From an extensive study of the influence of the source of seed of shortleaf pine, pitch pine, tulip poplar and white ash upon its quality, the author concludes that size of fruit is a poor index, but that weight is roughly proportional to germinative energy and seedling vigor; that the source as to location in the crown, has little bearing on germinability; and, that cones which mature and scatter their seed first have heavier seed than those ripening later, but that an inordinately large number are hollow. The article points out the extreme variations among individual trees as to quantity and quality of seed produced.
