"Vetch, Fetch, Fitch, and Tare are terms variously used to indicate the fodder plant. This genus consists of about 100 species of climbing or diffuse herbs, distributed through temperate regions of the Northern Hemisphere and South America. It is one of the best fodder plants, but is only of one or two years' duration; it is important also for green manure, and as a companion crop with clovers. The practice of sowing it along with oats or barley is strongly recommended, insuring a greater bulk of produce, and preventing the crop from massing and rotting in wet weather."—(Charles Leonard-Stuart, 1911)
