ing about two or three weeks later. If 1 was going to poison 

 the curculio with only one spraying I think 1 would put the 

 poison on with the second spraying. We handle the curculio 

 very well that way, and you don't have much trouble with it. 



Professor Emerson : 1 want to say a word about the frosts 

 injuring the apples. At Tecumseh we noticed injury first on 

 trees that were not sprayed, and we noticed there also that 

 the leaves were hurt ^^'orse on tlie unsprayed trees. The work 

 at Tecumseh was done with Mr. IScott of the United SStates 

 Department of Agriculture and he noticed that particularly. 

 He noticed that the leaves hanging on the unsprayed trees 

 were killed and that the trees that were sprayed came through 

 all right from the frost. 



Another thing, a question was asked when apples ought to 

 be picked. In our experience where there were sprayed and 

 unsprayed trees we found it was difficult to gauge the pick- 

 ing time and get the best results. If we picked all at once, 

 the unsprayed apples were ripe and the ones that had been 

 sprayed had not finished coloring up yet. And while we were 

 waiting until they were all ripe the apples from the unsprayed 

 trees would be on the ground. At lUair we had that experi- 

 ence and they were practically worthless except for culls. I 

 remember Mr. Marshall's apples when they were picked, when 

 those from the unsprayed trees were ready to be picked, if we 

 picked from the sprayed trees the men complained that they 

 were hard to pull off. 



Mr. President: Our next topic is "Guarding Against 

 Frosts and Freezes with Smudges and Heaters," by Mr. C. E. 

 Mincer, of Hamburg, Iowa.
