ed in cotton many years. The 1913 experiment was 

 located on badly infected land, while the 1914 experi- 

 ment located on a different area showed very little 

 wilt. 



The yield of the 1913 experiment was lost through 

 a mistake in picking. The advantage of one variety 

 over the others in the 1914 experiment is not great. 



Mr. Joe Russell: This experiment was located about 

 a mile north of Lowndesboro on a dark fine sandy 

 soil. It is typical of a badly infected section of 

 Lowndes County. The fertility of this soil is above that 

 of the average farm land. 



Of the wilt-resistant varieties Dix-Afifi made the least 

 gain in money value over the non-resistant variety, 

 while Tri-Cook made the largest gain, a difference of 

 $30.75 in favor of the latter variety. The average gain 

 of the wilt-resistant varieties over the non-resistant 

 is $9.75 pel" acre. It is to be noticed that the money 

 value per acre of the wilt-resistant varieties is suffi- 

 ciently great to justify the growing of cotton on land 

 highly fertilized, or naturally fertile, even if it is badly 

 infected with wilt. 



Mr. J. R. Stoiigh : This experiment w^as located on 

 badly infected soil about four miles from Notasulga. 

 The land has been in cultivation many years and slopes 

 gradually from one side of the field to the other. At 

 the time of thinning the stand of plants was almost 

 perfect, but at the time of the first count a considerable 

 number of plants had died. 



The money value of Cook 307-6 was $20.13 per acre, 

 while the average value of the non-resistant Cook 

 (check) was $12.29 per acre. An average difference of 

 $5.05 per acre in favor of the wilt-resistant varieties 

 is shown in this experiment. 



Mr. Daind Richardson : The experiments conducted 

 by Mr. Richardson were located on a coarse sandy soil 

 that had been in cultivation many j^ears. The 1915 

 experiment which was in a different location was not 

 badly infected with wilt. 



In the 1914 experiment Cook 307-6 made a total 

 value of $40.25 per acre, while the Cook (check) adja- 

 cent made only $22.46. This shows the advantage of 

 planting a wilt-resistant variety. 



In the 1915 experiment it is noticed that the differ- 

 ence between the non-resistant and the wilt-resistant
