THE HOARY DESERT. 175 countless columned edifices of marble whiteness, and studded with domes, spires, and turreted towers, would rise upon the horizon of the plain, astonishing us with its stupendous grandeur and sublime magnificence. But it is in vain to attempt a description of these singular and extraordinary phenomena. Neither prose or poetry, nor the pencil of the artist, can adequately portray their beauties. The whole distant view around, at this point, seemed like the creations of a sublime and gorgeous dream, or the effect of enchantment. I observed that where these appearances wrere presented in their most varied forms, and with the most vivid distinctness, the surface of the plain was broken, either by chasms hollowed out from the action of the winds, or by undulations formed of the drifting sands. About eleven o'clock we struck a vast white plain, uniformly level, and utterly destitute of vegetation or any sign that shrub or plant had ever existed above its snow-like surface. Pausing a few moments to rest our mules, and moisten our mouths and throats from the scant supply of beverage in our powder-keg, we entered upon this appalling field of sullen and hoary desolation. It was a scene so entirely new to us, so frightfully forbidding and unearthly in its aspects, that all of us, I believe, though impressed with its sublimity, felt a slight shudder of apprehension. Our mules seemed to sympathize with us in the pervading sentiment, and moved forward with reluctance, several of them stubbornly setting their faces for a countermarch. For fifteen miles the surface of this plain is so compact, that the feet of our animals, as we hurried them along over it, left but little if any impression for the guidance of the future traveller. It is covered with a hard crust of saline and alkaline substances combined, from one-fourth to one-half of an inch in thickness, beneath which is a stratum of damp whitish sand and clay intermingled. Small fragments of white shelly rock, of an inch and a half in thickness, which appear as if they once composed a crust, but had been broken by the action of the atmosphere or the pressure of water rising from beneath, are strewn over the entire plain and imbedded in the salt and sand. As we moved onward, a member of our party in the rear
