made, a good active man, with a garden pump and hose attached, 

 •will sprinkle the trees very rapidly. Five minutes will be sufficient 

 for the largest of trees. The preparation is made by taking a 

 pound of arsenic to sixty gallons of water; in one or two gallons of 

 water mix the arsenic, boiling it about twenty minutes, and then 

 mixing it with the rest. While being used, it should be stirred 

 occasionally, as the arsenic settles to the bottom of the liquid, and 

 will scorch the foliage. This preparation is better than Paris 

 green and less likely to injure. 



Whale oil soap had been tried by some, but was far from being 

 efficient. Mr. Plumb also spoke of the great damage usually done 

 by the codling moth, but said that he had not seen any harm done 

 by them the present season. This may be the result of the light 

 crop of fruit last year. If there were a general effort made to de- 

 stroy this moth, in two or three years we should be nearly rid of 

 them. The more familiar we are with the habits of these our ene- 

 mies, the better we are able to meet them. The egg from which 

 the first brood of worms is hatched is deposited in the apple soon 

 after it has set. On maturity it leaves the apple, crawling down 

 the tree, or letting itself down by a web (seldom falling with the 

 apple), and seeks some sheltered place to enter the chrysalis state. 

 By placing a band of cloth or paper around the body of the tree, a 

 convenient place will be furnished them which they will take ad- 

 vantage of, where they can be easily killed. These bands should 

 be examined twice a week and alfthe worms destroyed. Vinegar 

 had been used to attract and drown them, but the bands were the 

 most successful. 



Mr. Tuttle thought the moths could be caught much more read- 

 ily in shallow dishes of vinegar than in any other way. He tried 

 it last season, at the time the second brood of moths appeared, and 

 caught more in a single dish in one night than with bands in a 

 whole week. Had put. out his dishes this spring, but caught no 

 moths; there were no moths, or it was too early for them. In 

 reply to a question whether it would not answer as well to put 

 vinegar in bottles suspended in the trees, Mr. Tuttle replied that he 

 thought wide dishes much preferable, as he had caught a much 

 larger number in them, in proportion, than in those that were 

 deeper and of small surface.
