New Principle in Seed Collecting for Norway Pine a Criticism

The author, a forester and geneticist, presents an analytical criticism of the proof of the principle or law that was set forth and expounded by Mr. C. G. Bates 1 in an article on the source of seed appearing in the May 1931 issue of this Journal. He feels that Mr. Bates' conclusions lack validity because the experimental method used was defective and because the data do not sustain the hypothesis. Although it is not specifically stated and enlarged upon, the importance of considering the rôle of heredity when planning and conducting source-of-seed investigations is implied in the criticism.
