ten miles of country, while the lower course is constricted
into a single narrow valley. The most important upper
branch, extending farthest SE., is successively known by the
following local names : W. Rashdan, En-Nasab, ‘As‘as,
Damak, and Seneisil, below which the main valley is W.
Hammam and, finally, Siqlab. A northern branch, running
almost parallel and joining at W. Hammam, is first W. el-
Hamra, then W. Abu Shawal, and W. Tibneh, the important
village of that name lying between it and W. Damak to the
south. W. Sharut (El-Mezar) and ‘Ainbeh (El-‘Ahseini) are
eastern, and W. Hallan ed-Dlk, El-‘Ayun (Izmal, Fadl), and
‘Amiid north-eastern tributaries of W. Tibneh. W. Siqlab
has a continuous stream of perennial water only in the last
six miles or so of its course ; but there is a brook about a mile
in length flowing from ‘Ayun el-Hammam just below the con
fluence of W. Seneisil and Tibneh, and reinforced half-way by
other springs, ‘Ayun el-Jurn.
As in the case of W. el-Yabis, the region S. of the lower
course of W. Siqlab drains independently to the Jordan
Valley. The more important wadis of this slope are El-Jisr
(Sartabeh), rising NE. of Kefr Abil, Jirm el-Moz (Et-Tineh), on
which is Fahl, Seil el-Hammeh, with hot springs, and W. Abu
Zeyyad (El-Makhruqeh), all perennial in their lower courses.
W. et-Tayyibeh rises a little further N. on the main water
shed than W. Siqlab. It is peculiar in having no tributaries
of any length, its valley being closely confined on either side
by those of other systems from its head to its outlet into the
Jordan valley, on the S. by W. Siqlab, on the N. by W. el-
Hasa (Qusseib, En-Nuheir, El-Bir), draining directly to Jordan,
and by W. Shdmar, a tributary of W. el-‘Arab. W. et-
Tayyibeh has the following local names from E. to W. :
Hiyar, Habaqeh, Jurun, Seheil, Semmu‘, Tayyibeh. Near
the village of Semmu‘, on the S. side of its middle course,
the wadi bed is 500 ft. below the surrounding plateau ;
the village of Tayyibeh is also high on the plateau above
the N. bank a little farther to W. Though the wadi is
torrential in winter, at other seasons it has perennial water
