188 THE PRACTICAL SIDE OF 



Let us take another case for analogy. The 

 experienced farmer who has been accustomed 

 to employ artificial manures is aware from 

 what he has already accomplished that the 

 sum he expends in the purchase of 3 cwt. of 

 superphosphate and 1 cwt. of nitrate of 

 soda may be returned in the crop with 50 per 

 cent, interest, and in consequence he invests 

 his money in the purchase of these fertilisers. 

 It is precisely the same with the cow. Where 

 the trouble is taken to ascertain how much 

 milk a cow yields and how much fat that 

 uiilk contains a buyer is justified in paying 

 a higher price. Nor is it possible to determine 

 the approximate yields of two cows of similar 

 type standing side by side, for one may 

 produce 700 gallons of rich milk and the other 

 500 gallons of poor milk. Although it is 

 impossible to ignore the fact that some men 

 are better judges of a cow than others, yet 

 there is no royal road to the selection of 

 milking stock, still less of cows which give 

 rich milk. In support of this statement 

 it may be remarked that for many years the 

 writer has examined the cows which are placed 

 in competition for three sets of prizes at the 

 London Dairy Show. They are first judged, 

 and the prizes awarded, upon the basis of
