Seedsmen sometimes are asked how they make the seeds they sell. Their reply is "We don't make them. Flowers do." Victor R. Boswell, a Department horticulturist, is shown here in a greenhouse at Beltsville, Md. He is explaining to visitors some aspects of the production of vegetables and seeds: The transfer of pollen by insects so fertilization of flowers can take place; how pollination is controlled so as to breed better plants; some steps in the commercial production of seeds; the growing of plants from cuttings, and so on. This photograph was made by William H. Riess, Jr. He and Dr. Boswell took most of the pictures of seeds that appear in the preceding pages.
