GEOGRAPHY OF PRODUCTION. 
The geographical distribution of the 1919 wheat acreage of the 
United States is shown by the accompanTing map (fig. 1). Figure 2 
shows the counties visited in each of the spring and winter wheat 
States in the coui^se of this study. 
The northern boundary of the Cotton Belt more or less closely 
coincides with the southern boundary of the TTinter TVlieat Belt. 
Likewise the northern boundary of the TTinter TVheat Belt coincides 
with the southern boundary of the Spring Wheat Belt. Table II 
shows the acreage and production of spring and winter wheat in the 
States where records were obtained, as compared with the total pro- 
duction in the United States. Of the spring-wheat area in 1919 
about 66 per cent was in the States of ^linnesota, Xorth Dakota, and 
South Dakota. Of the winter-wheat area in 1919, over 39 per cent 
was in the States of Kansas, Missouri, and Xebraska.

During the last 70 years the center of wheat production in the 
United States has moved constantly from east to west. Seventy 
years ago Xew York was one of the great wheat-producing States. 
From Xew York the region of heaviest production has moved west- 
ward, thi^ough Ohio, southern Wisconsin, and northern lUinois, 
until now the center of production for winter wheat is in central 
Kansas and for spring wheat in Xorth Dakota. In 1919 Kansas 
produced 16 per cent and Xorth Dakota 5.7 per cent of all wheat 
grown in the United States. 
The agricultmal development of these western and northern plains 
has been largely responsible for the wheat production having kept 
pace ^vith our wheat consumption. Wlieat is not grown to any ex- 
tent in the South, because of the warm, huinid climate, which results 
in injury from fungus diseases, and also because of the competition 
with the cotton crop.
