and et Tuwanik (alt. 2,847 feet), then near Tana to the northern extremity of the basin near Sheikh Kamil (alt. 1,923 feet). The length is about twelve miles.
The hypotenuse of this triangular basin faces the north- east and is coterminous with the Wady Far'ah, in connection with which it has been already traced. Its length is about thirteen miles.
The Watercourses of Wady el Humr Basin.
Two main streams receive the channels of this basin, and unite about a mile from the Jordan. These are the Wady el Humr which drains the northern part of the basin, and the Wady Fusail which is the outfall of the southern part. There is an intermediate channel which rises about two miles from the edge of the plain, and passes straight across it to the con- fluence, a further distance of five miles.
The sources of Wady el Humr extend along the western waterparting for about eight miles, between Sheikh Kamil and Mejdel Beni Fadl, and they form two divisions. The first rises at Tana and runs with the Koman road as Wady el Kerad into the Sahel or Plain of Ifjim. It receives a branch from Sheikh Kamil at a point midway between Tana and the plain ; and another branch comes from the same range of hills through Lahf Salim, and joins the Kerad at the upper end of the plain of Ifjim. At the lower end of the plain the Wady Zaniur joins the Kerad. The Zamur has the name of Wady ed Dowa above its entrance into the plain, and is the recipient of a series of tributaries which severally rise at Kh. Yanun, el Jeddua, Yanun, Akrabeh, and north of Mejdel Beni Fadl. These drain an upland tract, enclosed between the western waterparting and spurs which proceed from it and are drawn together at the gorge of Wady ed Dowa, the streams having united at the entrance of the gorge. After the junction of the Zamur the wady takes the name of Wady el Ifjim and receives short branches from the north-east parting at Bir
