and even liquid starch properly applied, can do this ; but to clean 
the leaf temporarily, without reaching the seat of the disease, is 
simply to provide a fresh surface for the scale insects to act 
upon. 
The formula for Resin Wash, as given in Webber's pamphlet, 
already referred to, is as follows :— 
Resin ... ... 20 lbs. 
Caustic soda (98 °/ o ) ... 4 „ 
Fish oil (crude) ... 3 pints 
Water ... ... 15 gallons. 
Boil about 13 gallons, and add the three constituents, boiling 
until the resin is dissolved, which will he in a few minutes. 
Add 2 gallons more of hot water, and this becomes a stock 
solution. 
When required for use thoroughly stir it, in order to uni¬ 
formly mix the precipitate at the bottom, and take 1 part 
of the stock solution to 9 parts of water. If required for 
immediate use, the hot solution could be poured directly 
into the spray tank, and diluted with 9 times as much 
water, or 135 gallons, in order to bring it up to 150 
gallons. 
In the October number (1898) of the Agricultural Gazette of 
New South Wales a slightly modified formula is given : — 
Resin ... ... 16 lbs. 
Caustic soda... ... 6 „ 
Fish oil ... ... 3 pints. 
Boil 10 gallons of water, and add the above ; keeping it 
boiling and stirred till the resin is dissolved. Add hot 
water, a little occasionally, until the whole is made up to 
20 gallons. Dilute in the proportion of 4 gallons of hot 
water to 1 gallon of the hot solution, thus making it 100. 
It is recommended to keep the solution as hot as the hose 
will stand. 
Removal of “Sooty Mould' 1 from the fruit .—In America 
there are several methods of removing the fungus from the fruit, 
when it seriously affects its market value, but these are only 
makeshifts. It never has the same appearance and quality as 
naturally clean fruit, and the process is tedious and costly. 
There are what may be called the dry and wet methods. In the 
dry method a revolving barrel is used, the inside of which is care¬ 
fully cushioned to prevent the oranges being bruised. Dry sifted 
sawdust, principally fine, is placed in this, and the fruit is rolled 
for several minutes, then the handling afterwards removes any 
trace of sawdust. Of course the sawdust has to he frequently 
changed, as it soon becomes foul. The wet method consists in
