deaux mixture, making the first application when the leaves are 

 about one-third grown, and the others at intervals of 10 or 12 days 

 throughout the season. The leaf blight of the cherry, plum, and 

 quince, which so seriously affects trees, both in the orchard and 

 nurser}^, may be held in check by using bordeaux mixture. 



FOR PRUNE AND PLUM ROT. 



Spray with bordeaux mixture as the buds are swelling, and again 

 when the fruit has attained the size of a bean, with modified bor- 

 deaux mixture. 



FOR GUMMOSIS. 



Cut out gum pockets; split the outer bark about one-eighth of an 

 inch deep from roots to branches on three sides when sap begins to 

 flow, as all gum-infected trees are barkbound, and wash with bor- 

 deaux mixture ; care must be taken in splitting the bark not to cut 

 through to the wood ; repeat in mid-summer, if necessary, 



FOR BLACK ROT ON GRAPES. 



Spray with bordeaux mixture just as the buds are swelling, and 

 again immediately after blooming, with modified bordeaux mixture.

The combination of bluestone and lime, known as the bordeaux

 vision of vegetable pathology of the Department of Agriculture 

 has just issued a bulletin on these lines which is very timely. It 

 is four years since there was published, in Farmers' Bulletin No. 

 7, a summary of the more important methods of combatting some 

 of the destructive diseases of fruit. During this time many im- 

 provements have been made in the work, and for this and other rea-

 form, our present knowledge on the subject. The question as to 

 whether it will pay to spray has long since been answered in the 

 affirmative, so it is not necessary at this time to enter upon any 

 argument in regard to this phase of the subject. It is, further-
