brain sleeps while the rest is wide awake. At last, about 2 30 A.M., thoroughly "knocked up"—a phrase which I should advise the Englishman to eschew in the society of the fair Columbian—we sighted a roofless shed, found a haystack, and, reckless of supper or of stamping horses, fell asleep upon the sand.
Sand-Springs Station deserved its name. Like the Brazas de San Diego and other mauvaises terres near the Rio Grande, the land is cumbered here and there with drifted ridges of the finest sand, sometimes 200 feet high, and shifting before every gale. Behind the house stood a mound shaped like the contents of an hour-glass, drifted up by the stormy S.E. gale in esplanade shape, and falling steep to northward or against the wind. The water near this vile hole was thick and stale with sulphury salts: it blistered even the hands. The station-house was no unfit object in such a scene, roofless and chairless, filthy and squalid, with a smoky fire in one corner, and a table in the centre of an impure floor, the walls open to every wind, and the interior full of dust. Hibernia herself never produced aught more characteristic. Of the employés, all loitered and sauntered about desœuvrés as cretins, except one, who lay on the ground crippled and apparently dying by the fall of a horse upon his breast-bone.
About 11 A.M. we set off to cross the ten miles of valley that stretched between us and the summit of the western divide still separating us from Carson Lake. The land was a smooth saleratus plain, with curious masses of porous red and black basalt protruding from a ghastly white. The water-shed was apparently to the north, the benches were distinctly marked, and the bottom looked as if it were inundated every year. It was smooth except where broken up by tracks, but all off the road was dangerous ground: in one place the horses sank to their hocks, and were not extricated without difficulty. After a hot drive—the glass at 9 A.M. showed 74° F.—we began to toil up the divide, a sand formation mixed with bits of granite, red seeds, and dwarf shells, whose lips were for the most part broken off. Over the fine loose surface was a floating haze of the smaller particles, like the film that veils the Arabian desert. Arrived at the summit, we sighted for the first time Carson Lake, or rather the sink of the Carson River. It derives its name from the well-known mountaineer whose adventurous roamings long anticipated scientific exploration. Supplied by the stream from the eastern flank of the Sierra Nevada, it is just such a lake as might be formed in any of the basins which we had traversed—a shallow sheet of water, which, in the cloudy sky and mitigated glare of the sun, looked pale and muddy. Apparently it was divided by a long, narrow ruddy line, like ochre-colored sand; a near approach showed that water on the right was separated from a saleratus bed on the left by a
