For many of the illustrations used with this paper, and for much 

 information, I am indebted to the excellent publications of the 

 Department of Agriculture, Section of Mycology, of the United 

 States. In this important field of study a great advance has been 

 made during the last few years, and the results are proving to be of 

 immense value to fruit growers and gardeners. Many of the worst 

 problems facing the horticulturist have been satisfactorily solved, and 

 many others will be cleared up during the coming year. The im- 

 portance of a widespread dissemination of the work of these ex- 

 perimenters, in its relation to the prosperity of our province, can 

 scarcely be over-estimated.
