TRAPPING THE CODLING-MOTH. 227 



individually : you cannot get them collectively. Then the 

 paper was immediately re-wrapped around each tree. I ap- 

 plied the paper thus to fifty-seven trees in my orchard. The 

 first larvae were found in the papers the 22d of July. They 

 were probably there two or three days before, but there was 

 not one there on the 15th. I was told to apply the papers 

 the middle of June. This was my result. I put them round 

 at that date ; but the first codling-moth was not found until 

 July 22, and could not have been there more than six days, 

 of course. I found at that time 76 worms or larvae ; a week 

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

 then, 147; then, 205, 267, 222; and 274 on the 23d of Sep- 

 tember ; then I did not go round until the 28th of October, at 

 which time I supposed the season was entirely through, and I 

 found 289, making a total of 2,152 codling-moth larvae from 

 fifty-seven trees. I trapped so many in that simple way. Part 

 of my trees are in grass-land, and part in cultivated laud ; 

 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. 



Besides this, I have been for some 3^ears in the habit of 

 tlxinning 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 oS all the imperfect ones. I thinned 

 out upon the same principles that I do pears, and you will ex- 

 cuse me if I say a word about that. After the curculio has 

 done its work (which is for me a desirable one, as I told you), 

 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 : it is bent in a peculiar way as the result of long expe- 

 rience. That instrument put into the end of a long pole, 

 like a rake-handle, is the prettiest thing that can be imagined,
