The last of the yellow winds was eddying slowly past. All about him the air, thinning rapidly, pulsated in the sun's rays, which, beaming mildly down upon the desert, were spreading everywhere in glorious sheen. To the east, the mountains, stepping forth in the clearing atmosphere, lay revealed in a warmth of soft purple; while the slopes to the west, over which the storm had broken, shone in a wealth of dazzling yellow-white light--sunbeams scintillating off myriads of tiny sand-cubes. The desert was itself again--bright, resplendent-gripped in the clutch of solitude. Felipe tossed his blanket back upon the reach of the rigging. Then he caught up reins and whip, ready to go on. As he did so he paused in dismay. For one of the mares was down! It was the off mare, the slower and the older mare of the two. She was lying prone and she was breathing heavily. Covered as she was with a thin layer of fine sand, and tightly girdled with chaotic harness straps, she was a spectacle of abject misery. But Felipe did not see this. All he saw, in the blinding rage which suddenly possessed him, was a horse down, unready for duty, and beside her a horse standing, ready for duty, but restrained by the other. Stringing out a volley of oaths, he stepped to the side of the mare and jerked at her head, but she refused stubbornly to get up on her feet. Gripped in dismay deeper than at first, Felipe fell back in mechanical resignation. Was the mare dying? he asked himself. He could ill afford to lose a mare. Horses cost seven and eight dollars, and he did not possess so much money. Indeed, all the money he had in the world was three dollars, received for this last load of wood in town. So, what to do! Cursing the mare had not helped matters; nor could he accuse the storm, for there had been other storms, many of them, and each had she successfully weathered--been ready, with its passing, to go on! But not so this one! She--Huh? Could it be possible? Ah! He looked at the mare with new interest. And the longer he gazed the more his anger subsided, became finally downright compassion. For he was reviewing a something he had contemplated at odd times for weeks with many misgivings and tenacious unbeliefs. Never had he understood it! Never would he understand that thing! So why lose time in an effort to understand it now?
