Very abundant in the East,particularly in thin clover fields and in gardens; rather rare in the West,where it is a comparatively recent introduction. Injury: A rank grower and a heavy seeder. The greatest injury isperhaps due to the frequency of the seeds in clover and grass seed, and thegreat difficulty in separating them. Remedy: This weed is easily destroyed by ordinary methods, and, likeall weeds, yields to a regular short rotation of crops. In clover grown forseed it should be hand-pulled as soon as the flowers show. Every care shouldbe taken to sow hipfh class clover seed free of the seeds of this Cockle. 34 Plate 12.
