DISCUSSION. 



Mr. L. H. Wilcox: Do you find rust on your newly set plants? 



Mr. J. A. Sampson: I have not been bothered very much 

 with rust on my plants. 



Mr. L. H. Wilcox: Is it not that the beds are too dry to be 

 run more than one year — the old beds? 



Mr. J. A. Sampson: Well, perhaps, somebody else here 

 could answer that question better. I could not say for sure, be- 

 cause I have not had any particular experience with the rust. 

 The reason I mentioned the rust in connection with poor winter- 

 ing was, I have noticed some plants where they had been left out 

 uncovered, and in taking those plants up the roots were found 

 defective; there were spots in the roots that appeared as having 

 been caused by swelling or shrinkage of the ground, or some 

 other cause through the freezing and thawing process. 



Mr. C. L. Smith: Did you notice whether some of the vari- 

 eties are more affected than others? 



Mr. Sampson: I grow the Wilson principally, and I under- 

 stood the Wilson had been largely affected by the rust in other 

 fields. I would like to hear from Mr. Elliot, if he is in the 

 room, as I believe he has been over the ground more exten- 

 sively, and also passed over my field during its fruiting. 



Mr. Wyman Elliot: In the course of the investigations I 

 have made this year, I found there were some varieties more 

 subject to rust than others. For instance, the Captain Jack, 

 a variety we had supposed to be one of the best fertilizers, is 

 becoming so badly diseased that many are discarding it and 

 looking for something in its place. On some plantations I 

 found there was what we call "the spot disease", affecting quite 

 a good many of the plants. It weakens the plants, and they do 

 not throw out runners as vigorously as those that are more 

 healthy. I think cultivators in general will have to look to 

 their stock pretty carefully and see that they plant nothing 

 but the very healthiest, if they wish to succeed. Of course, 

 we are learning more each year. There are new things coming 

 up each year to try our patience, and we shall have to be on 

 the alert if we wish to succeed in everything we undertake. 



Mr. Smith: I see Professor Green is here. Perhaps he can 

 give us some light on the rust. 



Professor S. B. Green: The rust of the strawberry is the 

 fungus that grows in a portion of the leaves of the plant. I 

 look upon it that the thing to do is to avoid it as far as 

 possible, but it generally comes in a place where we cannot
