Excerpt from A First Report on the Relations Between Climates and Crops
The very extensive problem suggested by the title of this report involves, first, a general study of meteorology in its relations to vegetable and animal life; second, the determination of the effect of climate upon the growth and distribution of staple crops; third, the determination of the climatic conditions and the localities best suited to the growth of special varieties of plants and seeds; fourth, the statistics of the extent of the areas best adapted to each of the more important crops; fifth, the separate and the combined effects of tem perature, rainfall, and sunshine, both in their normal and abnormal proportions, upon the annual yields of the staple cr0ps. But such study necessitates great labor and much time, andas the first step in any such investigation consists in the critical examination of the work already done by others, in order to prevent unnecessary dupli cation and avoid the troubles that others have experienced, therefore the reader must consider this first report as only a brief introduction to our knowledge of the relations between climates and crops.
Three ways are generally recognized as affording our only methods of advancing our knowledge of our subject, Viz, physiological, experi mental, and statistical. I shall therefore endeavor to present the question of climates and Crops from these three points of View.
