the flour and cause the death of the pests. The barrel should 

 be kept closed for two days, and if the beetles have been very 

 numerous the treatment should be repeated. The flour is not 

 harmed by exposure to the fumes. 



In order to disinfect a store or mill, the building should be 

 made as airtight as possible, and bisulphide of carbon, in the 

 proportion of one pint for every 1,000 feet of cubic space, 

 should be placed in soup plates or similar shallow vessels. 



The operators must not for any length of time continue to 

 breathe the fumes of bisulphide of carbon, nor must any light 

 (not even the lit end of a cigar or a lighted pipe) be brought 

 near. Owing to the heavy character of the vapour it will flow 

 down from one level to another, and thus although being used 

 away from fire it may flow down and come into contact with it 

 with serious results. Hence the work of eradication should 

 be started during the day time, so that no artificial light is 

 required. As the fumes are heavier than air, if the building 

 being fumigated consists of more than one storey the work 

 should be begun on the lowest and proceed upwards. The mill 

 or store should then be locked and kept locked for some days 

 (Saturday to Monday) when the place can be ventilated ; the 

 disagreeable odour soon disappearing. An additional useful 

 measure would be to spray the bisulphide into crevices or over 

 machines likely to harbour the pests, and plugs of cotton wool 

 steeped in the bisulphide of carbon might be pressed into spouts 

 and crevices.
