FUMIGATION WITH CARBON BISULPHID 281 
actually succeeded in shutting down our roo h. p. en- 
gine by so choking conveyors, elevators, etc., with its 
webs that the wheels simply could not turn. ‘This is 
an absolute fact. Meanwhile I had written to Prof. 
W.G. Johnson, the expert, about the pest and sent 
him a sample of its work. When the mill was finally 
choked to a standstill I knew what to do. I first put 
six men at work taking spouts and elevator legs apart 
and cleaning them thoroughly, and when that was 
done I had them go for the machines. It took us just 
six days to get cleaned up. Under the Professor’s — 
advice I had provided ten gallons of carbon bisulphid 
and about 200 tin pie-plates. Saturday afternoon we 
closed and packed all the doors and windows, distrib- 
uted the plates throughout the mill, filled them with 
bisulphid, and ‘‘let her simmer ’’ until Monday morn- 
ing. Opening up the mill we found dead moths every- 
where.—L. C. SCHROEDER, ew York. 
Some insurance companies were a little uneasy lest 
they should suffer loss by fire originating from the 
use of carbon bisulphid in mills. The American 
Miller investigated this subject by sending letters of 
inquiry to all the important millers’ insurance com- 
panies in the United States and Canada, and did not 
learn of a single fire known to have been caused by 
the use of carbon bisulphid. The properties of the fluid 
have been fully described above, and millers have been 
warned to keep lights and fire away from the vapor, 
lest an explosion should occur. The fact that it has 
been used so long without fires being traceable to it 
gives strength to the opinion that millers, out of con- 
sideration for their own lives, have heeded the warning
