and disappearing as they bounded awkwardly along; while the antelope,
with the simple curiosity peculiar to them, would often approach as
closely, their little horns and white throats just visible above the
grass tops, as they gazed eagerly at us with their round black eyes.

I dismounted, and amused myself with firing at the wolves. Henry
attentively scrutinized the surrounding landscape; at length he gave a
shout, and called on me to mount again, pointing in the direction of the
sand-hills. A mile and a half from us, two minute black specks
slowly traversed the face of one of the bare glaring declivities, and
disappeared behind the summit. "Let us go!" cried Henry, belaboring the
sides of Five Hundred Dollar; and I following in his wake, we galloped
rapidly through the rank grass toward the base of the hills.

From one of their openings descended a deep ravine, widening as it
issued on the prairie. We entered it, and galloping up, in a moment were
surrounded by the bleak sand-hills. Half of their steep sides were bare;
the rest were scantily clothed with clumps of grass, and various uncouth
plants, conspicuous among which appeared the reptile-like prickly-pear.
They were gashed with numberless ravines; and as the sky had suddenly
darkened, and a cold gusty wind arisen, the strange shrubs and the
