In my third and fourth letters on American finances and resources, thefollowing comparisons were instituted: Massachusetts and New Jersey,Free States, with Maryland and South Carolina, Slave States; New Yorkand Pennsylvania, Free States, with Virginia, Slave State; Rhode Island,Free State, with Delaware, Slave State; Illinois, Free State, withMissouri, Slave State; the Free States of 1790, with the Slave States ofthat day; the Free States of 1860, with the Slave States of that date.These comparisons were based on the official returns of the Census ofthe United States, and exhibited in each case and in the aggregate thesame invariable result, the vastly superior progress of the Free Statesin wealth, population, and education.
I will now institute one other comparison, Kentucky, slaveholding, withOhio, a Free State.
Kentucky—population in 1790, 73,077; Ohio, none. 18
