she spoke as evenly as if she were sitting in a
rocking chair.

"You'll be used to it in a moment," she assured him.

He learned, indeed, that if one pressed the stirrups as the shoulders of
the horse swung down and leaned a trifle forward when the shoulders rose
again, the motion ceased to be jarring; for she was truly a matchless
creature and gaited like one of those fabulous horses of old, sired by
the swift western wind. In a little time a certain pride went beating
through the veins of the doctor, the air blew more deeply into his
lungs, there was a different tang to the wind and a different feel to
the sun--a peculiar richness of yellow warmth. And the small head of the
horse and the short, sharp, pricking ears tossed continually; and now
and then the mare threw her head a bit to one side and glanced back at
him with what he felt to be a reassuring air. Life and strength and
speed were gripped between his knees--he flashed a glance at the girl.

But she rode with face straightforward and there was that about her
which made him turn his eyes suddenly away and look far off. It was a
jagged country, for in the brief rainy season there came sudden and
terrific downpours which lashed away the soil and scoured the face of
the underlying rock, and in a single day might cut a deep arroyo where

struggle--and there in the distance were the spectator mountains. High,
lean-flanked mountains they were, not clad in forests, but rather
bristling with a stubby growth of the few trees which might endure in
precarious soil and bitter weather, but now they gathered the dignity of
distance about them. The grass of the foothills was a faint green mist
about their feet, cloaks of exquisite blue hung around the upper masses,
but their heads were naked to the pale skies. And all day long, with
deliberate alteration, the garb of the mountains changed. When the
