To attempt to correctly estimate the extent of ground under cultivation would be too hazardous to be of any value, for the oasis varies so much in width from place to place, according as the irrigating canals are taken far afield or not, that nothing short of a careful survey could give a satisfactory result. Again, it is impossible to state with accuracy the southern limits of the oasis, for much of the land situated south of the junction of the Wad Ziz and the Wad Gheris is only capable of cultivation after exceedingly heavy rains, when natives of the Aït Atta tribe till the banks as far as the Dayet ed Daura. From the northern limit of the oasis of Tizimi to the junction of the rivers Ziz and Gheris may be safely estimated at from forty to fifty miles, the average width of this portion of the oasis being about ten miles. All this district of, say, 450 square miles, is under dense palm cultivation. By this, however, one must not understand the whole oasis, for I have purposely ignored all that lies south of the meeting of the two rivers, a district which depends greatly upon floods and the melting of the Atlas snows for its varied supply, and what might be true of one year might be a gross exaggeration or underrating for any other season. I have above enumerated the seven districts into which the oasis of Tafilet is divided. It now remains to make a few notes about each of these divisions. To take them in geographical order. (i.) _Tizimi_, or Aït Izimi, is a large district extending along the west bank of the Wad Tizimi, as the main channel of the Wad Ziz is called at this part of its course, from the name of the district it passes through. The inhabitants of Tizimi are Arabs, though the name is essentially a Berber one, leading one to think that the original Berbers must have been displaced by Arab tribes. The present inhabitants are the Tizimi branch of the Ahl Subah Arabs, though one or two _ksor_ belong to Shereefian families. Constant fighting is occurring in this part, owing to the proximity of the Berbers at Medaghra and Ertib. Tizimi contains a great number of palm-trees and several large _ksor_, the principal being Kasbat el Barania, Kasbat ben Ali, and Ksar bel Hassen. To the north-west of Tizimi, a mile or so across the desert, is the oasis of Mulai Brahim, where is the tomb of the saint so named, a place of pilgrimage. The oasis properly belongs to Tizimi, and is in the hands of the Shereefs and the Ahl Subah. I saw the tomb when passing through Tizimi. It is a large, domed, square building, painted white, and surrounded by a few smaller tombs of less important Shereefs. Separating Tizimi from the two nearest districts, Es Sifa on the south-west and Tanijiud on the south-east, is a strip of desert varying in extent from two to five miles, through which the Wad Ziz flows in a sandy bed, a few oleanders and coarse herbage being the only signs of vegetation on its banks.
