Shefford slid down upon a gra.s.sy bank, and finding the tracks of the horses, he followed them. They led along the wall. As soon as he had a.s.sured himself that Nas Ta Bega had gone down the canon he abandoned the tracks and pushed ahead swiftly. He heard the soft rush of running water. In the center of the canon wound heavy lines of bright-green foliage, bordering a rocky brook. The air was close, warm, and sweet with perfume of flowers. The walls were low and shelving, and soon lost that rounded appearance peculiar to the wind-worn slopes above. Shefford came to where the horses had plowed down a gravelly bank into the clear, swift water of the brook. The little pools of water were still muddy.

Shefford drank, finding the water cold and sweet, without the bitter bite of alkali. He crossed and pushed on, running on the gra.s.sy levels.

Flowers were everywhere, but he did not notice them particularly. The canon made many leisurely turns, and its size, if it enlarged at all, was not perceptible to him yet. The rims above him were perhaps fifty feet high. Cottonwood-trees began to appear along the brook, and blossoming buck-brush in the corners of wall.

He had traveled perhaps a mile when Nas Ta Bega, appearing to come out of the thicket, confronted him.

"h.e.l.lo!" called Shefford. "Where're Fay--and the others?"

The Indian made a gesture that signified the rest of the party were beyond a little way. Shefford took Nas Ta Bega's arm, and as they walked, and he panted for breath, he told what had happened back on the slopes.

The Indian made one of his singular speaking sweeps of hand, and he scrutinized Shefford's face, but he received the news in silence. They turned a corner of wall, crossed a wide, shallow, boulder-strewn place in the brook, and mounted the bank to a thicket. Beyond this, from a clump of cottonwoods, La.s.siter strode out with a gun in each hand. He had been hiding.

"Sh.o.r.e I'm glad to see you," he said, and the eyes that piercingly fixed on Shefford were now as keen as formerly they had been mild.

"Gone! La.s.siter--they're gone," broke out Shefford. "Where's Fay--and Jane?"

La.s.siter called, and presently the women came out of the thick brake, and Fay bounded forward with her swift stride, while Jane followed with eager step and anxious face. Then they all surrounded Shefford.

"It was Shadd--and his gang," panted Shefford. "Eight in all. Three or four Piutes--the others outlaws. They lost track of us. Went below the place--where they shot at us. And they came up--on a bad slope."

Shefford described the slope and the deep chasm and how Shadd led up to the point where he saw his mistake and then how the catastrophe fell.

"I shot--and missed," repeated Shefford, with the sweat in beads on his pale face. "I missed Shadd. Maybe I hit the horse. He plunged--reared--fell back--a terrible fall--right upon that bunch of horses and men below.... In a horrible, wrestling, screaming tangle they slid over the rim! I don't know how many. I saw some men running along.

I saw three other horses plunging. One slipped and went over. ... I have no idea how many, but Shadd and some of his gang went to destruction."

"Sh.o.r.e thet's fine!" said La.s.siter. "But mebbe I won't get to use them guns, after all."

"Hardly on that gang," laughed Shefford. "The two Piutes and what others escaped turned back. Maybe they'll meet a posse of Mormons--for of course the Mormons will track us, too--and come back to where Shadd lost his life. That's an awful place. Even the Piute got lost--couldn't follow Nas Ta Bega. It would take any pursuers some time to find how we got in here. I believe we need not fear further pursuit. Certainly not to-night or to-morrow. Then we'll be far down the canon."

When Shefford concluded his earnest remarks the faces of Fay and Jane had lost the signs of suppressed dread.

"Nas Ta Bega, make camp here," said Shefford. "Water--wood--gra.s.s--why, this 's something like.... Fay, how's your arm?"

"It hurts," she replied, simply.

"Come with me down to the brook and let me wash and bind it properly."

They went, and she sat upon a stone while he knelt beside her and untied his scarf from her arm. As the blood had hardened, it was necessary to slit her sleeve to the shoulder. Using his scarf, he washed the blood from the wound, and found it to be merely a cut, a groove, on the surface.

"That's nothing," Shefford said, lightly. "It'll heal in a day. But there'll always be a scar. And when we--we get back to civilization, and you wear a pretty gown without sleeves, people will wonder what made this mark on your beautiful arm."

Fay looked at him with wonderful eyes. "Do women wear gowns without sleeves?" she asked.

"They do."

"Have I a--beautiful arm?"

She stretched it out, white, blue-veined, the skin fine as satin, the lines graceful and flowing, a round, firm, strong arm.

"The most beautiful I ever saw," he replied.

But the pleasure his compliment gave her was not communicated to him.

His last impression of that right arm had been of its strength, and his mind flashed with lightning swiftness to a picture that haunted him--Waggoner lying dead on the porch with that powerfully driven knife in his breast. Shefford shuddered through all his being. Would this phantom come often to him like that? Hurriedly he bound up her arm with the scarf and did not look at her, and was conscious that she felt a subtle change in him.

The short twilight ended with the fugitives comfortable in a camp that for natural features could not have been improved upon. Darkness found Fay and Jane asleep on a soft mossy bed, a blanket tucked around them, and their faces still and beautiful in the flickering camp-fire light.

La.s.siter did not linger long awake. Nas Ta Bega, seeing Shefford's excessive fatigue, urged him to sleep. Shefford demurred, insisting that he share the night-watch. But Nas Ta Bega, by agreeing that Shefford might have the following night's duty, prevailed upon him.

