To the Honourable 



The Minister of Agriculture. 



Sir, — I beg to submit for your approval the tenth bulletin of the 

 Central Experimental Farm, which has been prepared under my 

 direction by Mr. John Craig, Horticulturist of the Central Experi- 

 mental Farm. 



The alarming spread of fungoid diseases on fruits during the past 

 few years, and the serious losses resulting therefrom have awakened 

 much interest in this subject among fruit growers, both in Canada 

 and the United States. The simple and practical remedies recom- 

 mended in this bulletin for several of the most troublesome of these 

 parasitic growths, based on experience, both at the Department of 

 Agriculture in Washington and at the Experimental Farm in 

 Ottawa will, I trust, be thoroughly tested by those engaged in the 

 cultivation of the apple, grape and 'gooseberry, and, if used in 

 accordance with the directions given, there is every reason to 

 believe that the treatment will be successful. 



I have the honour to be 



Your obedient servant, 



WM. SAUNDERS, 



Director Experimental Farms. 

 Ottawa, 25th April, 1891.
