the north of Lake Albert, and there seems no reason why they 
should not extend their wanderings into the Congo forests, 
although so far observation tends to show that these herds find 
their way back again, as a rule, to the countries east of the Nile. 
Hippopotami are not very numerous in the Victoria Nyanza 
near the mouth of the Kagera. The locality does not seem very 
well suited to them. In the Kagera River itself there are more, 
and parts of the river are infested by a number of very savage 
brutes that make navigation in canoes or small boats extremely 
dangerous. Lt. Weiss, of the German Commission, was repeatedly 
attacked when in a very large canoe. He was almost upset—one 
man was dragged out by the arm, but escaped. Finally his crew 
refused to go on and ran away with their paddles. The actual 
number of hippopotami cannot be considered large in comparison 
with the huge herds in the Nile north of Lake Albert. Probably 
in the great swamps of the Kagera, considerably to the south of 
the area traversed by the Boundary Commission, the hippopotam1 
ave much more numerous. ‘The specimens secured in the Kagera 
were decidedly inferior in size and in development of ivory to 
those of the Nile. 
Rhinoceroses are extremely numerous on the right bank of the 
Kagera, especially in Karagwe. The number of these animals is 
quite remarkable, and, according to accounts received, they are to 
be met with in even greater numbers a little further south. It 
is a curious fact that no rhinoceroses are to be found on the lett 
bank of the Kagera. All those seen belonged to the common 
black African type. Stories were current of the existence of the 
White Rhinoceros on the right bank of the Kagera, but these 
rumours require confirmation. ‘The rhinoceroses appear to have 
no hesitation in frequenting the extremely steep and difficult hills 
of Karagwe. Their tracks and signs were seen up and down hills 
and on ridges which appeared more adapted to the habits of 
klipspringers or goats than of such bulky animals as rhinoceroses. 
In the virgin forest west of the lake near the mouth of the 
Kagera, in the swampy and open forest east of Koki, and in the 
Busenyi forest west of the Gambaizi group of hills, several herds 
of Buffaloes are to be found. These buffaloes are of a very 
interesting, new, large variety. They are, perhaps, the largest 
buffaloes in existence. In all, in the district referred to, there 
may be 400 or 500 buffaloes, and as their numbers are not likely 
to be interfered with, except by men armed with rifles, they may 
be considered to be firmly established again after the devastation 
caused by the great cattle-plague of some ten years back. 
In Bukanga the buffaloes wander in search of young grass, 
after the fires, as far as the hills of Ankole and Koki, from the 
forests which form their strongholds. There is one disadvantage, 
however, connected with the presence of the Buffaloes, of the 
Bland, and perhaps of other Antelopes. This is the tsetse-fly, 
and it is to be feared that as long as large herds of buffaloes and 
the greater antelopes exist, so long will the tsetse-fly make it
