the plants receiving no kainit had shed 75 to 92 per cent 

 of their leaves. 



The prevalence of black rust probably accounts, at 

 least in part, for the very favorable showing made by 

 kainit in 1898, for numerous experiments recorded in 

 the bulletins of this Station show that kainit generally 

 decreases the injury from black rust. 



Fertilizer experiments luith cotton at Auburn, 1898, 1899 and 

 1900 on Experiment Station farm.
