disease in plants. It is important that such fungi shall be 

 studied sufficiently so that their characteristics may be deter- 

 mined not only for the immediate practical value that such 

 knowledge may have but because this work helps to l)uild up 

 the science upon which the practical phases of much of plant 

 pathology are based. For this reason, considerable attention 

 has been given to technical studies of certain fungi associated 

 with diseases of the apple. Part of these results have been 

 published and work is now in progress on a group of fungi 

 which cause disease not only in apples but in a nuiuber of otiier 

 plants which are not at all closely related. 



Each year a number of specimens of diseased plants are sent 

 in to the patholog>' laboratory from different sections of the 

 State. A record is kept of the occurrence of the disease and 

 in most cases the specimen is preserved. In many cases photo- 

 graphs are taken showing the appearance of the affected plant. 

 In addition to this, the pathologists are making observations 

 as opportimity offers on the occurrence of diseases in the State 

 other than those of the potato and the apple. Considerable data 

 has already accumulated on diseases of other cultivated plants 

 and it is expected that a bulletin will be prepared soon in 

 which these will be described together with methods for their 

 control.
