_The Tensift._[20]—This river rises in the Atlas, east of Marocco, and passing about five miles north of that city, it proceeds through the territory of Marocco, Rahamena, and nearly divides the two maritime provinces of Shedma and Abda, discharging itself into the ocean about sixteen miles south of the town of Saffy. This river receives in its course some tributary streams issuing from Atlas, the principal of which is the Wed Niffis, which, flowing from the south, enters it, after taking a northerly course through the plains of Marocco or Sheshawa. The Tensift is an impetuous stream during the Liali, but in summer it is fordable in several places; and at the ferry near the mouth of the river, at low water, reaches as high as the stirrups. In many places it is extremely deep, and dangerous to cross without a guide; about six miles from Marocco, a bridge crosses it, which was erected by Muley El Mansor; it is very strong but flat, with many arches. One of the Kings of Marocco attempted to destroy this bridge, to prevent the passage of an hostile army, but the cement was so hard that men with pick-axes were employed several days before they could sever the stones; and they had not time to effect its destruction, before the army passed. The shebbel of the Tensift is much esteemed, as is also the water, which is extremely salubrious, and aids considerably the powers of digestion, which, from the intense heat of the climate, are often weakened and relaxed. This river is supposed to be the _Phut_ of Ptolemy; on the northern bank, where it falls into the ocean, is to be perceived the ruins of an ancient town, probably the _Asama_ of that Geographer. There is a small stream two miles south of Mogodor, from whence that town is supplied with water; and about twelve or fourteen miles more to the south, we reach _The River Tidsi_, which discharges itself into the ocean a few miles south of Tegrewelt, or Cape Ossem, where the ancient city of Tidsi formerly stood. Passing to the south in the plains at the foot of that branch of Atlas which forms Afarnie, or the lofty Cape de Geer,[21] we meet _The River Benitamer_, which, with the before mentioned branch of Atlas, divides the provinces of Haha and Suse. Farther to the south is another river called _Wed Tamaract_; and about sixteen or seventeen miles south of that place, and about six south of Agadeer, or Santa Cruz,[22] the majestic
