on poor land, is not profitablfe on rich land. In fact, when 

 -tested on the rich soil at the Georgia Experiment Station, 

 it ranked 24th in 1906 and 26th in 1907. 



There is experimental evidence to the effect that soil 

 and climate regulate with considerable uniformity such 

 characters as the number of bolls and seed per pound of 

 Unt cotton, and also the percentage of Unt. Data per- 

 taining to these characters, as exhibited by different 

 varieties of cotton sent out by the United States Depart- 

 ment of Agriculture in 1907 and grown at four state 

 experiment stations, are given below:

 AND THE Percentage of| Lint to Seed when the Plants were

Without exception, the bolls of all varieties were very 

 small at the Texas Station, gradually increasing in size 

 at the. Georgia and Alabama Stations and were largest 

 in every case when grown at the Louisiana Station. Also, 

 the seed were smallest in Texas, following the same order 

 as did the size of bolls. The percentage of lint was highest 

 at the Georgia Station, and, in the main, lowest at the 

 Texas Station. These results indicate quite clearly the
