In the City of New York, meantime, there had been a growing feeling of apprehension at the tone of current political discussions and at the opposition everywhere manifested at the North to the Fugitive Slave Law, and on the 30th of October a very large public meeting was held at Castle Garden of those who were in favor of sustaining all the peace measures of Congress, and of taking such measures as would prevent any further agitation of the question of slavery. Mr. GEORGE WOOD, an eminent member of the New York Bar, presided. A letter was read from Mr. WEBSTER, to whom the resolutions intended to be brought forward had been sent, with an invitation to attend the meeting. The invitation was declined, but Mr. WEBSTER expressed the most cordial approbation of the meeting, and of its proposed action. He concurred in "all the political principles contained in the resolutions, and stood pledged to support them, publicly and privately, now and always, to the full extent of his influence, and by the exertion of every faculty which he possessed." The Fugitive Slave Law he said, was not such a one as he had proposed, and should have supported if he had been in the Senate. But it is now "the law of the land, and as such is to be respected and obeyed by all good citizens. I have heard," he adds, "no man, whose opinion is worth regarding, deny its constitutionality; and those who counsel violent resistance to it, counsel that, which, if it take place, is sure to lead to bloodshed, and to the commission of capital offenses. It remains to be seen how far the deluded and the deluders will go in this career of faction, folly, and crime. No man is at liberty to set up, or to affect to set up, his own conscience as above the law, in a matter which respects the rights of others, and the obligations, civil, social, and political, due to others from him. Such a pretense saps the foundation of all government, and is of itself a perfect absurdity; and while all are bound to yield obedience to the laws, wise and well-disposed citizens will forbear from renewing past agitation, and rekindling the names of useless and dangerous controversy. If we would continue one people, we must acquiesce in the will of the majority, constitutionally expressed; and he that does not mean to do that, means to disturb the public peace, and to do what he can to overturn the Government." The resolutions adopted at the meeting, declared the purpose "to sustain the Fugitive Slave Law and its execution by all lawful means:" and that those represented at the meeting would "support no candidate at the ensuing or any other election, for state officers, or for members of Congress or of the Legislature, who is known or believed to be hostile to the peace measures recently adopted by Congress, or any of them, or in favor of re-opening the questions involved in them, for renewed agitation."
