When the heat of the sun began to decline, I took a walk through the valley; and being attracted by a circle laid out very regularly with large slabs like the opening of a well, I began to ascend the steep cliffs opposite the mouth of the valley of Áman sémmedné, rising to a height of about 500 feet, and which, as I clearly saw, had been repeatedly ascended. The cliffs are here, as is usual in this formation, broken into regular strata; and steep flat blocks standing upright give them an imposing appearance. My search here, however, led only to the discovery of the well-chiselled form of a single bullock, in exactly the same style as that in Wadi Telísaghé, though it had suffered a little from its exposed situation; but the whole appearance of the locality shows that in former times it contained more of this kind. On the plain above the cliffs is another circle regularly laid out, and, like the many circles seen in Cyrenaica and in other parts of Northern Africa, evidently connected with the religious rites of the ancient inhabitants of these regions. Quartz pebbles were scattered about this part of the valley. Our people meanwhile had been busy laying in provision of dry herbage for the next marches, during which we were told our camels would scarcely find anything to feed upon; and our Tawárek friends, when they at length arrived for their supper, did the same. [Sidenote: Monday, July 8th.] The caravan of the Tawáti having passed by our encampment at an early hour, we followed betimes, having an interesting day’s march before us. For the first three miles we still kept along the large valley, into which masses of sand had been driven down from the plateau by the strong east winds: further on it became dry and bare. To this succeeded an irregular knot of hollows and plains between the sides of the plateau, which in some places formed imposing promontories and detached buttresses, all on one and the same level. We then began to ascend along a sort of broad valley, which gradually assumed a regular shape, and bore the name of Tísi. The slope of the plateau was shaped into regular strata, the uppermost of which form steep precipices like the walls of a castle; the lower ones slope down more gradually. Here we discovered ahead of us, at the foot of the southern slope, the encampment of the pilgrim-caravan, who were resting during the heat of the day. We continued our march, always ascending, till a little after noon we reached the edge of the pass, a perfect watershed, of more than 2000 feet elevation, descending more gradually towards the east as far as the well of Sháraba, while towards the west it formed a steep precipice, passable only along a most interesting gully cut into it by the water towards the Valley of Ghát. The higher level, which rises above the pass about 300 feet, seems to be considerably depressed in this place, where it collects large floods of water, such as could alone cut the
