By fumigation it is to be understood treatment by hydrocyanic gas. This 
treatment shall be done as follows: All nursery stock to be treated should De 
placed in an air-tight tent or box. For every one hundred cubic feet of space in 
box or tent, take one ounce, avoirdupois weight, and fused potassium cyanide, 
ninety-eight per cent strength, preferably in lumps about the size of a walnut; 
one and one-half ounces commercial sulphuric acid, best grade, and two and one- 
fourth fluid ounces of water. First: Piace the water in a three-gallon vessel 
(which may be glazed earthenware); to this add the acid and finally the 
potassium cyanide. (The cyanide would be better enclosed in a small paper bag 
in which a hole is torn.) Immediately close the doors or openings, taking all pre- 
cautions against inhaling the gas, as it is one of the most violent poisons known. 
After leaving box or tent closed for forty minutes open all doors and allow at 
least one hour for thorough ventilation before attempting to remove stock. No 
injury is caused to nursery stock if the gas is left in for more than forty minutes.
