What was going on in the South during the thirties and forties of the last century? There were varying shades of opinion and mixed motives and fluctuating political currents. In the first place cotton-growing had been made profitable by the invention of the cotton-gin. This machine for separating the seeds from the fibre of the cotton plant caused an industrial revolution in the world, and its moral consequences were no less sweeping. It changed the slaveholder's point of view of the whole slavery question. The previously prevailing idea that slavery was morally wrong, and an evil to both master and slave, gradually gave way to the belief that it was beneficial to both, that it was an agency of civilization and a means of bringing the blessings of Christianity to the benighted African. This change of sentiment in the South, which became very marked in the early thirties, has been ascribed to the bad language of the abolitionists of the North. People said that the prime cause of the trouble was that Garrison and his followers did not speak easy. They were too vociferous. They used language calculated to make Southerners angry and to stir up slave insurrection. But how could anybody draw the line between different tones of voice and different forms of expression? Thomas Jefferson was not a speak-easy. He said that one hour of slavery was fraught with more misery than ages of that which led us to take up arms against Great Britain. If Garrison ever said anything more calculated to incite slaves to insurrection than that, I cannot recall it. On the other hand, Elijah Lovejoy, at Alton, Illinois, was a speak-easy. He did not use any violent language, but he was put to death by a mob for making preparations to publish a newspaper in which slavery should be discussed in a reasonable manner, if there was such a manner.
