The Practical Counsellor for Fruit and Garden Culture, of Frankfort, Germany, recently offered a prize for the best method of destroying plant lice, for which 58 persons competed. The prize was awarded to the author of the following preparation: Qnassia wood 2 1/2 pounds, to be soaked overnight in 10 quarts of water and well boiled, then strained through a cloth, and placed, with 100 quarts of water in a petroleum barrel with 5 pounds of soft soap. The mixture is then ready for sprinkling on plants infested with lice. Leaves, even those of peach trees, will not be injured in the least by the solution, which can be kept covered in the barrel from spring to fall without deterioration. As soon as the lice appear the leaves should be sprinkled with the solution. If this is repeated several times, the pests will disappear.
