Excerpt from Proceedings of the International Conference on Plant Hardiness and Acclimatization, 1907: Held in the Rooms of the American Institute of the City of New York and in the Museum Building of the New York Botanical Garden, October 1st to 3rd, 1907

Now, however, by the light of present knowledge, profiting by the splendid results of Nilsson with cereals, all such opera tions may be carried out with much greater exactitude and much more rapidly than by the old-time method of trial and error, most wasteful of Skilled energy and time - consuming in human life. Today we may expect as much from the breeder in ten years as he might have been able to accomplish in the previous half century. The realization has been tardily reached that if we are to make alterations in the hereditary qualities of the plants useful to us, we must make an accurate analysis to dis close the constituents Of the species with which we are dealing, and having this information we may proceed with the exactitude of the chemist making compounds and extractions in his labora tory.

With SO much to our credit in the way of advance made in knowledge of the nature of the plant and its behavior, the other important task which confronts us is that of making a similarly exact study of climate and of all of the factors which constitute the complex set of conditions which we term environment.
