Jacob Duche (1737 - 1798) "Caspipina's Letters; Containing Observations on a Variety of Subjects, Literary, Moral and Religious. Written by a Gentleman (Duche) who resided some time in Philadelphia" (R. Crutt Well, Bath, London 1777); contemporary full leather binding with decorated spine, both volumes are present and have loose or detached boards. At the end of Volume One, there are written notations about whom the anonymous letters are referring to, with page 116 being labeled as Francis Hopkinson (1737 - 1791, he is referred to as Amyntor and his wife as Almira). They are described as being "found at (the) harpsichord" and "accompanying the instrument with their voices." The lryics of this song are included, "Oft' shall Schuylkill's rocky shore, with her waving woods around, thy fond name repeating o'er, strive to swell the pleasing sound." These are lyrics from "To Myrtilla" written by Francis Hopkinson himself, and described here in "Caspipina's Letters" as being "composed by a Gentleman of this city, when he was about to leave England a few years ago." --- From the Southern Methodist University website: "Duché’s ideology and political philosophy was expressed in a series of letters that he wrote and published in a local paper in 1772 and 1773 under the pseudonym Tamoc Caspipina, later published as a collection entitled Caspipina’s Letters. Duché’s primary view on government was that its most important role was to maintain an orderly society that would promote stability – the institutions that Duché saw as vital to societal stability were the churches, statehouse, library, college and the river system (which promoted commerce and a stable economy). Duché called for the acceptance of all people and less class distinctions, but didn’t believe in equality for all and was himself a member of the gentry or upper class. Duché believed that the collective happiness of society was equal to justice and stability, and that the enemies of a benevolent government were corruption and party factions – these views would be very evident in his sermon The American Vine. While a supporter of liberty and happiness within society, Duché did prefer order to freedom if the choice had to be made and this view might be more evident in his letter to Washington, written in the midst of the Revolution."
