PROCEEDINGS OP THE SUMMER MEETING. 79 



again among those of the east, who are much more shiftless in their methods 

 than are you Michigan men; and it is apparent that improved methods 

 come in where yellows is most prevalent. 



Mr. MoERiLL: That is just my idea of it. Have yellows and fight it 

 and you will succeed. 



The desirability of the Susquehanna peach was spoken of. Those who 

 had grown it in Oceana county said very few had been produced, but those 

 were of very fine quality. 



Mr. Packard: It bore with me better than any other variety last year. 



Mr. Farnsworth: They bud and bloom, but the least cold weather 

 causes the blossoms to drop. The buds are perfectly hardy. 



Mr. Adams and Mr. Hale said that the peach orchards which have had 

 the earliest and best cultivation now are showing the least curl-leaf; they 

 had cultivated early in order to avoid it. 



Mr. Morrill advised against too much early cultivation, so as to avoid 

 having so much tender growth exposed to cold winds. 



Mr. Meisenheimer: My earliest cultivated orchard has three times as 

 much curl-leaf as the one cultivated later. 



Mr. Farnsworth: Curl-leaf is caused by sudden changes in May, when 

 the winds are from the east and northeast. Orchards sheltered from such 

 winds have little of the disease, while those exposed have much of it. 



Mr. Markham: Cultivation has little to do with it; it's the weather. 

 Some seasons we have very little of it, some seasons much. I cultivate 

 early, to get the work out of the way, and shall continue to do so. 



Mr. Haight: It seems to be worked out to a demonstration that we 

 don't know what the cause of this disease is. 



Prof. Taft: But little is really known. In May or June comes a check 

 to the growth of the leaves, and a fungus develops. Probably cold and wet 

 weather is the cause of this. Spraying with Bordeaux mixture, early, 

 before the leaves appear, and again before and after the blossoming, will 

 greatly reduce but not wholly remove the disease. It would be entirely 

 effectual but that the cold rains wash away the fungicide. 



Mr. H. H. Pratt said he had used this method on a few trees, as a 

 matter of experiment, and with success.
