on the Western side of the British sphere of influence, which is said 
to be free from fly and an excellent cattle country. There arc a few 
animals of the Zebu type coming from German East Africa, or from 
the Ngoni Country to the East of Rhodesia. 
Goats are kept at most of the larger villages, which are relatively 
few in number. They are of a very inferior strain, small and uodei 
sized, and would appear to have been in-bred for generations. Those 
in the hands of Europeans are somewhat improved, and the rams have 
been imported from the better stock-raising districts South of the 
Kafue. 
Sheep in North-Western Rhodesia are, so far as we arc aware, 
owned mainly by settlers. In North-Eastern Rhodesia, however, 
natives own large flocks, mostly small ill-shapen animals, showing bni 
an element of Persian blood. Excepting for the smaller develop¬ 
ment of their tails, which hang straight at the tip, they are not unlike 
the Indian dumbah. 
Equines are limited to a few Europeans. They came from South 
of the Zambesi, and some of the donkeys from German East Africa.
