States has grown from 37.5 bales in 1912 to 16, 000 bales in 1917 under the direction and stimu- 

 lation of the U. S. Department of Agriculture. Egyptian cotton grown in the United States 

 is as good as the best cotton grown in Egypt. The chief difficulties in the production of 

 this cotton in the United States arc (1) lack of reliable seed stock, and dependable varieties, 

 (2) lack of cooperation on part of growers in order that a sufficient quantity may be grown 

 to establish standards and be of commercial importance. Cultural methods, diseases, and 

 requirements of the crop are also considered. — R. G. Wigijans.
