The federal Senate are the representatives of the sovereignties of their respective states. A second branch, thus constituted, is a novelty in the history of the world. Instead of an hereditary upper house, the American Confederacy has created a body, the temporary representatives of their component sovereignties, dignified only by their being the immediate delegates and guardians of sovereign states selected from the body of the people for that purpose, and for no reasons, but their possessing the qualifications necessary for their station. We find then in this body, none of the evils of aristocracy apprehended by those who have drawn their reasonings from an erroneous comparison with the upper house of Britain, and all the benefits of a second branch, without hazarding the rights of the people in the smallest particular.
-Tench Coxe, 1787
