COTTON rAUlETIES 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 

 varietj' 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 

 apparenth' true that varieties originating on one class of 

 soil are placed at a disadvantage when tested on a widely 

 different tj'pe of soil. 



At the Alabama Experiment Station, the varieties which 

 in recent j^ears have usually taken highest rank in yield of 

 lint per acre are Cleveland, Cook Improved, Toole, Laj'- 

 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 ootton-belt : —
