to say that I think raspberries are hurt more by the hot sun. They 

 need shade. 



Col. X. J. Colman — I expected to have heard something in ref- 

 erence to raspberry blight. A few years ago we had hundreds of 

 acres which were abandoned on account of blight. I hoped we 

 would hear more from practical growers on this subject. It may be 

 that other places have not suffered so much as where they plant so 

 largely. 



Frof. ^wrnV^, of Illinois — We have had abundance of blight, but 

 not so much for the last year or so. I think the real agent at work, 

 where it is thought that the hot sun does it, is a kind of fungus. 

 The only hope for it that I can see is to protect the canes from dew 

 and rain, as the fungus will not spread if the canes are kept dry. 

 All that is to be done to see how the fungus will spread is to take 

 from a white spot on a cane, a little of the material and put it on a 

 healthy place. If plants are in a row, pretty thick, and are pinched 

 back, this will be prevented to some extent. 



Oliver Gibbs, Jr., of Minnesota — In inoculating, do you make an, 

 incision ? 



Prof. Burrill — Xo, sir. 



Mr. Pierce — Why does it affect certain plants? 



Prof. Burrill — Some plants are more susceptible to certain dis- 

 eases than others, just as in the case of different individuals. I have 

 heard it said that a dog will bite some people and not others. 



Mr. Pefer, of Wisconsin — I found blight on raspberries to be 

 caused by a sort of fungus. It appeared first on Davidson's Thorn- 

 less, next on Doolittle, and last on ^Mammoth Cluster, I have not 

 seen it on the Gregg. I have seen it on blackberries. I do not 

 know why there is this difference unless some bark is heavier than 

 others. 



The President — Is there a remedy ? 



Prof. Burrill — None that I know of. 



President Earle — I think, after making some announcements, it 

 will be Vjest to adjourn to attend to some other business, and it will 

 give the people a chance to become members of the Society. Any 

 one becoming a member for the present year is offered the last year's, 

 proceedings for one dollar additional.
