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,
