Every purchase of Chrysanthemums brings us an army of this pest, but I have always succeeded in getting rid of them. My method is to watch the plants carefully every day and wash them in strong soap-suds. Tobacco soap is best, but any good soap will do; taking care to allow none to escape from the dish of suds, and follow up this treatment without intermission as long as any remain. Various insect remedies are said to keep down all these pests of the greenhouse, but that is not at all satisfactory and calls for " eternal vigilance." When extermination is at all practicable it should be the result aimed at. If any one will inform me how I can get rid of Mealy bug at any reasonable cost, I shall consider it the most valua-piece of knowledge yet gained in greenhouse management. If they only attacked the tops of the plants I think I could clear them out, but I find them in the sand of the cutting-bench and in the pot. If I had a new greenhouse to build and no other very near it, I think I would not allow a single plant to go into it until it had gone through a thorough quarantine and an insect purgatory, and would, as far as possible, refuse admission to anything but cuttings known to be clear, and if it was necessary to introduce any plants would remove all soil and carefully wash all the roots as well as tops before admitting them.
