greater virulence than anything known in Assam, but this 

 will not be known with certainty until the close of the 

 present or perhaps another season. A popular account of 

 the disease is given in tlie Agricultural Journal of India 

 for April, 1910, and a fuller report is in the press as a 

 bulletin. 



Other Tea Diseases. — Mr. Shaw is engaged in the study 

 of the obscure canker of tea, which has long been known 

 but the cause of which is still not ascertained. A disease 

 of tea seed was investigated, but the cause was not defi- 

 nitely discovered. 



Pahn Disease. — The campaign having as its object to 

 prevent the spread of the bud-rot of palms on the East 

 Coast and to stamp it out within the affected area was 

 prosecuted with energy by the executive officer in charge,

 of inspection early in the present year. Recommendations 

 for continuing the work have been made, especially for its 

 energetic prosecution in Kistna District, where it has been

 put in charge of work in Kistna as well as in Godavari 

 from January last and this led to better work. A full 

 account of the disease and measures taken to check it is in 

 the press as a memoir. Mr. McRae enquired into a disease 

 of palms at Bapatla in December but found it was not 

 f ung;al. The coconut root disease in Travancore mentioned 

 in last report is engaging the attention of the newly started 

 Agricultural Department of that State, and measures have 

 been taken on the lines suggested to prevent its spread. 

 The cultivators of neighbouring districts have been warned 

 through vernacular pamphlets of the danger of introducing 

 certain coconut produce from Travancore. 



Sugarcane Diseases. — The work in connection with 

 these has not yet reached the stage of publicatiion. Field 

 experiments on the methods of infection of red rot having 

 developed unexpected difficulties, it will probably be neces-
