creases. The amount of cash and supplies required per acre remains 
nearly constant except on the smaller farms, where it is somewhat 
larger. The value of the machinery 1 per acre decreases steadily 
as the size of the farm increases, as does likewise the value of the 
work stock, indicating a more efficient use of these two items of 
working capital on the larger farms. The value of productive live 
stock per acre decreases as the size of the farm increases, indicating 
more intensive farming on the smaller farms. 
The relative intensiveness of the farming on the farms of various 
sizes is shown in Table XXIV.

In studying the table it must be remembered that intensity does 
not merely mean increased yields per acre, but that it involves the 
kind and value of crops grown, the kind and number of live stock 
kept, the system of marketing, and the amount of labor put into the 
farm business. It will be noticed that as the size of the farm in- 
creases the receipts per acre, the net income per acre, the amount of 
labor per acre, and the amount of productive live stock per 100 acres 
all decrease. That is, the small farms are managed much more inten- 
sively than the large ones. This increased intensity, however, does 
not usually compensate for the difference in the number of acres 
farmed, as we have seen in Table XXI, and the larger farms there- 
fore afford better standards of living and pay better wages to the 
farmer than the small ones. This is due largely to greater efficiency 
in the management of labor, land, and capital on the larger farms, 
and to greater efficiency in the use of work stock and equipment. 
This efficiency is shown in Table XXV. 
1 The value of the machinery reported in the table is about half what it would cost if purchased new, 
since present values only of all worn or second-hand implements and machinery were asked for in taking 
the records.
