“Lie still!” commanded his companion sternly.  “I have a plan that we may be able to put into operation.  We can’t do it now, though.”

The lads waited, Tad almost with the patience of an Indian, Chunky ill at ease and restless.

“Can’t you lie still?  What ails you?”

“My stomach’s fighting my appetite.  Hear ’em growl at each other?”

“S-h-h-h.”

“I don’t care.  I’d ’bout as soon be scalped as to starve to death.”

The braves had by now filled their stomachs, gulping their food down without the formality of chewing it at all.  Stacy’s amazement was partly mixed with admiration as he observed the food disappear with such rapidity.

Now the braves had begun puffing at their pipes.  After a time, one by one laid down his smoking bowl and stretched himself out for a nap, just as Tad had said they would.  The savages were spread out so that they had a very good view of three sides of the rock on which the two lads were perched, but the fourth side was hidden from them.  Tad decided that, as the Indians showed no intention of moving, they were going to remain where they were until night.

“I want you to follow me, Chunky,” Butler said, determined to try his plan.  “You will have to move absolutely without a sound.  Look before you put down foot or hand.  Be sure where you place them.  We’ll wait a few minutes until they’re sound asleep.”

“What you going to do—­ sneak?”

“Try to get back to camp.  The others will be coming along looking for us pretty soon, if we don’t get away.  The Indians might resent being disturbed, and perhaps make trouble.”

“Tell me when you’re ready, then.”

Some minutes had elapsed and the lads could plainly hear the snores of their besiegers.

“Now!” whispered Tad.

At the same time he began crawling toward the edge of the rock at their rear.  Stacy was close upon his heels.

The side which the boys were to descend was much more precipitous than the one they had come up by, but offered no very great difficulties for two nimble boys.  Proceeding with infinite caution, they gained the ground without a mishap.

“We’ll walk straight on in this direction, until we get out of sight; then we can turn to the left and hurry to the camp.”

Stacy nodded.  As he did so his eyes were off the ground for a few seconds.  Those few seconds proved his undoing.

The lad stepped on a stone that gave way under him, turning his ankle almost upon its side.

“Ouch!” yelled Chunky.

“Now you’ve done it,” snapped Tad.  “We’ll have the whole pack of them down on us.  Can you walk?”

“I—­ I don’t know.  I’ll try.”

“Take hold of my hand.  You’ve got to run.”

The redskins were on their feet in an instant.  A few bounds carried them around the rock whence the exclamation had come.  By this time Tad had dragged his companion into the bushes but not quickly enough to elude the keen eyes of the savages.