Shefford seemed to shut his eyes upon darkness and to open them immediately to the light. The stream of blue sky above, the gold tints on the western rim, the rosy, brightening colors down in the canon, were proofs of the sunrise. This morning Nas Ta Bega proceeded leisurely, and his manner was comforting. When all was in readiness for a start he gave the mustang he had ridden to Shefford, and walked, leading the pack-animal.

The mode of travel here was a selection of the best levels, the best places to cross the brook, the best banks to climb, and it was a process of continual repet.i.tion. As the Indian picked out the course and the mustangs followed his lead there was nothing for Shefford to do but take his choice between reflection that seemed predisposed toward gloom and an absorption in the beauty, color, wildness, and changing character of Nonnezoshe Boco.

a.s.suredly his experience in the desert did not count in it a trip down into a strange, beautiful, lost canon such as this. It did not widen, though the walls grew higher. They began to lean and bulge, and the narrow strip of sky above resembled a flowing blue river. Huge caverns had been hollowed out by some work of nature, what, he could not tell, though he was sure it could not have been wind. And when the brook ran close under one of these overhanging places the running water made a singular, indescribable sound. A crack from a hoof on a stone rang like a hollow bell and echoed from wall to wall. And the croak of a frog--the only living creature he had so far noted in the canon--was a weird and melancholy thing.

Fay rode close to him, and his heart seemed to rejoice when she spoke, when she showed how she wanted to be near him, yet, try as he might, he could not respond. His speech to her--what little there was--did not come spontaneously. And he suffered a remorse that he could not be honestly natural to her. Then he would drive away the encroaching gloom, trusting that a little time would dispel it.

"We are deeper down than Surprise Valley," said Fay.

"How do you know?" he asked.

"Here are the pink and yellow sago-lilies. You remember we went once to find the white ones? I have found white lilies in Surprise Valley, but never any pink or yellow."

Shefford had seen flowers all along the green banks, but he had not marked the lilies. Here he dismounted and gathered several. They were larger than the white ones of higher alt.i.tudes, of the same exquisite beauty and fragility, of such rare pink and yellow hues as he had never seen. He gave the flowers to Fay.

"They bloom only where it's always summer," she said.

That expressed their nature. They were the orchids of the summer canon.

They stood up everywhere starlike out of the green. It was impossible to prevent the mustangs treading them under hoof. And as the canon deepened, and many little springs added their tiny volume to the brook, every gra.s.sy bench was dotted with lilies, like a green sky star-spangled. And this increasing luxuriance manifested itself in the banks of purple moss and clumps of lavender daisies and great cl.u.s.ters of yellow violets. The brook was lined by blossoming buck-rush; the rocky corners showed the crimson and magenta of cactus; ledges were green with shining moss that sparkled with little white flowers. The hum of bees filled the air.

But by and by this green and colorful and verdant beauty, the almost level floor of the canon, the banks of soft earth, the thickets and the clumps of cotton-woods, the shelving caverns and the bulging walls--these features gradually were lost, and Nonnezoshe Boco began to deepen in bare red and white stone steps, the walls sheered away from one another, breaking into sections and ledges, and rising higher and higher, and there began to be manifested a dark and solemn concordance with the nature that had created this rent in the earth.

There was a stretch of miles where steep steps in hard red rock alternated with long levels of round boulders. Here one by one the mustangs went lame. And the fugitives, dismounting to spare the faithful beasts, slipped and stumbled over these loose and treacherous stones.

Fay was the only one who did not show distress. She was glad to be on foot again and the rolling boulders were as stable as solid rock for her.

The hours pa.s.sed; the toil increased; the progress diminished; one of the mustangs failed entirely and was left; and all the while the dimensions of Nonnezoshe Boco magnified and its character changed. It became a thousand-foot walled canon, leaning, broken, threatening, with great yellow slides blocking pa.s.sage, with huge sections split off from the main wall, with immense dark and gloomy caverns. Strangely, it had no intersecting canon. It jealously guarded its secret. Its unusual formations of cavern and pillar and half-arch led the mind to expect any monstrous stone-shape left by an avalanche or cataclysm.

Down and down the fugitives toiled. And now the stream-bed was bare of boulders, and the banks of earth. The floods that had rolled down that canon had here borne away every loose thing. All the floor was bare red and white stone, polished, glistening, slippery, affording treacherous foothold. And the time came when Nas Ta Bega abandoned the stream-bed to take to the rock-strewn and cactus-covered ledges above.

Jane gave out and had to be a.s.sisted upon the weary mustang. Fay was persuaded to mount Nack-yal again. La.s.siter plodded along. The Indian bent tired steps far in front. And Shefford traveled on after him, footsore and hot.

The canon widened ahead into a great, ragged, iron-hued amphitheater, and from there apparently turned abruptly at right angles. Sunset rimmed the walls. Shefford wondered dully when the Indian would halt to camp.

And he dragged himself onward with eyes down on the rough ground.

When he raised them again the Indian stood on a point of slope with folded arms, gazing down where the canon veered. Something in Nas Ta Bega's pose quickened Shefford's pulse and then his steps. He reached the Indian and the point where he, too, could see beyond that vast jutting wall that had obstructed his view.

A mile beyond all was bright with the colors of sunset, and spanning the canon in the graceful shape arid beautiful hues of a rainbow was a magnificent stone bridge.

"Nonnezoshe!" exclaimed the Navajo, with a deep and sonorous roll in his voice.
