iv FOREWORD 



Time" is also based on lectures delivered to the 

 students at Elsenburg (the Government College 

 of Agriculture) by a capable veterinary surgeon. 

 The book throughout is pre-eminently South 

 African work, and deals with those points raised 

 in the growing South African industry. 



There is also included a chapter by the well- 

 known dairy expert, Mr. E. O. Challis, dealing 

 with the vexed question from the farmers' point of 

 view as to why cream tests vary ; and the writer is 

 much indebted to Mr. Challis for the use of his 

 excellent pamphlet. The writer's thanks are also 

 due to those gentlemen who have so kindly supplied 

 him with photos. 



The prices and figures mentioned in Chapter III. 

 (and in fact any figures) will be criticised as too 

 high or too low, but they are the average of the 

 estimated values supplied the writer by many 

 hundreds of dairy farmers distributed over the 

 Union. In any case it is not to be expected that 

 hard and fast figures can be laid down on cost of 

 production, as this will vary with the local conditions, 

 the class of farming adopted, the individuality of the 

 cow, and also, to a great extent, on "the man 

 behind the gun." 



To make this work as popular as its size would 

 permit, and as useful as possible to those engaged 

 in the dairying industry of South Africa, has been 

 the sole aim of the writer.
