CHARLOCK, the English name of the RAPHANUS. It is a very troublesome weed among corn, being more frequent than almost any other. There are two principal kinds of it: the one with a yellow flower, the other with a white. Some fields are particularly subject to be overrun with it, especially those which have been manured with cow-dung alone, that being a manure very favourable to the growth of it. The farmers in some places are so sensible of this, that they always mix horse-dung with their cow-dung, when they use it for arable land. When barley, as is often the case, is infested with this weed to such a degree as to endanger the crop, it is a very good method to mow down the charlock in May, when it is in flower, cutting it so low as just to take off the tops of the leaves of barley with it: by this means the barley will get up above the weed: and people have got four quarters of grain from an acre of such land as would have scarce yielded any thing without this expedient. Where any land is particularly subject to this weed, the best method is to sow it with grass seed, and make a pasture of it; for then the plant will not be troublesome, it never growing where there is a coat of grass upon the ground.
