The men also turned away, but continued their excited talk. But even they after a time relapsed into silence. What it was all about Pat did not know. He knew it was something very serious, and suddenly fear came to him. He saw some of the men lie down as if to sleep, and he feared that they intended to remain here for ever, in this place absolutely destitute of herbage. But after a time, made sluggish by the attitude of the men, he himself attempted to drowse. But the heat pulsating up off the rocks discouraged him, and he soon abandoned the attempt, standing motionless in the hot sun.

A change came over him. He took to brooding over his many discomforts–hunger pangs, loss of sleep, bothersome flies, the pain of his swollen ankles. As the day advanced his ankles swelled more, and grew worse, the flies became more troublesome, and his inner gnawings more pronounced. So the time went on and he brooded through the still watches of the afternoon, through the soft stirrings of evening, on into night again. With the coming of night light breezes rose from the spaces below to spur his fevered body into something of its wonted vigor. And the night brought also preparations among the men to journey on. This he welcomed, even more than the cooling zephyrs.

There was some delay. His master entered upon a dispute with the horseless man. The voices became excited and rose to vehement heights. But presently they subsided when Pat himself, anxious to be active, sounded a note of protest. Yet the argument proved to his benefit. Instead of mounting him behind his master, the odd man swung up behind another man on the sorrel. Then he was permitted to move forward, and as he approached the narrow defile he sounded another nicker, now of gratification.

The pass dropped almost sheer in places. As he descended, more than once he was compelled to slide on stiffened legs. In this at first he felt ecstatic danger thrills. But only at first. Soon he wearied of it, and he was glad when he struck the bottom, where, after being guided out of shadow and into broad moonlight, he found himself moving to the west in a deep canyon. With the other horses he burst into a canter, and continued at a canter hour after hour, following the winding and twisting canyon until daylight, with its shadows creeping away before him, revealed to his tired eyes a stretch of mesa ahead, dotted with inviting clumps of bunch-grass. Then of his own volition he came to a stop and fell to grazing. Soon all the horses were standing with mouths to earth, feeding eagerly.

The men, sitting for a time in quiet conversation, finally dismounted, laughing now and then, and casting amused glances toward the black horse.

Soon they mounted again to take the trail. Instead of riding with the other on the sorrel, the odd man swung up on Pat’s back behind his master. But as Pat no longer suffered from hunger, he complacently accepted the return of the double load. Then all moved forward. Pat jogged out of the canyon, turning to the right on the desert, and moved rapidly north in the shadow of the hills. He held to his stride, and toward noon, rounding a giant ridge projecting into the desert from the hills, he saw ahead on his right, perhaps two miles distant across a basin, the mouth of another canyon. Evidently his master saw it also, and obviously it contained danger, for he jerked Pat down to a walk. Almost instantly he knew that the danger was real, for the man, sounding a sharp command to the others, brought him to a full stop. Then followed an excited discussion, and, when it ended, Pat, gripped in vague uneasiness, found himself urged forward at top speed. Yet in a dim way he knew what was wanted of him. He flung himself into a long stride and dashed across the wide basin, across the mouth of the canyon, into the shadow of the hills again. Breathless, he slackened his pace with thirty excited horses around him, mad swirling clouds of dust all about, and before him the oppressive stillness of the desert. They were safely past the danger zone.

He pressed on at a slow canter. Ahead the mesa revealed numerous sand-dunes, large and small, rising into the monotonous skyline. Plunging among them, he mounted some easily, others he skirted as easily, and once, to avoid an unusually large one, he dropped down into the bed of an arroyo, traveled along its dry course, and then clambered up on the desert. But it was wearying work, and, becoming ever more aware of his double load, he began to chafe with dissatisfaction. Yet he held to his gait, hopeful of better things–he was always hopeful of better things now–until he reached another dune, larger than any as yet encountered, when once more he broke out of his stride to circle its bottom. As he did so, of his own volition he checked himself. Dead ahead he saw horses scattered about, and beyond the horses, rising limply in the noon haze, a thin column of smoke. Also, he felt both his riders stiffen. Then on the midday hush rose the crack of firearms from the direction of the camp.

His master lifted a shrill voice. He felt a mighty pull at his head. He swung around like a flash. Then came the flaying of a rope and frantic urging of heels. He plunged among the surging horses, dancing and whirling excitedly, and out into the open beyond. He set his teeth grimly, and raced headlong to the south, galloping furiously, tearing blindly over the desert. He headed straight for the distant basin, straight for the mouth of the canyon, hurtling forward, struggling mightily under his double load. He did not know it, but he was speeding into a tragic crisis.

The others overtook him. They were carrying but single loads. But they did not pass him. He saw to that. He burst forward into even greater speed, clung to it grimly, forged into a position well in the lead. And he held this place–around him frenzied horses, frantic riders; behind him, to the distant rear, shot after shot echoing over the desert; before him the baking sands, shimmering heat-waves, sullen and silent. He raced on, swinging up over dunes, dropping into hollows, speeding across flats, mounting over dunes again, on and on toward the basin and the mouth of the canyon–and protection.

But again disaster.
