rotation. On some farms it is beginning to occupy the whole of the 
first two years. The greatest number of farms is in the group next 
below that which appears to be the most profitable. But the farmers 
here are increasing the percentage of their corn acreage very ma- 
terially, as an examination of the census statistics for the last two 
census years will show. In other words, the farmers are slowly re- 
sponding to the economic pressure tending to drive them toward a 
more profitable cropping system than that which now generally 
prevails. 
The average percentage of corn area for the entire number of 
farms (22.3 per cent) is in the group of Table X next below the 
most profitable one. This study confirms the opinion of the most 
progressive farmers of this region to the effect that they ought to 
increase their acreage of corn. 
As previously stated, corn is here grown mostly for feed. But a 
considerable number of farmers grow more of it than they need for 
this purpose, selling a small surplus. Does it pay to do this? Would 
it pay better to sell all their corn, for which they can get very good 
prices, rather than feed it to the classes of live stock kept on these 
farms? 
It was found that 127 of the 378 owners sell some corn. In fact, 
this crop constitutes the direct source of 2.3 per cent of the entire 
receipts of the 378 farms. In nearly all cases where corn 1s sold, the 
percentage of income from it is less than 20, and in only two cases 
is it more than 26. In the greater number of cases it is less than 10 
per cent. 
Table XI shows that the 251 farms that sell no corn make an 
average labor income considerably less than the 121 farms that de- 
rive from 1 to 19 per cent of their income from this source.

It evidently pays to sell some corn. Unfortunately, the number of 
farms in the next higher group is too small to give a decisive result, 
but it is significant that the average labor income of these six farms 
is exceedingly low. Apparently, it also pays to feed a part of the 
corn. 
Potatoes.—On the farms here under consideration 6 per cent of the 
crop area was devoted to potatoes. They were found on 366 of the 
3(8 farms operated by their owners. This crop is, therefore, very 
general in this region, though the acreage is usually small. In by 
far the larger number of cases the acreage, expressed in percentage of
