268 TRANSACTIONS OF THE AMERICAN INSTITUTE. 



surface of the insect, dosing the spiracles so as to paralyze action 

 in that part upon which it is a})plied. 



Mr, John G. Bergen thought that some insects were not affected 

 by grease ; for instunoj, those which live on cheese and bacon. 

 Dr. Trimble said that Avhenever a bug or fly gets into the ear of 

 a person, apply a drop of oil and the insect will immediately 

 march out. 



Mr. John Crane said gas lime was one of the best protections 

 against borers he had ever found. He also tried it to keep bugs 

 from vines. He applied it too thickly or too closely, and killed 

 both. He then placed the line in a circle surrounding the melon 

 hills and found that a complete protection. 



Apple Worms. 



Mr. L. Wright Pierponl, Avrites : I Avant to give the club a 

 little of my experience about appletree worms. Last fall I read 

 in the Genesee Farmer that earthing up trees in the fall would 

 prevent injuries from mice. As I had lost trees the winter pre- 

 vious I thought I would try the experiment. Under the first tree 

 I found a nest of young appletree worms about half grown. I 

 continued the process under all my trees and found them in clus- 

 ters, of about a small handful in a place, of various sizes and from 

 one to five or six bunches under a tree. I then examined the 

 trees on which they had been through the summer, and could find 

 no nits or eggs from which it is generally thought thoy are hatched 

 in the spring. 



It has alwa3^s been a mystery to me how appletree worms could 

 .hatch from an c^^ deposited on the tree in the fall and become a 

 full wrown worm as soon as the tree besins to leave out in the 

 sprinij. Will the club investigate the sul)ject and make report. 

 With me the theory of an eg^ remaining on the tree all winter 

 and hatching out so early in the spring has collapsed. Should 

 an^- think otherwise please try the experiment, and watch the 

 hatching operation through the Aviuter and make report. But 

 don't forget to spade up under your trees ; it will pay whether 

 you find the worms or not. My trees are of three years' standing. 

 On spading them I find no w^orms : they are doing finely. 



Now I am on the subject of worms I might as well saj- sorae- 

 thino- about angleworms. For some twenty years or more they 

 have infested my garden and some portion of the time have ren- 

 dered it almost useless. Have applied sttlt, lime and ashes with
