If the present partial check to immigration should continue, though it is hardly probable, the number of immigrants for the decade ending in 1870, may possibly be reduced from 2,707,624 to 1,500,000.

The rate of progress of the population of the United States has much exceeded that of any of the European nations. The experienced statisticians in the present Congress can readily furnish the figures precisely showing the comparative rate.
