“You are?” gasped the short man.

“Gee!” exclaimed his tall companion.

“I happen to be,” replied Tom. “And if you will leave us at my plant and come in so that I can thank you properly for what you did——”

“Aw, forget it!” snapped out the short man. “We don’t want any thanks. You’d do the same, wouldn’t you?”

“Of course,” said Tom. “But——”

“Forget it!” said the other again.

“At least tell me who you are,” begged Tom, as the two led the way to where they had left their small touring car.

“I’m Joe Hartman,” said the tall man who had admitted he was an aviator in the World War.

“And when I hear anybody yell for Bill Brinkley then I come and get my chow!” added the short chap whimsically.

“This is my friend, Miss Mary Nestor,” introduced Tom, and the girl held out a hand each to the two mechanics.
