Like most people in the eighteenth century, Edmund Harrold made his living by working multiple jobs. A barber by training and title, he rented a small shop in Manchester where he shaved customers' heads, bought and sold hair, and crafted wigs. In the hours unfilled by shaving, cutting and weaving, he also performed 'cupping', a medical service offered to lactating women. In addition to these principal employments, Harrold undertook other temporary income-generating activities or by-employments. He worked as a book dealer, and eventually as an auctioneer, selling various items in alehouses within Manchester and in outlying towns. In 1713, when times got hard, Harrold took on paid employment offered by civic authorities and worked as a dog muzzler. He lent out money, when he had it, earning ten percent interest on his holdings. Harrold's household also depended upon the productive activities undertaken by his wife and dependents. His wife Sarah managed the rental of a room in their house to lodgers, retailed secondhand clothing, and operated a business washing clothes. In addition to these income-generating activities, Sarah contributed to the household's maintenance by producing foodstuffs including bread. 1 Edmund Harrold's experience of multiple employments, described in a diary that he kept between 1712 and 1715, was typical of the occupational fluidity that characterized eighteenth-century working lives. Whether measured by the tools and goods in probate inventories, the work or maintenance activities described by the litigants and witnesses in court records, or the debts that individuals contracted, we know that occupational titles did not fully describe men's productive activities and that occupational plurality was the norm. Individuals tended to combine different forms of work, and to move during their lives from one form of employment to another. 2 For Harrold and others, this occupational plurality was a feature of maintaining what he described as a 'computency of living' in a precarious economic environment. 3
