or otherwise (any artificial disturbance will cause it to spin 

 a web, and ifc will let itself down to the ground) ; or, under 

 other circumstances, it crawls out of the apples down the limb 

 of the tree and down the trunk, to where the bark is loose, 

 and finds a place there to spin its cocoon. It takes a very 

 little space: a sixteenth of an inch is abundant for him, 

 because he can gnaw as much as he wants to to enlarge it. 

 If he falls to the ground by means of his web, he evidently 

 has the faculty of seeing ; because he heads directly towards 

 the trunk, crawls up, and finds what the other has found in 

 coming down the tree, and spins his cocoon there. Then a 

 third way is, that the fruit, by means of his boring, has be- 

 come so far weakened, that it drops from the tree. In 

 that case the worm goes on feeding until it comes to 

 maturity on the ground, if not already grown, and then 

 comes out of the apple, and takes the same course that the 

 other one did that had spun down, — crawls toward the 

 trunk of the tree, goes up, and finds a place in which to spin 

 his cocoon. 



Now, the spot to trap him, apparently and really, is just at 

 the trunk of the tree. My practice has been this the past 

 year; and I have followed it very faithfully, and can give you 

 entire results. In the first place I scrape the trunk to make 

 it smooth, so that he will not have any chance to spin his 

 cocoon outside of my arrangement ; then I have a piece of 

 wrapping-paper, which I fold up, and tie round the tree. 

 I want to make as many traps for him as I can ; and I fold the 

 paper from two to three inches wide, fan fashion, and then 

 with a string it is tied about the tree, passing round the mid- 

 dle of the paper. That is tied loosely with a bow-knot, so that 

 it is very easily untied. The result is, that the worm will 

 either crawl in among the folds of the paper, or, as he seems 

 to prefer, the space between the inside of the paper and 

 the bark of the tree. Here is a paper that has been used 

 the whole season. It is ordinary thin wrapping-paper, and 

 it would almost do for another year. I put one of these 

 papers round the trunk of each tree that had been scraped 

 smooth, as I said ; and then I went round every Monday 

 morning, took off the papers, and counted the moths that 

 were in them : when I saw one, having a knife with me, I 

 wiped it across him and killed him. They must be killed
