They flattered themselves that they had put a period to the agitation, and that the irritating question was now cast outside the domain of American politics. Perhaps they did not sufficiently reflect that the same power which had established the boundaries of slavery might, when the opportunity was ripe, erase them. The slavery agitation was, however, only in its infancy. It had within it a vital and irrepressible element of growth. With the advance of civil liberty, the growth of education, it, too, must necessarily make progress. As yet it was in the hands of so-called "fanatics." Respectable statesmanship, having made the Missouri Compromise, would have no more of it. [Sidenote: The "Liberty Party."] [Sidenote: Garrison.] It was early in General Jackson's presidency that the small but determined "Liberty party" of the North began to attract attention by what was considered the extravagance of its utterances, and the absurdity of its proposals. The Quaker Lundy published his "Genius of Universal Emancipation"; Garrison put forth the "Liberator" at Boston; and soon, in various parts of the Union, abolition tracts and fanatical orators brought down upon them not only the execration of the South, but the assaults of northern mobs. An insurrection, under the lead of a negro named Turner, broke out in Virginia, and massacres and burnings followed. The Georgia Legislature put a price upon Garrison's head; and that devoted advocate of human freedom responded by founding the New England Anti-Slavery Society--an example soon followed in various places through the North. [Sidenote: Sympathy for the Slaves.] [Sidenote: Lovejoy Killed.] The cause was right, and grew despite every obstacle of mob violence, persecution, contempt, and, not the least, the indignant hostility of respectable statesmanship. Yet evidences began to appear, here and there, that the sympathy even of official responsibility was gradually leaning to the principle of liberty. The Massachusetts Supreme Court declared the child Med, whose master had brought her to Boston, to have become by that act free. There was still, however, much suffering in store for the anti-slavery advocates. Garrison, in attempting to speak before the Female Anti-Slavery Society in Boston, was dragged through the streets by an enraged mob, and was only saved from death by being hurried to the jail as a refuge. A hall in Philadelphia which had been desecrated by an abolition conference, was burned. Elijah Lovejoy, an Illinois abolition editor, was killed by a mob. These are a few among many examples of the violence with which the abolitionists were treated.
