provision for our camels. Being now without fear of the Arabs who live upon the Nile, from which we were at a sufficient distance, we with the same view to safety, declined approaching the mountains, but held our course nearly N. to a small spot of graes and white sand, called Assa-Nagga. Here our misfortunes began, from a circumstance we had not attended to. Our shoes, that had needed constant repair, were become at last absolutely useless, and the hard ground, from the time we passed Amour, had worn the skin off in several places, so that our feet were very much inflamed by the burning sand.
About a mile north-weft of us is Hambily, a rock not considerable in size, but, from the plain country in which it is situated, has the appearance of a great tower or castle, and south of it two hillocks or little hills. These are all land-marks of the utmost consequence to caravans in their journey, because they are too considerable in size to be covered at any time by the moving sands. At Assa Nagga, Assiro-baybe is square with us, and with the turn which the Nile takes eastward to Korti and Dongola. The Takaki are the people nearest us, west of Assa Nagga, and Assero-baybe upon the Nile. After these, when the Nile has turned E. and W. are the Chalgie, on both sides of the river, on to Korti, where the territory called the kingdom of Dongola begins. As the Nile no longer remains on our left, but makes a remarkable turn, which has been much misrepresented in the maps, I put my quadrant in order, and by a medium of three observations, one of Procyon, one of Rigel, and one of the middle star of the belt of Orion, I found the latitude of Assa Nagga to be 19° 30', which being on a parallel with the farthest point of the Nile northward, gives the latitude of that
