Before proceeding to discuss the regions which have been outlined, it is necessary to make clear what is meant by "region” as the term is here employed. A region is used in this discussion as an area of land in which the soil pattern is generally similar and in which the climatic conditions also have a restricted range. It is obvious that uniformity of either- soil or climate is not possible unless each region is of very small dimensions. From accumulated experienced, the main important differences in climatic and soil conditions in various parts of the agricultural areas are, however, appreciated by trained agriculturists and this experience has been utilised in preparing the accompanying map. For example: the difference between 8 and 10 inches of winter rainfall in the outer wheatbelt areas is of considerable importance, whereas in the much wetter districts of the extreme South West the difference between 35 and 45 inches in the same period may have considerably less significance.
