The same insect attacks the turnip, cauliflower, and probably other plants. A closely related species is very injurious to the radish. The presence of the insect most frequently becomes manifest upon the cauliflower about two weeks after the plants are set out, and is recognized by the plants ceasing to grow, and wilting or assuming a bluish appearance. Such plants should be at once removed, together with the earth immediately surrounding the root, and fresh plants which have been held in reserve set in their places. The only satisfactory remedies are preventive ones. The seed-bed should be composed of soil taken from the woods, or at least from some place where no cabbages or similar plants have been grown. But the most important precaution is to avoid growing the crop year after year upon the same ground, especially after the insect has made its appearance. The following remedy, given by Francis Brill, in his pamphlet on "Cauliflowers," is worthy of careful trial. Mr. Brill says: "The ravages of the root maggot have made the growing of early cauliflower, and even early cabbages in many sections, almost an impossibility, but there is a remedy, when the maggot has attacked the roots of the plants, which may be known by a tendency of the leaves to wilt and droop in the heat of the day, very much the same as when affected by club root. Dissolve Muriate of Potash (analyzing 45 per cent. actual potash) in water in the proportion of one tablespoonful to the gallon; or double the quantity of Kainit or common potash salts (13 per cent. actual potash). Apply this directly to the roots, about one gill to each plant, whether seemingly affected or not, for the maggot will have done much harm before the plant will show it, repeating the application as occasion may seem to require. In sections where these maggots have been prevalent it will be well to make a solution of half the above strength, and when the plants are nicely started apply in the same manner as a preventive. Care and judgment must be used not to overdo the matter, thereby killing the plants as well as the maggots. Experiment a little at first." H. A. March, of Washington, says: "The best thing that I have found for the maggot is a _poor_ grade of sulphur, sulphur before being purified, that _smells very strong_. Sprinkled over the plants it seems to drive the fly away." CABBAGE WORM (_Pieris rapæ_, Koch).--The imported cabbage worm, now known all over the country, is the most troublesome enemy which attacks either the cabbage or cauliflower, and the most difficult one with which to deal. It seldom wholly destroys the crop, and is generally a little less destructive after a few years than it is at first, being kept in check by its natural enemies. It never disappears, however, and its numbers cannot be materially diminished for any length of time by artificial means. Among the partial remedies in use are the following:
