ECONOMIC VALUE OF FUMIGATION PAO 
Lieutenant-Governor in Council, in accordance with 
the provisions of the San José Scale Amendment Act, 
passed April 1, 1899: 
rt. Fumigation must be carried on in a box, room, com- 
partment, or house, suitable for the purpose, which must be 
air-tight and capable of rapid ventilation. The owner or 
proprietor will notify the Minister as soon as preparation for 
fumigation is complete. The Minister will thereupon order

is to be thoroughly ventilated for fifteen minutes at least. 
6. No person is to be allowed to enter the fumigating
