on the other half of the seed kept in reserve from the parent of that 

 row. This seed is planted in a separate plot the following year, and 

 he has a foundation of a good strain from a single superior plant, and 

 in a few seasons he will have sufficient seed for his main crop from 

 this one plant. 



It will pay every cotton grower to select his seed. If he succeeds 

 in producing a uniform field of cotton from a superior strain, he will 

 produce a more uniform staple of a better qualitj^ cotton, and he is 

 also bound to obtain an increased yield, as all the inferior plants are 

 discarded from such a field. There is an excellent future for the 

 cotton grower who is going to make it his business to breed good cotton 

 seed. Such breeders will not only be a real asset to the industry, 

 but they will soon establish a reputation for themselves as breeders 

 of good cotton seed, and in a short time will be more than repaid 

 for their extra trouble in selecting their seed. Such breeders must be 

 careful to maintain uniformity by selection, and must not think that 

 when they have produced a uniform strain their work is completed.
