Skilled workers were brought over from England to ply their trade at the iron works. These emigrants did not fit in with the local Puritan society and often ran afoul of its laws. Many ironworkers were arrested for crimes such as drunkenness, adultery, gambling, fighting, cursing, not attending church, and wearing fine clothes. The less experienced local men who worked at the Iron Works met with frequent and sometimes fatal accidents. Another source of labor was indentured servants. Indentured servants typically worked at the Iron Works for three to seven years for little or no pay in exchange for their passage to Massachusetts and the provision of food, clothing, housing, and other necessities. Following the Battle of Dunbar in 1650, 60 Scottish prisoners of war were sent to the Iron Works to work as indentured servants. 35 or 37 of the 60 Scots intended for the Iron Works were employed there, while the remainder were sold for between 20 pounds and 30 pounds each to various interests in Massachusetts, New Hampshire, and Maine. The Scots mostly worked as unskilled laborers, performing tasks like chopping wood. Some learned skills such as making charcoal, blacksmithing and carpentry. Most Scots were able to gain their freedom after seven years and afterwards they remained in Massachusetts or moved to Maine, where they started families and assimilated into Puritan society.
