PHYSICAL FEATURES
Watercourses in ‘Ajliin
W. Rdjib, rising about 3 m. due west of Suf, near the culmi
nating point of the country, is separated from N. ez-Zerqa
by the southern part of the main watershed, the course of
which it follows on the northern side, descending first almost
S., then turning WSW., to flow down to Jordan. It carries
water almost from its head, and is the most copious stream
between Zerqa and Yarmuk, though much diversion for pur
poses of irrigation reduces the volume in its lower reaches.
It is known successively as W. el-Khadhr, W. Hammur, W.
‘Arabian, and W. Rajib, and like all the western ‘Ajlun water
courses runs mostly in a deep narrow valley, partially wooded,
and rich in waterside growths ; it is most open, and has most
cultivable ground, near the village of Rajib. On the 1.
(southern) bank, where the watershed is generally near, its
affluents are short and of no importance, the only tributary
of any length on this side being W. es-Suq (W. Sham), which
comes in from the E., rising south of Sakib ; it has no perennial
brook. Along its lower course the water-parting dividing
it from W. Kefrinji to N. abuts close upon the bed, but recedes
above the village of Rajib, and leaves space for an affluent
with extensive branches, rising near the head of the main
stream and S. of El-Bediyeh : the lowest branch on the 1. bank,
W. Sarabis, alone carries a permanent stream, having springs
in its valley. An irrigation-channel more than a mile long
runs along the north bank from Rajib westwards.
W. Kefrinji is important as having on its banks the three
large villages of Kefrinji, ‘Ajlun, and ‘Ain Janna its upper
middle valley forming the heart of higher ‘Ajlun, a beautiful
and healthy region, still finely wooded. Rising on the main
watershed west of Suf close to the north of W. Rajib, and flowing
in a general SW. direction, it has apparently fewer local names
than other watercourses of its length, and is generally known
as W. Kefrinji or W. ‘Ajlun. It begins to carry water about
4 m. from its head, just above the village of ‘Ain Janna, and
is swollen at ‘Ajlun by a brook from its northern tributary,
