Today you enter the Boott Cotton Mill at the Lowell National Historical Park the same way that the thousands who worked there from 1835 through the early twentieth century did—through the white wood Gothic-arched doorway leading to a five-story spiral staircase enclosed in a vertical brick tower.
Although the stairs are made of stone, they are worn by the steps of the countless men, women and children who passed up and down them for almost a century.
They went to work when the bell rang at first light and left twelve to fourteen hours later, depending on the season, when the bell rang again to mark the end of the day. It was grueling work, and many died.
