“We opened the mill Monday morning and thoroughly venti- 
lated it before starting. We found that we had destroyed thou- 
sands, and in the reels and purifiers we had killed them all. In 
the course of a few days, however they began to show up in the 
cracks in the floors all over the mill, ami in dark corners. Two 
weeks later we repeated the dose or bisulfide in the same 
manner and obtained about the same results. In the meantime, 
however, we whitewashed the mill from top to bottom; that is, 
every place that could be covered, putting on a good heavy coat. 
We have not destroyed them all by any means: but we have re- 
duced their forces to a very small number. Eternal vigilance 
is the order of the day. 
“We are still fighting them. Our plan is to keep a stock of 
bisulfide on hand outside of the main building, as we do not 
think it advisable to store it in the mill on account of its inflam- 
mable nature. Wherever we find a place infested by the weevil 
we use it freely, taking care to do it when the mill is shut down 
and closed up tight. We find the best results from the use of 
bisulfide of carbon can be obtained by spraying it on the floors 
and infested places. We think when placed in plates it does 
not evaporate quick enough to produce the death atmosphere 
required. Before closing let us return our sincere thanks to 
you for the interest you have taken in the matter, and assure 
you that we appreciate your valuable advice.” 
The "American Miller,” for July, 1905, contains another 
interesting and valuable communication on this subject, from 
Mr. H. J. Laurie, of Norwalk, Ohio, and 1 quote it here in full: 
“As the season is now upon us when a large majority of the 
iron spouts. That was the end of our trouble for months, and I 
flouring mills of the country are being troubled with insects of 
various kinds, such as weevils, worms, moths, etc., I thought it 
might not be out of place to give our experience here with 
bisulfide of carbon, which we have been using for several 
seasons with very satisfactory results. 
“I have reason to believe that a number of millers have 
used this remedy with very indifferent results, owing, in my 
opinion, to the manner in which it was applied. In the first 
place, the mill should be thoroughly swept (as every mill should 
be daily), and if there are any broken panes of glass in the 
windows they should be replaced, the object being to make the 
mill tight as possible. Then have a number of shallow tin 
pans, say, about fifty to every 100 pounds of the compound 
used. Begin at the bottom of the mill, and place the pans 
where the insects are the thickest. It is best for two to go 
together, one placing the pans, the other filling them, using a 
watering can or something of the kind having a spout. 
“I apply it to the bolting reel and flour garners as follows: 
I get ready, beforehand, a number of medium sized bunches of 
cotton-waste, two for each reel, with a string attached to each. 
I dip these bunches into the bucket of compound, pressing out 
with a paddle so they will not drip too much; then throw them 
under the reel and down the conveyor, leaving the string on 
the outside so they can be recovered, then close the doors of 
the bolting chest tightly. I suspend one or two bunches in 
like manner in the flour garners and screening bins. In applying 
it to the wheat bins we level off the grain and place the pans 
on it filled with the liquid. By applying it in this way to wheat 
bins and taking proper care to have the bins emptied and swept
