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 1 3 

 feet high and 10 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 50 x 50. 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 1901 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
