The game hereabouts is very tame. Koodoos and giraffes stood gazing at me as a strange apparition when I went out with the Bushmen. On one occasion a lion came at daybreak, and went round and round the oxen. I could only get a glimpse of him occasionally from the wagon-box; but, though barely thirty yards off, I could not get a shot. He then began to roar at the top of his voice; but the oxen continuing to stand still, he was so disgusted that he went off, and continued to use his voice for a long time in the distance. I could not see that he had a mane; if he had not, then even the maneless variety can use their tongues. We heard others also roar; and, when they found they could not frighten the oxen, they became equally angry. This we could observe in their tones. As we went north the country became very lovely; many new trees appeared; the grass was green, and often higher than the wagons; the vines festooned the trees, among which appeared the real banian ('Ficus Indica'), with its drop-shoots, and the wild date and palmyra, and several other trees which were new to me; the hollows contained large patches of water. Next came water-courses, now resembling small rivers, twenty yards broad and four feet deep. The further we went, the broader and deeper these became; their bottoms contained great numbers of deep holes, made by elephants wading in them; in these the oxen floundered desperately, so that our wagon-pole broke, compelling us to work up to the breast in water for three hours and a half; yet I suffered no harm. We at last came to the Sanshureh, which presented an impassable barrier, so we drew up under a magnificent baobab-tree, (lat. 18d 4' 27" S., long. 24d 6' 20" E.), and resolved to explore the river for a ford. The great quantity of water we had passed through was part of the annual inundation of the Chobe; and this, which appeared a large, deep river, filled in many parts with reeds, and having hippopotami in it, is only one of the branches by which it sends its superabundant water to the southeast. From the hill N'gwa a ridge of higher land runs to the northeast, and bounds its course in that direction. We, being ignorant of this, were in the valley, and the only gap in the whole country destitute of tsetse. In company with the Bushmen I explored all the banks of the Sanshureh to the west till we came into tsetse on that side. We waded a long way among the reeds in water breast deep, but always found a broad, deep space free from vegetation and unfordable. A peculiar kind of lichen, which grows on the surface of the soil, becomes detached and floats on the water, giving out a very disagreeable odor, like sulphureted hydrogen, in some of these stagnant waters.
