Casey left his digging and returned to the Ford, still determined to carry on the bluff and pretend that much tinkering was necessary before he could travel further.

With a great show of industry he rummaged for pliers and wrenches, removed the hood from the motor and squinted down at the little engine.
By that time Mack Nolan was snoring softly in deep slumber.

Casey listened suspiciously, knowing too well how misleading a snore could be.

But his own eyelids were growing exceeding heavy, and the soporific sound acted hypnotically upon his sleep-hungry brain.

He caught himself yawning, and suddenly threw down the wrench.
"Aw, hell!" he muttered disgustedly, and went and crawled under the back of the car where it was shady.
The sun was nearly down when Casey awoke and crawled out.
