In most cases such trees could doubtless be removed without disad- 
vantage, and their removal would greatly reduce the numbers of this 
pest by lessening their favorite food supply. 
Collecting the eggs.—During the dormant period of trees, when 
the leaves are off, the egg masses are fairly conspicuous, and with a 
little practice may be readily found; it is then that they should be 
cut off and burned. Trees infested with larve during the early part 
of the year, or those in the immediate vicinity, are perhaps more 
likely to be chosen by the parent moth for the deposition of her eggs, 
and such trees at least should be searched if it is not practicable to 
extend the work to the orchard as a whole. This work may be com- 
bined with pruning to good advantage, and a lookout should be kept 
-not only for the eggs of this insect 
but for the eggs and cocoons of 
other injurious species which pass 
the winter on the trees. 
DESTROYING THE CATERPILLARS, 
Neglect to search out the egg 
masses during the winter will result 
in the appearance of the larve 
about the time the trees are putting 
forth foliage. The nests, at first 
small, are soon so increased in size 
as toattract attention. If the cater- 
pillars are destroyed as soon as the 
smallemests are: detected, this will - wera pimpia inthe act of ovipositing 
prevent further defoliation of the Ln OU ees Some- 
trees, and the rule should be adopted 
to destroy them promptly as soon as discovered. In this work either 
of two practices may be resorted to, namely, destruction by hand or 
with a torch. 
When in convenient reach the nests may be torn out with a brush, 
with gloved hand, or otherwise, and the larve crushed on the 
ground, care being taken to destroy any caterpillars which may have 
remained on the tree. 
The use of a torch to burn out the nests will often be found 
convenient, especially when these occur in the higher parts of trees. 
An asbestos torch, such as advertised by seedsmen, will be satisfactory, 
or one may be made simply by tying rags to the end of a pole. The 
asbestos or rags are saturated with kerosene and lighted and the 
caterpillars as far as possible cremated. Some caterpillars, however, 
are likely to escape, falling from the nest upon the application of the 
torch. In using the torch great care is necessary that no important
