Whiter Meeting. 315 



The Dewey nozzle was recomnieuded by Mr. Baxter and others 

 as the best nozzle he had used. Mr. Murray said that the Eclipse was 

 the only pump he had ever used, that a fifteen year old boy could use 

 all day with two lines of hose. 



DKY SPEAYIIsTG. 



J. J. Kiser showed a dust blower which he claimed to be far better 

 for fighting insects than water solutions. He mixed the Paris green 

 or other insecticide with dry slacked lime. The machine worked with 

 a bellows. 



Prof. Stedman said the machine was a good one for the price, but 

 he preferred the Leggett powder gun which worked with a rotary fan. 

 He thought that on the whole the water sprays would be more efiicient 

 than the dust sprays, and thought that dry lime would not neutralize 

 the corrosive property of Paris green. Dry lime and powdered copper 

 sulphate would not make Bordeaux mixture. 



L. A. Goodman and others spoke of the great labor of spraying 

 with water mixtures, and hoped the scientists would de\ise ways of 

 using insecticides and fungicides in fine powder. In some of our 

 large orchards it is hard to get water and haul it over the hills on which 

 some orchards are planted. 



Prof. Stedman said that at the station they had found dry lime 

 alone to be a good thing to dust on the trees. It drives away a great 

 many insects. Dry Bordeaux mixture must be first made in water and 

 then the water be evaporated and the mixture powdered. It is made 

 by one firm and offered for sale. He cautioned those who used poisons 

 in dry powder to be careful in handling them and not to breathe the 

 dust.
