two forms of leaf bliglit that sometimes destroy every leaf on 

 the tree liefore the fruit is matured, and the lime will have 

 no effect on the blight. The application of the Bordeaux 

 mixture is effective for the curculio and also for the blight. 



Mr. Staxley. Not everyone has this mixture. 



Mr. Hill. They can make it. 



The Chairman. I tried air-slacked lime thoroughly 

 thirty-five years ago. I followed it up for several years, 

 but it was a complete failure. 



Mr. Hill. I have grown plums and other fruits for 

 many years. I have tried air-slacked lime, wood ashes and 

 road dust, having seen them recommended, but they all 

 failed in every instance. The Bordeaux mixture is effectual. 

 I think road dust just as good as lime, and either may be of 

 some use in driving the insects away, but neither is of any 

 value in destroying blight or fungus. 



QuESTiox. What would you do with the black cherry? 

 I understand the black knot has been on the ))lack cherry 

 ever since the country was settled. 



Professor Mayistard. I never saw it on the black cherry. 

 It is very common on the red choke-cherry and it sometimes 

 appears on our cultivated cherries. At the college for ten 

 years past we have had full crops of plums every bearing 

 year. There is no difficulty in growing plums and cherries 

 if you will follow up the spraying. 



Mr. . I have found hellebore useful for the currant 



worm. I have used it clear and with one-half finely sifted 

 coal ashes, also with three-quarters coal ashes. In each case 

 it was equally effectual. 



Professor Maynard. The currant worm is a very delicate 

 insect, and coal or wood ashes or road dust will often 

 destroy it when it first hatches out, but hellebore is sure 

 death to it. 



Mr. Hill. If it is applied when the worms first appear, 

 a weak solution in water sprinkled into the centre of the 

 bush will destroy them. But I wished to ask what would 

 be the difference in the product of evaporated apples from 

 a bushel of Snow apples and a bushel of King apples. 



Professor INIaynard. I think the Snow apple would give 

 one or two pounds more of the dry product, and it would 

 be of much the best quality.
