The work done by the Entomological Station at Rennes during 1916 

 included the preparation of an 8-page bulletin entitled " Insects 

 harmful to soldiers in the field," copies of which were sent to the men 

 at the front, together with sachets of flowers of sulphur for use 

 against Pediculus hunmnus {vestimenti) (body louse).

The chief disease with which the Veterinary Division has had to 

 deal is African Coast fever. The position in respect of this disease, 

 taking the Union as a whole, has improved. In the Cape Province 

 no fresh outbreak occurred, and it is hoped that shortly it may be 

 declared entirely free. In the Transvaal there have been several 

 new outbreaks, due to the lack of co-operation of the farmers ; while 

 in Natal the progress towards total eradication has been slow, owing 

 to the fact of there being so many absentee landowners. As the 

 majority of cases are not discovered till they have been in existence 

 for some time, and consequently the adult brown tick [Rhipicephalus 

 appendiculatus] is prevalent and infected, five-day dipping is being 

 rendered compulsory in preference to three-day dipping, hand-dressing 

 in both cases being essential. 



A few cases of trypanosomiasis have been reported in Natal, the 

 infected animals including cattle, donkeys and one mule.

A further and most important step in the eradication of sheep-scab 

 has been gained by the proclamation of protected areas, within which 

 and out of which free movement of stock is permitted, but into which 

 none may be moved without a clean certificate from the Inspector 

 of the area. 



In one district at the request of the local Farmers' Association, 

 who were very anxious to have the district freed from scab and 

 proclaimed a protected area, arrangements were made to dip all the 

 sheep in the district -within a limited period under the supervision 

 of an inspector. The results of the operations will be dealt with 

 in the next annual report. 



Scab was unfortunately spread as the result of the drought 

 experienced over nearly the whole of the Union, which necessitated 

 an unusually extensive movement of stock in search of better grazing. 

 The poor condition of such animals often made quarantining en route 

 impossible, and hand-dipping had to be resorted to till their condition 

 had improved, and the usual dippings could be administered. During 

 the year, 1,239 dipping tanks were constructed, the recommended 

 circular type gradually superseding the long and narrow one.
