c. The transport of cattle from place to place should be 
forbidden as far as possible. 
Apparently healthy animals may be infected with trypanosomes. 
It is easy, therefore, to understand the dangers which lie in moving 
cattle. An infected animal might easily introduce a new, and perhaps, 
therefore, a more dangerous source of infection into a herd where the 
disease does not exist or is present only in a modified form. 
Or, again, animals may be introduced into an infected, perhaps 
apparently healthy herd, as at Kasongo, only to die of trypanosomiasis. 
For example, Kivu cattle brought to the banks of the < ongo ; I.ower ( ongo 
cattle taken up the river to Eala. Hroden (3) reports that healthy cattle brought 
to Galiema from Dolo, about six miles away, became infected with trypanosomes. 
Qlassina falfulis and big game occur about both places ; the possibilities o 
infection are equal at both. He suggests that the Dolo cattle, which had no 
immunity against the Galiema trypanosome, may have been immune to another or 
perhaps merely a less virulent trypanosome occurring at Dolo. \\ e are in entire 
agreement with him. 
The cattle from Kasongo which we had sent to Lokandu (page ^45) were in 
splendid condition. It seemed probable that they were more or less immune to 
the Kasongo trypanosome and would live for many months. Out of six amma s 
sent, two were dead and two obviously ill within nine months of their arriva a 
Lokandu. 
If for any reason, e.g., breeding purposes, it is absolutely necessary 
to move one or two head of cattle, they should be carefully examined 
tor a considerable period (months) before commencing their journey. 
While travelling every precaution should be taken to preserve them 
from fly-bites. On arrival at their destination they should be isolated 
and not drafted into any existing herd until a second examination of 
orae months' duration has been completed. 
D - Special care must be taken in the choice and main- 
e oance of posts for cattle-raising in areas where trypanoso 
fliasis is liable to occur. 
In the parts of the Congo visited, cattle did best in open plain 
-°untry, where tsetse flies (Glossina pal pal is) and big ganu 
'.antelopes and buffaloes) were rare and pasturage good. 
As Bruce first showed, big game are often infected with try pano
