consuming price was adhered to as closely as possible. Some writers consider 

 that market prices should always be charged, and this point requires thorough 

 discussion. 



The cost prices for each farm were made the basis of calculation, instead 

 of selecting average costs and applying these to all farms. Greater accuracy 

 for each farm is thus obtained, but comparison between farm and farm in the 

 same district is more difficult. 



(d) Quantity of Milk produced. — The total quantity of milk produced on 

 each farm was calculated from the weekly milk records. The Recorder weighed 

 the milk once a month, checked the weighings of the intervening weeks, and 

 made all the necessary calculations himself. 



Allowance for Manurial Values of Foods.— CuvqIvX calculations on this point 

 have been made for the second year's work at Reading. The allowance on 

 account of manurial residues varies considerably, according to the kind and 

 quantity of concentrated foods and the methods of management and storage of 

 the manure. 



Allowance for Dry Cows.— Only the food fed to the cows in milk has been 

 considered, as in tlie case of dry cows it has been estimated that the value of 

 the calf or the increased value of the fat cow will balance the cost of food 

 during the dry period. 



2. Cost of Food in Production of Milk on Three Yorkshire Fann.'i. By 

 Professor C. Crowther, M.A., Ph.D., and A. G. Euston, 

 B.A., B.Sc. 



During the last four years investigations as to the cost of food in the production 

 of milk have been carried out on a number of farms in the North and West Ridings 

 of Yorkshire. In making the estimates the purchased feeding-stuffs have been 

 taken at cost price, but for the home-grown feeding-stuffs the following arbitrary 

 scale has been used : 



Hay . 



Oat Straw 

 Barley Straw 



55."!. per ton 

 30.S. „ 

 2os. 



Mangels 



Swedes 



Turnips 



105. 6d. per ton 

 10.'. 



Grazing : 3?. Gd. per week for spring calvers. 

 During the past year detailed records have been kept on three of the farms, which 

 enable the actual costs of production of the home-grown feeding-stuffs on these 

 farms to be arrived at. 



The main features of the results are summarised in the following tables : —
