FUMIGATION WITH CARBON BISULPHID 28 1 



actually succeeded in shutting down our 100 h. p. en- 

 gine by so choking conveyors, elevators, etc. , with its 

 webs that the wheels simply could not turn. This is 

 an absolute fadl. 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, New 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
