South-east of the hauteville falls in the now rugged ravine, Khashm el-Muttalí, "Snout of the high" (town). It leads to the apex of the coralline formations, scattered over with fragments of gypsum, here amorphous, there crystalline or talc-like, and all dazzling white as powdered sugar. Signs of tent foundations and of buildings appear in impossible places; and the heights bear two Burj or "watchtowers," one visible afar, and dominating from its mamelon the whole land. The return to the main valley descends by another narrow gorge further to the south-east, called Sha'b el-Darak, or "Strait of the Shield:" the tall, perpendicular, and overhanging walls, apparently threatening to fall, would act testudo to an Indian file of warriors. High up the right bank of this gut we saw a tree-trunk propped against a rock by way of a ladder for the treasure-seeker. The Sha'b-sole is flat, with occasional steps and overfalls of rock, polished like mirrors by the rain-torrents; the mouth shows remains of a masonry-dam some fourteen feet thick by twenty-one long; and immediately below it are the bases of buildings and watercourses. Walking down the left bank of the great Wady, and between these secondary gorges that drain the "Yellow Hill," we came upon a dwarf mound of dark earth and rubbish. This is the Siyághah ("mint and smiths' quarter"), a place always to be sought, as Ba'lbak and Palmyra taught me. Remains of tall furnaces, now level with the ground, were scattered about; and Mr. Clarke, long trained to find antiques, brought back the first coins picked up in ancient Midian. The total gathered, here and in other parts of Magháir Shu'ayb, was 258, of which some two hundred were carried home untouched; the rest, treated with chloritic and other acids, came out well. One was a silver oval which may or may not have been a token. Eleven were thick discs, differing from the normal type; unfortunately the legends are illegible. The rest, inform bits of green stuff, copper and bronze, were glued together by decay, and apparently eaten out of all semblance of money until the verdigris of ages is removed.
