296 THE EXPLORATION OF THE NIGER Our island was about 218 yards long by. 328 broad. At one end, that looking up-stream, was a rocky bank, whilst the other, looking down-stream, consisted of low-lying alluvial soil, often of course submerged, dotted here, there, and everywhere with the mounds of the termites, and at this time of year completely deserted. A few fine and lofty tamarinds and other trees with large trunks but little foliage formed a regular wood, and afforded us a grateful shade; but the island as a whole, with its ant-hills, its twisted, tortuous, and leafless trunks, and its ground strewn with sharp and broken flints, presented a very wild and desolate appearance when we first landed.

Its situation, however, was really far from unpleasing, for on the deserted left bank the inundations are never very deep, and near to it rise wooded hills, with here and there perpendicular cliffs rising straight up from the river. Nearly opposite to us was one of these cliffs, white with guano or with lime, which looked to me very well suited for a permanent post. Being quite bare of vegetation, this cliff stands out against the verdure of the woods, and from the evening to the morning, from twilight to sunrise, great troops of big black monkeys assemble in it, and hold a regular palaver just as the negroes do. Often at night their cries quite alarm us, and keep the sentries constantly on the qui vive.

The whole of the riverside districts on the left bank, from Kibtachi to the Toucouleur villages up-stream, are completely deserted and of bad fame. Now and then we saw men armed with bows and arrows prowling about on a slave hunt, or deer came down to drink. The right bank is far less dreary. Opposite to us is Talibia, a little agricultural village, tributary to Say. We can make out the gables of the pointed huts surrounded by palisades and sanies or fences made of mats.
