78 BULLETIN 677, U. S. DEPARTMENT OF AGRICULTURE. 
certain of the soils are established by four detailed maps showing ~ 
the soil types and the crops actually supported by them. These four — 
soil and crop maps represent four distinct sets of soil conditions and 
of resultant crop production. They fairly represent the range of 
soil and crop conditions within the area. 
(11) The conditions, as depicted by the several classes of maps, 
agree within reasonable limits with the opinions of nearly 1,000 
farmers in the region who expressed their soil preference for spe- 
cific crops. (See detailed soil and crop maps and Table XIII.)
