revenue was at present and had been for many years past, derived solely from the sale of public lands, and from the customs or duties levied on imported articles of various kinds. The payment of these duties was entirely a voluntary tax, as in order to avoid it, it was only necessary to refrain from the use of articles on which they were imposed. As for Mr. T's argument about the standing army, employed in keeping down the slaves, its value might be judged from the fact, that, though even according to Mr. T's own showing, the slave population amounted to two and a half millions, the army was composed of only six thousand men, scattered along three frontiers, extending two thousand miles each. Throughout the whole slaveholding states there were not probably fifteen hundred soldiers. The charge was, in fact, complete humbug, founded upon just nothing at all. Mr. Thompson's seventh charge was, that Congress refused to suppress the internal slave-trade. This was easily answered. There was in America not one individual among five hundred who believed that Congress had the power to do so. And, although he (Mr. B.) believed that Congress had power to prevent the migration of slaves from state to state, as fully as they had to prevent the importation of them into the states from foreign countries; and that the exercise of this power, would prevent, in a great degree, the trade in slaves from state to state, yet very few concurred with him even in this modified view of the case. And it must be admitted that the exercise of such a power, if it really exists, would be attended with such results of unmixed evil at this time, that no one whatever would deem it proper to attempt, or possible to enforce its exercise. It was next said, that as Missouri, a slaveholding state, had been admitted into the Union after the full consideration of the subject by Congress, therefore the nation had become identified with slavery, and responsible for its existence, at least in Missouri. But on the supposition that, before receiving Missouri as a member of the confederacy, it had been demanded of her that she should abolish slavery; and supposing Missouri had acceded to the terms proposed, that she had really given her slaves freedom, and been added to the Federal Union in consequence: suppose Missouri had done all this; what was there to prevent her from re-establishing slavery so soon as the end she sought was gained. No power was possessed by the other states in the matter, and all that could have been said was, that Missouri had acted with bad faith--that she had broken a condition precedent--that she had given just cause of war. According to the most latitudinarian notions, this was the extent of the remedy in the hands of Congress. But Mr. Thompson, being a holder of peace principles--if we may judge by his published speeches--must admit it to be as really a sin to kill, as to enslave men; so that, in his own showing, this argument amounts to nothing. But when it is
