We halted an hour near a pool, by which stands a large baobab (_adansonia digitata_); the water was so muddy, that it was scarcely possible to drink it: the Moors, to render it less disagreeable, mix with it a little treacle. This forenoon we travelled nine miles. At three o’clock we stopped for prayer, and continued our journey for the space of twelve miles to the N.E. over a tolerably rich soil, covered with _zizyphus lotus_ and a species of the gramineous tribe, the prickly seeds of which adhere to the clothes and run into the flesh; I had my feet full of them, and they caused me the most acute pain. This plant abounds in sandy soils; the negroes on the Senegal call it _khakhame_. No person ever visited the environs of that river without having been cruelly tormented by it. Fatigue, however, made me forget my sufferings, and I slept soundly. September 3rd. About one in the morning I was awakened to take a little _sangleh_,[13] and two hours afterwards commenced the preparations for departure; at five we started. The heat during the day was excessive, augmented as it was by a scorching east wind. My thirst was insupportable; perceiving a group of trees, I ran to them, thinking to find water, but was disappointed; and I must have been quite knocked up had I not met by the way with abundance of _grewia_, the yellow fruit of which, of the size of a pea, is very glutinous, though far from agreeable to the taste. I kept continually chewing it, which relieved me much. At length, about one o’clock, we reached a pool, where we rested ourselves till three. Here I quenched my thirst, and my companions bathed: we had travelled nine miles to the N.E. ¼ N. over an absolutely sandy soil. Having resumed our route to N.E. ¼ E. we came to solid ground, covered with small flints of a bright red which incommoded us much. We saw several ponds; and I remarked one on the banks of which were six baobabs of prodigious dimensions. At ten we came to a ravine where there was water: here we halted for the night. We were more fortunate in the latter part of the day than we had been in the morning; for there was no want of water, and we found in abundance a plant which I took for an _anona_, a foot high, and bearing extremely green foliage: its fruits is of the size of a pigeon’s egg, and contains several seeds; the pulp, slightly acid, is very good to eat. The Moors fell upon this fruit with avidity and devoured it; I followed their example and experienced great benefit from it, for it is an excellent thing for cooling and allaying thirst. This day’s journey had greatly fatigued me; the sharp flints on which we had to walk, had cut my feet sadly. In vain did I entreat the Moors to permit me to ride for a short time on one of the bullocks; none of them would give up his place to me, so that I was obliged to follow on foot. Accordingly, the moment we halted, I threw myself on the ground, and slept in spite of the storm which came on.
