Mr. Samuel Bartley, of Edgewood, Effingham county, also writes 
ne, November 20, that he used, the emulsion this season (1888) 
vith entire success in connection with ditches to arrest the prog¬ 
ress of the bugs.* 
On the other hand, a letter from Hon. E. S. Wilson, of Olney, 
lated July 17, 1888, informs me that, while the emulsion kills 
be bugs that are on the corn at the time, others come on it at 
>nce; and that he does not know of a single man who had saved 
lis corn where he had used the emulsion. 
It will be seen, however, that it was here used under the mis- 
aken idea that, once applied, it will act as a permanent repellent, 
inhere chinch bugs are excessively numerous, it should be used 
subordinate to some method for the exclusion of the insects from 
he field, and applied to those accumulating on the outer rows of 
:orn wherever they succeed in making their way across the bar¬ 
riers interposed. 
Where the attack is less severe, the emulsion may be applied 
done after the movement of invasion is substantially complete, to 
lestroy the chinch bugs along the edges of the field. Indeed, it 
s not impossible that it may be economically distributed to corn 
hroughout the field, after the hatching of the second brood, for 
he destruction of the young that do the later damage. If this 
;an be done at a cost of seventy cents per acre, there are many 
drcumstances under which it could hardly fail to be profitable. 
Dr. R. S. Peyton, of Pinckneyville, whites me of a can, carried 
>n the back, with which he finds that he can work over two or 
hree acres per day with the kerosene emulsion or hot water, be- 
ides hauling and heating the water in the field. It is possible 
hat kerosene, either pure or in the form of an emulsion more or 
ess diluted, might be mingled with fertilizers, liquid or dry, and 
hus distributed to wheat in a way to combine the beneficial effects 
>f both applications with no additional labor. 
Tobacco water .—Thinking it possible that some preparation 
heaper than the kerosene emulsion might be found equally avail¬ 
able for use, I directed experiments in August, 1888, with various 
nsecticides, the most satisfactory of which were those with tobacco 
pater. 
A strong decoction of the stems being made, August 14, a num- 
>er of chinch bugs, placed on a cloth moistened with this fluid, 
pere thoroughly stupefied in an hour, and dead in an hour and a 
talf. Tobacco water of this strength repeatedly applied as freely 
,s possible had no effect on growing grass. 
\ August 15, nine bugs were treated as above, removed when wet 
pith the tobacco water, and placed in a bag of cheese cloth. Ex- 
.mined 22 hours later, six were found dead and the remaining 
hree alive.
