"It's a new kind," retorted Harold knowingly, thinking that Ruth, like most girls, probably knew nothing about tools.
Jack glanced over his shoulder at the object; then dropped what he was doing to examine it more closely.
"By George! Ruth's right! Where is the part that goes under the axle?"
Harold was out of the machine in a jiffy.
"Great snakes!" he howled, tearing his hair. "It does come off; and if I can't find it under the seat, we're out of luck, that's all!"
He dived again into the car, leaving the other two staring at the dismembered jack. They heard him fumbling around again, and, after a minute, he slid out and sat upon the running-board.
"No use! I guess I left it home," he said.
"Then I guess I won't need this," said Ruth, handing Jack his watch.
Suddenly, the humor of the situation struck all three of them at once, and they burst into shrieks of laughter.
"Well, catching them is now out of the question," said Jack, after the merriment had subsided; "but we'll have to get home again somehow."
