the knowledge they claim to possess, their neighbor dare 

 not know it. This class of men should be forced by 

 the strong arm of the law to do their share in work that 

 is a public necessity. 



HOW TO EXAMINE THE TREES TO FIND LARVA. 



Open the large blade of pocket knife and take off care- 

 fully the pieces of loose bark ; examine inside part, and if 

 the larva is there, you will find nest, as shown in #, Fig. i. 

 On removing cover off nest, it will either contain larva 

 (6, Fig. i) or chrysalis (c, Fig. i). All crevices and 

 dents in the bark, and crotches, should be examined 

 carefully. Some persons throw the bark away before 

 examining it, thinking the nest is on the tree. This is a 

 mistake. 



HOW TO PROCURE SPECIMENS OF THE MOTH. 



When you find the larva, if it is not on the loose 

 bark, remove the piece of bark to which it is attached; 

 place it in a small vial, and, if in the Summer time, 

 inside of twelve days you will have a genuine specimen 

 of the moth (/ and g, Fig. i). Fruit growers can get 

 important information concerning the natural history 

 and habits of the insect pests by experiments in this way. 



BRIEF MENTION. 



The theory that the moth deposited the egg on the 

 fruit blossom, and that it remained there until the fruit 

 was grown to natural size, is a mistake. 



Supposing the moth matured from the Winter larva 

 on the first day of May, the first brood of the season 

 would reach perfection by the 2oth of June, and the 

 second brood by the i2th of August. Those matured 

 after the 2oth of August deposit the egg that produces 

 the larvce and chrysalids for the next season. 



Fruit growers should examine all boxes returned to 

 their orchards. The pest has been spread over the
