Orange Free State. — The disease was discovered on certain farms 

 in the Boshof District, resulting in the destruction of -^9 animals. 

 In addition, six farms were quarantined as a precautionary measure, 

 but no cases occurred thereon. 



Transkei.- — No outbreaks were reported. 



6. Glanders. 



In the C^ape only 3 outbreaks were dealt with, as compared Mith 

 15 in the previous year; 12 animals died or w^ere destroyed, while 25 

 in-contacts were involved. In the Transvaal 4 outbreaks occurred 

 and 530 animals were subjected to the mallein test. A serious out- 

 break occurred at Nigel in the Heidelberg District, in connection 

 with which 373 animals were tested. There were no outbreaks in the 

 Orange Free State or Natal, and in the Transkei only one case 

 occurred, in the Tabankulu district, where the infected animal was 

 destroyed. 



7. Mange. 



This disease is widespread throughout the Cape Province, still 

 mostly in the large towns, as was the case in 1920-21 ; 105 outbreaks 

 were dealt with as compared with 148 the previous year ; 23 animals 

 died or were destroyed out of a total of 349 in-contacts. In the 

 Transvaal there were 96 outbreaks, as compared with 139 during the 

 previous year. The chief source of infection is still the Witwaters- 

 rand area, where the prevalence of the disease continues to be a 

 source of trouble. In Natal there were 9 outbreaks, as compared with 

 6 during the previous year, and in the Orange Free State 8, as com- 

 pared with 5. In the Transkei 28 cases were reported, as against 

 17 during the previous year; 14 of the fresh outbreaks occurred in 

 the Indutywa district ; 9 in Nqamakwe ; 2 each in Matatiele and 

 Umzimkulu, and one in Mount Currie. All the cases were success- 

 fully treated. 



8. Other Proclaimed Diseases. 



Epizootic Li/mphangitis. — There were 5 outbreaks of this disease 

 in the Cape Province ; 2 in Bathurst, and 1 each in Barkly West, 

 Humansdorp, and Uitenhage districts, as compared with 10 outbreaks 

 during the previous year; 6 animals died or were destroyed. No 

 outbreaks were reported in the other provinces. 



Swine Fever. — No outbreaks of this disease occurred. 



Ltnig-nckness. — No outbreaks of this disease occurred. 



9. Non-Proclaimed Diseases. 



Horse-sickness. — The usual nuniber of inoculations was con- 

 ducted. In the Transkei the disease made its appearance at Port 

 St. John's, but ceased without any undue mortality occurring. 



Quarter Evil is still prevalent and inoculations continue. 



Blue-tongue was pff-evalent in certain districts in the Cape 

 Province, notably Middelburg, Graaff-Eeinet, and Cradock. In some 

 parts the presence of the disease is attributed to the abnormal and 

 early hatchings of mosquitoes.
