Possible Venue: in 1842, a group gathered primarily from Norwich’s Second Congregational Church formed a new congregation which met in the town hall until their own church building was constructed on Main Street in 1845. Known as the Main Street Congregational Church, they eventually built a new building on Broadway after the Main Street structure was destroyed by fire in 1854. The Broadway Congregational Church, a much larger building than the first, was built in the Romanesque Revival style between 1855 and 1857.

November 15 - Clinton Hall, Clinton, Massachusetts
Here I am in a hotel—the Clinton House—& a villainous one it is—shabby bed, shabby room, shabby furniture, dim lights—everything shabby & disagreeable [MTL 3: 395]. Note: This letter shows that Sam stayed over in Norwich two nights.
November 16 - Holyoke, Massachusetts
I left Boston without baggage, thinking I would go back there from Norwich the same night—but the trains left at such inconvenient hours that I went from there to Clinton—found a similar state of things — came straight here. But as I am clear out of shirts (wore this one yesterday) I shall take an early train to Boston tomorrow before I go to Danvers.
