East Coast Fever: Pretoria District in August, 1920. 



Fresh outbreaks occurred on llie farms Kameelpoort No. 278, 

 Papkuilfontein No. 575, Zanclspruit No. 109,.Mooiplaats No. 502, and 

 Harteheestfontein No. 555. None of these outbreiks, serious 

 thouodi they are. need cause g-i^eat alarm, as with the excep- 

 tion of Harteheestfontein No. 555 they are extensions of the alreadj^ 

 infected area. Harteheestfontein is, however, in the clean area, but 

 as the disease was fortunately detected in its early stages, it is hoped 

 that the prompt steps taken to deal with it will be the means of 

 preventing" its further spread in that area. In the case of the other 

 new outbreaks referred to above, every endeavour is being made to 

 expedite the erection of tanks. 



Lung-sickness: An Outbreak. 



It is most regrettable that after being free from lung- sickness in 

 the Union for a considerable number of years, this disease has broken 

 out in the Transvaal, where, in spite of the precautions continuously 

 taken by the Department to prevent its introduction from the 

 Bechuan aland Protectorate, an outbreak of lung-sickness has occurred 

 on the farm Simson, on the Magalakwin Eiver, in the northern por- 

 tion of the Zoutpansberg District. The disease was undoubtedly 

 introduced through the illicit movement of fifteen head of cattle by 

 a native from the Tuli Block, in the southern Becliuanaland Protec- 

 torate. Immediately the outbieak was discovered and reported by 

 the police, it was decided to destroy all sick cattle and those m 

 immediate contact therewith, to the number of 110. Of these, 46 

 showed symptoms of the disease on post-mortem examination. Prior 

 to the discovery of the disease, 13 head had died, of which 8 were 

 among the cattle illegally introduced, the other 5 being cattle pre- 

 viously on the farm. The farm Simson has been placed under 

 quarantine, and all the cattle in the neighbourhood are being 

 inspected with a view to deciding what further action, if any, is 

 necessary. 



Bacon and Hani. 



We publish in this issue a short article by the Lecturer in Animal 

 Husbandry at Elsenburg on " The Pig as an Economical Producer of 

 Food," and as complementary thereto we offer the following statistics 

 on the production of hacon and ham in the Union. As is the case 

 with several of our products, the past few years have shown a marked 

 and gratifying change in our economic position, for whereas formerly 

 imports exceeded exports the reverse is now the case. Our imports, 

 which at one time were considerable, have now dwindled to a negli- 

 gible quantity, and the exports of bacon and ham have increased. 



According to the Census the number of pigs in the Union was 

 as follows : — • 



1904 679,084 



1911 1,081,600 



1918 1,043,224
