The reverent awe with which she had always viewed the valley was as strong in her today as it had ever been—stronger, in fact, because she had not seen the place for some time, and because in her heart there now dwelt a sadness that had not been there in those other days—at least since her mother had died.

She was high above the floor of the valley; and she could see the main trail below her weaving around low mounds and sinking into depressions; disappearing into timber groves, reappearing farther on, disappearing again, and again reappearing until it grew blurred and indistinct in her vision.

In the marvelous clarity of the atmosphere this morning every beauteous feature of the valley was disclosed to her inspection. The early morning haze had lifted, and the few fleecy clouds that floated in the blue bowl of sky were motionless, their majestic billows glowing in the sun. She saw a Mexican eagle swoop over the cloud, sailing on slow wing high above it, and growing so distant in her vision that he became a mere speck moving in the limitless expanse of space.

It was a colossal landscape, and its creator had neglected no detail. And it was harmonious, from the emerald green that carpeted the floor of the valley near the gleaming river to the gigantic shoulders of the rugged hills that lifted their huge, bastioned walls into the blue of the sky. Some tall rock spires that thrust their peaks skyward far over on the southern side of the valley had always interested her; they seemed to be sentinels that guarded the place, hinting of an ages-old mystery that seemed to reign all about them.

But there was mystery in everything in the valley, she felt; for it lay before her, spreading, slumbrous, basking in the brilliant sunlight—seeming to wait, as it seemed to have waited from the dawn of the first day, for man to wonder over it.

She saw the Mexican eagle again after a while. It was making a wide circle beyond the rock spires, floating lazily above them in long, graceful swoops that were so lacking in effort that she longed to be up there with him—to ride the air with him, to feel the exhilaration he must feel.

As she looked, however, she caught a faint blur on the southern horizon of the big picture—a yellowish-black cloud that hugged the horizon and traveled rapidly eastward. It was some time before she realized that what she saw was a dust cloud, and there were men in it—horsemen.

She got up from the rock, her face slowly whitening. And into her heart came a presentiment that those men in the dust cloud were abroad upon an errand of evil.

No doubt the presentiment was caused from the dread and fear she had lived under for days—the consciousness that Deveny was in the valley, and a recollection of the warnings that Harlan had given her. And she knew the horsemen could not be Rancho Seco men—for they had gone southward from the ranch, and there was no grass range where the horsemen were riding. Also, the men were riding eastward, toward the Rancho Seco.

Trembling a little with apprehension, she mounted Billy and sent him down the slope to the floor of the valley. The descent was hazardous, and Billy did not make good time, but when he reached the level at the foot of the slope he stretched his neck and fell into a steady, rapid pace that took him down the valley swiftly.
