{Visible injury to the corn resulted from the use of any of 
preparations, except in a single instance, where the emulsion 
l with soapsuds was poured on the leaves of a young hill of 
Settling in the bases of the leaves where they were rolled

i general result of these various experiments with kerosene 
•es upon the chinch-bug, it may be said that a simple 
nical mixture of water and three ner cent, of kerosene, is 
to bugs of all ages, and does not injure half-grown corn if 
id is kept well shaken up. It is possible that on more tender 
tion it might be necessary to protect the plant by first making 
! ulsion of the oil with milk or soapsuds, which can then be 
11 freely with water or suds to any desired extent. The soap 
suds emulsion seems, however, partly to mask the kerosene, 
d when common hard soap is used. Soapsuds in the propor- 
r one pound of soap to twenty gallons of water was found a 
jdiluent for the emulsion than water, but should not be applied 
its which will catch and hold a portion of it for any length 
e. The evaporation of the water will so increase the strength 
suds as to injure the plant. 
i n applied by pouring or sprinkling, about one-half pint of 
o each hill of corn was needed to destroy the bugs, from the 
[ to a height of about two feet. If some device for throwing 
y was used, a much smaller quantity would doubtless suffice. 
efined petroleum sells for about twelve cents per gallon when 
by the barrel, the cost of an effective mixture would be 
four mills per gallon, or not far from $8 for a quantity suffi¬ 
ce treat an acre of corn. By using cheaper grades of petro- 
and more effective modes of application, the cost per acre 
doubtless be reduced to about $5, exclusive of the labor of 
ation. The average value of an acre of corn at the time when it 
lly attacked by the bugs is estimated by intelligent farmers at 
nd it therefore seems likely that it will sometimes pay to 
'ae bugs in the corn-field with kerosene,—at any rate where 
is abundant and convenient, and the necessary labor can

would answer a very good purpose, going over the field at
