Having made trial of the strong arm of the mob as an instrument for putting down the Abolitionists, and been quite confounded by its unexpected energy and unmanageableness, Boston was well disposed to lay the weapon aside as much too dangerous for use. For the wild-cat-like creature might take it into its head, when once it had got a taste of blood, to suppress some other isms in the community besides Abolitionism. No, no, the gentlemen of property and standing in the community had too much at stake to expose their property and their persons to the perils of any further experiments in that direction, even for the sake of expressing their sympathy for their dear brethren in the South, or of saving the dear Union into the bargain. Another method more in accord with the genius of their high state of civilization, they opined, might be invented to put the agitation and the agitators of the slavery question down. The politicians thereupon proceeded to make this perfectly wonderful invention. Not the strong arm of the mob, quoth these wiseacres, but the strong arm of the law it shall be. And the strong arm of the law they forthwith determined to make it.

Massachusetts was hearkening with a sort of fascination to the song of the slave syren. And no wonder. For the song of the slave syren was swelling and clashing the while with passionate and imperious energy. South Carolina had led off in this kind of music.
