anger, and
she settled back in her place.

Cora looked back at the oncoming boat of the young man. It was within
ten feet of her now, and as she opened the throttle of the _Chelton_ a
trifle more, she tried to get a glimpse of the controlling mechanism
of her rival's craft.

She stood up to do this, and, as she did so there came a slapping wave
against the bow of her boat. Cora staggered at the wheel, and Lottie
screamed.

"Be quiet!" commanded Cora. "It's all right."

"But we roll so!"

"There _is_ a bit of a sea on," admitted Cora, calmly. "It will be
over in a few minutes, though. I'll have to tell him we're close to
the danger point, and will have to slow down."

Determining to end the race in good style, Cora opened up the throttle
full, and advanced the spark to the limit. The _Chelton_ responded
with a sudden burst of speed that carried her some distance ahead of
the rival craft.

But the young man was evidently not going to take his defeat easily.
The louder exhaust from his engine told that he, too, had put on more
power.

But it was not enough, for as Cora raised her hand, in automobile-signal
fashion, to warn her follower of an impending stop, the end of the
impromptu race course was reached.

The girls had won.

"What is it?" called the young man as he stood up at his wheel.

"The rocks," answered Cora. "We can't race any more."

"We don't need to," he replied. "You won. I congratulate you!"

His tone was sincere, his manner courteous, but, as Cora looked into
his boat, when it rushed up alongside her slowed-down craft, she noted
that his throttle was still partly closed.

Instantly a suspicion came to her.

"He did not try to win!" was the suggestion that flashed to her mind.
"He didn't try!"

For a moment her brain was in a whirl, and she had an idea that she
ought to tell her chums what she had in mind. Then she decided to be
cautious--to wait and watch a little longer. She wanted to find out
his reason.

Who was this strange young man who seemed so friendly? What did he
want in Bayhead? Why had he proposed a race? And then, after proposing
it, why had he not won it when, clearly, he might have done so?

These were the questions that Cora asked herself as she slowed down
her motor.

She had used up her limit of power in an honest endeavor to win, but
the young man had not. He had held back purposely.

Why had he done it?
