action. Afterwards Dr. Bryce and Prof. Fletcher came together, and finally the 
whole matter was left in charge of Dr. Bryce and the Provincial Board of Health.” 
Measures of purification by steaming and fumigation:— 
“In the meantime we took down our machinery, and subjected it to steaming. 
Every part was thoroughly steamed. The mill was swept down, and subjected to 
sulphur-fumes. The walls, ceilings, &c., were cleaned, and elevator-spouts and 
loose wooden work burnt up. Paper bags and hundreds of dollars worth of goods 
were burnt in the furnace, while the other bags, elevator-belts, and cups were boiled 
for hours in a cauldron of water. The machines and all parts that were not 
destroyed were then burnt by means of a kerosene torch, which flamed and smoked 
through and around every part of them, until we considered we had everything clean 
and ready for putting together again.” 
More stringent measures enforced by an Order in Council approved 
by His Honour the Lieutenant-Governor :— 
“But on September 19th the Local Government passed an Order in Council 
compelling us to take more stringent steps, or rather ordering the Provincial Board 
of Health to take immediate steps for the suppression of the pest. This Act was 
approved of by His Honour the Lieutenant-Governor, who signed the Order in 
Council, and on September 20th we received an order from Dr. Bryce which stated 
that before placing our machinery in position we should subject it to a thorough 
disinfecting process in a strong room so arranged that steam under pressure might 
be drawn or driven into it.” 
Further measures to allow application of steam pressure to the 
machinery:— 
“ In compliance with this order, we at once constructed a tight steam-box, 
6 ft. wide, 6 ft. high, and 12 ft. long, and attached a steam-pipe to it from the 
boiler. In this box we put every machine, and even our mill-stones and iron 
rollers. This process was very expensive, and took up considerable time, as we 
were over a week at the process, and were delayed in the placing of our machinery. 
The Board of Health visited us in a body during the time this process was going on, 
and pronounced it a success. This was all done not only in our own interests, as 
was pointed out in the letter of September 20th from Dr. Bryce, but in the interests 
of the public health and commerce of the country. 
“ Having now got to the position which enables us to go to work again, after 
two months’ loss of time, and the loss of machinery, fixtures, stock, and expense, 
we have arranged for remedial measures to prevent the reappearance or destruction 
of the pest, should we ever be again attacked.”* 
(In a letter written to myself from tlie owners of tlie infested 
Canadian Steam Mills on Sept. 21st, 1889, tlie loss up to that date 
was stated to be about £1000.—E. A. O.) 
Returning now to the consideration of the pest in this country, 
I am aware of it being still present, and that in one instance it is 
being kept in check by frequent fumigation, of which I believe sulphur
