group of largest farms, and in these two groups the rate would be 
very close to that paid by the farms of 40 acres. Farms ranging in 
size from 40 to 160 acres pay the highest rate of interest.

There is a definite relation between size of farm and the magnitude 
of the receipts, expenses, percentage of receipts paid out in expenses, 
and the percentage of expenses paid for labor. These relations are 
shown in Table XXVII.

There is a common belief in Arizona that the expenses in running 
a small farm are much less than those incurred in operating a large 
farm. While this is true abolsutely, it is not in general true relatively. 
Table XXX shows that the percentage of receipts paid out in ex- 
penses does not vary greatly in any of the size groups, and that this 
percentage is as large on iarms smaller than 20 acres as it is on farms 
of 80 acres. On farms larger than 80 acres the percentage rises slightly, 
but the rise is not great enough to verify the common opinion. The 
percentage of expenses paid out for labor is progressively larger on
