A first report on the relations between climates and crops . good. Dates when meantemperature ofair thermome-ter in shade— During the season. General character ofsugar crop in Pasde The climatic data given in the above table as directly applicable tothe seasons of growth of the beet root illustrate what should be givenfor any similar study of development of any crop.
