while a fourth oceurs near the Government farm at Chimoio. The southern 
and south-western parts of this district, as well as the northern part of 
Gazaland, are very little known and practically unentered by white men. 
The southern part of the Province, including the Inyambane and Lourenco 
Marques districts, was at one time noted for the presence of tsetse. After the 
rinderpest passed over South Africa, however, the fly began to disappear, and 
we have been unable to locate a single tsetse-belt in this portion. In the 
southern corner of the Lourenco Marques district, toward the boundaries of 
Zululand and Swaziland, there is said to be tsetse. The reports are, however, 
all vague and indefinite, so that there is some doubt as to their reliability.
