PURE COTTON SEED A FUNDAMENTAL REQUIREMENT. 



To avoid mixture and degeneration of seed, only one variety of 

 cotton should be grown in each community or district. Many other 

 improvements may be urged, but having pure seed to plant is a basic 

 need. Where different varieties of cotton are planted in neighboring 

 fields and taken to the same gins, it is out of the question to ke-ep the 

 seed pure. The gins mix the different kinds of seed, crossing takes 

 place in the fields, the varieties are mongrelized and cease to be uni- 

 form, the fiber deteriorates in quality, and the seed becomes unfit for 

 planting. 



^At the end of this bulletin references are given to previous publications in which 

 the community features of cotton improvement have been recognized. Several paragi-aphs 

 in this bulletin have been adapted from statements of the same matters in earlier papers 

 which are no longer available for distribution.
