Just at dark we descended into a valley where was a small stream of water; but the ascent on the opposite side was through a species of broken ground, which I have never seen any where but in Africa. It is of the following nature. A stratum of stiff yellow clay fourteen or twenty feet thick, (which, unless when it rains, is as hard as rock) is washed by the annual rains into fissures of a depth equal to the thickness of the stratum. There is no vegetation on these places, except on the summit or original level. Amongst these horrid gullies I unfortunately lost sight of the footmarks of the asses which had gone before; and finding no way to get out, led the horse up a very steep place in order to gain the original level, hoping there to find the foot path. But unluckily the ground was all broken as far as I could see; and after travelling some little way, we came to a gulley which we could not cross; and finding no possibility of moving without the danger of being killed by falling into some of these ravines, or over some precipice, I thought it advisable to halt till the morning. On this rugged summit we fell in with Jonas Watkins, one of the sick; and with his assistance I lighted a fire. Wrapped Mr. Anderson in his cloak, and laid him down beside it. Watched all night to keep the fire burning, and prevent our being surprised by the lions, which we knew were at no great distance. About two o'clock in the morning two more of the sick joined us. Mr. Anderson slept well during the night, and as soon as day dawned, August 13th,--having found the footmarks of the asses, and having with difficulty even in day light traced our way through this labyrinth, we found Mr. Scott and three more of the sick. They too had lost their way, and had slept about half a mile to the East of us. We reached Koomikoomi at ten o'clock. This is an unwalled village, but surrounded with extensive corn fields. August 13th.--Halted; rested at Koomikoomi August 14th.--Jonas Watkins died this morning; buried him. Halted here to day to see which way Mr. Anderson's fever was likely to terminate; and in the mean time sent two loaded asses forward to Doombila, the asses to return in the evening and carry loads to-morrow morning. ° ' " Obser.
