it was suspected that these worms came from the moths which had been 
seen in the mill. In July the bolting cloths, riger and some 
other parts of the machinery, were carefully cleaned and washed. In 
about four days after starting again, the bolts, ieit, etc., were 
found to be in a worse state than ever, full of webs, moths, and worms. 
The mill was shut down and a more thorough cleansing set about. 
But it was found that every crack and crevice was alive, and as the 
character of the moth was entirely new, an application was made to 
the Government for assistance. A number of visits were made to the 
infected mill by the authorities, and an order in council was passed by 
the Government ordering the Provincial Board of Health for Ontario 
to suppress the pest. The machinery was taken down and thoroughly 
steamed ; the building was swept and subjected to the fumes of burn- 
ing sulphur; the loose wooden parts, such as elevator spouts, etc., 
were burned, and paper bags, boxes, and any goods suspected of being 
infected, were similarly disposed of. Even the mill-stones and iron 
rollers were thoroughly steamed by placing them in a tight box with a 
pipe from the boiler. After about two months’ loss of time, and a 
large outlay for new machinery, stock, etc., the mill was pronounced 
free from infection and ready to go to work again. As may be sup- 
posed, its proprietors have taken’such precautions as will prevent the 
pest gaining a footing should it again make its appearance. They 
have provided a steam stand-pipe, with hose leading to each flat of 
the mill, so that live steam can be turned on sufficient to kill anything. 
The importance of dealing promptly with the Flour Moth whenever 
and wherever it appears, has led the Ontario Government to issue a 
bulletin, in which the following precautions are suggested to prevent 
its introduction, and means of eradication pointed out should it ap- 
pear: (1) no milled goods, such as Italian semolina, Indian cassava, 
and Brazilian tapioca, should be allowed to enter the country, espec- 
ially from Mediterranean ports, without being quarantined in a warm 
place for a number of months, so as to give time for the ova, if 
present, to hatch; (2) all s used for transporting flour, meal, or 
grain should be prevented from entering the country till they have 
been thoroughly boiled or steamed so as to kill any germs; (3) mil- 
lers, exporters and importers of flour or grain should familiarize them- 
selves with the appearance and habits of the moth at its various stages, 
and take measures to destroy individual specimens before they have 
time to multiply. Should the pest have made its appearance the fol- 
lowing measures are recommended : (1) Destroy the moths by closing 
all apertures and burning sulphur night after night in all parts of the
