42 DESTRUCTIVE INSECTS OF VICTORIA: 



foliage (just what is wanted), and if properly applied will 

 answer for most purposes. This soap is referred to in 

 another part of the book. 



In perusing the report of the United States Entomo- 

 logist for the year 1886, which Professor Riley has been 

 kind enough to send to me, a most complete and exhaus- 

 tive series of reports are given concerning experiments 

 which have been made by the clever field agents working 

 under the direction of Professor Riley, and although the 

 information thus recorded is practically invaluable to 

 growers and economic entomologists, for want of space 

 it cannot well be reproduced in this little volume. We 

 can, however, gather from the accounts of tlje experi- 

 ments made in the United States that the two best 

 remedies against this pest are (gas-tents excepted) un- 

 doubtedly Kerosene Emulsion and the Eesin Compound. 

 The above information, which would alone fill a small 

 volume, should be read by every one having access to 

 these eminently useful, plain, and practical reports. 



When spraying trees against this pest, also against 

 other coccids, it should be remarked that any material 

 must be used hot. In kerosene and other resin com- 

 pounds we have cheap, valuable, and effectual remedies 

 for most insect pests. Specifics against insect attacks to 

 be of use for large growers must be cheap and easy of 

 application, otherwise their use cannot become general. 



We should carefully and jealously protect our native 

 insectivorous birds, although birds do not seem to relish 

 the coccidae. Endeavour by all the means in our power 

 to investigate and press into our service all natural para- 

 sites and enemies to our pests, but while doing this we 

 should never relax our efforts in the spraying line. The 

 time has now arrived when to be successful in fighting 

 insect pests, and manage an orchard on modern prin- 

 ciples, a good spraying gear ought to be part of the 

 machinery in every well-ordered farm and on every well- 

 managed orchard or vineyard throughout the colony. 



In Victoria I hope we may not have much to fear from 

 the attacks of the cottony-cushion scale, as so far it has
