In areas with industrial factories, women could find employment on assembly lines for items ranging from locks to canned food. Industrial laundry services employed many women (including inmates of Magdalene asylums who did not receive wages for their work). Women were also commonly employed in the textile mills that sprang up during the industrial revolution in such cities as Manchester, Leeds, and Birmingham. Working for a wage was often done from the home in London, although many women worked as "hawkers" or street vendors, who sold such things as watercress, lavender, flowers or herbs that they would collect at the Spitalfields fruit and vegetable market. Many working-class women worked as washerwomen, taking in laundry for a fee. Animal-breeding in slum flats was common, such as dogs, geese, rabbits and birds, to be sold at animal and bird markets. Housing inspectors often found livestock in slum cellars, including cows and donkeys. Spinning and winding wool, silk, and other types of piecework were a common way of earning income by working from home, but wages were very low, and hours were long; often 14 hours per day were needed to earn enough to survive. Furniture-assembling and -finishing were common piecework jobs in working-class households in London that paid relatively well. Women in particular were known as skillful "French polishers" who completed the finish on furniture. The lowest-paying jobs available to working-class London women were matchbox-making, and sorting rags in a rag factory, where flea- and lice-ridden rags were sorted to be pulped for manufacturing paper. Needlework was the single largest paid occupation for women working from home, but the work paid little, and women often had to rent sewing machines that they could not afford to buy. These home manufacturing industries became known as "sweated industries". The Select Committee of the House of Commons defined sweated industries in 1890 as "work carried on for inadequate wages and for excessive hours in unsanitary conditions". By 1906, such workers earned about a penny an hour.
