A Union meeting was held at Nashville, Tennessee, on the 23d, which was characterized by unanimity and great enthusiasm. The speakers were, Hon. Andrew Ewing, and Hon. A. J. Donaldson. Resolutions were passed declaring that no State has the constitutional right to secede, and that any such attempt would be revolutionary, and its consequences entail civil strife and bloodshed; that the continual agitation of the slavery issue, will, if persisted in, lead to the total alienation of one section of the Union from the other; that the people of the States have the right, whenever palpably, intolerably, and unconstitutionally oppressed, to throw off the chains that oppress them, but there is no present necessity for the exercise of this right that an attempt to repeal, or failure to enforce the fugitive slave law, will unite all the South, and most probably end in a total separation of the States; and that the Compromise measures of Congress meet their approbation, as the best that, under the circumstances, could be adopted, and they pledge themselves to give them hearty support. A Union meeting was held at Staunton, Virginia, on the 25th of November, over which Col. JAMES CRAWFORD presided. Resolutions were adopted declaring the readiness of those assembled to meet all good citizens of every section, and of every party, on the platform of the Constitution, the Compromise, and the Union; and also expressing the belief that the maintenance of the Compromise in all its parts, without modification or amendment, is essential to the preservation of the Union. Letters were read from a number of distinguished gentlemen who had been invited, but were unable to be present. A large meeting was held at Manchester, N. H., on the 20th of November, at which resolutions were passed expressing devotion to the Union, and a determination to stand by the Compromise measures, and to resist all further agitation of the subject.
