FUMIGATION AND CHEMICALS. 
The laws of many states require the fumigation of nursery stock 
with Hydrocyanic acid gas. The necessary equipment consists of an 
air tight chamber (box or house) a glazed earthenware vessel, a glass 
measure graduated to ounces (a plain tumbler, mark the sides with a 
file) and a set of accurate scales, the necessary chemicals are Cyanide 
of Potash (98 percent.) and Sulphuric Acid (specific gravity 1.83.)* Care 
should be taken to secure the 98 per cent. Cyanide otherwise an insuffi- 
cient amount of gas would be generated and the fumigation prove 
ineffective. (“Commercial” Cyanide contains an average of 26.45 per 
cent. Cyanide of Potash.) Cyanide of Potash must be kept in an air 
tight package and so packed will keep indefinitely, it isa deadly poison 
and should not be left where it will fall into the hands of children or 
careless persons and should never be handled by a person having open 
sores, cuts or bruisesupon his hands. The gasis colorless and if inhaled 
in quantity is fatal, smaller amounts induce headache or dizziness 
The best commercial grade of Sulphuric Acid should be procured. 
This acid should be kept in a glass or earthenware vessel tightly 
stopped with a glass or lead stopper. 
The chief requisite for a fumigation house is that it should be air 
tight or gas proof. 
The standard formula for fumigating each 100 cubic feet of space 
contained in the fumigating house is as follows : 
1 ounce Cyanide of Potash (98 per cent.) 
2 fluid ounces Sulphuric Acid. 
4 fluid ounces of Water. 
The glazed earthenware vessel should be somewhat larger than is 
necessary to hold the chemicals, a one or two gallon jar is perhaps the 
best container. 
Fumigating. The trees, as dug and brought from the field should 
be placed in t lie fumigating house, care being taken to see that they 
are free from any considerable quantities of mud or dirt, the trees 
should not be fumigated when they are wet as it has been shown that 
in this condition they are likely to be injured by the gas. When the 
compartment is full of stock, close all openings except the door, place 
the jar on the floor near the middle of the room, pour in the required 
amount of Water and then slowly pour in the acid. The Cyanide pre- 
viously weighed and enclosed in a tight paper bag is now dropped into 
the jar and the operator leaves immediately and closes the doer tight. 
The steps in this operation SIIOUIJ) NEVER BP) VARIP)I). If water 
is poured into the acid a violent action takes place and may be the 
cause of injury to the operator, linclosing the cyanide in a paper bag 
makes it convenient and .safe to handle and retards the generation of 
the gas for a moment after being dropped, thus allowing time to leave 
the room and close the door securely. 
Keep the room closed for forty minutes, at the end of which time 
the door and window should be thrown open, care being taken to avoid 
the outward rush of gas. After fifteen minutes of airing the room may 
be safely entered ana the stock removed, being now ready for packing or 
heeling in. After fumigation the contents oi the jar should be buried.
