factory or the viner. The nearer the farms were located to the viner, 

 the lower was the cost of harvesting (table 37).

COMPARISON OF DATA OBTAINED BY THE ACCOUNTING AND SURVEY 



METHODS 



On page 5 it is stated that the data were obtained by two methods 

 - the survey and the accounting. The detailed costs of production for 

 the farms on which the costs were obtained by each method are given in 

 table 38. The average cost per acre was substantially the same in both 

 groups of farms. The average yield per acre was higher on the farms 

 that kept accounts. This made a lower cost per ton. 



Cost figures obtained exclusively by accounts represent a selected group 

 of farms and do not represent average conditions. Accounts are very 

 useful in cost work, principally because they give the farmer himself more 

 confidence in the figures. However, if the object is to determine average 

 costs, the survey method will give the required information more 

 accurately than will the account method.
