Excerpt from "Forest Conditions" In ShelterbeltsTo assure reliability of our seed sources, we must first of all define the desirable tree form and then define the best seed collection sites. Then an adequately trained man should examine not only the proposed seed collection sites but also the individual trees from.which seed is to be taken. This procedure will more nearly assure seed provenience and enable maintenance of seed source records in useable form.Our expectations that in time our plantings would furnish the seed 'we need would be realized if we had done our work perfectly, but since we have not, we can not expect our plantings through 1940 to be better seed sources than other existent sources except to the very slight extent that five years of natural selection could have improved it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
