churn the whole together for ten minutes, and dilute when used with 
ten times the amount of soft water. 
“ For combined wash that will destroy sucking and biting-mouthed 
insects, mix two pints of the concentrated paraffin emulsion with 
the arsenate of lead wash. 
“ You cannot combine Bordeaux mixture with Paris green and 
paraffin emulsion; you can combine it with Paris green alone. 
Nor can you mix Paris green and liver of sulphur, or Paris green 
and soft soap washes. 
“ Arsenate of lead you can mix with Bordeaux mixture, and 
paraffin emulsion and quassia washes ; thus you get a good wash, 
combined of a fungicide and the two chief insecticides. This may 
also have liver of sulphur added for Bed Spider and Mites, but it is 
not advisable to do so. 
“ Paranaph may, of course, be substituted for paraffin emulsion.” 
Mr. Town Smith writes that “ we have used Paris green with soft 
soap wash or paranaph with care — 2 ozs. Paris green, 40 gallons 
water and soft soap wash — without marked damage to the trees.” 
Mr. Cecil Hooper, of Swanley, on the other hand, writes that he 
has “ used soft soap and Paris green, and that he found the foliage 
burnt.” The mixture is certainly not good. 
Mr. Hooper also writes as follows : — “ I have also used Paris 
green and Bordeaux mixture ; but I find this mixture a good deal of 
trouble, but I believe it to be a good thing.” I do not think a good 
wash can possibly be made out of the two. 
Painting Fruit Trees. 
Mr. J. Le Feaver, of Stile Bridge, Marden, wrote asking for the 
best paints to use for fruit trees during the winter for destroying 
insects. 
The best mixtures to whitewash fruit trees with are the 
following : — 
1. Lime and water made into the consistency of a fine paint, and 
to every ten gallons of this add one pint of paraffin. 
2. Fine clay made into a thin paint. To every gallon add half a 
pound of liver of sulphur. 
3. But best of all is washing the trees with caustic alkali wash 
in winter. By so doing not only is healthy bark produced, but 
Mussel Scale, Woolly Aphis, Codling Maggot, Thrips, and many 
other pests are destroyed.
