Your aristocracy, whatever may be their vaunts, are conscious of their military weakness, and shrink from any contest which may cause a foreign army to plant the standard of emancipation upon their soil. The very idea of an armed negro startles their fearful imaginations. This is disclosed on innumerable occasions, but was conspicuously manifested in a debate in the Senate. In July, 1842, a Bill to regulate enlistments in the naval service being under consideration, Mr. CALHOUN proposed an amendment, that negroes should be enlisted only as _cooks_ and _stewards_. He thought it a matter of _great consequence_ not to admit blacks into our vessels of national defence. Mr. BENTON thought _all arms_, whether on land or sea, ought to be borne by the white race. Mr. BAGBY. "In the Southern portion of the Union, the great object was to _keep arms and a knowledge of arms_ out of the hands of the blacks. The subject addressed itself to every Southern heart. Self-preservation was the first law of nature, and the South must look to that." On the motion of Mr. PRESTON, the bill was so amended as to include the army. And think you that men, thus in awe of their own dependents, shuddering at a musket in the hands of a black, and with a population of two millions and a half of these dreaded slaves, will expose themselves to the tremendous consequences of a union between their domestic and foreign enemies? Of the four who voted against the British treaty, probably not one would have given the vote he did, had he not known to a certainty that the treaty would be ratified.
