more progressive policy the laboratory increased in size and funds were 

 more liberally supplied, more attention was paid to this disease, and it 

 was possible to enter upon a systematic course of experiments, which 

 eventually culminated in the introduction in the autumn of 1905 of the 

 preventive serum inoculation of mules which is now practised with such 

 successful results. 



It was a matter of good fortune no doubt that the Division in its 

 early days should have had the opportunity of bringing such practical 

 evidence of the value of scientific work before the people of the Colony, 

 so that the laboratory has gradually become to be looked upon not only 

 as a necessity for the prevention of the introduction of diseases from other 

 countries, but also as the farmer's best friend and adviser. 



As more and more work was thrust upon the Division the time came 

 when it was impossible any longer to attempt to meet the demands in 

 the temporary and inconvenient quarters of Daspoort. Moreover, the 

 situation, low lying at the farther end of the town and in close proximity 

 of the Kaffir and coohe locations, was extremely unhealthy ; used as a 

 depositing site before, and as a burying ground for horses during, the war, 

 it seemed as if the ground itself were infected. From 1902 to 1906 every 

 year saw the occurrence of typhoid fever amongst one or more members 

 of the staff, and that of a very virulent nature, which ended fatally in 

 several cases ; it became, therefore, a matter of necessity that a move 

 should be made to a more healthy situation. 



The enteric outbreak of the year 1906 made it urgent that the future 

 pohcy of the Government with regard to the laboratory should be decided 

 upon at once ; whether appropriate buildings should be erected and a 

 Veterinary Research Laboratory should be established as a permanent 

 institution in South Africa, or a move should be made to other temporary 

 quarters on a new site. Happily the former pohcy was decided upon 

 without hesitation, and South Africa is now able to take a place amongst 

 the older countries of Europe as a leader in veterinary scientific research.
