Cyclopedia of American horticulture : comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches.

Square tower eiving more workine space for the nozzle men than the conical form barrel so as to make a dilute milk of lime but never allow it to be dense enough to be of a creamy thickness. 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 ferrocyanide of potassium (yellow prussiate of potash) continue to change from yellow to a brown color. When no change of color is shown, add another pail of milk of lime to make the necessary amount of lime a sure thing. A small excess of lime does no harm. The barrel can now be filled with water, and the Bordeaux mixture is ready for use. The preparation of ferrocyanide of potassium for this test may be explained. As bought at the drug store, it is a yellow crystal and is easily soluble in water. Ten cents' worth will do for a season's spraying of an average orchard. It should be a fnll saturation; that is, use only enough water to dissolve aU the crystals. The cork should be notched or a quill inserted so that the contents will come out in drops. A drop will give as reliable a test as a spoonful. The bottle should be marked "; Dip out a little of the Bordeaux mixture in a cup or saucer, and drop the ferrocyanide on it. So long as the drops turn yellow or brown on striking the mixture, the mixture has not received enough lime. Ammoniacal Copper Carbonate. Copper carbonate 5 ounces Ammonia (26° ^) 3 pints Water 45 gaUons Make a paste of the copper carbonate with a little water. Dilute the ammonia with 7 or 8 volumes of water. Add the paste to the dUuted ammonia and stir until dissolved.
