The center of farm values moved from near the same point to a point 39 miles northwest of Springfield, Illinois. The center of corn production moved from 86 miles southeast of Columbus, Ohio, to 54 miles southwest of Springfield, Illinois; the average center of wheat raising moved from 57 miles northeast of Columbus, Ohio, to 70 miles west of Des Moines , Iowa. The center of oat raising shifted from the same locality to a point 58 miles north of Burlington, Iowa. About one third of the farms in the United States are occupied by tenants who pay a cash rent or give the owner of the land a share of the produce. Rather more than one-third of our people live on farms. See Agriculture ; Cattle ; Horses; Sheep ; Chickens
