The society was more than local in character, similar societies being in existence in New York, Philadelphia, and in the neighboring village of Washington. At a later day the Mechanical Society of Pittsburgh produced plays, some of which were given in the grand-jury room in the upper story of the new court house. The society also had connected with it a circulating library, a cabinet of curiosities, and a chemical laboratory.
