DISTRIBUTION OF WEALTH 



at A and the least productive land in use, or mar- 

 ginal land, at B. The value of the product is rep- 

 resented by the perpendicular distance from line 

 A B to line C D'. That share of the value of the 



FIG. 4 



product represented by the perpendicular distance 

 between lines A B and E E' may be looked upon 

 as the necessary minimum required to enlist the 

 capital-goods, and that share represented by the 

 perpendicular distance between E E' and D D' 

 may be looked upon as the necessary return to 

 the farmers. The remainder, measured by the 

 perpendicular distance between lines D D' and 

 CD', varying from nothing on the margin to a 

 very large share of the gross returns on the 

 most productive land, would then represent the 

 differential rent of the land. 



Attention should be called to the fact that in 

 the illustration (Fig. 4) the lines E E' and D D' 

 are not parallel to line A B, that a larger amount
