REMEDIES. 
There is no excuse, save that of gross negligence, for allowing 
these pests to injure young fruit trees. The larval cases are so 
easily picked off at a season wdien the orchardist has abundant 
leisure, that it is easy to find time to attend to them. I have been 
in several orchards the past season in which these larvae were g 
sufficiently numerous to seriously check the healthy development 
of the trees; and I doubt not that a similar condition prevails in 
hundreds of young orchards throughout the State. In some in¬ 
stances I have found trees so infested that there was a larva lying 
in wait for almost every bud; and it is needless to state that al- 
. ready the effect of past injuries could easily be traced in the di¬ 
minished vitality of the trees. Doubtless the method, so frequent¬ 
ly mentioned above, of placing the picked cases in an open field, 
away from trees, where the larvae will starve and their parasites 
escape, is preferable to that of'burning. Or, if the young trees 
are infested with any other of the several leaf-eating species, they 
may be killed by spraying with the arsenites, as recommended 
elsewhere in this paper. 
In the nursery it is of the first importance that these pests 
should be destroyed; and the nurseryman owes it both to his 
patrons and to himself to see that the work is thoroughly done. 
It is often difficult to convince those most interested of the easy 
practicability of picking these cases off of nursery stock. I have 
in mind an instance in which a nurseryman of unusual intelli¬ 
gence, whose apple stock v r as infested by the leaf crumpler, being 
advised by one of the leading entomologists of the State to put 
boys in the field to pick them off, regarded the idea as non¬ 
sensical and impracticable; and he was only convinced of the ease 
with which the work could be performed when shown the results 
of a practical experiment made to test the matter, in which a boy 
was placed in one of the infested fields with instructions to gather 
all the cases on the young trees. In two hours thirty rows three 
hundred yards long w r ere gone over, and a half peck of the larval 
cases gathered. When shown this accumulated mass of destroyers, 
our friend was convinced, and at once hired boys to go over his 
fields. He afterwards expressed himself as surprised and highly 
pleased with the result. The larval cases w T ere picked off of ten 
acres of one year apple stock, by two boys, in one and a half 
days.
