mixture thoroughly stirred. After the lye has been added, add 
4 more gallons of hot water and allow the whole mass to boil 
until the mixture will unite with cold water, making a clear, 
amber colored liquid. When through boiling if there is not five 
gallons of the mixture add water enough to make that quantity.

To 1 part of the resin mixture add 16 parts of water and 
3* parts milk-of-lime’ or whitewash, after which add Paris 
green, or other arsenites, at the rate of 1 pond to avery 30 
gallons of the resin lime mixture. Resin lime mixture should 
only be prepared as used. If allowed to stand any length of time 
it will settle. The resin mixture is in reality a liquid soap, and 
when milk of lime is added to the diluted resin mixture the lime 
flocculates, or forms a hard soap of the saponified resin, which 
floats in the water. When Paris green is added the particles of 
the latter adhere to the floceulated resin and the mixture remains 
suspended in the water nearly as well as does Bordeaux mixture. 
If the milk-of-lime is added to the undiluted resin mixture a. avy 
precipitate is formed. This not only settles rapidly, but it also 
gums up the valves and plunger of the pump and clogs the nozzles 
of the spraying outfit. 

3 If the mixture is added to cold water before all the resin has been sponified 
it will form a stringy mass in the water. 
4In previous report it was recommended that 4 gallons of milk-of-lime 
be used. This quantity of lime flocculates nearly all the resin soap in the 
mixture. It has been found best to have an excess of the resin mixture, hence 
less milk-of-lime should be used. : 
5 Milk-of-lime is made by slaking a quantity of stone lime of the best a 
and adding enough water to make a thin whitewash.
