In less than a year after Dr. Rittenhouse had engaged himself in the duties appertaining to the Directorship of the Mint, he was again called upon to assist his countrymen, by the aid of his talents, in effecting an important water-communication, inland, which was then contemplated. An association, called “The Conewago-Canal Company,” was formed in Philadelphia, in pursuance of a law enacted the 13th of April, 1791; by which the sum of fourteen thousand dollars was appropriated, for the purpose of improving the navigation of the river Susquehanna, between Wright’s Ferry (now the thriving town of Columbia) and the mouth of the Swatara. This company consisted of seventeen members, of whom Dr. Rittenhouse was one: and they were incorporated by an act of assembly, passed the 10th of April, 1793. Just about this period, an occurrence took place at Philadelphia, then the seat of the national government, which excited much public feeling at the time, and—contrary to the expectations of some good men of sanguine dispositions—became the source of many political evils, afterwards. This was the formation of what was called the Democratic Society; a political association, produced by the effervescences of the French revolution, while that all-important event was yet viewed in a favourable light by free nations: and of this society, Dr. Rittenhouse was elected President. That Dr. Rittenhouse should have been selected as the President of the Democratic Society, and chosen for that station, can be readily accounted for. This gentleman had evinced, from the commencement of the troubles between the American colonies of Great-Britain and the parent country, an ardent attachment to the cause of his native land. The benevolence of his disposition rendered him the well-wisher of all mankind: hence every thing that, in his view, bore the semblance of oppression, was odious to him. But the wrongs which the country of his nativity, more particularly, experienced, from the unconstitutional claims of the British Parliament, roused those feelings of patriotism, with which his virtuous breast was animated, at the beginning of the American discontents: he was, therefore, an early and decided Whig; and the same principles that induced him to become such, continued to actuate him throughout the contest between the two countries.
