256 FUMIGATION METHODS 
you a tent which will cover a well-grown ten-year-old 
orange tree, provided the tree is not more than 13 feet 
high. 
‘‘ What I should like to see the government do is 
to get together a large plant (say, twenty-five tents) 
and employ four men to manage it, and go round to 
various orchards in each district and fumigate them, 
charging the owner the cost of cyanide, etc., labor, 
and enough to allow for wear and tear in tents, and 
interest on their outlay for same, as I feel sure many 
orchard owners would be only too glad to have their 
orchards done, but they have not the capital to spare 
to get the necessary plant, as one wants a fair num- 
ber of tents to do the work quickly. I find myself 
and one man can manage fourteen tents comfortably. 
Your formula of one cyanide, one acid, and three water 
is not sufficient to work off the cyanide in forty-five 
minutes, so I use one, one-and-a-half of acid, and 
three. You are welcome to publish all of this if you 
think it of any use, and to say that I strongly urge 
growers to go in for fumigating, as there is nothing else 
to compare with it in efficiency and cheapness.”’
