I have sent seed of this to experimenters better 

 located; and this unusually hardy dwarf cotton 

 may yet prove of value for crossbreeding purposes. 



The function of cotton fiber 

 is, of course, to protect the 

 seed and to facilitate its dis- 

 tribution. But Nature would 

 scarcely have carried the 

 elaboration of the protective 

 fiber to such a length, had she 

 not been aided by man, who 

 has selected, generation after 

 generation, among the cotton 

 plants, the ones that pro- 

 duced the best quality of fiber 

 as gaged by his own needs.
