Ethel Maltby Gehres, The Silent Readers: Sixth Reader
“ Raising Cereals.—In some regions the soil and climate are especially suited to raising cereals. For instance, Canada, Minnesota and North Dakota are adapted to raising spring wheat, and this constitutes their chief crop. On the other hand, Kansas is especially suited to raising winter wheat. Illinois and Iowa are the great corn states, because of the particular adaptation of the soil and climate of the corn belt to the production of this cereal. The growing of cereals is more widely extended than any other branch of agriculture. ”
