Dear Sir : — As I wrote you some time ago, my elevator was badly 
infested with weevil and also full of rats. I sent to you for fifty 
pounds of Bisulfide and used it according to your directions. I 
had ct the time about twenty-five hundred to three thousand bushels 
ol wheat in the house; this was last fall some time. I am now milling 
this wheat, and if there is any sign of weevil or rats, neither I nor any- 
one e'se can find them. I simply poured the,Bisulfide in the cor- 
ners of the bin, about one quart at a place, making a gallon to about 
one thousand bushels. The top of the wheat was about twenty to 
thirty feet above the ground floor, and the stuff must have gone 
down and cleaned out the rats for they are gone, fad this is a ratty 
neighborhood. E. W. Kruse. 
IT CLEARED THE MICE OUT OF OUR FLOUR HOUSE. 
MT. Carmel, ILLS., May 4, 1893. 
Edward R. Taylor : 
Dear Sir: — Enclosed find five dollars, amount of y-our bill. That 
is the stuff. It cleaned the mice out of our flour house. We simply 
opened the can and let it set in the house and it killed all young 
mice and drove the old ones away. Send us another can same size 
as last. Yours respectfully, The J. M. Shirk Co. 
In subsequent letters they say: "There is about one-third of 
the Bisulfide left in the can and by shaking it up once a day it seems 
to have the desired effect. We only used it in our flour houses but 
intend to use second can in mill , which is full of mill insects. 
We never had any fear of fire from the carbon, but of course 
used good common sense and cautioned all our men when they 
opened the flour house. There are no insects or worms of any kind 
in our flour house and we think it was your stuff that keeps them 
out. We move the can from one place to another every- day or so. 
You may use our letter as every miller and farmer should have 
a stock of it on hand. It certainly is great stuff. 
Yours respectfully, The J. M. Shirk Co. 
I do not advise the use of less than 100 pounds even for a mod- 
erately small mill. If too little is used, the goods and the work are 
lost, and relief not obtained ; if more than is necessary is used, the 
excess only is lost and the work done. Spraying is not advisable, 
as the bulk of the liquid is absorbed into the wood and is given out 
so slowly that it does not produce a death atmosphere. Do not use 
old fruit cans, they are too deep and the vapor cannot get out of 
them quick enough.
