I hope Congress, before they adjourn, will take into very serious Consideration the necessary Amendments of the Constitution. Those whom I call the best—the most judicious & disinterested Fœderalists, who wish for the perpetual Union, Liberty & Happiness of the States and their respective Citizens many of them, if not all are anxiously expecting them—They wish to see a Line drawn as clearly as may be, between the federal Powers vested in Congress and the distinct Sovereignty of the several States upon which the private and personal Rights of the Citizens depend. Without such Distinction there will be Danger of the Constitution issuing imperceptibly, and gradually into a Consolidated Government over all the States, which, altho it may be wished for by some, was reprobated in the Idea by the highest Advocates for the Constitution as it stood without amendmts. I am fully persuaded that the People of the United States being in different Climates—of different Education and Manners, and possest of different Habits & Feelings under one consolidated Governmt. can not long remain free, or indeed under any Kind of Governmt. but Despotism.
