kered softly. Waring rose and led the horse to water, and,
returning, emptied half the grain in the morral on a blanket. Dex
munched contentedly. When the horse had finished eating the grain,
Waring picketed him in a fresh spot and climbed back to the ledge, where
he sat watching the western wall of the canon, occasionally glancing up
as some dim star burned through the deepening dusk and bloomed to a
silvery maturity.
Presently a faint pallor overspread the canon till it lay like a ghostly
sea dotted with strange islands of brush and rock; islands that seemed
to waver and shift in a sort of vague restlessness, as though trying to
evade the ever-brightening tide of moonlight that burned away their
shrouds of dusk and fixed them in still, tangible shapes upon the canon
floor.
Across the canon the farther trail ran past a broad, blank wall of rock.
No horseman could cross that open space unseen. Waring, seated upon the
ledge, leaned back against the wall, watching the angling shadows
shorten as the moon drew overhead. Toward morning he became drowsy. As
the white radiance paled to gray, he rose and paced back and forth upon
the narrow ledge to keep himself awake. In a few minutes the moon would
disappear behind the farther rim of the world; the canon would sink back
into its own night, all its moonlit imageries melting, vanishing. In the
hour before dawn Waring would be unable to see anything of the farther
wall save a wavering blur.
Just below him he could discern the outline of his horse, with head
lowered, evidently dozing. Having in mind the keenness of desert-bred
stock, he watched the horse. The minutes drifted by. The horse seemed
more distinct. Waring thought he could discern the picket rope. He
endeavored to trace it from horse to picket. Foot by foot his eyes
followed its slack outline across the ground. The head of the metal
picket glimmered faintly. Waring closed his eyes, nodded, and caught
himself. This time he traced the rope from picket to horse. It seemed a
childish thing to do, yet it kept him awake. Did he imagine it, or had
the rope moved?
Dex had lifted his head. He was sniffing the cool morning air. Slowly
the tawny-golden shape of the big buckskin turned, head up and nostrils
rounded in tense rings. Waring glanced across the canon. The farther
wall was still dim in the half-light. In a few minutes the trail would
become distinct. Dropping from the ledge, he stepped to his saddle. Dex
