208 FUMIGATION METHODS 
different sizes: Tents 15 feet high, 24 feet in circum- 
ference, require 16 yards of sail-cloth 6 feet wide, 
which, at 1s. 3d. per yard, will cost 41; tents 18 feet 
high, 36 feet in circumference, require 30 yards of sail- 
cloth 6 feet wide, which, at 1s. 3d. per yard, will cost 
LI 17s (6d. 
He says these are two of the most useful large- 
sized tents for general use. The former is quite large 
enough to cover trees 10 feet high and 8 feet in diam- 
eter, while the latter is large enough to cover trees 13 
feet high and ro to 12 feet in diameter. If larger trees 
are to be fumigated it is best to have octagonal sheets, 
sizes either 41 x 41 or 50x50. A sheet is always 
much easier to put over the tree than a tent where 
large trees are being handled. ‘The price of making 
the tents is not given, as any person having a sewing- 
machine can sew them together. ‘To make the former 
tent the material is cut in two. Find the center of 
each length, and from this point measure back 3 feet 
on opposite sides, draw a line diagonally across from 
one point to the other, and cut as marked. After cut- 
ting the two pieces can be sewn together. For the 
large-sized tent, the 30 yards must be cut in three 
pieces of 10 yards each, which should be cut again in 
an exactly similar manner to the smaller-sized tent 
and sewn together. Great care must always be taken 
to keep the tents perfectly air-tight. 
Good results—The outcome was very gratifying, 
and Mr. Allen says: ‘‘I feel quite safe in saying that 
by the autumn of rgo1 there will be over a thousand 
tents in use in New South Wales, with the result that 
there will be more clean and better fruit for export
