“West of Lake Naivasha the plateau is covered for the most part with dense, almost impenetrable forests, but farther north the scenery becomes more park-like, the forest clumps being intersected with grassy ranches, which open out on to the broad expanse of the Angata Nyuki, the latter extending right up to the eastern boundaries of Kavirondo. The whole of this district is frequented by _B. jacksoni_, which is also found north of Lake Naivasha in the localities bordering on Lakes Nakuro and Baringo north and west of these points; again, it inhabits the Suk country, Chibchangnani, Turquel, Karamojo, and possibly Turkana; whilst farther west it is common in the district round Mount Elgon, and is generally met with throughout Upper Kavirondo, Usoga, and Uganda, wherever the conditions are favourable. “I have seldom encountered _B. jacksoni_ in large herds, though in habits it differs very little from other species of Hartebeest. More frequently it is met with in small groups, in twos and threes, or singly. It would appear to change its locality to a very great extent according to the seasons. Thus, during the dry months of the year it will be found plentifully scattered over the highlands, from whence it retreats to the low country at the approach of the rains. In illustration of this, I would mention that when on my journey to England in 1892, in the month of December, the lowlands at the foot of the escarpment were almost entirely deserted, whilst on the high plateau above I met with these Antelopes in great numbers. “On my return journey in the month of July of the following year the Angata Nyuki had become very swampy, owing to the heavy rains, and was entirely deserted, save by one or two odd specimens, whereas the district around Lake Nakuro, in the low country, was fairly overrun by these Antelopes. “When herding together these animals are commonly found (like _B. cokei_) in company with Zebras and other Antelopes, and I have frequently come across and shot Topi (_Damaliscus jimela_) amongst them, the latter being very numerous in the province of Buddu in Uganda. “Like all Hartebeests, _B. jacksoni_ is, as a rule, very shy and difficult to approach--though, on one occasion, having gone considerably to the south of the ordinary caravan-route across the Angata Nyuki, I not only met with them in great numbers, but they were so little alarmed by my appearance in so unfrequented a locality, that they allowed me to walk right up to them, and even when fired at only ran for a short distance. They do not appear to patronize the bush country like _B. cokei_, though they frequent its vicinity. “I remarked this specially when in Uganda, for on the only occasions on which I encountered _B. jacksoni_ there it was confined to certain open portions of the country bordering the Nile and a flat open plain of some 10 miles in diameter to the south of the Katonga River in the Buddu district, where I found it accompanied by Topi, Waterbuck, and Kob.
