the worm is matured, when matured it crawls out and 

 seeks a place to form its cocoon : it may be to the body 

 of the tree, to the stone wall, rail fence or some other 

 place, as most convenient. 



I have repeatedly picked up the wormy apples soon 

 after they have fallen from the trees, cut them, and found 

 much the greater part without worms, they having ma- 

 tured, as was supposed, and left the apple to cocoon. It 

 thus appears that not so much is gained by picking up the 

 wormy apples and destroying them, as has been by some 

 supposed. To get further information, I picked up wormy 

 apples, put them into a firkin with small scraps of cloth 

 and covered the firkin. I soon found cocoons in the 

 scraps of cloth, which were removed to a glass jar. Early 

 in August moths were seen fluttering in the jar. Desir- 

 ous of more information, I wrote to Professor Sanborn of 

 the Historical Institution, of Worcester, Mass., now de- 

 ceased, a man who was known to have had long experi- 

 ence in studying the habits of insects, and received the 

 following information : The moths come out in spring 

 and lay their eggs as I have described ; that he had with- 

 in his experience of more than thirty years examined with 

 a microscope a large number of female moths, and found 

 them to contain about three hundred eggs each. They 

 live two or three weeks only, laying their eggs singly on 

 the apples. If the nights are quite cool they remain tor- 

 pid, do not move out, or if the weather is wet they remain 

 quiet ; should the weather continue cold and wet, they 

 sometimes die without laying all their eggs. 



He also informs us that the worms propagate and sub- 

 sist on the following kinds of fruit : apples, pears, quin- 

 ces, cranberries, and some wild fruit, and these only. In 

 the most of our orchards apples are the only fruit pro- 

 duced on which they subsist. Then if there is a failure of
