When the caterpillars are seen, a dusting of caustic lime, soot, or salt, is a good remedy; and hand-picking a sure, but very troublesome one.—(M. D.). Shaking the infested plants or leaves (as may easily be done by a light blow with a small bough or birch-besom) so as to make the caterpillars fall off, and then trampling on them, is a good remedy. Drenchings of liquid manure, or of water alone thrown over the plants, would be serviceable, from the circumstance of sudden wet being prejudicial to the caterpillars; and also—as from their great size they consume the leaves very rapidly— it is very important to stimulate the growth of the attacked plants as much as possible. Should a serious attack occur to field crops, many of the methods of remedy given in detail for caterpillars of moths, or of Sawfly on Turnips, would be applicable. CABBAGE. Cabbage Aphis (Cabbage Green Fly). AjMs hrassicca, 1 and 2, male Aphis; H and 4, female (nat. size, and magnitiod). Cabbage Aphis.—These "Green Flies" may be found on the Cabbage in great numbers during the summer, clustered under the outer leaves, and also in the folds or on the upper side of the inner leaves; and some may be found remaining even as late as the end of November. They do muoh harm by inserting their suckers in the plants and drawing away the juices; and also causing a deformed and diseased growth. A.:.
