COTTON VARIETIES 293 



varieties of cotton made at all of the Experiment Stations 

 within the cotton-belt is that there is no one variety that 

 has proved most productive for all conditions of soil and 

 climate. The reason for this is easily seen. A very early 

 variety is usually the best for the extreme northern portion 

 of the cotton-belt, because of the shortness of the season 

 there; but this same variety, if carried farther south, is 

 usually surpassed in yield by later varieties, which continue 

 to make fruit through a longer season. Moreover, it is 

 apparently true that varieties originating on one class of 

 soil are placed at a disadvantage when tested on a widely 

 different type of soil. 



At the Alabama Experiment Station, the varieties which 

 in recent years have usually taken highest rank in yield of 

 lint per acre are Cleveland, Cook Improved, Toole, Lay- 

 ton, and Poulnot. It is notable that Cleveland, Cook, and 

 Toole have also occupied high positions in tests made in 

 Georgia and in several different parts of Mississippi. 

 Cook has made a good record also in several localities in 

 North Carolina. 



Leading varieties at Southern experiment stations. The follow- 

 ing table makes mention of those varieties which have, as a rule, 

 taken high rank in yield of lint per acre at the experiment sta- 

 tions in the cotton-belt :
