BARBLES, or BARBS, in farriery, the knots or superfluous flesh that grow up in the channels of a horse's mouth; that is, in the intervals that separate the bars, and lie under the tongue. These, which are also called barbs, obtain in black cattle as well as horses, and obstruct their eating. For the cure, they cast the beast, take out his tongue, and clip off the barbles with a pair of scissars, or cut them with a sharp knife; others choose to burn them off with a hot iron.
