Every memorial and petition had been disposed of according to the wishes of the senators from the slaveholding States; but Mr. Calhoun deemed it due to those States to go further, and to obtain from the Senate declarations which should cover all the questions of federal power over the institution of slavery: although he had just said that paper reports would do no good. For that purpose, he submitted a series of resolves--six in number--which derive their importance from their comparison, or rather contrast, with others on the same subject presented by him in the Senate ten years later; and which have given birth to doctrines and proceedings which have greatly disturbed the harmony of the Union, and palpably endangered its stability. The six resolutions of this period ('37-'38) undertook to define the whole extent of the power delegated by the States to the federal government on the subject of slavery; to specify the acts which would exceed that power; and to show the consequences of doing any thing not authorized to be done--always ending in a dissolution of the Union. The first four of these related to the States; about which, there being no dispute, there was no debate. The sixth, without naming Texas, was prospective, and looked forward to a case which might include her annexation; and was laid upon the table to make way for an express resolution from Mr. Preston on the same subject. The fifth related to the territories, and to the District of Columbia, and was the only one which excited attention, or has left a surviving interest. It was in these words: "_Resolved_, That the intermeddling of any State, or States, or their citizens, to abolish slavery in this District, or any of the territories, on the ground or under the pretext that it is immoral or sinful, or the passage of any act or measure of Congress with that view, would be a direct and dangerous attack on the institutions of all the slaveholding States."
