The main range at this part forms in reality but one of four parallel chains. To the north of Marakesh the hills are known as Jibeelet, and extend from near the Atlantic beyond the eastern end of the tribe-land of Rahamna, terminating a few miles beyond Kalá. South of this some twenty miles, and parallel with it, is the principal range, beyond which, at an average distance of some twenty-five miles, is Jibel Saghru, or the Anti-Atlas. However, although the first two mentioned run directly east and west, Jibel Saghru forms a large district of broken chains of mountains, the valleys of which lead in every direction, for it empties such streams as flow in rainy seasons east into the Wad Gheris, west to the Draa, north to the Dads, and south to the desert. Yet in spite of this the system takes an easterly and westerly direction, the same being more apparent after the spot where the Wad Draa divides the range into two portions. The natives call only the eastern portion Saghru, not connecting it with the hills to the west of the Draa, which form eventually the southern side of the Wad Sus. There is yet another line of hills still farther to the south, Jibel Bani, which rise near the Draa south of the _zauia_ of Tamgrut and continue to the west. It has always been a question as to where they terminate; but I was pointed out at Tafilet, from above the hill at Dar el baida, the end of a chain of mountains to the south, which sink gradually to the valley of the now united course of the Wad Gheris and Wad Ziz. Beyond there appeared to be nothing but desert sand, and this, I was informed, was the western extremity of Jibel Bani. It is difficult to hazard an opinion as to where the highest peak of the Moroccan Atlas will be found to exist, for at present but very few observations of the high altitudes have been taken, though both Sir Joseph Hooker and Mr Joseph Thomson reached to about 12,000 feet. In the native opinion Jibel Ayashi, in which most of the large rivers of Morocco rise, surpasses the other peaks in altitude; but, as far as I know, no European has ever seen it, much less been there. Some geographers are of the opinion that the highest point will be found amongst the mountains almost due south of Morocco City. So equal are the summits in this direction that it will take many ascents before any definite result can be arrived at, though, with the exception of the obstruction of the native officials, no great difficulties ought to arise, as the snow in summer and early autumn almost altogether disappears, and no glaciers are found throughout the whole range; nor do the mountain-tops rise in precipitous peaks, but, as a rule, are flat and undulating.
