196 THE STOCKFEEDER'S COMPANION 



way to remodel such an udder is now obvious, for what 

 is necessary in such cases is to commence milking on 

 the larger quarters each time, so as to give the milk 

 a chance, after the cow lets her milk down, of 

 expanding the smaller quarters. 



Machine Milking. Shortage of labour has forced 

 the attention of many farmers to milking machines, 

 who are impressed by the state of perfection attained 

 by the modern machine. By the aid of suction, 

 pulsators, etc., the natural method of milking is very 

 closely imitated, hence cows and heifers take kindly to it. 



Generally speaking, machines collect the milk in 

 cans, which receive the milk from one cow (single-can 

 system) or two cows (double-can system). Cans may, 

 however, be dispensed with by installing the "Auto- 

 matic Receiver System," which leads the milk through 

 tin-lined pipes direct to the dairy. The engine driving 

 the machine may further be used for the supply of 

 electric light in the cowhouse, etc. 



XXVII. COST OP PRODUCING MILK, KEEPING 

 DAIRY COWS, ETC. 



Dr Crowther shows in his second report (1913) the 

 average cost of producing milk throughout the year, 

 when the food only is taken into account. This varied 

 very considerably ; in fact, some of the cows produced 

 milk at half the cost of others under observation. 



In the following summary the hay is taken at 553. 

 per ton ; oat straw, 305. ; barley straw, 253. ; swedes, los. ; 

 mangels, los. 6d. ; and turnips, 8s. per ton ; grass, 33. 6d. 

 per week ; concentrated foods at cost price. 



Out of 204 cows included in the report, the average
