"You're going to see one now," was all the retort Tom permitted himself.

"Here we go then!" cried the man, and he gave his gear handle a yank, and shoved over the sparking and gasolene levers.

His car instantly shot ahead, and went "chug chugging" down the road in a cloud of dust. At the same moment Tom, in answer to a look from Ned, who feared his friend was going to be left behind, turned more power into the motor. The humming, purring sound increased and the electric car forged ahead.

"Can you catch him?" asked Ned.

"Watch," was all Tom said.

The hum of the motor became a sort of whine, and the electric rapidly acquired speed. It crept up on the gasolene car, as an express train overtakes a freight, and the man, looking back, and expecting to see his rival far behind was surprised to note the queer looking vehicle lapping his rear wheels.

"Well, you are coming on, aren't you?" he asked. "Maybe you'll keep up now!" He shifted the gears, using a little more gasolene. For a moment his car opened a wide gap between it and Tom's, but the young inventor had only begun to race. Still louder purred the motor, and in a few minutes Tom was running on even terms with his competitor. The man looked annoyed, and tried, by the skilful use of gasolene and sparking levers, to leave Tom behind. But the electric held her own.

"I've got to go the limit I see," remarked the man at last, glancing sideways at the other car. "I'll tell 'em you're coming," he added, "though I must say your electric does better than any of its kind I ever came across."

"I'm not done yet," was the comment of our hero. But the man did not hear him, for he was yanking into place the lever that enabled him to run on direct drive for fourth speed.

Forward shot his car, and, for perhaps a quarter of a mile it led. The racers were almost at the end of the three-mile level stretch of road, and if Tom was going to win the impromptu contest it seemed high time he began.
