Where had the girl been born--what had her life been? Shefford was intensely curious about her. She seemed as different from any other women he had known as this rare canon lily was different from the tame flowers at home.

On the return up the slope she outstripped him. She climbed lightly and tirelessly. When he reached her upon the promontory there was a stain of red in her cheeks and her expression had changed.

"Let's go back up over the rocks," she said. "I've not climbed for--for so long."

"I'll go where you go," he replied.

Then she was off, and he followed. She took to the curves of the bare rocks and climbed. He sensed a spirit released in her. It was so strange, so keen, so wonderful to be with her, and when he did catch her he feared to speak lest he break this mood. Her eyes grew dark and daring, and often she stopped to look away across the wavy sea of stones to something beyond the great walls. When they got high the wind blew her hair loose and it flew out, a golden stream, with the sun bright upon it. He saw that she changed her direction, which had been in line with the two peaks, and now she climbed toward the heights. They came to a more difficult ascent, where the stone still held to the smooth curves, yet was marked by steep bulges and slants and crevices. Here she became a wild thing. She ran, she leaped, she would have left him far behind had he not called. Then she appeared to remember him and waited.

Her face had now lost its whiteness; it was flushed, rosy, warm.

"Where--did you--ever learn--to run over rocks--this way?" he panted.

"All my life I've climbed," she said. "Ah! it's so good to be up on the walls again--to feel the wind--to see!"

Thereafter he kept close to her, no matter what the effort. He would not miss a moment of her, if he could help it. She was wonderful. He imagined she must be like an Indian girl, or a savage who loved the lofty places and the silence. When she leaped she uttered a strange, low, sweet cry of wildness and exultation. Shefford guessed she was a girl freed from her prison, forgetting herself, living again youthful hours. Still she did not forget him. She waited for him at the bad places, lent him a strong hand, and sometimes let it stay long in his clasp. Tireless and agile, sure-footed as a goat, fleet and wild she leaped and climbed and ran until Shefford marveled at her. This adventure was indeed fulfilment of a dream. Perhaps she might lead him to the treasure at the foot of the rainbow. But that thought, sad with memory daring forth from its grave, was irrevocably linked with a girl who was dead. He could not remember her, in the presence of this wonderful creature who was as strange as she was beautiful. When Shefford reached for the brown hand stretched forth to help him in a leap, when he felt its strong clasp, the youth and vitality and life of it, he had the fear of a man who was running towards a precipice and who could not draw back. This was a climb, a lark, a wild race to the Mormon girl, bound now in the village, and by the very freedom of it she betrayed her bonds. To Shefford it was also a wild race, but toward one sure goal he dared not name.

They went on, and at length, hand in hand, even where no steep step or wide fissure gave reason for the clasp. But she seemed unconscious. They were nearing the last height, a bare eminence, when she broke from him and ran up the smooth stone. When he surmounted it she was standing on the very summit, her arms wide, her full breast heaving, her slender body straight as an Indian's, her hair flying in the wind and blazing in the sun. She seemed to embrace the west, to reach for something afar, to offer herself to the wind and distance. Her face was scarlet from the exertion of the climb, and her broad brow was moist. Her eyes had the piercing light of an eagle's, though now they were dark. Shefford instinctively grasped the essence of this strange spirit, primitive and wild. She was not the woman who had met him at the spring. She had dropped some side of her with that Mormon hood, and now she stood totally strange.

She belonged up here, he divined. She was a part of that wildness. She must have been born and brought up in loneliness, where the wind blew and the peaks loomed and silence held dominion. The sinking sun touched the rim of the distant wall, and as if in parting regret shone with renewed golden fire. And the girl was crowned as with a glory.

Shefford loved her then. Realizing it, he thought he might have loved her before, but that did not matter when he was certain of it now.

He trembled a little, fearfully, though without regret. Everything pertaining to his desert experience had been strange--this the strangest of all.

The sun sank swiftly, and instantly there was a change in the golden light. Quickly it died out. The girl changed as swiftly. She seemed to remember herself, and sat down as if suddenly weary. Shefford went closer and seated himself beside her.

"The sun has set. We must go," she said. But she made no movement.

"Whenever you are ready," replied he.

Just as the blaze had died out of her eyes, so the flush faded out of her face. The whiteness stole back, and with it the sadness. He had to bite his tongue to keep from telling her what he felt, to keep from pouring out a thousand questions. But the privilege of having seen her, of having been with her when she had forgotten herself--that he believed was enough. It had been wonderful; it had made him love her But it need not add to the tragedy of her life, whatever that was. He tried to eliminate himself. And he watched her.

Her eyes were fixed upon the gold-rimmed ramparts of the distant wall in the west. Plain it was how she loved that wild upland. And there seemed to be some haunting memory of the past in her gaze--some happy part of life, agonizing to think of now.

"We must go," she said, and rose.

