din, of the
terror-stricken jumping mob, of the ever-starting, ever-widening streams
of sheep; he rode and yelled and fired his Colt. The dust choked him,
the sun burned him, the flying pebbles cut his cheek. Once he had a
glimpse of Black Bolly in a melee of dust and sheep; Dave's mustang
blurred in his sight; August's roan seemed to be double. Then
Silvermane, of his own accord, was out before them all.

The sheep had almost gained the victory; their keen noses were pointed
toward the water; nothing could stop their flight; but still the drivers
dashed at them, ever fighting, never wearying, never ceasing.

At the last incline, where a gentle slope led down to a dark break in
the desert, the rout became a stampede. Left and right flanks swung
round, the line lengthened, and round the struggling horses, knee-deep
in woolly backs, split the streams to flow together beyond in one
resistless river of sheep. Mescal forced Bolly out of danger; Dave
escaped the right flank, August and Hare swept on with the flood, till
the horses, sighting the dark canyon, halted to stand like rocks.

"Will they run over the rim?" yelled Hare, horrified. His voice came to
him as a whisper. August Naab, sweat-stained in red dust, haggard, gray
locks streaming in the wind, raised his arms above his head, hopeless.

The long nodding line of woolly forms, lifting like the crest of a
yellow wave, plunged out and down in rounded billow over the canyon
rim. With din of hoofs and bleats the sheep spilled themselves over the
precipice, and an awful deafening roar boomed up from the river, like
the spreading thunderous crash of an avalanche.

How endless seemed that fatal plunge! The last line of sheep, pressing
close to those gone before, and yet impelled by the strange instinct of
life, turned their eyes too late on the brink, carried over by their own
momentum.

The sliding roar ceased; its echo, muffled and hollow, pealed from the
cliffs, then rumbled down the canyon to merge at length in the sullen,
dull, continuous sound of the rapids.

Hare turned at last from that narrow iron-walled cleft, the depth of
which he had not seen, and now had no wish to see; and his eyes fell
upon a little Navajo lamb limping in the trail of the flock, headed for
the canyon, as sure as its mother in purpose. He dismounted and seized
it to find, to his infinite wonder and gladness, that it wore a string
and bell round its neck. It was Mescal's pet.
