“The use of kerosene can hardly be expected to prove of value 
except when the bugs are massing on corn. At this time, appli 
cation to an acre or two of the field next to stubble may do mucl 
to save the rest of the field.” 
Prof. Osborn estimates the necessary cost of a thorough spray 
ing to be about seventy cents an acre—thirty cents for materia 
and forty cents for labor. 
Prof. Atkinson also reported “perfect success” with the sam( 
application, reaching the conclusion that “there is no reason whj 
all should not get rid of the chinch bug on corn, for a failure t( 
kill the bugs would arise from some fault in the application, anc 
the application can be made cheaper than a dressing of the cori 
could be made with a hoe.” 
Prom the office correspondence the following items of interes 1 
are taken. 
Mr. L. B. Sidway, of 182 Dearborn Street, Chicago, writes undei 
date of August 6, 1888, as follows:— 
“I have seen the kerosene emulsion, as recommended on page 
41 of your report on chinch bugs—1888—tried with these results:— 
“1. F. Hultgren, Verona, Lawrence Co., Mo.: 
“At the beginning of wheat harvest the bugs went into his corn 
and he at once applied the emulsion. Th6 bugs not killed lef 
the field. 
“2. G. D. Sidway, Purdy, Barry Co., Mo.: 
“The bugs had got into first four rows of corn. Applied emul 
sion and supposed all were killed. Two days later found them i 
little farther in the field, and applied emulsion—beginning two o: 
three rows ahead of any bugs—and has seen no more in the field 
“3. At my own place, Godfrey, Madison Co., Ill.: 
“The bugs had gone into corn about thirty rows, and were ir 
great numbers. Applied emulsion and have seen no more bugs— 
now two weeks. 
“I think this formula a cheap, easy, and very effective method oi 
killing the chinch bug in corn. Its use may easily be worth mor< 
to Illinois in one year than the Agricultural Department costs th< 
State in twenty.” 
A farmer of Edwards county, Dr. Bristow, living near Albion 
reported personally that he had protected his corn by the use o: 
the kerosene emulsion diluted to contain four of five per cent, oi 
kerosene, applying it twice a day to the four or five outer rows, 
covered with bugs from wheat adjoining. The insecticide was ap 
plied at first with a wisp of broom corn, but afterwards simply 
thrown upon the stalks with the hand.
