The regular cone of El-Maklá' ends the prospect in the north-eastern direction. Looking westward, we see the ghastly bare and naked Secondary formation, the Rughám of the Bedawin, not to be confounded with Rukhám ("alabaster or saccharine marble"). We afterwards traced this main feature of the 'Akabah Gulf as far south as the Wady Hamz. It is composed of the sulphates of lime--alabaster, gypsum, and the plaster with which the Tertiary basin of Paris supplies the world; and of the carbonates of lime--marble, chalk, kalkspar, shells, and eggs. The broken crests of the Jibál el-Hamrá, the red hills backing Makná,[EN#33] and the jagged black peaks of their eastern parallel, the Kalb el-Nakhlah, look like plutonic reefs or island-chains emerging from the Secondary sea. The latter, whose bleached and skeleton white is stained, here and there, by greenish-yellow sands, chlorite and serpentine, stands boldly out from the chaos of purpling mountains composing Sinai, and ending southwards in the azure knobs of three-headed Tirán Island. The country, in fact, altogether changed: quartz had disappeared, and chlorite had taken its place. We passed the night at El-'Usaylah, a Ghadir (or "hollow") without drainage, which the sinking of water cakes with mud and covers with an irregular circle of salsolaceous trees, a patch of dark metallic green. This "'Usaylah" is eaten by camels, but rejected by mules. Here our post reached us from Suez on the seventh day, having started on the 2nd inst. A dollar was offered to the Bedawi, who eyed the coin indignantly, declaring that it ought to be a ginni (guinea). I had also given him some tobacco, and repented, as usual, my generosity. Next day we finished the last and larger part of the second pilgrim-stage from El-Muwaylah. Our Arabs had been "dodging;" and, much disappointed about converting a two days' into a three days' march, they punished us by feeding their camels on the road, and by not joining us till the evening. As before, there was no game till we approached the springs; yet tufts and scatters of tamarisks, Samur (Inga unguis) and Arák (Salvadora), looked capable of sheltering it. And now, beyond the level and monotonous Desert, we began to see our destination;--palms and tufty trees at the mouth of a masked Wady. This watercourse runs between a background of reddish-brown rock, the foot-hills and sub-ranges of the grand block, "El-Zánah," to the north; and a foreground of pale-yellow, stark-naked gypsum, apparently tongue-shaped. Above the latter tower two sister-quoins of ruddy material, the Shigdawayn, to which a tale hangs.
