reduce the number of outbreaks. Horse owners should take 
the greatest care to smear their animals over with a little 
kerosene oil when using their animals after sunset. Theiler 
has met with great success in his immunisation of mules from 
this disease, and it is sincerely hoped that his endeavours to 
immunise horses will be crowned with success. 
The Veterinary Department have been most active in their 
endeavours to suppress contagious lymphangitis, and have 
established a quarantine station for the reception of infected 
animals. The disease runs a slow course and does not yield 
readily to treatment. There is no glanders in East Africa. 
A great menace to the pig industry of the country is a 
peculiar virulent form of swine fever. For some time past 
this disease has been under investigation and every endeavour 
is now being made to produce a serum with which to protect 
swine. Pigs do exceedingly well in East Africa, and probably 
there is no place in the world in which they can be reared so 
cheaply, for there is not only a good natural feed for them 
throughout the year, but grain is cheap and easily obtained. 
Ostrich farming is advancing rapidly, but, as in South 
Africa, the greatest care must be taken of young birds, for in 
some districts of the Protectorate the Strongylus douglassi 
has been the cause of considerable mortality. 
The death rate among imported dogs from tick fever ran 
to close on eighty-four per cent. With the discovery of the 
trypanblue treatment, by Nuttall, of Cambridge, this death 
rate has been reduced to about twenty per cent. Tubes of 
sterilised trypanblue can be obtained from the veterinary 
authorities, and all classes of dogs can now be imported 
without the grave risk which dog owners had to run before 
the introduction of this treatment. No case of rabies has 
been recorded in the Protectorate. 
From time to time the veterinarians publish articles on the 
various diseases of stock either in the Agricultural Journal or 
in leaflet form, and it is proposed to arrange a course of 
lectures for farmers.
