=NOTES ON THE ROAD FROM HALAIB TO PORT SUDAN.=
* * * * *

On the completion of the survey work at Halaib in May 1908, I returned to Cairo by marching in to Port Sudan and thence taking steamer to Suez. The journey from Halaib to Port Sudan with baggage camels occupied eleven days, travelling on an average thirty kilometres a day. This rate of travel did not permit of any surveying being done en route, but I took brief notes of the road and the wells on it, and as this road does not appear to be included in those described in the Sudan Handbook, I give here the notes I made. The distances are estimated from the times occupied in marching.

I would mention that from Mohamed Ghul onwards to Port Sudan there are two roads; a lower one near the sea, usually followed by the Police patrols, and an upper one which goes a little distance inland. The upper road was the one I followed, as my guides informed me that while it was only some eight kilometres longer than the lower one, there was much better water to be found on it.

In the sketch maps on Plates XXVII and XXVIII, I have shown the road and the wells on it as correctly as is possible from my notes, using the Admiralty Chart No. 2,336 as a basis for the coast-line and the maps 36 I and 46 A, issued by the Sudan Survey Department, for the position of Port Sudan and some topographical details. As the direction of march was roughly north-to-south and the total estimated distances between Halaib and Mohamed Ghul, and between Mohamed Ghul and Port Sudan, agree pretty well with those scaled from the maps after laying down the terminal positions correctly, it may be taken that the latitudes of the wells are fairly correct, while the longitudes are liable to greater error as being only rough estimations.

| | |nor regular communication.
| | |Rocks around village are
| | |limestones and gypsum, with
| | |some calcareous conglomerates.
| | |
Wadi Shellal | 4 | 4 |Road goes over sandy and
| | |gravelly undulating ground
| | |near sea. Wadi Shellal is a
| | |broad shallow wadi (scrub)
| | |coming from high mountains to
| | |the west.
| | |
Wadi Aqilhoq | 3 | 7 |Broad shallow wadi (scrub).
| | |About 19 km. up the wadi,
| | |west of the road, Bir Frukit,
| | |where there is a constant
| | |supply of better water than
| | |can be got at Halaib.
| | |
Wadi Aqwai | 4 | 11 | }
| | | } Shallow wadis with scrub.
Kreit-reit-or | 9 | 20 | }
| | |
Ti Kureitra | 2 | 22 |Four wells, about 12
| | |metres deep, lined with
| | |gypsum-slabs; about 4 km.
| | |from coast. Water bad
| | |(strongly purgative) only
| | |suitable for animals.
| | |Gypsum beds, partly covered
| | |by gravel, extend over a
| | |broad stretch round the
| | |wells. Further on, banks of
| | |calcareous grit, covered
| | |mostly with gravel.
| | |
Bir Qabatit | 18 | 40 |About 6 km. from Ti Kureitra,
| | |mass of high felsite hills
| | |called Gebel Hadarba,
| | |passed on right of road;
| | |road continues over sandy
| | |and gravelly undulating
| | |ground across shallow wadis
| | |draining from the hills.
| | |Bir Qabatit is a well in a
| | |small wadi south of the main
| | |Wadi Qabatit, about 1½ km.
| | |from the sea. Water about 5
| | |metres down, very salt, but
| | |was being drunk by the Arab
| | |patrols, who said it did not
| | |purge them.
| | |
Bir Ma-arob | 14 | 54 |Good road over coast-plain.
| | |At Bir Ma-arob, one well of
| | |bad water, strongly aperient.
| | |Well is in wadi, forming a
| | |pool about 2 metres diameter,
| | |overhung by tamarisk-bush.
| | |Water about 4 metres down
| | |from surface. NW. of the
| | |well, group of white hills,
| | |about 50 metres high, called
| | |Tishara, of calcareous grit.
| | |
Wadi Na-akreib | 8½ | 62½ |Road over sandy and gravelly
| | |plain, here crosses a broad
| | |shallow wadi.
| | |
Wadi Hamsiat | 5 | 67½ |Wadi draining into lagoons.
| | |
Wadi Waseb | 5 | 72½ |Wadi draining into a great
| | |inlet of the sea, looks like
| | |a good harbour.
| | |
Hibi Kwan | 3 | 75½ |Wadi draining into a large
| | |inlet. Coast about here much
| | |broken, with coral reefs and
| | |islets.
| | |
Bir Delaut | 12½ | 88 |Good road on to Bir Delaut.
| | |Three wells in alluvium of
| | |wadi, about 500 metres from
| | |sea. Water about 4 metres
| | |down. The southernmost well
| | |is the best. Water good.
| | |
| 3 | 91 |Road passes head of long
| | |inlet, then it passes east
| | |of a mass of limestone hills
| | |called Abu Hamama, about 200
| | |metres high. A little further
| | |on, another big inlet called
| | |Halaqa, close south of which
| | |are limestone-hills about 150
| | |metres high.
| | |
| 13 | 104 |Road passes west of limestone
| | |hills. Further on it crosses
| | |the wide and bushy Wadi
| | |Shenaab.
| | |
| 14 | 118 |Road turns sharply eastward
| | |through low hills (sandstones
| | |and grits underlying gypseous
| | |limestones, all dipping
| | |gently eastwards).
| | |
Megwel Shumab | 1 | 119 |Road passes close to Megwel
| | |Shumab, a shallow pit
| | |excavated in limestone with
| | |a little tunnel running
| | |eastwards. Water very bad,
| | |used only by animals.
| | |
| 5 | 124 |Road hitherto over undulating
| | |ground, here becomes nearly
| | |level.
| | |
Wadi Qumat Yawab | 10 | 134 |Road crosses broad shallow
| | |wadi.
| | |
Dungunab | 7 | 141 |Small village of huts and
| | |tents on coast. Good water
| | |at well about 3 km. inland.
| | |Mr. Crossland is carrying
| | |on work here in connexion
| | |with pearl-oyster industry.
| | |Meteorological station.
| | |
Tribal boundary | 9 | 150 |From Dungunab, road detours
| | |westward to round an inlet
| | |of the sea, then goes over a
| | |sandy and gravelly undulating
| | |plain with bushes and
| | |grasses. Boundary between
| | |Hamedorab and Amarar country
| | |marked by two wooden posts.
| | |
Wadi Hukeib | 3 | 153 |Road crosses wadi. High
| | |white hills, 10 km. to west
| | |of road; as seen through
| | |field-glass, these appear to
| | |be of white granite seamed by
| | |basic dykes. There is a good
| | |well, Bir Hukeit-ar, in Wadi
| | |Hukeib about 4 km. west of
| | |road and 5 km. from sea.
| | |
Wadi Yameinai | 8 | 161 |Broad wadi, wherein an acre
| | |or two has recently been
| | |planted with durra. About 6
| | |or 7 km. inland from this
| | |point, is a sheikh’s tomb,
| | |white and conspicuous in the
| | |morning light.
| | |
=Mohamed Ghul= | 8 | 169 |Small village on coast.
| | |Police fort with two decent
| | |rooms above, used by mamûr
| | |as office and quarters. No
