Obs. This vile intruder is becoming a great nuisance in our country. In some districts the careless, slovenly farmers have permitted it to get almost exclusive possession of their pasture fields, - rendering them quite white when the plant is in bloom. Cows will occasionally crop a portion of the weed in our pastures, - and I have heard it alleged that it contributes to the' mating of good butter: but my own observations induce me to regard it as utterly worthless. It fa propagated rapidly, and is, moreover, exceedingly difficult to get rid of, when once fully established; so that one negligent sloven may be the source of a grievous annoyance to a whole community. I have understood that annual ploughing and cropping for a few years, is the most effectual remedy for the evil; but then the fence-rows and neighboring fields must be well watched, to prevent the formation and introduction of fresh seed. The Corn Marigold (Chrysanthemum segetum, L., a kindred plant) - .which is said to be such a pest to the agriculture of Europe - does not appear to have found its way, as yet, to the United States.
