containing many siliceous fossil trees. I observed five or six, the largest of which, situated 20 minutes' walk from the river, is 51 feet in length and 20 inclles in diameter at its largest extremity. It is l)artially buried in the sand. The peasantry splinter off fragments and use them for gun-flints, and tc) strike a light. It appeared to me that these fossils were d6m-trees (Cucifera Thebaica).

On the 8th of January I arrive(l at Amloukol, and a severe attack of fever arrested lny progress until the 24th, when, being sufficiently recovered, I resolsed to cross the desert of E3ayudah* to Khartum, a route, I be]ieve, not previously passed by any Europeantraveller. Thermometer 75?. I engagedcamelsat 25piastres eacll from Ambukol to KhartCm. My first day's journey was short, as first day's journeys always are in the East; and I rested for the night, after travelling 2w hours, at a place to which the Arabs have given the name of Berj el kuran (K:oran tower). On the 25th I travelled 71 hours, and resteel at Khor-elghanim. On the 26th 9 hours to AlJu Samud.

On the 27th, in 3 hours we reached the wells of Bayudah. Many wells have been sunk, but we found water only in three, and in very small quantities. The water is good, free from any brackish taste, thick, and of a deep yellow colour, deriving these latter properties from the soil through which it passes. The water which we had brought from the Nile was putrid and nauseous, an(l we were glad to avail ourselves of the opportunity of procuring a fresh supply. We were delayed several hours in taking a small quantity, the wells having been visite(l during the morning before we arrived by Arabs, who had drawn largely upon the springs for tlleir goats, sheep, asses, and camels. These are the orlly wells between Ambukol and E1 Hajir; the latter the point at which we met the Nile again. In the afternoon we resumed our journey, crossed a small ascent of about 70 feet, and rested for the night, after 3 hours, at Khor-el-Laban. The distance on the 27th, six hours (18 miles). On the 28thn 81 hours, to K?s Abu Deluah. On the 29th, 7 hours to E1 Atherleh. On the 30th, 8 hours to E1 Gharah. On the 31st, in 31 hours we arrived at the Nile, leaving the Desert l)etween two rocky hills, E1 Hajir, about 150 feet high, on the right, and Jebal-el-Royan (situated on an island of the same name), about 250 feet high, on our left.

I crossed the desert of Bayudah, as I have shown, between Ambukol and E1 Hajir, an(l the journey is usually lerformed in seven days, though it might with ease be made in sis. It is flat, with few hills, and those small and of easy ascent. After leaving Ambukol, the surface is alternately sand and gravel, but the sub-* 4 from its whiteness.-F. S. n t N 2
