338 Report OF THE ENTOMOLOGISTS OF THE 
Use green arsenite or other equally good arsenical, 1 pound | 
to 100 gallons of water, with the addition of enough freshly-slaked 
lime to make the mixture slightly milky in appearance. One 
pound of whale oil soap to about 20 gallons of the mixture may 
be added with good results. It will do no harm to use the’ soap 
stronger. 
Spray newly-planted fields with the poison until the willows are 
large enough for the machines. | 
After the willows are too high to spray thoroughly by ordinary 
means, use the machines for catching the insects if necessary. 
_ Urge the importance of a united effort on the part of all inter- 
ested in willow growing.
