somewhat infested with the rust as they came up, and whether it is in 

 the roots or in the plant, I do not know, however, this spraying will 

 prevent it. It will prevent it except in new sprouts springing up from 

 the roots. As to variety, I have grown all the varieties mentioned, and 

 I have grown what is called the Salzer Early blackberry ; it is by tar 

 the most delicious berry I have had; it spreads over somewhat like 

 red cap raspberry or the dewberry, and is very fine. 



Mr. Goodman — Under no condition would I buy from a nursery- 

 man who had plants infested with the rust. You cannot injure the 

 leaves or the top of a plant without injuring the roots, consequently 

 you ought never, under any circumstance, to grow plants from root 

 cuttings infested with the rust. My experience has been that the 

 Kittatinay is more susceptible to the rust than any of them. 



President Evans — This subject of blackberry rust is like pear 

 blight, the more we say about it the less we know about it; I had some 

 berries that had the rust and took them out and threw them away and 

 a man came along and took some of them, and I advised him to leave 

 them alone, but he planted them and had fine berries. And that is the 

 way it goes, you cannot tell anything about it. 



Mr. Van Houten — In reference to pear blight, I think the close 

 observer will notice that the blight appears on the new succulent 

 growth and from my investigation I came to the conclusion that what- 

 ever caused the rust continued there at the surface of the ground among 

 the leaves, or in some way in the ground. I think that plants taken 

 from where there had been rust, although the roots themselves might 

 not be affected, there would be that possibility, even the probability 

 of the germ of that disease, so I wouldn't plant anything from rusted 

 plants, and I believe that rust is propagated in that way and I do not 

 think it would be well to take roots from a rusted patch ; in my ex- 

 perience I have never known of plants being taken from a rusted 

 patch, but where the rust again appeared. I believe the Bordeaux mix- 

 ture if used will cure it. Extermination, in my judgment, is the only 

 sound way when rust gets started, and then be sure and propagate 

 from plants that have not been rusted. 



Mr. Evans — I want to say that in speaking of pear blight, a privi- 

 lege has been accorded to Mr. Van Houten that has not been granted 

 to any other member of this Society for 20 years. 



As this is an experience meeting I want to state my exper- 

 ience with blackberry rust. I cultivate the Snyder, I think they are 

 about the best berry we have ; in the catalogue they are listed nine 

 points for deliciousness. I had about an acre and a half and I had 

 picked them for several years and they commenced to rust and in the
