eastwards from west-north-west of Risut, is the wadi A seasonal or intermittent watercourse, or the valley in which it flows. system ’of the
Nagar Ghaiz. None of these streams is actually perennial, judged
on a visible flow of water, but there seems to be a subterranean flow
seawards in some cases.
13. The only explorer who appears to have travelled in the
region north of the watershed, previous to my tour, was Mr. Bertram
Thomas. He recognizes the following wadis westwards from about
longitude 54° 30' E.: wadi A seasonal or intermittent watercourse, or the valley in which it flows. Dhahibun from near Dhikur, with two
tributaries—the Ingudan and the Ghazal; next the wadi A seasonal or intermittent watercourse, or the valley in which it flows. from
Hanun known as the Rakibit; then the wadi A seasonal or intermittent watercourse, or the valley in which it flows. through Mughagha
water-hole called the Dauka with its two west tributaries the Istu
and the Hauf; then comes the wadi A seasonal or intermittent watercourse, or the valley in which it flows. through Ayun named the
Ghudun with a tributary from the east—the Haluf, and another
lower down from the west—the Ghara. All these wadis are dry in
the cold weather and hot months. Although I visited the pool of
Ayun and sat in the cave overlooking it below the dry waterfall, I
was unable to get the name of the wadi A seasonal or intermittent watercourse, or the valley in which it flows. (the Ghudun of Bertram
Thomas). Then on my way to Hanun I crossed an important wadi A seasonal or intermittent watercourse, or the valley in which it flows.
known locally as Heelah (which may be Bertram Thomas’ Dauka).
Again I could get no name for the important wadi A seasonal or intermittent watercourse, or the valley in which it flows. in which Hamm
(camp) occurs, but it is the Rakibit according to Bertram Thomas’
map. I travelled eastwards from Hanun and encountered a large
wadi A seasonal or intermittent watercourse, or the valley in which it flows. in which is the Thenut spring but in this case not under
the dry waterfall where there is a cave. This may be the wadi A seasonal or intermittent watercourse, or the valley in which it flows.
Ghazal.
14. Eastwards from the Thenut spring wadi A seasonal or intermittent watercourse, or the valley in which it flows. there is an
important wadi A seasonal or intermittent watercourse, or the valley in which it flows. known as the Zaq, the rock-bed of which shows the
scour of flood water. There is a pool in the bed which may be called
Zaq and the wadi A seasonal or intermittent watercourse, or the valley in which it flows. may have another name which I failed to discover.
J“ e camp was at Har’at under the cliff of a wadi A seasonal or intermittent watercourse, or the valley in which it flows. below a dry
fall, but there was no water. It might be the Ingudan wadi A seasonal or intermittent watercourse, or the valley in which it flows.
'T^rtram Thomas). Eastwards again is an important wadi A seasonal or intermittent watercourse, or the valley in which it flows. in
which there is a large pool under a dry waterfall and in front of a
cave. The place is called Obet, but later was given as Eeyath. It
belongs to the Dhahibun wadi A seasonal or intermittent watercourse, or the valley in which it flows. system. Finally, almost on the
watershed, A1 Qutun, at Nissa (Na’Sah) camp the valley opens
northwards. The most astonishing feature of these north-flowing
wadis is the abundant evidence of flood discharges. Below the
pool at Ayun across the wadi A seasonal or intermittent watercourse, or the valley in which it flows. the width is 250 feet with flood water
signs 4 leet above the bed, and I reckoned a discharge of over
m ion cubic feet in 12 hours only. At Hanun the evidence was
similar and a 12-hour flood, on evidence there, indicated upwards
