Dillon : In the above tabic Dillon occurred in seven 

 experiments during three years, and lost on an aver- 

 age of 5.4 per cent, of its plants. In comparing it with 

 its Cook (check), which is very susceptible to wilt, it 

 is noticed that the losses in the check are about twelve 

 times as numerous as in the case of Dillon. 



In 1913 Dillon sustained a loss of 7.4 percent at 

 Liverpool, and 15.5 percent at Brundidge. 



Modella : Modella was tested sixteen times and lost 

 on an average 14.7 percent, its loss covering a range 

 from l.G percent in 1914 at Liverpool to 35.4 percent 

 at Brundidge in 1913. It is noted that 1913 was a year 

 during which all varieties suffered badly from wilt and 

 nematodes. 



Cook (check) : The first check in the above table 

 shows that the loss of cotton plants due to wilt and 

 nematode injuries was severe in every experiment. A 

 wide range of losses from 3 percent at Notasulga in 

 1915, to 82,5 percent at Brundidge in 1914 is observed. 

 The average loss in the sixteen experiments is 40.3 per- 

 cent. 



Wood: This variety closely resembles Dillon in 

 some of its characteristics, and is almost as immune 

 to wilt as Dillon. Its loss ranged from 1.4 percent in 

 1914 to 27.5 percent in 1913. Its average loss for six- 

 teen experiments was 15.1 percent. 



Covington-Toole: In comparing this variety with 

 its nearest Cook (check) it is observed that its average 

 loss was only 10.5 percent, while the average loss of 

 the check was 40.3 percent. The loss from wilt was not 

 sufficient to seriously interfere with the stand any year. 

 During the sixteen tests it lost an average of only 10.5 

 percent. 



Tri-Cook: This new variety shows that it resisted 

 the attacks of wilt and nematodes remarkably i/ell. 

 In no experiment during the five years did it lose over 

 19. percent of its plants. Its average loss was only 7.3 

 percent. 



Cook 3/)7-6 : This variety originated at the Alabama 

 Experiment Station. In the above table it is noted that 

 its greatest loss was in 1913 at Liverpool, when 28.4 

 percent of its plants died during the growing season. 

 Its range of loss for sixteen experiments varies from no 

 loss to about 28 percent. Its average loss for five 

 years was 9.3 percent.
