Thomas Jefferson in letter to John Holmes-1820 concerning the Missouri Compromise--
"but this momentous question, like a fire bell in the night, awakened and filled me with terror. I considered it at once as the knell of the Union. it is hushed indeed for the moment. but this is a reprieve only, not a final sentence. a geographical line, coinciding with a marked principle, moral and political, once concieved and held up to the angry passions of men, will never be obliterated; and every new irritation will mark it deeper and deeper."
