Dissolve the powdered blue-stone in water ; 

 separately slake the quicklime in water; mix 

 the two; make up to four gallons and pour 

 into the sprayer through the strainer. A 

 knife blade put into the solution should not 

 acquire a brown deposit of copper ; if it does, 

 add more lime. 



Crude oil emulsion is prepared by dissolving 

 four ounces of the emulsion in a Kerosine tin- 

 ful of water. 



Gondal fluid is another remedy for the white 

 ant. It can be purchased ready-made from 

 Waldie & Co. ; but it can also be made at home. 

 Take two parts each of asafoetida, bazar 

 aloes and castor cake, and one part of " Dek- 

 amali " gum ; pound and mix thoroughly ; then 

 keep in water for about a fortnight ; and when 

 thoroughly decomposed into a thickened com- 

 pound, add water till the mixture is the 

 consistency of paint. It is advisable to add 

 some colouring matter, such as red ochre, so 

 that it can easily be seen what trees have been 

 treated. The materials can be purchased in 

 the bazar and the cost should not be much. 

 The fluid should be applied in a continuous 

 band round the trunk of the tree to a height 

 of about two feet from the ground. This 

 part of the trunk must be brushed free of ants 

 and quite cleaned of all mud encrustations. 

 Care must be taken to see that the fluid pene- 

 trates into all the crevices of the bark.
