It is important that the oil be added in small quantities at first, and also that the stirring be sufficient to keep the oil and soap in the form of an emulsion after each addition of oil. Thus at first about a pint of oil sliould be added to the soap, and the mixture stirred until no free oil appears. As the amount of oil is increased, it should always be stirred or mixed thoroughly before the next addition is made. After the required amount of oil has been added, and after free oil has ceased to appear on top of the soap, the water is slowly poured in, about a quart at a time. To determine whether the mixture will form a perfect emulsion, add a little of it to soft water, and if no oil floats, the mixture is perfect and may be used for spraying. The presence of floating oil indicates an imperfect mixture, and results from adding the oil too suddenly, or from insufficient stirring. This condition may be remedied by the addition of more soap, which is preferable to throwing away llie entire mixture. For spraying orange trees, use 1 gallon of Hit-slock mixture prepared as just described to 50 gallons of water; or use the entire amount to make 200 gallons of spray material. This dilution contains approximately 1 per cent of oil, which is the maximum strength required for whiteflies and the purple scale. For three-fourths of 1 per cent of oil, add 1 gallon of the stock mixture to 66 gallons of water; and to obtain one-half of 1 per cent, add 1 gallon of the stock mixture to 100 gallons of water. Many alterations may be made in the foregoing formula. The quantity of soap will depend largely upon the time consumed in adding the oil, and the amount of stirring accompanying this process. The amount of soap is lessened if the stirring is uniform, and if am...
