Our first sight of the Tana River was from the top of a bluff. It flowed below us a hundred feet, bending at a sharp elbow against the cliff on which we stood. Out of the jungle it crept sluggishly and into the jungle it crept again, brown, slow, viscid, suggestive of the fevers and the lurking beasts by which, indeed, it was haunted. From our elevation we could follow its course by the jungle that grew along its banks. At first this was intermittent, leaving thin or even open spaces at intervals, but lower down it extended away unbroken and very tall. The trees were many of them beginning to come into flower.
Either side of the jungle were rolling hills. Those to the left made up to the tremendous slopes of Kenia. Those to the right ended finally in a low broken range many miles away called the Ithanga Hills. The country gave one the impression of being clothed with small trees; although here and there this growth gave space to wide grassy plains. Later we discovered that the forest was more apparent than real. The small trees, even where continuous, were sparse enough to permit free walking in all directions, and open enough to allow clear sight for a hundred yards or so.
Furthermore, the shallow wide valleys between the hills were almost invariably treeless and grown to very high thick grass.
Thus the course of the Tana possessed advantages to such as we.
By following in general the course of the stream we were always certain of wood and water. The river itself was full of fish-not to speak of hundreds of crocodiles and hippopotamuses. The thick river jungle gave cover to such animals as the bushbuck, leopard, the beautiful colobus, some of the tiny antelope, waterbuck, buffalo and rhinoceros. Among the thorn and acacia trees of the hillsides one was certain of impalla, eland, diks-diks, and giraffes. In the grass bottoms were lions, rhinoceroses, a half dozen varieties of buck, and thousands and thousands of game birds such as guinea fowl and grouse. On the plains fed zebra, hartebeeste, wart-hog, ostriches, and several species of the smaller antelope. As a sportsman's paradise this region would be hard to beat.
We were now afoot. The dreaded tsetse fly abounded here, and we had sent our horses in via Fort Hall. F. had accompanied them, and hoped to rejoin us in a few days or weeks with tougher and less valuable mules. Pending his return we moved on leisurely, camping long at one spot, marching short days, searching the country far and near for the special trophies of which we stood in need.
It was great fun. Generally we hunted each in his own direction and according to his own ideas. The jungle along the river, while not the most prolific in trophies, was by all odds the most interesting. It was very dense, very hot, and very shady. Often a thorn thicket would fling itself from the hills right across to the water's edge, absolutely and hopelessly impenetrable save by way of the rhinoceros tracks. Along these then we would slip, bent double, very quietly and gingerly, keeping a sharp lookout for the rightful owners of the trail. Again we would wander among lofty trees through the tops of which the sun flickered on festooned serpentlike vines. Every once in a while we managed a glimpse of the sullen oily river through the dense leaf screen on its banks. The water looked thick as syrup, of a deadly menacing green. Sometimes we saw a loathsome crocodile lying with his nose just out of water, or heard the snorting blow of a hippopotamus coming up for air. Then the thicket forced us inland again. We stepped very slowly, very alertly, our ears cocked for the faintest sound, our eyes roving. Generally, of course, the creatures of the jungle saw us first. We became aware of them by a crash or a rustling or a scamper. Then we stood stock listening with all our ears for some sound distinguishing to the species. Thus Icame to recognize the queer barking note of the bushbuck, for example, and to realize how profane and vulgar that and the beautiful creature, the impalla, can be when he forgets himself. As for the rhinoceros, he does not care how much noise he makes, nor how badly he scares you.
Personally, I liked very well to circle out in the more open country until about three o'clock, then to enter the river jungle and work my way slowly back toward camp. At that time of day the shadows were lengthening, the birds and animals were beginning to stir about. In the cooling nether world of shadow we slipped silently from thicket to thicket, from tree to tree; and the jungle people fled from us, or withdrew, or gazed curiously, or cursed us as their dispositions varied.
While thus returning one evening I saw my first colobus. He was swinging rapidly from one tree to another, his long black and white fur shining against the sun. I wanted him very much, and promptly let drive at him with the 405 Winchester. I always carried this heavier weapon in the dense jungle. Of course Imissed him, but the roar of the shot so surprised him that he came to a stand. Memba Sasa passed me the Springfield, and Imanaged to get him in the head. At the shot another flashed into view, high up in the top of a tree. Again I aimed and fired. The beast let go and fell like a plummet. "Good shot," said I to myself. Fifty feet down the colobus seized a limb and went skipping away through the branches as lively as ever. In a moment he stopped to look back, and by good luck I landed him through the body. When we retrieved him we found that the first shot had not hit him at all!
At the time I thought he must have been frightened into falling;but many subsequent experiences showed me that this sheer let-go-all-holds drop is characteristic of the colobus and his mode of progression. He rarely, as far as my observation goes, leaps out and across as do the ordinary monkeys, but prefers to progress by a series of slanting ascents followed by breath-taking straight drops to lower levels. When closely pressed from beneath, he will go as high as he can, and will then conceal himself in the thick leaves.
