On the next day (February 22nd) we left the "Nagwah" at seven instead of six a.m., and passed to the right a granitic outcrop in the Wady bed, a reduced edition of the Burj. After an hour's slow walking we were led by a Bedawi lad, Hasan bin Husayn, to a rock-spur projected northwards from the left side and separating two adjacent Sayls or "torrent-beds," mere bays in the bank of mountains. A cut road runs to the top of the granite tongue, which faces the westernmost or down-stream outbreaks of the huge porphyritic masses on the other side of the Wady Sadr. The ridge itself is strewed with spalled stone, quartz broken from the veins that seam the granite, and with slag as usual admirably worked. Not a trace of human habitation appears, nor is there any tradition of a settlement having existed here; consequently we concluded that this was another atelier of wandering workmen. Below the rock-tongue we found for the first time oxydulated iron and copper, either free or engaged in trap and basaltic dykes: the former metal, also attached in layers to dark-red vermeilled jasper, here appears streaked with white quartz. Resuming our ride, we dismounted, after four miles, at the half-way Mahattah ("halting-place"): it is a rond-point in the Wady Sadr, marked from afar by a tall blue pyramid, the Jebel el-Ga'lah (Jálah). We spent some time examining this interesting bulge. Here the Jibál el-Tihámah end, and the eastern parallel range, the Jibál el-Shafah, begins. The former belong to the Huwaytát and to Egypt; the latter, partly to the Ma'ázah and to Syria. The geographical frontier is well marked by two large watercourses disposed upon a meridian, and both feeding the main drain, the Sadr-Tiryam. To the north the Wady Sawádah divides the granitic Harb from the porphyritic Jebel Sawádah; while the southern Wady Aylán separates the Dibbagh from the Jebel Aylán, a tall form distinctly visible from the Upper Shárr. The rest of our eastward march will now be through the Shafah massif. It resembles on a lower scale the Tihámah Gháts; but it wholly wants their variety, their beauty, and their grandeur. The granites which before pierced the porphyritic traps in all directions, now appear only at intervals; and this, I am told, is the case throughout the northern, as we found it to be in the southern, prolongation of the "Lip"-range. At the same time there is no distinct geographical separation between the two parallels; and both appear, not as if parted by neutral ground, but rather as topographical continuations of each other.
