disease resembles very strongly the "Bangle Blight"" of potato 

 (Cunningham (7) PI. I. Fig. 9. 10). Infections upon jute seedlings 

 gave a mortality of 80",, of infected plants; infections upon the nud- 

 berry did not give any decisive results. Plants which were infected 

 in July hved until November, when both infected and uninfected 

 plants died owing to the cold weather. Examination of the former, 

 however, showed tliat the fungus had destroyed the phloem and was 

 penetrating the wood at the seat of infection. 



Cotton. — In June 1911 a di.sea.se of cotton occurred on the Cawn- 

 jiore Farm. Specimens of infected seedlings sent from Cawnporc 

 had a soft yellow patch mi the lower portion of the livj)ocoty! 

 ( PI. IV. Fig. 1 ), and in bad ca.ses the rot was suflicient to cau.se collapse 

 of the seedling. Microscopic examination levealed the presence in 

 the rotted area of numerous Rliizodonia-\\\<v hvpha^ which grew in 

 all (.lirectioue from the pith to the cortex ; sclerotia were not present.
