churn the whole together for ten minutes, am] dilute when used with 

 ten times the amount of soft water. 



" For coml )ined wasli that will destroy sucking and biting-mouthed 

 insects, mix two pints of the concentrated paraffin emulsion with 

 the arsenate of lead wash. 



" You cannot coml;)ine 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 Eed Spider and Mites, Ijut it is 

 not advisable to do so. 



" I'aranaph may, of course, be substituted for paraffin emulsion." 



Mr. Towai 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 Maites 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.
