at the station using the Bordeaux mixture, and with very fav- 

 orable results, indeed, but I found that after I had renewed a 

 bed by burning it off that it destroj'ed about all the fungus, so 

 that we had very little trouble with it. Since we have been 

 burning otf our beds, we have very little trouble, although this 

 year I noticed some in spots. My new bed is clean. I find 

 burning to be very reliable, as it destroys the fungus. 



Mr. Kellogg: When would you make the application? 



Prof. Green: I should begin in the summer or earlier, just 

 as soon as the mulching is removed. I think we should wait 

 until they start to grow a little. There is no use in putting on 

 the Bordeaux mixture as a remedy ; it is not a remedy. In regard 

 to the snowy tree cricket, we have had them more or less at the 

 farm, and I have had them sent to me from a good many sec- 

 tions of the country. It is sometimes quite injurious, so far as 

 I know, as this gentleman from Wisconsin has said. We have 

 it for a few years, and then it disappears, probably due to some 

 parasite, then it comes back again, and, as Mr. Cook says, it 

 works in almost anything, but I think Mr. Cook is a little mis- 

 taken in his description of the mature cricket. It is that green 

 insect that gets in the house in the fall of the year and makes 

 a chirping noise. 



Mr. Kimball: What have you to say about the anthracnose? 



Prof. Green: I saw Mr. Mackintosh's paper, and I think 

 that about covers it. I believe the best treatment is to apply 

 sulphate of copper, one pound of sulphate to twenty- five gal- 

 lons of water, and spray the canes before they are laid down. 

 That kills everything. After it gets to tne inside it may work in 

 winter. In the spring of the year, I believe it would be a grand 

 idea to spray with sulphate of copper. The Bordeaux mixture 

 is a very good remedy and safe. One thing about it is that 

 Bordeaux mixture will burn the leaves on the old growth but 

 not on the new growth. The new growth seems to have the 

 power of resisting its effects more than the old growth. The 

 time to spray is just when the shoots are coming out of the 

 ground, and perhaps after, but if you leave it until later the 

 new wood will get up in the old wood, and you cannot reach it 

 w^ithout getting it on the old wood, when it will burn the leaves 

 on the old wood. Use that treatment, and it will cure anthrac- 

 nose completely. In the Eastern states, it is a good deal worse 

 than it is here. I visited Prof. Maynard in Massachusetts, and 

 he showed me some blackberries, and he said the only thing 

 he could keep them healthy with was the Bordeaux mixture. 



About this leaf curl, no one knows anything about it. We do 

 not know the real history of it. I can remember as long ago 

 as 1882 it was very injurious. When I found it so bad here, I 

 wrote to Prof. Bailey, of Cornell, but he could give me no in- 

 formation—he had never heard anything about it. This sum- 

 mer I was at the Geneva station and looked it over with Prof. 

 Beach, and while we were walking along I asked him if they 

 had the leaf curl; he said they had none of it. I asked him to 

 wait a few moments while I looked at his raspberries. I saw 

 his Cuthberts were diseased, and I asked him what it was, and 

 he said it was leaf curl, the first he had ever seen.
