It has a hipped slate roof with a deep overhang supported by large wooden brackets.

Delaware and Raritan Canal: The Delaware and Raritan Canal (D&R Canal) is a canal in central New Jersey, United States, built in the 1830s, that served to connect the Delaware River to the Raritan River.  It was intended as an efficient and reliable means of transportation of freight between Philadelphia and New York City, especially coal from the anthracite fields in eastern Pennsylvania.  Before the advent of the railroads, the canal allowed shippers to cut many miles off the route from the Pennsylvania coal fields, down the Delaware, around Cape May, and up along the (occasionally treacherous) Atlantic Ocean coast to New York City.

Nicolas-François Guillard: Nicolas-François Guillard (16 January 1752 – 26 December 1814) was a French librettist.  He was born in Chartres and died in Paris, the recipient of a government pension in recognition of his work writing librettos.  He was also on "Comité de Lecture" of the Paris Opéra.  One of the foremost of the French librettist of his generation, he wrote libretti for many noted composers of the day, including Salieri ("Les Horaces") and in particular Sacchini ("Oedipe à Colone", amongst many others).  His most famous work is "Iphigénie en Tauride", his first libretto, set by Gluck after the composer had initially rejected it.  Gluck collaborated with Guillard to heavily recast the libretto, not only to suit Gluck's artistic preferences, but also to accommodate pre-existing music that Gluck borrowed, both from himself and from other composers, when composing the opera.
