If in the latter condition, lumps of lime will clog the spray noz- zle. Continue to add to the mixture this milk of lime so long as drops of ferroeyanide of potassium (yellow prussiate of potash) continue to clnmgefrom yellow to a brown color. When no change of color is shown, add another pail of milk of lime to make tlie necessary, amount of lime a sure thing. A small excess of lime does no harm. The barrel can now be tilled with water, and the Bordeaux mixture is ready for use. The preparation of ferroeyanide of potassium for this test may lie explained. As bouglit at the di-ug store, it is a yellow crj'Stal and is easily soluble in water. Ten cents' worth will do for a season's spraying of an average orchard. It should be a full saturation; that is, use only enough water to dissolve all the crystals. TVie cork should be notched or a quill inserted so that the contents will come out in drops. A drop will give as relialile a test as a sjioonful. The bottle should be marked "; Dip out a little of the Bordeaux mixture in a ciipor saucer, and drop the fcrri>i-y;inide on it. So long as the drops turn yellow or brown on striking the mixture, the mixture b;is not received enougli lime. AMMONIACAL COPPEH <.'A1!I'.0NATE.
