KEROSENE EMULSION.
Paraffin, made into an emulsion *svill. soft soap, has long b*en used as an insecticide, but one drawback to its use is the tendency of the paraffin to separate fro mthe emulsion. Mr Macoun, horticulturist to the Canadian Department of Agriculture, finds that when flour is substituted for soft soap the emulsion obtained is finer and more permi lont. By mixing one gallon of paraffin, 3ilb. ot flour (the poorest quality serves), and mixture vigorously for five minutes, an emulsion is obtained which remains good for 14 hours. If it is not required to kesp _ the emulsion so long, half the quantity of flour suffices. It is best to add the flour to the paraffin, and then to pour in about 4 gallons of water, to beat the mixture vigorously until the emulsion is obtained, and then to make up the rest of the water (5 gallons).
