"AUG. 23d.--My last camel died to-day; thus all my horses and camels are dead, and only eight donkeys remain out of twenty-one; most of these will die, if not all. There can be no doubt that the excessive wet in all the food, owing to the constant rain and dew, is the principal cause of disease. The camels, horses, and donkeys of the Soudan, all thrive in the hot dry air of that country, and are unsuited for this damp climate. "Had I been without transport animals, my expedition could not have left Gondokoro, as there was no possibility of procuring porters. I had always expected that my animals would die, but I had hoped they would have carried me to the equator: this they would have accomplished during the two months of comparative dry weather following my arrival at Gondokoro, had not the mutiny thwarted all my plans, and thrown me into the wet season. My animals have delivered me at Obbo, and have died in inaction, instead of wearing out upon the road. Had I been able to start direct from Gondokoro, as I had intended, my animals would have delivered me in Kamrasi's country before the arrival of the heavy rains. "There is an excellent species of gourd in Obbo; it is pear-shaped, about ten inches long, and seven in diameter, with a white skin, and warts upon the surface; this is the most delicate and the best-flavoured that I have ever eaten. "There are two varieties of castor-oil plant in this country--one with a purple stem and bright red veins in the leaves, that is remarkably handsome. Also a wild plantain, with a crimson stem to the leaf; this does not grow to the height of the common plantain, but is simply a plume of leaves springing from the ground without a parent stem." "Aug. 30th.--Mrs. Baker and I made a morning call for the first time upon old Katchiba by his express desire. His courtyard was cemented and clean, about a hundred feet in diameter, surrounded by palisades, which were overgrown with gourds and the climbing yam, Collolollo. There were several large huts in the inclosure, belonging to his wives; he received us very politely, and begged us to enter his principal residence; it was simply arranged, being the usual circular hut, but about twenty-five feet in diameter.
