CONCISE 
Directions for Using Ruma 
to Kill Insects In Mills. 
Use not less than 100 lbs. for a two story 30x40 foot struc- 
ture. Double the amount if badly infested. Increase the 
amount in the same proportion for larger structures. Open 
buildings require much more than tight ones. 
Clean the mill, have as little flour, feed, etc., in mill, convey- 
ors, machines, etc., ns possible. Open the doors of bolts, place 
a small shelf up in the flour packer, flour bins, etc.; borrow fifty 
soup plates from your merchant for each 50 pounds to be used 
(can be returned unharmed); (-do not use deep dishes — the 
evaporation is too slow); go through the mill and select places 
to put them. Place them high up when practicable, as the 
vapor is 2(4 times heavier than air and descends, and the vapor, 
not the liquid, does the work, but it must be thick enough for 
the evaporation from the numerous plates to produce a death 
atmosphere. Commence at the bottom floor and work up. Place 
plates above the bolts, etc. One person can fill and two place 
them. Take bunches of cotton waste of about % pound weight, 
saturate and place in top of conveyors, machines, etc. Be expe- 
ditious about the work, keep the liquid down and heads up, to 
avoid breathing the vapor unnecessarily. You need not be afraid 
of it, simply avoid breathing it. Set a saucer or shallow vessel, 
with a little in, near cracks and infested corners. See that all 
windows and doors are shut. For a grain bln, say 10x10x10, 
pour two pounds in four places near the four corners. Do the 
work Saturday afternoon by daylight. Absolutely have no 
Lights or Fire of any kind about. Close the mill and leave the 
bugs to their destruction until Monday morning. Then open 
doors and windows and thoroughly ventilate before going to 
work. 
I would emphasize the use of saturated cotton waste 
wherever practicable, as a very effective method of application. 
Spraying with sprinkling pots in corners, cracks and in- 
fested places is a most effective way, but you must be expedi- 
tious. 
For grain pour directly into the mass in several places, 
allowing about 1>4 gallons — 15 pounds — to each one thousand 
bushels. Cover closely to confine the fumes. 
(When not in use keep drums tightly sealed. Use haft 
soap on plug to seal It.)

Enclosed find draft for |6. Your Fuma Is all right; it does 
the work. I shall recommend it to our farmers; that is the place 
we get the weevil from. The next time I shall order 10 gallons. 
1 think it will fix mice and everything else.
