lands. The removal of the Akikuyu and the Masai tribes, 
with their flocks and herds, into reservations will do much 
to prevent the spread of not only East Coast fever but other 
contagious diseases of stock. In all infected East Coast 
fever districts, farmers take great risks in running imported 
animals ; for they are highly susceptible to East Coast fever 
and the mortality among them is extremely high. There is, 
however, a wide field open to the farmers of East Africa in 
building up good native herds by judicious selection and 
systematic breeding. 
Rinderpest has been very prevalent during the past two 
years in East Africa. The disease spread rapidly through 
the Masai herds on Laikipia and caused very heavy mortality 
among the cattle in the Kavirondo district. Large quantities 
of anti-rinderpest serum were produced at the veterinary 
laboratory near Nairobi, and its use has done much to 
suppress disease and prevent its spread. The disease in 
many districts is fast dying out, and with the exception of a 
small outbreak in the Nandi district, no new manifestations 
of the disease have been recorded. 
The Veterinary Department has several thousand doses of 
serum in hand should further outbreaks occur. 
Contagious Pleuro-Pneumonia .—In recent outbreaks the 
mortality from this disease has not been large. The old 
“ lunger ” makes the disease particularly difficult to eradicate, 
and there can be no doubt that there are many old lungers 
among the native herds. Tail inoculation has been carried 
out where the disease had appeared, but in some cases the 
results have not been satisfactory. The inoculation has the 
advantage of curtailing the course of the disease by shortening 
the period of incubation. 
Texas Fever ( Redwater ).—This disease is fairly prevalent 
throughout the Protectorate. Mortality among native stock 
is small. Animals when young pass through an attack of 
the disease which confers an immunity. In animals imported 
from tick-free countries, the mortality has been high, but 
since the introduction of a system of inoculation, whereby an 
animal is made to pass through a mild attack of the disease,
