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. ' '
