At the close of the eighteenth century, the black smoke of the iron shops, the glass manufactory, the boat yards, the distillery, the brewery, the tanneries, the brickyards, and the increasing number of dwelling houses had already given the town a sombre hue. Industry went forward with leaps and bounds, and manufactories on a larger scale were set up. They were insignificant, if compared with even the medium-sized establishments of to-day, but were large and important in the eyes of people who, prior to the American Revolution, had been practically prohibited from engaging in any manufacturing by their English masters. Cotton mills were established, as were iron foundries, nail factories, engine shops, a tinware manufactory, a pipe manufactory, and in 1808 a second glass works, that of Robinson & Ensell.[138] The extent of the plants can be gauged, when it is known that one of the nail factories employed thirty men, the tinware manufactory twenty-eight men, and one of the cotton mills twelve men.[139] In 1804, the Bank of Pennsylvania opened a branch in Pittsburgh. A stage line from Chambersburgh to Baltimore and Philadelphia was placed in operation in the spring of 1803.[140] In 1804 this was extended to Pittsburgh, the first coach from Pittsburgh to Philadelphia being run on July 4th. Religion was now keeping pace with the increase in population and the growth in material prosperity. Hitherto those who were religiously inclined were obliged to attend the services of either the German or the Presbyterian church. Other churches were now brought into existence. The Episcopalians formed an organization in 1805, under the name of “Trinity Church,” and began the erection of their brick octagonal building, on the lot bounded by Liberty, Seventh, and Wood streets, which was a landmark in its day.
