The records of the United States Army, which hired civilian workers in the nineteenth century, have produced a large sample of wage rates. New estimates of nominal daily wage rates from 1820 to 1856 are presented. There is no evidence of a long-term increase in the skill differential. The growth of real wages in the Northeast appears to have been slower and more erratic than previously thought. Regional trends in wages are consistent with other evidence on patterns of regional growth and internal migration.
