Abstract This study, which is a by-product of a long-term study involving the growing of Norway pine progeny from different localities and individual trees within the natural range of this species, is still not a genetical study in the true sense. It involves only the question of immediate vigor and survival in nursery stock and points the way to obtaining the best seed from this standpoint only. Nothing in these results is intended to suggest that the geographic origin and climatic adaptation of different strains are not important in reforestation,—rather that, within a given locality or range, certain types of trees are much more efficient seed-bearers than others.
C. G. Bates (Fri,) studied this question.
