Summary

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.

Printing and publishing, and the making of foundry and machine-shop products, are important industries. The manufacture of pearl buttons has developed during the decade into a thriving industry. The material out of which the buttons are made is the shell of the fresh-water mussel. None of the foregoing industries is centralized at any one place. The lumber industry is greatest along the Mississippi River, but the industries in general are well distributed throughout the State.

Iowa is admirably provided with transportation facilities. Water transportation is afforded by the Mississippi River on the east. Owing to the State's situation, a large number of the most important railroad lines of the country pass through it. Des Moines is the centre of a large number of lines, and every section of the State is amply provided. It is interesting to note that in the western part most of the railroads follow the course of some river, so that all the larger tributaries to the Missouri River are paralleled by a railroad, thus giving them a northeast and southwest direction.
