of manure hauled per acre, greater adaptability of land to corn 

 production, and better management and skill in growing corn. 



The harvesting labor is not influenced so much by the size of the 

 machinery used as by variations in yield and the distance that the 

 corn is hauled from the field to the silo. The influence of distance 

 does not appear in the average figures because the average distance 

 is likely to be very much the same for the various States, but the 

 influence of yield on harvest labor is clearly shown by the difference 

 between the New York and the Minnesota figures.

a Excluding interest on land. 



The cost for seed is very small compared with the seed cost for 

 many other farm crops. The range from 10 pounds per acre in 

 Iowa to 24 pounds in New York is therefore not of much importance 

 from the cost standpoint but is of interest in that it indicates dif- 

 ferent practices in the two States. 



Much of the silage corn is cut and bound with the binder. Some 

 of it is cut loose, but the percentage of the corn handled in this way 

 is extremely small. The quantities of twine given in these records 

 can therefore be considered as fair figures to use when determining 

 the cost of corn harvested with the binder. 



Corn responds very well to manuring and therefore receives most 

 of the manure produced on the farms where it is grown. On the 

 Wisconsin farms the records show that although corn does not 

 occupy more than about one-fourth of the crop area it receives over 

 half of the available manure. 



Gasoline, coal, and wood were all used for fuel in filling silos, but 

 the number of farmers using wood was so small that it disappears in 

 an average. Because of the fact that the Ohio records give only 

 the value of the fuel used and not the quantity it was impossible to 

 determine the quantity of fuel for that State, but by comparing 

 values it would seem that the fuel consumed would approximate 

 that consumed in New York.
