The mustang could not share his rider’s source of content, but he may have been conscious, through animal instincts whereof we know nothing, of an uplifting and encouraging spirit. At all events, he kept up his steady lope without faltering or apparent effort, and seemed to require nothing more than the occasional wetting which Freeman administered to his nose. There would probably be some vegetation, and perhaps water, on the hills; and that prospect may likewise have helped him along.

Nevertheless, man and beast may well have welcomed the hour when the craggy acclivities of that lonely range became so near that they seemed to loom above their heads. Freeman directed his steps towards the southern extremity, where a huge, pallid mass, of almost regular pyramidal form, reared itself aloft like a monument. He skirted the base of the pyramid, and there opened on his view a narrow, winding valley, scarcely half a mile in apparent breadth, and of a very wild and savage aspect. Its general direction was nearly north and south, and it declined downwards, as if seeking the interior of the earth. In fact, it looked not unlike those imaginative pictures of the road to the infernal regions described by the ancient poets. One could picture Pluto in his chariot, with Proserpine beside him, thundering downwards behind his black horses, on the way to those sombre and magnificent regions which are hollowed out beneath the surface of the planet.

Freeman, however, presently saw a sight which, if less spectacularly impressive, was far more agreeable to his eyes. On a shelf or cup of the declivity was a little clump of vegetation, and in the midst of it welled up a thin stream of water. The mustang scrambled eagerly towards it, and, before Freeman had had time to throw himself out of the saddle, he had plunged his muzzle into the rivulet. He sucked it down with such satisfaction that it was evident the water was not salt. Freeman laid himself prone upon the brink, and followed his steed’s example. The draught was cool and pure.

“I didn’t know how much I wanted it!” said he to himself. “It must come from a good way down. If I could only bring the parent stream to the surface, my mission would be on a fair road to success.”

An examination of the spring revealed the fact that it could not have been long in existence. Indeed, there were no traces whatever of long continuance. The aperture in the rock through which it trickled bore the appearance of having been recently opened; fragments were lying near it that seemed to have been just broken off. The bed of the little stream was entirely free from moss or weeds; and after proceeding a short distance it dwindled and disappeared, either sucked up in vapor by the torrid air, or absorbed into the dusty soil. Manifestly, it was a recent creation.

“And, to be sure, why not?” ejaculated Freeman. “There was an earthquake last night, which swallowed up the spring in the Trednokes’ garden: probably that same earthquake brought this stream to light. It vanished there, to reappear here. Well, the loss is not important to them, but the gain is very important to me. It is as if Miriam had come with a cup of water to refresh her lover in the desert. God bless her! She has refreshed me indeed, soul and body!”

He removed the saddle from the mustang, and turned him loose to make the best of such scanty herbage as he could find. Then he unpacked his own provisions, and made a comfortable meal; after which he rolled a cigarette and reclined on the spot most available, to rest and recuperate. The valley, or gorge, lay before him in the afternoon light. It was a strange and savage spectacle. Had it been torn asunder by some stupendous explosion, it could not have presented a rougher or more chaotic aspect. To look at it was like beholding the secret places of the earth. The rocky walls were of different colors, yellow, blue, and red, in many shades and gradations. They towered ruggedly upwards, sharply shadowed and brightly lighted, mounting in regular pinnacles, parting in black crevices; here and there vast masses hung poised on bases seemingly insufficient, ready to topple over on the unwary passer beneath. A short distance to the northward the ravine had a turn, and a projecting promontory hid its further extreme from sight. Freeman made up his mind to follow it up on foot, after the descending sun should have thrown a shadow over it. The indications, in his judgment, were not without promise that a system of judiciously-applied blastings might open up a source of water that would transform this dreadful barrenness into something quite different.

The shade of the great pyramid fell upon him as he lay, but the tumultuous wall opposite was brilliantly illuminated: the sky, over it, was of a peculiar brassy hue, but entirely cloudless. The radiations from the baked surface, ascending vertically, made the rocky bastion seem to quiver, as if it were a reflection cast on undulating water. The wreaths of tobacco-smoke that emanated from Freeman’s mouth also ascended, until they touched the slant of sunlight overhead. As the young man’s eyes followed these, something happened that caused him to utter an exclamation and raise himself on one arm.

All at once, in the vacant air diagonally above him, a sort of shadowy shimmer seemed to concentrate itself, which was rapidly resolved into color and form. It was much as if some unseen artist had swept a mass of mingled hues on a canvas and then had worked them with magical speed into a picture. There appeared a breadth of rolling country, covered with verdure, and in the midst of it the white walls and long, shadowed veranda of an adobe house. Freeman saw the vines clambering over the eaves and roof, the vases of earthenware suspended between the pillars and overflowing with flowers, the long windows, the steps descending into the garden. Now a figure clad in white emerged from the door and advanced slowly to the end of the veranda. He recognized the gait and bearing: he could almost fancy he discerned the beloved features. She stood there for a moment, gazing, as it seemed, directly at him. She raised her hands, and pressed them to her lips, then threw them outwards, with a gesture eloquent of innocent and tender passion. Freeman’s heart leaped: involuntarily he stretched out his arms, and murmured, “Miriam!” The next moment, a tall, dark figure, with white hair, wrapped in a blanket, came stalking behind her, and made a beckoning movement. Miriam did not turn, but her bearing changed; her hands fell to her sides; she seemed bewildered. Freeman sprang angrily to his feet: the picture became blurred; it flowed into streaks of vague color; it was gone. There were only the brassy sky, and the painted crags quivering in the heat.

“That was not a mirage: it was a miracle,” muttered the young man to himself. “Forty miles at least, and it seemed scarcely three hundred yards! What does it mean?”
