Excerpt from The Great Plains and the Supply of Wheat The Great Plains has no commonly accepted fixed boundary. In general the mountains on the west, the 20-inch rainfall line on the east, the Canadian boundary on the north, and the southern edge of the high plains escarpment on the south, are taken to be the limits of the Great Plains. This region, without embracing any entire State, includes parts of 10 States commonly designated as the Great Plains States are: Montana, North Dakota, South Dakota, wyoming, Nebraska, Colorado, Kansas, New Mexico, Oklahoma, and Texas. For the purposes of this report an area termed the high-risk area has been delineated, indicating approximately the part of the Great Plains in which wheat growing is accompanied by the greatest climatic hazards (fig. Irrigated areas insofar as practicable have been excluded. This area has been delineated primarily on the basis of the judgment of a number of agricultural workers in the Great Plains, supported by actuarial data from the Federal crop Insurance Corporation. It should be regarded as a preliminary delineation, subject to later refinement. In particular, it should be pointed out that the degree of risk is by no means the same ln all parts of this area. Or convenience in the use of statistics, the area boundaries follow county lines. It will be noted that a boundary between the areas of spring-wheat and Winter-wheat production has been drawn. This indicates only that one predominates over the other. A wide belt is found in which both are grown. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
