But don't let Grace look. She will want to capture them all and
keep them for pets."

But Nan was looking in another direction. Along the western horizon
a dull, slate-colored cloud was slowly rising. Nan wondered if it
was dust, and if it was caused by the hoofs of cattle or horses. It
was a curious looking cloud.




CHAPTER XX

THE ANTELOPE HUNT; AND MORE


The little party approached with caution the spot where the
antelopes were feeding. Rhoda was no amateur; and she advised her
friends to ride quietly, to make no quick motions, and as far as
possible to ride along the edge of the rising ground.

Of course, the wind was blowing from the antelopes; otherwise the
party would never have got near them at all. The creatures were
feeding so far out on the plain that it would, too, be unwise to
try to creep up on them behind the rocks and bushes among which the
cavalcade now rode.

"When we get somewhat nearer, we shall have to ride right out into
plain sight and run them down," Rhoda said. "That is our best
chance."
