BISULPHIDE OF CARBON ROUTED THEM. 
Hubbard, O., January 5, 1893. 
Editor Southwestern Miller:— In. 1890 and. 1891 my mill was 
overrun with black weevils. They got into the wheat, in the 
flour in bins, in the flour in sacks, and in fact got everywhere 
except away and into the next county. After burning large quan- 
tities of sulphur and brimstone, scrubbing with whale oil soap, 
sprinkling with insect powder, saturating screenings bin with coal 
oil, and trying all the remedies suggested in and through the 
various milling journals without avail — as they multiplied on 
the face of the earth, or rather in the mill — as a last resort I 
purchased 100 pounds of bisulphide of carbon from Edward R. 
Taylor, of Cleveland, O. After following instructions to thor- 
oughly clean up the mill, remove all bags, sacks, flour, etc., to 
as much as possible allow the vapor to circulate in and near 
their hiding places, and to make the mill as nearly air-tight as 
possible, I then procured 100 soup plates, and put fifty pounds 
in the lower story and fifty pounds in the second story, both 
distributions placed as near the 'ceilings as we could place 
them. This was done Saturday afternoon. When the fires were 
all out we filled the plates with bisulphide — being careful to 
keep above the fumes — and allowed no lights about. When this 
was done we locked the doors and did not go near till Monday 
morning, when we opened all the mill doors and windows to 
allow any remaining fumes to blow away. We then removed 
the plates, and on close examination not a live weevil could be 
found in all the mill, nor were any seen until this last spring, 
and then only a few. Another fifty pounds of bisulphide would 
have completely removed them, but as I had rented the mill I 
did not get any more. Now the secret of perfect success is in 
first getting at their haunts, which are dirty corners, screenings 
piles and heated wheat — clean up the dirt, remove the screenings 
if practicable and stir up the wheat if convenient, and then use 
enough of the bisulphide of carbon. Don’t evaporate only fifty 
pounds in a place where 100 pounds are needed and expect good 
results. Resort to heroic treatment at the start and you will 
be satisfied with the results. To persons whose mills are alive 
with weevils— and their name is legion — we have this advice to 
offer: Write to Mr. Taylor and get ready to open the campaign 
against the insects early in the spring before they have time 
to hatch out the new crop, and all desirable information will be 
cheerfully given. Respectfully yours, A. B. SHOOK.

BISULPHIDE OF CARBON FOR WEEVIL. 
[From the American Miller of Nov. 1, 1891.1 
Editor American Miller:— In my last letter I promised to 
give my experience with bisulphide of carbon on my crop of 
weevil in mitey big doses. 
I cleaned up the mill on a Saturday, removed all barrels, 
bags, etc., where the weevil could hide, and closed the mill as 
airtight as possible. I procured 100 soup plates and placed fifty 
on the first floor filled full of the bisulphide, and fifty on the 
second floor, as near their haunts as possible, and closed the 
doors until Monday morning, when presto! change, they were 
nearly all gone to the happy weevil hunting grounds. I saw a