Shefford rose to accompany her. She looked at him, and her haunting eyes seemed to want him to know that he had helped her to forget the present, to remember girlhood, and that somehow she would always a.s.sociate a wonderful happy afternoon with him. He divined that her silence then was a Mormon seal on lips.

"Mary, this has been the happiest, the best, the most revealing day of my life," he said, simply.

Swiftly, as if startled, she turned and faced down the slope. At the top of the wall above the village she put on the dark hood, and with it that somber something which was Mormon.

Twilight had descended into the valley, and shadows were so thick Shefford had difficulty in finding Mary's bucket. He filled it at the spring, and made offer to carry it home for her, which she declined.

"You'll come to-night--later?" she asked.

"Yes," he replied, hurriedly promising. Then he watched her white form slowly glide down the path to disappear in the shadows.

Nas Ta Bega and Joe were busy at the camp-fire. Shefford joined them.

This night he was uncommunicative. Joe peered curiously at him in the flare of the blaze. Later, after the meal, when Shefford appeared restless and strode to and fro, Joe spoke up gruffly:

"Better hang round camp to-night."

Shefford heard, but did not heed. Nevertheless, the purport of the remark, which was either jealousy or admonition, haunted him with the possibility of its meaning.

He walked away from the camp-fire, under the dark pinyons, out into the starry open; and every step was hard to take, unless it pointed toward the home of the girl whose beauty and sadness and mystery had bewitched him. After what seemed hours he took the well-known path toward her cabin, and then every step seemed lighter. He divined he was rushing to some fate--he knew not what.

The porch was in shadow. He peered in vain for the white form against the dark background. In the silence he seemed to hear his heart-beats thick and m.u.f.fled.

Some distance down the path he heard the sound of hoofs. Withdrawing into the gloom of a cedar, he watched. Soon he made out moving horses with riders. They filed past him to the number of half a score. Like a flash of fire the truth burned him. Mormons come for one of those mysterious night visits to sealed wives!

Shefford stalked far down the valley, into the lonely silence and the night shadows under the walls.

VIII. THE HOGAN OF NAS TA BEGA

The home of Nas Ta Bega lay far up the cedared slope, with the craggy yellow cliffs and the black canon and the pine-fringed top of Navajo Mountain behind, and to the fore the vast, rolling descent of cedar groves and sage flats and sandy washes. No dim, dark range made bold outline along the horizon; the stretch of gray and purple and green extended to the blue line of sky.

Down the length of one sage level Shefford saw a long lane where the brush and the gra.s.s had been beaten flat. This, the Navajo said, was a track where the young braves had raced their mustangs and had striven for supremacy before the eyes of maidens and the old people of the tribe.

"Nas Ta Bega, did you ever race here?" asked Shefford.

"I am a chief by birth. But I was stolen from my home, and now I cannot ride well enough to race the braves of my tribe," the Indian replied, bitterly.

In another place Joe Lake halted his horse and called Shefford's attention to a big yellow rock lying along the trail. And then he spoke in Navajo to the Indian.

"I've heard of this stone--Isende Aha," said Joe, after Nas Ta Bega had spoken. "Get down, and let's see." Shefford dismounted, but the Indian kept his seat in the saddle.

Joe placed a big hand on the stone and tried to move it. According to Shefford's eye measurement the stone was nearly oval, perhaps three feet high, by a little over two in width. Joe threw off his sombrero, took a deep breath, and, bending over, clasped the stone in his arms. He was an exceedingly heavy and powerful man, and it was plain to Shefford that he meant to lift the stone if that were possible. Joe's broad shoulders strained, flattened; his arms bulged, his joints cracked, his neck corded, and his face turned black. By gigantic effort he lifted the stone and moved it about six inches. Then as he released his hold he fell, and when he sat up his face was wet with sweat.

"Try it," he said to Shefford, with his lazy smile. "See if you can heave it."

Shefford was strong, and there had been a time when he took pride in his strength. Something in Joe's supreme effort and in the gloom of the Indian's eyes made Shefford curious about this stone. He bent over and grasped it as Joe had done. He braced himself and lifted with all his power, until a red blur obscured his sight and shooting stars seemed to explode in his head. But he could not even stir the stone.

"Shefford, maybe you'll be able to heft it some day," observed Joe. Then he pointed to the stone and addressed Nas Ta Bega.

The Indian shook his head and spoke for a moment.

"This is the Isende Aha of the Navajos," explained Joe. "The young braves are always trying to carry this stone. As soon as one of them can carry it he is a man. He who carries it farthest is the biggest man. And just so soon as any Indian can no longer lift it he is old. Nas Ta Bega says the stone has been carried two miles in his lifetime. His own father carried it the length of six steps."

"Well! It's plain to me that I am not a man," said Shefford, "or else I am old."

Joe Lake drawled his lazy laugh and, mounting, rode up the trail. But Shefford lingered beside the Indian.

"Bi Nai," said Nas Ta Bega, "I am a chief of my tribe, but I have never been a man. I never lifted that stone. See what the pale-face education has done for the Indian!"
