of that terrible stitch in her side. If it returned she knew she would
fall off. But, fortunately, just when she was growing weak and dizzy,
the horses ahead slowed to a walk on a descent. The road wound down into
a wide deep canyon. Carley had a respite from her severest pains. Never
before had she known what it meant to be so grateful for relief from
anything.

The afternoon grew far advanced and the sunset was hazily shrouded in
gray. Hutter did not like the looks of those clouds. "Reckon we're in
for weather," he said. Carley did not care what happened. Weather or
anything else that might make it possible to get off her horse! Glenn
rode beside her, inquiring solicitously as to her pleasure. "Ride of
my life!" she lied heroically. And it helped some to see that she both
fooled and pleased him.

Beyond the canyon the cedared desert heaved higher and changed its
aspect. The trees grew larger, bushier, greener, and closer together,
with patches of bleached grass between, and russet-lichened rocks
everywhere. Small cactus plants bristled sparsely in open places;
and here and there bright red flowers--Indian paintbrush, Flo called
them--added a touch of color to the gray. Glenn pointed to where dark
banks of cloud had massed around the mountain peaks. The scene to the
west was somber and compelling.

At last the men and the pack-horses ahead came to a halt in a level
green forestland with no high trees. Far ahead a chain of soft gray
round hills led up to the dark heaved mass of mountains. Carley saw the
gleam of water through the trees. Probably her mustang saw or scented
it, because he started to trot. Carley had reached a limit of strength,
endurance, and patience. She hauled him up short. When Spillbeans
evinced a stubborn intention to go on Carley gave him a kick. Then it
happened.

She felt the reins jerked out of her hands and the saddle propel her
upward. When she descended it was to meet that before-experienced jolt.

"Look!" cried Flo. "That bronc is going to pitch."

"Hold on, Carley!" yelled Glenn.

Desperately Carley essayed to do just that. But Spillbeans jolted her
out of the saddle. She came down on his rump and began to slide back and
down. Frightened and furious, Carley tried to hang to the saddle with
her hands and to squeeze the mustang with her knees. But another jolt
broke her hold, and then, helpless and bewildered, with her heart in
her throat and a terrible sensation of weakness
