- 1762, describing Belmont Mansion, estate of Judge William Peters, near Philadelphia, Pa. (quoted in Pennsylvania Magazine of History and Biography 12: 454-55) 
- "Then went to William Peters's house having some acquaintance with his wife. She was at home and with her daughter Polly received us kindly in one wing of the house. After a while passed through a covered passage to the large hall well furnished, the top adorned with instruments of music, coat of arms, crests and other ornaments in stucco, its sides by paintings and statues in bronze. From the front of this hall you have a prospect bounded by the Jerseys like a blue ridge. A broad walk of English Cherry trees leads down to the river. The doors of the house opening opposite admit a prospect of the length of the garden over a broad gravel walk to a large handsome summer house on a green. From the windows a vista is terminated by an obelisk. On the right you enter a labyrinth of hedge of low cedar and spruce. In the middle stands a statue of Apollo. In the garden are statues of Diana, Fame and Mercury with urn. We left the garden for a wood cut into vistas. In the midst is a Chinese temple for a summer house. One avenue gives a fine prospect of the City. With a spy glass you discern the houses and hospital distinctly. Another avenue looks to the obelisk."
