Opinions of orchardists on fumigation in New South 

 Wales. Bevan Brothers, of Galston, write W. J. 

 Allen, the government expert, as follows: " We have 

 fumigated some 1,500 trees since this time (July) last 

 year, and the results have been very satisfactory. 

 Without doubt nearly every scale has been killed, the 

 trees are healthy, and the fruit clean. We formerly 

 sprayed from three to four times a year, tried several 

 preparations, and never got thorough satisfaction out

 on trees that have been fumigated, but, as far as we

 where the dose of acid has not been quite sufficient to

1 ' Several of our neighbors having seen the results 

 on our trees have had tents made, and set to work 

 cyaniding. This is surely the best proof of its value. 

 You are aware that we use a cheap tent made of calico, 

 costing wholesale about is. $d. per yard, double width. 

 So far this has answered admirably. Tents 10 feet in 

 diameter by 12 high cost from 305. to 355. This re- 

 duction in the cost of the tent really made fumigation

 same report : "I was prompted to enter upon what 

 seemed at first rather an arduous undertaking, viz., 

 the fumigation of my citrus trees for the destruction of
