Nahum Howe built a saw mill, stave mill and chair back manufactory in 1850 that was located on road 31 in Fitzwilliam, New Hampshire. It is operated by water-power and a twenty horse-power engine. It also appears that Nahum Howe owned a store from 1848-1849 in Fitzwilliam and in 1853 he opened a store in Howeville that operated until 1867 when he closed his manufacturing business.
