The afternoon is hot and with scarcely a breath of air moving; the little valley terminates in a region of barren, red hills, on which the sun glares fiercely; some toughish climbing has to be accomplished in scaling a ridge, and then.  I emerge into an upland lava plateau, where the only vegetation is sun-dried weeds and thistles.  Here a herd of camels are contentedly browsing, munching the dry, thorny herbage with a satisfaction that is evident a mile away.  From casual observations along the route, I am inclined to think a camel not far behind a goat in the depravity of its appetite; a camel will wander uneasily about over a greensward of moist, succulent grass, scanning his surroundings in search of giant thistles, frost-bitten tumble-weeds, tough, spriggy camel thorns, and odds and ends of unpalatable vegetation generally.  Of course, the “ship of the desert” never sinks to such total depravity as to hanker after old gum overshoes and circus posters, but if permitted to forage around human habitations for a few generations, I think they would eventually degenerate to the goat’s disreputable level.  The expression of utter astonishment that overspreads the angular countenance of the camels browsing near the roadside, at my appearance, is one of the most ludicrous sights imaginable; they seem quite intelligent enough to recognize in a wheelman and his steed something inexplicable and foreign to their country, and their look of timid inquiry seems ridiculously unsuited to their size and the general ungainliness of their appearance, producing a comical effect that is worth going miles to see.  It is approaching sun-down, when, ascending a ridge overlooking another valley, I am gratified at seeing it occupied by several Koordish camps, their clusters of black tents being a conspicuous feature of the landscape.  With a fair prospect of hospitable quarters for the night before me, and there being no distinguishable signs of a road, I make my way across country toward one of the camps that seems to be nearest my proper course.  I have arrived within a mile of my objective point, when I observe, at the base of a mountain about half the distance to my right, a large, white two-storied building, the most pretentious structure, by long odds, that has been seen since leaving Angora.  My curiosity is, of course, aroused concerning its probable character; it looks like a bit of civilization that has in some unaccountable manner found its way to a region where no other human habitations are visible, save the tents of wild tribesmen, and I at once shape my course toward it.  It turns out to be a rock-salt mine or quarry, that supplies the whole region for scores of miles around with salt, rock-salt being the only kind obtainable in the country; it was from this mine that the donkey party from whom I first obtained bread this morning fetched their loads.  Here I am invited to remain over night, am provided with a substantial supper, the menu including boiled mutton,
