"Mercy me!" cried Walter, who had left the car and joined Jack.
"Now, Cora," he added mockingly, "when you start out to save lives,
why don't you give a fellow the tip? There's nothing I do so love as
to see lives saved--especially nice young ladies," and he made a low
bow.

"Oh, you may laugh," said Cora somewhat indignantly, "but I don't
want anything like it to happen again. The brake would not work,
and--"

"The train was just in front of us, and we were running right in
it," put in Isabel, her voice far from steady, and her face still
very white.

At this point Ed insisted upon telling the whole story, and he
described the plight of the motor girls so graphically that both
Jack and Walter were compelled to admit that Cora did indeed know
how to drive a car in an emergency, and that she had acted most
wisely.

"Good for you, sis!" exclaimed Jack, when the story Was finished.
"I could not have done better myself."

"Such praise is praise indeed," spoke Ed with a laugh.

He went around back to look at the brake, and found what had caused
the trouble. A loose nut had fallen between the brake band and the
wheel hub, and prevented the band from tightening. The trouble was
soon remedied, and the brake put in working order.
