plum on, that is, for European and native varieties, and Japans talce 

 fairly well to this stock, but on account of the fact that it does not sprout 

 from the roots, it makes a very desirable stock to work plum on. Mahaleb 

 stock came from Persia orignally and is a little more tender than our 

 common cultivated varieties of cherries. Trees when j'oung and thrifty 

 will not stand as much cold as Montmorency. It is used for working 

 Morello almost exclusively. Sweet cherries used principally on Mazzard 

 stock. Mazzard and Mahaleb are varities of plum. 



Mr. Swaim: This last year I had a discouraging experience with my 

 English Morello cherries. There was a A'ery small worm affected them, 

 a maggot. There was little or no sign of anything wrong until you 

 opened the cheiTy. I would like to know what remedy there is, if any, 

 for that. They work in them when nearly ripe. 



Professor Ti'oop: I do not know what it can be unless it is plum 

 curculio. Plum curculio is the one that usually makes wormy cherries. 

 I do not think of any other that I have had any experience with. 



Professor Beach: I am soiTy to say we have that trouble and it is 

 just now most serious to cherry growing in New York State. One 

 of the most extensive cherry orchards near Geneva, of Montmorency 

 and Morello, the frait was not touched this year at all on account of this 

 trouble. The insect is the larva of a fly and the fly punctures the skin 

 of the fruit as it ripens and pushes its egg into the fruit, and as the gentle- 

 man has said, the fruit may shOAv on the outside no sign of being wormy 

 at all but it is full of little maggots or fruit flies. AVe have had it only 

 about three years and know of no remedy for it. 



Mr. Stout: I have been bothered with that in English Morello for 

 three or four years. Two years ago I sprayed with strong solution of 

 Paris. green when near full bloom, and that year the fruit was fair, but 

 I diminished the yield by spraying at that time, this year we had a good 

 crop without spraying. 



Mrs. Royer: For two years we were troubled with that, sometimes 

 there would be as high as three in a cherry, veiT small. In all our crop 

 of cherries we did not get scarcely a cherry that was fit to use. This 

 year I sprayed them about the time they were as large as a small pea 

 Avith a pretty strong Bordeaux mixture and that stayed on them all 

 summer. This year we had scarcely a wormy cherry, and we had an 

 abundance of them. Never had any more on the tree than we hud this 

 year, and they wore of a very fine quality. Whether the spraying did 

 it or not I do not know. 



Mr. Swaim: Spraying did not prevent it in my case, as I used Bor- 

 deaux pretty strong.
