Chace (sometimes misspelled 'Chase') cotton mill was actually located just across the river in Burlington, Vermont. The building still stands, and has primarily been converted into office and business space. It is part of the Winooski Falls Mill District, which is on the National Register of Historic Places. There's lots of good info available online - you might be interested in searching for photos by Lewis Hine. He took a number of photos of workers at the mill.
