on." 



Mr. Augur. I would like to call Mr. Halsted's attention 

 to one matter which I think he did not mention, and that is 

 a fungus which attacks the strawberry plant, which is usu- 

 ally called the strawberry rust. What have your observa- 

 tions been in regard to that ? 



Mr. Halsted. There are quite a number of fungi that 

 attack the strawberry plant. The strawberry rust is one that 

 falls in that group of rusts, something similar to the wheat 

 rust and the raspberry rust, and on account of its working 

 inside, getting all ready and then popping out all at once, we 

 do not know anything about it until the injury is done. Rust 

 or smut is a most difficult thing to treat. There are no reme- 

 dies for it that I know of. You can only take them after they 

 have done their work and try to prevent their doing the 

 same thing the next year by destroying the spores by burn- 

 ing the plant, and that would be the remedy I would suggest 

 for the strawberry rust. 



Mr. Burr, of Fairfield. I am engaged in the cultivation of 

 small fruit. I have had a great deal of trouble from straw- 

 berry blight, and by examining it with a simple microscope 

 I made up my mind tliat it was a fungus. It seems that sul- 

 phur is a cure for blight in the grape, and I wish to ask the 

 speaker whether there is any probability that it would be a 

 remedy for the blight on the strawberry. I would say, 

 further, that I have experimented somewhat with sulplun-, 

 and on my first trial, I thought I was benefited ; but from 

 repeated trials I have made up my mind that the benefit, if 

 any, is very slight. 



Mr. Halsted. I think sulphur would be very little if any 

 use at all. In the case of a fungus of that description, where 

 it is working internally, running through the tissue of the 

 plant, thoroughly investing it, liaving passed through its 

 vegetative state and gone on to the statp of producing spores, 

 the application of sulphur would be so much sulphur thrown 

 away. 



Mr. Burr. I wish to ask one other question — whether sul-
