Except for the one-story rear addition, this small, dressed Indiana limestone ashlar library has not changed since it opened in 1904. Architect Hawley of Philadelphia was a native son; his father was a local teacher and state senator. Hawley finished his drawings for the library in the summer of 1900 while visiting his mother at nearby Heart Lake. The Beaux-Arts design with an Ionic distyle in antis portico was standard for libraries at the time. Yet the striking similarity of Hawley's library and Brown University's larger John Carter Brown Library (1898–1904, Shepley, Rutan and Coolidge) appears more than coincidental. The differences are size and Hawley's omission of the cornice cresting and his addition of a copper clock cupola. Charles C. Pratt, a prominent citizen and later congressman, built the library in memory of his parents, Ezra and Mary Pratt, who founded the library in their home in 1892. St. Mark's Episcopal Church (1827) at 115 Main Street is a mixture of Greek and Gothic Revival detail.
