ECONOMIC VALUE OF FUMIGATION 253

Allen, government fruit expert, who at the same time 
placed at my disposal a large amount of useful infor- 
mation for my guidance at the start. The first diffi- 
culty which presented itself was that of procuring 
tents—how many to get, what sizes, and where to get 
them at a reasonable cost. Firms in Sydney asked a 
price that was practically prohibitory. In my diffi- 
culty I applied to Mr. Walter Bevan, of Galston, who 
at this time was having his trees treated by this pro- 
cess, and he it was who put me in the way of getting 
them at a moderate figure. The least expensive 
method is to buy the material at some wholesale house 
and have it made up at home. For the purpose noth- 
ing could be better than ‘ circus-tent calico,’ both for 
lightness and durability. At present the wholesale 
price is 1s. 5%d. per yard of 6 feet wide. 
‘“‘In my opinion no grower should bother with 
tents, but have the material made into square sheets 
the sizes he requires. They are easier to make than 
tents, answer the same purpose exactly, and are much 
more readily placed over the trees. The number to 
get and the sizes will naturally depend on the trees 
the grower has. I got four tents and two sheets, each 
sheet being 40 x 4o feet, and with this number two 
men can do from 30 to 50 trees each day. I began 
fumigating about the end of January last, and instead 
of doing the work at night, which is generally accepted 
as the proper time, I did all mine by daylight. Orange 
trees badly infested with scale, I found, lost a large 
portion of their leaves, those with less scale a much 
smaller quantity. Having the cyanide broken up too
