The germ of dissolution of our federal government is in the constitution of the federal judiciary; an irresponsible body, (for impeachment is scarcely a scare-crow) working like gravity by night and by day, gaining a little today and a little tomorrow, and advancing its noiseless step like a thief, over the field of jurisdiction, until all shall be usurped from the States, and the government of all be consolidated into one.
Letter to Charles Hammond, August 18, 1821.
