was coming up behind him. The driver of it took this for a challenge and threw his controller handle forward.

"Come on!" he cried to our hero, when even with him.

Tom did not want to decline the invitation, and the impromptu race was under way. Soon the green car came rushing up, and for two miles the three kept almost in line. It was evident that neither the green nor the red car drivers wanted to "open out," until they saw Tom do so.
