ABSTRACT
It would, perhaps, seem desirable to preface a study of the land system by an analysis of the problem of land utilization; but, because of the limitations of our technical knowledge of agriculture, we must confine ourselves to a description of the fundamental data which are necessary as a basis for the later discussions. These data, which constitute the agricultural calendar, are arranged in the form of a table (Table 1) for ready reference. This table will serve the purpose of showing graphically the co-ordination of climate, crop growth, and agricultural activities. The following pages will be devoted to an explanation of the various columns in the calendar.
