(i) Practically all farms reported wagons, buggies, plows, harrows, mowers, rakes, cultivators, and 

 harness. 



With regard to the relation of yield per acre to the size of farm, it is 

 important to note that the yields on the small farms are no greater than on 

 the large. There appears to be very little relation, on the farms in this 

 district at least, between the size of farm and yield per acre for any kind of 

 crop. 



On the other hand, there is a very distinct relation between the yield 

 per acre and the labour income. The writers make this point clear by 

 tabulating the adjusted labour incomes of the farms in the district divided 

 according to the " crop index " of the group to which each farm belongs. 

 Thus, if the average quantities of different crops, a, b, c... are produced on 

 a total area x, and if on a particular farm it is necessary' to devote to the 

 production of the same quantities an area y, then the " crop index " for 

 that farm is given by xfy. 



In Table XI the farms are'divided according to the crop index of each 

 farm. It is evident that good yields (crop index 100-140) are more profit- 

 able than very high yields and much more profitable than ver>- small 

 vields.
