of yield on cost per unit of production. Examining the three 

 Tables XIX-XXI it will be observed that not always does 

 the farm showing the lowest acreage cost produce at the 

 lowest cost per quarter. This point, namely the influence of 

 yield on cost, is brought out particularly clearly in the 

 Table of Barley Costs (No. XIX) in which it is seen that 

 the average cost per quarter of barley on three farms is 

 actually less than the cost on either of the farms with the 

 highest and the lowest costs per acre, owing to the very 

 high yield on the farm with a total acreage cost between 

 these two. In the following graph the relation between the 

 cost per unit of land, and the cost per unit of production 

 on a farm growing a large acreage of barley in the East 

 Midlands is shown for a period of six years. The unit 

 cost in either case for the first year (1913-14) is taken as 

 100. The increase in cost per unit of land is seen to be 

 progressive, and fairly steady, whilst the cost per unit of 

 production shows no direct relation to it.
