"Why can't we do something? If you lie down now it will be gaining just
so much more sleep, and surely both of us can keep watch as well as
either you or he."

"That is a good idea, and I'll take advantage of the offer. Call me if
you see the slightest thing suspicious, or hear any sound not made by
the birds. I don't fancy we shall be troubled; but at the same time no
one knows what may happen."

"We'll take good care; you shall be told if anything larger than a rat
comes in view," Teddy replied, "so don't lose time that might be spent
in sleep."

Cummings followed this advice at once, and in a few moments his heavy
breathing told that he had crossed over into slumberland.

During the next hour nothing was seen or heard by the sentinels, who sat
just within the shadow cast by the rock gazing intently down the hill,
and then Teddy whispered excitedly as he pointed to a clump of bushes
near where the trees were thickest:

"Look in that direction. Can't you see the foliage is moving to and fro

said:

"I see what you mean: but there is probably some animal among the
bushes. At all events we shan't be a great while finding out, and it
isn't well to call Cummings until we are positive something is wrong."

During five minutes the boys watched intently, and then there could be
no question but that the leader should be awakened. They had seen a man,
or at least a portion of one, as the foliage was parted gently to admit
of his looking out, and Neal said as he raised his gun:

"Call Cummings. I won't fire until he gives the word unless that fellow
comes too near."

Believing that they were about to be attacked, Teddy shook the leader of
the party vigorously as he whispered:

"They've found out where we are, and one is just getting ready to make a
rush."

This information was well calculated to arouse Poyor as well as the
white man, and they ran with all speed toward the entrance to the ravine
where Neal was making ready to shoot.

"He has shown himself twice since Teddy went to call you," the boy said,
"and I know exactly where to fire if you believe it ought to be done."

"Do you think he knows we are here?" Cummings asked, and Neal replied:

"He has been looking out from among the bushes as if suspicious that
there was something wrong in this quarter; but I don't fancy he has seen
