"The recent development of crimson-clover seed strippers to gather seed for reseeding local areas makes practicable a much wider utilization of this crop than heretofore.... Fortunately for the grower of crimson clover on the ordinary farm, there have been developed recently two simple types of seed-gathering devices which will make it practicable for every farmer to let a portion of his crimson clover stand for seed, gather it in the hull, and immediately bag and house it for sowing later in the season. These devices are described and illustrated in the following pages. In addition, a brief discussion is given of the requirements necessary for successful seed production, as well as of the methods used for producing seed in commercial quantities for the market." -- title pag
