ification of it, for the destruction of the mature 
hoppers, is what I should recommend as being next

insects seek such winter protection as is afforded 
by old leaves, straw or grass. 
Whatever plan is adopted, there must be per¬ 
sistent and united action on the part of all the vine- 
yardists in a given locality if any thing like exter¬ 
mination is to be expected. 
It is to be hoped that all who try any of the 
above or other remedies will report their success or 
failures to the experiment station that others may 
get the benefit of their experience. If opportunity 
is offorded, experiments will be conducted at the 
station for the purpose of determining the relative 
values of the different methods of overcoming this 
insect and the results will be given to the people 
of the state through the bulletins of the station.
