them. When I saw one, having a knife with me, I wiped it 

 across him and killed him. They must be killed individually; you 

 cannot get them collectively. Then the paper was immediately re- 

 wrapped around each tree. I applied the papers thus to fifty-seven 

 trees in my orchard. The first larva? were found in the papers on 

 the 22d of July. They were probably there two or three days 

 before, but there was not one there on the loth. I was told to 

 apply the papers the middle of June. This was the result. I put 

 them around at that date; but the first codling moth was not 

 found until July 22d, and could not have been there more than six 

 days, of course. I found at that time 76 worms or larva?; a week 

 later I found 59; a week later, 134; and then, 135; then, 344; then, 

 147; then, 205; 267,222; and 274 on the 23d of September. Then 

 I did not go around until the 28th of October, at which time I sup- 

 posed the season was entirely through, and I found 289, making a 

 total of 2,152 codling moth larva 1 from fifty-seven trees. I 

 trapped so many in that simple way. Part of my trees are in grass 

 land, and part in cultivated land; and I got a great many more in 

 the cultivated ground, not, perhaps, because there were more there, 

 but because the grass was an obstacle to them in finding the tree. 

 I do not know, but I suspect that, when they are in the grass, it is 

 very difficult for them to find a tree, and they spin their cocoons in 

 the grass. I have no doubt of it, and therefore, for this reason, 

 the proper place to grow trees of that kind is not where you grow 

 grass, as well as for other reasons also. 



Beside this, I have been for some years in the habit of thinning 

 all my pears; and this year, for the first time in my life, I have 

 thinned my apples, only I did not thin them half enough; but I 

 did take off all the imperfect ones. I thinned out upon the same 

 principle that I do pears, and you will excuse me if I say a word 

 about that. After the curculio has done its work (which is for me 

 a desirable one), I thin out a good many of the fruits when they 

 are about the size, or before they get to the size of an English 

 walnut. I have made a business of thinning out all my pears for 

 some years, and after a good deal of experience, I have worked up 

 an implement for the purpose. It is a little forked piece of steel, 

 bent in a peculiar way. That instrument, put on to the end of a 

 long pole, like a rake handle, is the prettiest thing that can be 

 imagined, for thinning pears especially. The only difficulty with
