than 15 per cent of that of the entire world. Georgia, Soutli 

 Carolina, Alabama, and Mississippi ranked next in the order 

 named. In addition to the states shown in Figure 146 and 

 in Table XX cotton is produced in Virginia, Florida, Mis- 

 souri, Arizona, and California. The average acreage, yield 

 per acre, and total production of cotton in the ten leading 

 States during the ten years from 1908 to 1917 are shown in 

 Table XX.

 production, 1908-1917. 



More than two fifths of the improved land in farms in 

 South Carolina and nearly two fifths of that in Texas, 

 Georgia, Alabama, and Mississippi is devoted to cotton. 

 About 7 per cent of the improved farm land in the United 

 States is planted to cotton, though its production is prac- 

 tically confined to the ten Southeastern states. The total 

 acreage of oats, a crop which is grown to some extent in every 

 state, is only slightly larger than that of cotton, while the 

 acreage in wheat is less than one and one half times the cotton 

 acreage. Corn is grown on more than three times as much 

 land as cotton. 



The average annual yield per acre for the entire United 

 States for the period from 1908 to 1917 was 179.2 pounds. 

 The lowest acre yield, 159 pounds, was that of Alabama, while 

 the highest yield in the ten important states was shown by 

 North Carolina, 242 pounds. Of the annual crop of nearly 

 13,000,000 bales, about five eighths is exported.
