A comparison of the lint production and the yield does not seem to show 

 that there is any relation between the per cent of lint and the yield of any 

 one variety on the same soil or on different soils. To illustrate: In 1905 

 Russell's Big Boll gave a yield of 616.36 pounds of lint per acre on the Edge- 

 combe farm with a percentage of lint of 31.75, while in 1908 it gave a yield 

 of 362.5 pounds per acre with a percentage of 31.95. In 1905 Russell's Big 

 Boll gave a yield of 279.39 pounds per acre on the Iredell farm with a per- 

 centage of lint of 34.98. In 1909 it gave a yield of 289.85 pounds of cotton 

 per acre with a percentage of lint of 34.10. By comparing the other varieties 

 in the same way it will be found that they bear out this same fact. 



The following table will help to bring out some other contrasts in the 

 variation in per cent of lint of the different varieties under discussion: 



*One year. tFarm discontinued. 



This table brings out the fact that with the same variety there is a greater 

 variation in the per cent of lint on the Edgecombe farm than on either of 

 the others. The most striking difference is with Russell's Big Boll and Cul- 

 . pepper's Improved. Just why this should be is unknown as no records were 

 kept of the growth of these varieties on the different farms. This table again 

 emphasizes the fact that a variety that does best on one soil or in one locality 

 will not always do best on a soil of different character or in another locality.
