BULLETIN 943, U. S. DEPAETMEXT OF AGRICULTUKE. 
high charge for contract labor m Keith County, Nebr., was largely 
due to the great amount of grain hauled to market by contract 
labor, this being 66 per cent of all that was produced. 
In some districts considerable work was done with tractors. 
Unless contract work, the man hours for operating the tractor were 
included under labor costs; but obviously no cost for horse labor 
would occur. The maintenance and upkeep cost of the tractor have 
been charged under machinery costs and not as hours of tractor 
labor. 
The great variations in average labor costs, by counties, as sho^vn 
in Table XXI, are due to the variation in man and horse labor rates 
used in calculating labor costs, and to the variations in amounts of 
labor devoted to raising an acre of wheat. As previously sho^\Ti, 
considerable variation existed in the average labor rates determined 
for various counties. However, it does not necessarily follow that 
those counties having the higher labor rates had the higher total 
labor costs per acre.

MATERIALS. 
SEED. 
The most common variety of seed wheat for the spring- wheat 
districts was the Marquis, and for the winter-wheat districts the 
Turkey Ked. An average of approximately 3.5 per cent of the 
winter-wheat acreage was reseeded, while no reseeding was required 
for spring wheat.
