In this letter Mr. Adams states and explains the origin of the treaty of peace and alliance between Southern nullification and Northern pro-slavery, and the nature and consequences of that alliance. In the course of his illustrations on this subject he repels, with an irresistible power of argument, the attempt of the slaveholder to sow the seeds of discord among the freemen of the North. "The condition of master and slave is," he considered, "by the laws of nature and of God, a state of perpetual, inextinguishable war. The slaveholder, deeply conscious of this, soothes his soul by sophistical reasonings into a belief that this same war still exists in free communities between the capitalist and free labor." The fallacy and falsehood of this theory he analyzes and exposes, and proceeds to state and reason upon various measures of Congress connected with these topics, at great length, and with laborious elucidation.[4] [4] For this letter see _Niles' Weekly Register_, New Series, vol. V., p. 55. On the 27th of October, 1838, Mr. Adams addressed a letter to the district he represented in Congress, in which he touched on those points of national policy which most deeply affected his mind. Among many remarks worthy of anxious thought, which subsequent events have confirmed and are confirming, he traces the "smothering for nearly three years, in legislative halls, the right of petition and freedom of debate," to the influence of slavery, "which shrinks, and will shrink, from the eye of day. Northern subserviency to Southern dictation is the price paid by a Northern administration for Southern support. The people of the North still support by their suffrages the men who have truckled to Southern domination. I believe it impossible that this total subversion of every principle of liberty should be much longer submitted to by the people of the free states of this Union. But their fate is in their own hands. If they choose to be represented by slaves, they will find servility enough to represent and betray them. The suspension of the right of petition, the suppression of the freedom of debate, the thirst for the annexation of Texas, the war-whoop of two successive Presidents against Mexico, are all but varied symptoms of a deadly disease seated in the marrow of our bones, and that deadly disease is slavery."
