means two bits, or twenty-five cents. He ain't worth more.” To look at Nack-yal had pleased Shefford very much indeed, but, once upon his back, he grew dubious. The mustang acted queer. He actually looked back at Shefford, and it was a look of speculation and disdain. Shefford took exception to Nack-yal's manner and to his reluctance to go, and especially to a habit the mustang had of turning off the trail to the left. Shefford had managed some rather spirited horses back in Illinois; and though he was willing and eager to learn all over again, he did not enjoy the prospect of Lake and Withers seeing this black mustang make a novice of him. And he guessed that was just what Nack-yal intended to do. However, once up over the hill, with Kayenta out of sight, Nack-yal trotted along fairly well, needing only now and then to be pulled back from his strange swinging to the left off the trail.
The pack-train traveled steadily and soon crossed the upland plain to descend into the valley again. Shefford saw the jagged red peaks with an emotion he could not name. The canyon between them were purple in the shadows, the great walls and slopes brightened to red, and the tips were gold in the sun. Shefford forgot all about his mustang and the trail.
Suddenly with a pound of hoofs Nack-yal seemed to rise. He leaped sidewise out of the trail, came down stiff-legged. Then Shefford shot out of the saddle. He landed so hard that he was stunned for an instant. Sitting up, he saw the mustang bent down, eyes and ears showing fight, and his forefeet spread. He appeared to be looking at something in the trail. Shefford got up and soon saw what had been the trouble. A long, crooked stick, rather thick and black and yellow, lay in the trail, and any mustang looking for an excuse to jump might have mistaken it for a rattlesnake. Nack-yal appeared disposed to be satisfied, and gave Shefford no trouble in mounting. The incident increased Shefford's dubiousness. These Arizona mustangs were unknown quantities.
Thereafter Shefford had an eye for the trail rather than the scenery, and this continued till the pack-train entered the mouth of the Sagi. Then those wonderful lofty cliffs, with their peaks and towers and spires, loomed so close and so beautiful that he did not care if Nack-yal did throw him. Along here, however, the mustang behaved well, and presently Shefford decided that if it had been otherwise he would have walked. The trail suddenly stood on end and led down into the deep wash, where some days before he had seen the stream of reddish water. This day there appeared to be less water and it was not so red. Nack-yal sank deep as he took short and careful steps down. The burros and other mustangs were drinking, and Nack-yal followed suit. The Indian, with a hand clutching his mustang's mane, rode up a steep, sandy slope on the other side that Shefford would not have believed any horse could climb. The burros plodded up and over the rim, with Withers calling to them. Joe Lake swung his rope and cracked the flanks of the gray mare and the red mule; and the way the two kicked was a revelation and a warning to Shefford. When his turn came to climb the trail he got off and walked, an action that Nack-yal appeared fully to appreciate.
From the head of this wash the trail wound away up the widening canyon, through greasewood flats and over grassy levels and across sandy stretches. The looming walls made the valley look narrow, yet it must have been half a mile wide. The slopes under the cliffs were dotted with huge stones and cedar-trees. There were deep indentations in the walls, running back to form box canyon, choked with green of cedar and spruce and pinon. These notches haunted Shefford, and he was ever on the lookout for more of them.
Withers came back to ride just in advance and began to talk.
“Reckon this Sagi canyon is your Deception Pass,” he said. “It's sure a queer hole. I've been lost more than once, hunting mustangs in here. I've an idea Nas Ta Bega knows all this country. He just pointed out a cliff-dwelling to me. See it? … There 'way up in that cave of the wall.”
Shefford saw a steep, rough slope leading up to a bulge of the cliff, and finally he made out strange little houses with dark, eyelike windows. He wanted to climb up there. Withers called his attention to more caves with what he believed were the ruins of cliff-dwellings. And as they rode along the trader showed him remarkable formations of rock where the elements were slowly hollowing out a bridge. They came presently to a region of intersecting canyon, and here the breaking of the trail up and down the deep washes took Withers back to his task with the burros and gave Shefford more concern than he liked with Nack-yal. The mustang grew unruly and was continually turning to the left. Sometimes he tried to climb the steep slope. He had to be pulled hard away from the opening canyon on the left. It seemed strange to Shefford that the mustang never swerved to the right. This habit of Nack-yal's and the increasing caution needed on the trail took all of Shefford's attention. When he dismounted, however, he had a chance to look around, and more and more he was amazed at the increasing proportions and wildness of the Sagi.
He came at length to a place where a fallen tree blocked the trail. All of the rest of the pack-train had jumped the log. But Nack-yal balked. Shefford dismounted, pulled the bridle over the mustang's head, and tried to lead him. Nack-yal, however, refused to budge. Whereupon Shefford got a stick and, remounting, he gave the balky mustang a cut across the flank. Then something violent happened. Shefford received a sudden propelling jolt, and then he was rising into the air, and then falling. Before he alighted he had a clear image of Nack-yal in the air above him, bent double, and seemingly possessed of devils. Then Shefford hit the ground with no light thud. He was thoroughly angry when he got dizzily upon his feet, but he was not quick enough to catch the mustang. Nack-yal leaped easily over the log and went on ahead, dragging his bridle. Shefford hurried after him, and the faster he went just by so much the cunning Nack-yal accelerated his gait. As the pack-train was out of sight somewhere ahead, Shefford could not call to his companions to halt his mount, so he gave up trying, and walked on now with free and growing appreciation of his surroundings.
The afternoon had waned. The sun blazed low in the west in a notch of the canyon ramparts, and one wall was darkening into purple shadow while the other shone through a golden haze. It was a weird, wild world to Shefford, and every few strides he caught his breath and tried to realize actuality was not a dream.
Nack-yal kept about a hundred paces to the fore and ever and anon he looked back to see how his new master was progressing. He varied these occasions by reaching down and nipping a tuft of grass. Evidently he was too intelligent to go on fast enough to be caught by Withers. Also he kept continually looking up the slope to the left as if seeking a way to climb out of the valley in that direction. Shefford thought it was well the trail lay at the foot of a steep slope that ran up to unbroken bluffs.
The sun set and the canyon lost its red and its gold and deepened its purple. Shefford calculated he had walked five miles, and though he did not mind the effort, he would rather have ridden Nack-yal into camp. He mounted a cedar ridge, crossed some sandy washes, turned a corner of bold wall to enter a wide, green level. The mustangs were rolling and snorting. He heard the bray of a burro. A bright blaze of camp-fire greeted him, and the dark figure of the Indian approached to intercept and catch Nack-yal. When he stalked into camp Withers wore a beaming smile, and Joe Lake, who was on his knees making biscuit dough in a pan, stopped proceedings and drawled:
“Reckon Nack-yal bucked you off.”
“Bucked! Was that it? Well, he separated himself from me in a new and somewhat painful manner—to me.”
“Sure, I saw that in his eye,” replied Lake; and Withers laughed with him.
“Nack-yal never was well broke,” he said. “But he's a good mustang, nothing like Joe's Navvy or that gray mare Dynamite. All this Indian stock will buck on a man once in a while.”
“I'll take the bucking along with the rest,” said Shefford. Both men liked his reply, and the Indian smiled for the first time.
Soon they all sat round a spread tarpaulin and ate like wolves. After supper came the rest and talk before the camp-fire. Joe Lake was droll; he said the most serious things in a way to make Shefford wonder if he was not joking. Withers
