Two of them approach each other. There is a short, ghastly struggle that ends in their mutual destruction. The sand is precipitated to the earth, and the dust floats off in dun, shapeless masses. Several have shut me within a space, and are slowly closing upon me. My dog howls and barks. The horse cowers with affright, and shivers between my thighs, uttering terrified expressions. My brain reels. Strange objects appear. The fever is upon me! The laden currents clash in their wild torsion. I am twisted around and torn from my saddle. My eyes, mouth, and ears are filled with dust. Sand, stones, and branches strike me spitefully in the face; and I am flung with violence to the earth! I lay for a moment where I had fallen, half-buried and blind. I was neither stunned nor hurt; and I began to grope around me, for as yet I could see nothing. My eyes were full of sand, and pained me exceedingly. Throwing out my arms, I felt for my horse; I called him by name. A low whimper answered me. I staggered towards the spot, and laid my hands upon him; he was down upon his flank. I seized the bridle, and he sprang up; but I could feel that he was shivering like an aspen. I stood by his head for nearly half an hour, rubbing the dust from my eyes; and waiting until the simoom might settle away. At length the atmosphere grew clearer, and I could see the sky; but the sand still drifted along the ridges, and I could not distinguish the surface of the plain. There were no signs of Gode. I mounted and commenced riding over the plain in search of my comrade. I had no idea of what direction he had taken. I made a circuit of a mile or so, still calling his name as I went. I received no reply, and could see no traces upon the ground. I rode for an hour, galloping from ridge to ridge, but still without meeting any signs of my comrade or the mules. I pulled up in despair. I had shouted until I was faint and hoarse. I could search no longer. I was thirsty, and would drink. O God! my "xuages" are broken! The pack-mule has carried off the water-skin. The crushed calabash still hung upon its thong; but the last drops it had contained were trickling down the flanks of my horse. I knew that I might be fifty miles from water! You cannot understand the fearfulness of this situation. You live in a northern zone, in a land of pools and streams and limpid springs. How unlike the denizen of the desert, the voyageur of the prairie sea! Water is his chief care, his ever-present solicitude; water the divinity he worships. Without water, even in the midst of plenty, plenty of food, he must die. In the wild western desert it is the thirst that kills. No wonder I was filled with despair. I believed myself to be about the middle of the Jornada. I knew that I could never reach the other side without water. The yearning had already begun. My throat and tongue felt shrivelled and parched.
