As he descended into the valley, keeping close to Wolf, he marked a straight course in line with a volcanic spur. He was surprised when the dog, though continually threading jumbles of rock, heading canyons, crossing deep washes, and going round obstructions, always veered back to this bearing as true as a compass-needle to its magnet.
Hare felt the air growing warmer and closer as he continued the descent. By mid-afternoon, when he had travelled perhaps thirty miles, he was moist from head to foot, and Silvermane's coat was wet. Looking backward Hare had a blank feeling of loss; the sweeping line of Echo Cliffs had retreated behind the horizon. There was no familiar landmark left.
Sunset brought him to a standstill, as much from its sudden glorious gathering of brilliant crimsons splashed with gold, as from its warning that the day was done. Hare made his camp beside a stone which would serve as a wind-break. He laid his saddle for a pillow and his blanket for a bed. He gave Silvermane a nose-bag full of water and then one of grain; he fed the dog, and afterward attended to his own needs. When his task was done the desert brightness had faded to gray; the warm air had blown away on a cool breeze, and night approached. He scooped out a little hollow in the sand for his hips, took a last look at Silvermane haltered to the rock, and calling Wolf to his side stretched himself to rest. He was used to lying on the ground, under the open sky, out where the wind blew and the sand seeped in, yet all these were different on this night. He was in the Painted Desert; Wolf crept close to him; Mescal lay somewhere under the blue-white stars.
He awakened and arose before any color of dawn hinted of the day. While he fed his four-footed companions the sky warmed and lightened. A tinge of rose gathered in the east. The air was cool and transparent. He tried to cheer Wolf out of his sad-eyed forlornness, and failed.
Hare vaulted into the saddle. The day had its possibilities, and while he had sobered down from his first unthinking exuberance, there was still a ring in his voice as he called to the dog:
"On, Wolf, on, old boy!"
Out of the east burst the sun, and the gray curtain was lifted by shafts of pink and white and gold, flashing westward long trails of color.
When they started the actions of the dog showed Hare that Wolf was not tracking a back-trail, but travelling by instinct. There were draws which necessitated a search for a crossing, and areas of broken rock which had to be rounded, and steep flat mesas rising in the path, and strips of deep sand and canyons impassable for long distances. But the dog always found a way and always came back to a line with the black spur that Hare had marked. It still stood in sharp relief, no nearer than before, receding with every step, an illusive landmark, which Hare began to distrust.
Then quite suddenly it vanished in the ragged blue mass of the Ghost Mountains. Hare had seen them several times, though never so distinctly. The purple tips, the bold rock-ribs, the shadowed canyons, so sharp and clear in the morning light–how impossible to believe that these were only the deceit of the desert mirage! Yet so they were; even for the Navajos they were spirit-mountains.
The splintered desert-floor merged into an area of sand. Wolf slowed his trot, and Silvermane's hoofs sunk deep. Dismounting Hare labored beside him, and felt the heat steal through his boots and burn the soles of his feet. Hare plodded onward, stopping once to tie another moccasin on Wolf's worn paw, this time the left one; and often he pulled the stopper from the water-bag and cooled his parching lips and throat. The waves of the sand-dunes were as the waves of the ocean. He did not look backward, dreading to see what little progress he had made. Ahead were miles on miles of graceful heaps, swelling mounds, crested ridges, all different, yet regular and rhythmical, drift on drift, dune on dune, in endless waves. Wisps of sand were whipped from their summits in white ribbons and wreaths, and pale clouds of sand shrouded little hollows. The morning breeze, rising out of the west, approached in a rippling lines like the crest of an inflowing tide.
Silvermane snorted, lifted his ears and looked westward toward a yellow pall which swooped up from the desert.
"Sand-storm," said Hare, and calling Wolf he made for the nearest rock that was large enough to shelter them. The whirling sand-cloud mushroomed into an enormous desert covering, engulfing the dunes, obscuring the light. The sunlight failed; the day turned to gloom. Then an eddying fog of sand and dust enveloped Hare.,. His last glimpse before he covered his face with a silk handkerchief was of sheets of sand streaming past his shelter. The storm came with a low, soft, hissing roar, like the sound in a sea-shell magnified. Breathing through the handkerchief Hare avoided inhaling the sand which beat against his face, but the finer dust particles filtered through and stifled him. At first he felt that he would suffocate, and he coughed and gasped; but presently, when the thicker sand-clouds had passed, he managed to get air enough to breathe. Then he waited patiently while the steady seeping rustle swept by, and the band of his hat sagged heavier, and the load on his shoulders had to be continually shaken off, and the weighty trap round his feet crept upward. When the light, fine touch ceased he removed the covering from his face to see himself standing nearly to his knees in sand, and Silvermane's back and the saddle burdened with it. The storm was moving eastward, a dull red now with the sun faintly showing through it like a ball of fire.
"Well, Wolf, old boy, how many storms like that will we have to weather?" asked Hare, in a cheery tone which he had to force. He knew these sand-storms were but vagaries of the desert-wind. Before the hour closed he had to seek the cover of a stone and wait for another to pass. Then he was caught in the open, with not a shelter in sight. He was compelled to turn his back to a third storm, the worst of all, and to bear as best he could the heavy impact of the first blow, and the succeeding rush and flow of sand. After that his head drooped and he wearily trudged beside Silvermane, dreading the interminable distance he must cover before once more gaining hard ground. But he discovered that it was useless to try to judge distance on the desert. What had appeared miles at his last look turned out to be only rods.
It was good to get into the saddle again and face clear air. Far away the black spur again loomed up, now surrounded by groups of mesas with sage-slopes tinged with green. That surely meant the end of this long trail; the faint spots of green lent suggestion of a desert waterhole; there Mescal must be, hidden in some shady canyon. Hare built his hopes anew.
So he pressed on down a plain of bare rock dotted by huge bowlders; and out upon a level floor of scant sage and greasewood where a few living creatures, a desert-hawk sailing low, lizards darting into holes, and a swiftly running ground-bird, emphasized the lack of life in the waste. He entered a zone of clay-dunes of violet and heliotrope hues; and then a belt of lava and cactus. Reddish points studded the desert, and here and there were meagre patches of white grass. Far away myriads of cactus plants showed like a troop of distorted horsemen. As he went on the grass failed, and streams of jagged lava- flowed downward. Beds of cinders told of the fury of a volcanic fire. Soon Hare had to dismount to make moccasins for Wolf's hind feet; and to lead Silvermane carefully over the cracked lava. For a while there were strips of ground bare of lava and harboring only an occasional bunch of cactus, but soon every foot free of the reddish iron bore a projecting mass of fierce spikes and thorns. The huge barrel-shaped cacti, and thickets of slender dark-green rods with bayonet points, and broad leaves with yellow spines, drove Hare and his sore-footed fellow-travellers to the lava.
