The territory of SIWAH is of considerable extent;[5] its principal and most fruitful district is a well watered valley of about fifty miles in circuit, hemmed in by steep and barren rocks. Its soil is a sandy loam, in some places rather poached or fenny; but, assisted by no great industry of the natives, it produces corn, oil, and vegetables for the use of man or beast: its chief produce, however, consists in dates, which, from their great quantity and excellent flavour, render the place proverbial for fertility among the surrounding Arabs of the Desert. Each inhabitant possesses one or more gardens, making his relative wealth; and these it is his whole business to water and cultivate. A large garden yielding all such produce as is natural to the country, is valued at the price of from four to six hundred imperial dollars, there termed _real-patuacks_. The gardens round the towns or villages, are fenced with walls from four to six feet high, and sometimes with hedges; they are watered by many small streams of salt or sweet water, falling from the bordering rocks and mountains, or issuing from springs rising in the plain itself, and which, for the purposes of irrigation, being diverted into many small channels, expend themselves in the vale, and in no instance flow beyond the limits of this people’s territory. The dates produced are preserved in public magazines, of which the key is kept by the Sheik: to these storehouses the dates are brought in baskets closely rammed down, and a register of each deposit is kept. North-west of Siwah, there is a stratum of salt extending a full mile, and near it salt is found on the surface, lying in clods or small lumps. On this spot rise numerous springs, and frequently a spring of water perfectly sweet is found within a few paces from one which is salt. North of Siwah, on the road leading to _El-Mota_, I found many of these salt springs quite close to others which were sweet.
