"Twenty minutes to loaf," advised Rutter, throwing himself on
the ground and closing his eyes. "I'll take a nap. You'd better
follow my example."

"Then who'll call us?" asked Tom.

"I will," gaped Rutter.

"Without a clock to ring an alarm?"

"Humph! Any real backwoods engineer can wake up in twenty minutes
if he sets his mind on it," retorted Jack.

This was a fact, though it was the first that Tom or Harry had
heard of it.

"See the time?" called Rutter, holding out his watch. "Twenty
minutes of one. I'll call you at one o'clock---see if I don't."

In that fine air, with all the warmth of the noon hour, there
was no difficulty in going to sleep. Truth to tell, Tom and Harry
had tramped so far that forenoon that they were decidedly tired.
Within sixty seconds both "cubs" were sound asleep.

"One o'clock!" called Rutter, sitting up and consulting his watch.
"Fall to, slaves! There is a big batch of work awaiting us.
Hazelton, you can go right on where you left off. Survey along
carefully until you come upon a stake marked 'Reade.' Then come
forward until you find us. Reade, I'll go along with you and
show you where to break in."
