By this time we were in the Kourbab country, in that part under Sheikh Hassan Bafori, who governs a branch of the tribe. We liked the mamour's messenger, Sheikh Moussa Manahm, who came on with us, very much. Four hours of very desert journeying was our portion the following day. We were a good distance from water, but some was obtained by digging, thick with sand and earth. We had thus far carried water from Wadi Gabeit. We travelled six hours, wandering through desert valleys, in which everything was dried up, with clumps of grass in it as black as if they had been burnt, and as if they had not seen rain for years. All the valleys to the west of Mount Erba seem to be arid except Gumateo or Gumatyewa, a big valley which must have water near the surface, which runs all along at the back of the range, with arid hills from 500 to 1,000 feet on either side of it. Vegetation is more abundant, and masses of arack-trees (salvadora), supposed to be the mustard-tree of the Bible, grow here, the wood of which is much esteemed for cleaning the teeth. Wadi Gumateo seems to be a favourite nursery for camels. On our way we passed many camel mothers with their infants, feeding on the arack and other shrubs. At the upper end of this valley, where we encamped for a night, Mount Erba, with its highest peak, Mount Nabidua, stands out in bold and fantastic outline. It is a remarkable range as seen from this spot, shutting off like a great wall the Soudan from the Red Sea littoral. It was a most beautiful place and there was plenty of wood, so we could have fine fires at night and burn some charcoal for future use. On February 18 we had a much more enjoyable day, for we were winding about among the mountains. Twice we had to dismount to walk over passes. One was exceedingly fine, with bold and stupendous cliffs. There were several groups of huts in the Wadi Khur, which we next reached. There is much more vegetation here, many tamarisks and other shrubs giving delightful shade. Wadi Khur is the nursery for young donkeys, many of which, we were told, from time to time escape to the higher mountain, and have established the race of wild asses to be found here. The valley has a good many pastoral inhabitants, and in the side gorges are deep pools of lovely water in natural reservoirs, in which we revelled after our somewhat limited supply further inland. Up these gorges we found bulbs, rushes, and water-plants. At our camp here our men busied themselves in decorating their locks prior to reaching Sellala. Mutton-fat is beaten in the hands till it becomes like lard, and this material the hairdresser dabs at the curly wigs of his patients; those whose curls become the whitest and stiffest deem themselves the finest.
