The most striking object of this portion of the crust of the globe, is the vast Atlas chain of mountains [15], which traverses Morocco from north-east to south-west, whose present ascertained culminating point, Miltsin, is upwards of 15,000 feet above the level of the sea, or equal to the highest peaks of the Pyrenees. The Maroquine portion of the Atlas contains its highest peaks, which stretch from the east of Tripoli to the Atlantic Ocean, at Santa Cruz; and we find no mountains of equal height, except in the tenth degree of North latitude, or 18,000 miles south, or 30,000 south, south-east. The Rif coast has a mountainous chain of some considerable height, but the Atlantic coast offers chiefly ridges of hills. The coasts of Morocco are not much indented, and consequently have few ports, and these offer poor protection from the ocean. The general surface of Morocco presents a large ridge or lock, with two immense declivities, one sloping N.W. to the ocean, with various rivers and streams descending from this enormous back-bone of the Atlas, and the other fulling towards the Sahara, S.E., feeding the streams and affluents of Wad Draha, and other rivers, which are lost in the sands of the Desert. This shape of the country prevents the formation of those vast _Sebhahas_, or salt lakes, so frequent in Algeria and the south of Tunis. We are acquainted only with two lakes of fresh or sweet water--that of Debaia, traversed by Wad Draha,--and that of Gibel-Akhder, which Leo compares to Lake Bolsena. The height of the mountains, and the uniformity of their slopes, produce large and numerous rivers; indeed, the most considerable of all North Africa. These rivers of the North are shortest, but have the largest volume of water; those of the South are larger, but are nearly dry the greater part of the year. None of them are navigable far inland. Some abound with fish, particularly the Shebbel, or Barbary salmon. It is neither so rich nor so large as our salmon, and is whitefleshed; it tastes something like herring, but is of a finer and more delicate flavour. They are abundant in the market of Mogudor. The Shebbel, converted by the Spaniards Sabalo, is found in the Guadalquivir.
