to some extent, or cause irritation of the surface of the 

 fruit ? " 



Professor Waite : "That depends on the Bordeaux. 

 Proper Bordeaux will not do that." 



Mr. Ives: "Do you use four pounds, or six?" 



Professor Waite : "Four pounds is all right." 



Mr. Ives: "I have observed in my use that it does rust 

 some, and 1 have been w^ondering whether the Bordeaux was 

 all right. It was the very finest whitewash lime, very fine, and 

 apparently all right." 



Mr. Rogers: "I would like to ask the Professor a ques- 

 tion that may be right on that line. I saw something this 

 last fall which may help that a little. I never saw it before.

Dr. Sturgis: "Mr. President: Before reading the short 

 paper which I have on the subject of spraying peach trees, I 

 want to say one word about apparatus for spraying. 1 cannot 

 help thinking, after seeing Professor Waite's pictures, that we 

 are still ahead in practical spraying apparatus. I never have seen 

 anything, which, for simplicity and adaptability, can beat some 

 apparatus which I have seen right in this state. It consists of a 

 barrel mounted, and the mount of the pump, to which is con- 

 nected a lot, perhaps thirty feet long, of half-inch hose. That 

 is connected with a piece of gas-pipe, nine feet long, set with 

 nozzles every three feet. One man drives the pump, and an- 

 other carries this pipe at right angles to the course of the wagon 

 in his hand. The man pumps, and these four nozzles deliver 

 the spray perfectly upon the rows of trees. The system for 

 regulating the flow through the nozzles enables the man to allow 

 for any irregularity that opens in the rows. If the row bends
