IS Excellency the Governor, with the advice of the Executive Council, and in pursuant? 
of the provisions of “The Diseases in Plants Act of 1896,” has been pleased to m 
the following further Regulations. | 
’ oe J. V. CHATAWAY. | 
THE FUMIGATION OF FRUIT FOR EXPORT. 
1, Any one who wishes to erect a chamber or building for the fumigating of fruit is requested 
to give notice to the Under Secretary for Agriculture, who will take steps to see that the chambe! 
or building is properly constructed. > 
2. When it is required to fumigate fruit for export, twenty-four hours’ notice must be giv 
to the said Under Secretary or such other officer as may be duly authorised to accept such notice, 
3. The operation of fumigating must be conducted under the control of an officer authors 
by the Minister for Agriculture. f at 
4. The fumigating chamber may be made of any convenient size or material, the essential pol! 
being that it shall be capable of being closed absolutely airtight, and provided with a flue-p} 
in the roof which can be opened or closed to allow of the escape of the gas after fumigation. + 
flue must be provided with a box or chamber to contain caustic soda or potash to destroy the gas 
The fumigating chamber must be provided with a shutter or sliding panel in the lower port! 
of the door or wall. ‘ | 
Door, flue, and shutter must all be made to close absolutely airtight. 
DIRECTIONS FOR FUMIGATING WITH Hyprocyanic Acip Gas. 
Proportions of Ingredients.—For every 150 cubic feet of room take 1 ounce of cyanide of potas 
sium, 5 fluid ounces sulphuric acid, 10 fluid-ounces water. ahs 
Having placed the fruit to be fumigated in the chamber, see that the flue and the shutter in t 
door or lower part of all are properly closed. io 
The acid is then to be diluted in the following manner :—The whole of the water is placed 
a shallow china or glazed earthenware vessel, such as an ordinary wash-hand basin. 
vessels are inadvisable unless they are leaden ones.) The sulphuric acid is next poured on to ¥ 4 
water in a thin stream, stirring the while with a stick. Do not mix by adding the water to the a0 
The basin containing the acid thus diluted (which should be allowed to cool) is now plac 
the fumigating chamber, and the cyanide of potassium is emptied into it. 
The gas is given off with great violence, and the door should be immediately closed. te 
The whole is now to be left to itself for one hour. At the end of this time the shutters in 
flue and in the door are opened, and the draught produced drives the gas out of the chamber. — ald 
the end of half an hour the door is thrown open, and if the draught has been effective there shove 
be Ey any trace of hydrocyanic gas recognisable. The chamber may be left in this conditl ‘dl 
for another ten minutes or a quarter of an hour. The fruit is now to be moved and allowed” 
remain in a well ventilated place, preferably out of doors, for another half an hour, Samples”: 
fruit will be examined from time to time by the entomologist. ; i tel 
Caution.—As hydrocyanic acid gas is most deadly in its effects on animal life, the great” 
care must be taken in its use.
