Fig. 121. — Tractors are most numerous in the Corn Belt, in the S|)rinK anil Winti'r 

 Wheat Areas, and in California. In the Spring Wheat Area, on .January 1, 1!)2(». 

 about 1 fai-m in 6 had a tractor ; in the Corn Belt, in Kansas, and in California about 

 1 farm in 10 ; elsewhere in the T'nited States 1 farm in 20 to 50, except in the State.s 

 south of the Ohio and Potomac Rivers, where less than 1 farm in 10(1 had a tractor. 

 The acreage of cotton a farmer can handle is not limited by the acreag*- he can plow 

 and plant, as with wheat, or can cultivate, as with corn, but by tlie amount lie can 

 pick, and a tractor can not help In picking cotton. 



Fig. 122. — Two-fifths of the 2.000.000 automobiles on farms in the United States, 

 January 1, 1920, were in the Corn Belt (see Fig. 104). Fi-om one-half in the (ja.stern 

 portion to three-fourths of the farms in the western portion of the Corn l.oli had auto- 

 mobiles, and about half the farms in Wisconsin. Minnesota, the Dakotas. and Calitornia. 

 Eastward from the Corn Belt the proportion drops to one-third ol the larms In .New 

 York and one-fourth in New England: southward it drops to one-sevrntb in t"'; '='•',"" 

 linas and Georgia and to onf-lwentieth in Mi.ssissippi. An automobile is of little neip 

 to a negro cropper, or even a poor white tenant in the South, either in marketing iiis 

 cotton or in attending to his business.
