The area of the nine Free States enumerated in 1790, is 169,668 square miles, and of the eight slaveholding States, 300,580 square miles, while the population of the former in 1790 was 1,968,455, and of the latter, 1,961,372; but, in 1860, these nine Free States had a population of 10,594,168, and those eight Slave States only 7,414,684, making the difference in favor of these Free States in 1860 over those Slave States, 3,179,844, instead of 7,083 in 1790, or a positive gain to those Free States over those Slave States of 3,172,761. These Free States enumerated in 1790 and 1860, were the six New England States, New York, New Jersey, and Pennsylvania; and the Slave States were Delaware, Maryland, Virginia, North and South Carolina, Georgia, Tennessee, and Kentucky: yet we have seen that the area of those Slave States was nearly double that of those Free States, the soil much more fertile, the climate more salubrious, as shown by the Census, that the shore line, including main shore, bays and sounds, islands and rivers, to head of tide water, was, for those Free States, 4,480 miles, and for those Slave States, 6,560 miles. Thus it is clear that the increase of population of these Slave States should have far exceeded that of those Free States. The population of these Slave States per square mile in 1790 was 6 (6.52), and in 1860, 24 (24.66), and of those Free States in 1790, was 11 per square mile (11.60), and in 1860, 62 per square mile (62.44). Thus, while the increase of those Slave States from 1790 to 1860 was only 18 per square mile, that of those Free States was nearly 51 per square mile (50.84), or in very nearly a triple ratio, while in wealth and education the proportionate progress was much greater. No cause except slavery can be assigned to this wonderful difference, for the colonists of Maryland were distinguished for education, intelligence, and gentle culture. Lord Baltimore was a statesman and philanthropist, and his colony was a free representative government, which was the first to repudiate the doctrine of taxation without representation, and the first to introduce religious toleration. While Maryland has produced many of the most eminent soldiers, statesmen, and jurists, her relative decline in power, wealth, and population has been deplorable, and is attributable exclusively to the paralyzing effect of slavery.
