The New International Encyclopædia…
“ There are only two or three States which rival Iowa in the production of cereals. Nearly one-half of its entire land surface is devoted to these products. The State is noted especially for its corn crops, the acreage for which amounts to over one-fourth of its total area, and contributes about one-half of the total value for all crops. Every decade in the State's history shows an increase in the acreage and production of this crop, the largest gain being in the decade 1870-80. The crop is grown most extensively in the central and southwestern counties. ”
