COTTON FLOWER AND 

 SEED HEAD 



The function of cotton fiber is, of 

 course, to protect the seed and to 

 facilitate its distribution. But nature 

 would scarcely have carried the elabora- 

 tion of the protective fiber to such a 

 length had she not been aided by man, 

 who has selected generation after gen- 

 eration among the cotton plants for the 

 ones that produced the best quality of 

 fiber, as gauged by his own needs.
