flung back his head, and from his thin,
Indian boyish lips there issued a weird, prolonged howl. He was
answering the wolf in his own language.

"Great guns!" ejaculated one of the highwaymen, "that wolf's right under
our feet. There he goes now. I hear him prowling past." For with the
howl, Leloo had started his cayuse gently, and the wise creature was
slipping beneath the dreaded boulder almost noiselessly. The boy fairly
held his breath. Suppose they should peer through the dark, and see that
it was a horse and rider, and no wild animal padding up the trail? Then
his wolf friend from the heights answered him, and Leloo once more
lifted his head, and the strange half-barking, half-sobbing cry again
broke the silence. He was well past the boulder now, ten, twenty, thirty
yards, when his innocent little cayuse gave that peculiar snort which a
horse always gives when some sudden fear or danger threatens. The
animal's instinct had evidently detected the presence of enemies.

"It's a horseman, not a wolf," fairly yelled a voice behind him; but
Leloo had already struck the cayuse a smart blow on the flank, at which
the animal bunched its four hoofs together, shivered, snorted again,
then plunged, galloping like mad down the trail, down, blindly down into
the darkness ahead. One, two, three sharp revolver shots rang out behind
him, the bullets falling wide of their mark in the blackness of the
night, rapidly running feet that seemed to gain upon him, the crash of
a falling man, then terrible language--all rang in his ears in quick
succession, but the boy never drew rein, never halted. On plunged the
horse, heedlessly, wildly, but Leloo stuck to his back, scorning the
fear of a horrible death in the canyon below, thinking only of the
danger of the treasure-laden stage and of the safety of Big Bill, the
driver, whom his father loved, and whom every Indian of the Lillooet
tribe respected.

The stones were now rattling from the rush of his horse's hoofs, and
once or twice the boy held his breath, as they swung round a boulder in
the dark, and the sturdy animal almost lost its balance. Sometimes he
heard the robbers scrambling down the trail far above him, the trail
he had already covered, and twice they fired on him; but the kindly
darkness saved him. He was nearing the foot of the mountain now, and the
cayuse was beginning to heave badly, but Leloo still struck the sweating
flanks, and the creature still plunged on, until, fi
