d not move.

"Kiopo!" he called. "Kiopo!"

The wolf never turned his head. Dusty Star looked nervously back along
the gorge. A few moments afterwards the figure of an Indian came quickly
around the turn. Rigid as the rock against which he crouched, Kiopo
never stirred. Dusty Star watched with breathless excitement. He knew
that the wolf's stillness meant deadly danger to the unconscious Indian.
The latter came quickly on. In the intense silence the soft padding of
his deer-skin moccasins was plainly audible.

From where Dusty Star crouched, he was invisible to the Indian. So also
was Kiopo hidden by the rock. The boy saw at a glance that the man was
not of his own people, but belonged to the dreaded Yellow Dogs. Now the
Indian had almost reached the rocks. Dusty Star saw Kiopo's powerful
haunches quiver, and held his breath.

The next instant he saw the wolf's great body hurl itself through the
air.

Quick as lightning, the Indian leaped aside. Kiopo's terrible fangs
missed his throat by a finger's breadth. In a flash, the Indian's
tomahawk was out. Kiopo did not wait, and cleared the chasm with a
bound.

And now Dusty Star could see that several more Indians were coming down
the ledge. When they reached the spot where Kiopo had launched his
attack they stopped and examined the opposite bank carefully. Like Dusty
Star, Kiopo had drawn himself out of sight, among the thick mass of
brambles, and creepers.

The Indian who had been attacked could be seen pointing out to his
companions the exact point at which the wolf had disappeared. Dusty Star
watched them with a terrible fear growing moment by moment. If their
pursuers succeeded in making the crossing, he and Kiopo were only two
against five. At present, they were in a sort of rude cave formed by the
roots of the pine and screened by the hanging foliage; but in order to
continue their flight, it would be necessary to come out full in view of
their enemies and risk exposure to their deadly arrows.

They had not long to wait in suspense. They saw one of the Indians
prepare to take the leap.

Close against his side, Dusty Star could feel Kiopo's body shivering
with excitement.

Through the opening in the leaves, he saw an Indian lean back against
the rock as he himself had done in preparation for the spring. The next
instant Kiopo dashed through the opening with a snarl of fury.

Dusty Star saw him meet the Indian at the moment his feet touched the
rock. The
