Market & Industrial Change: Production, Labor & Technology — Print · Grade 7 Social Studies

Part 1 · Dividing the work

Take shoemaking. One man cutting, stitching, lasting and finishing produces a pair and knows every stage. Divide it among ten people, each doing one operation all day, and the total rises sharply: nobody changes tools, each movement is practised thousands of times, and the slowest step sets a pace everyone matches.

The same logic produced interchangeable parts. If every trigger fits every musket, a gun can be assembled from a bin rather than filed to fit by a gunsmith, and repaired by swapping a part. Eli Whitney famously demonstrated the idea to Congress in 1801 and did not in fact achieve it; the Springfield Armory got there by the 1840s through machine tools and precise gauges, and the method spread to clocks, sewing machines and eventually everything.

The machine that mattered most to this period, though, worked the other way. Eli Whitney’s cotton gin, patented in 1794, let one worker clean as much short-staple cotton in a day as fifty could by hand. That did not replace labour; it multiplied the value of having more of it, because cleaning had been the bottleneck and growing and picking now were. Cotton production rose from a few thousand bales in the 1790s to over two million by 1850, and slavery, which many of the founders had expected to fade, became the most profitable thing in America.

Notice what moves. Skill shifts out of the worker and into the machine, the gauge and the layout of the shop. That is why the system raised output and lowered wages at the same time, which looks contradictory until you see that the thing being paid for had changed.

Part 2 · Lowell

American manufacturers faced a labour problem the English did not: land was cheap, so men who disliked a mill could farm instead. The answer at Lowell, Massachusetts, in the 1820s was to recruit a workforce with fewer options — young unmarried women from New England farms, who came for a few years before marrying.

The system was carefully built to reassure their families. The women lived in company boarding houses with curfews and compulsory church attendance, supervised by matrons. They worked roughly twelve to fourteen hours a day, six days a week, in rooms kept humid so the thread would not snap and loud enough to damage hearing, and earned around three dollars a week before board was deducted — less than a man would get, and more cash than a farm daughter had ever had of her own.

The mills themselves were an engineering achievement worth noticing. Francis Cabot Lowell had memorised the design of British power looms on a visit in 1810 — exporting the plans was illegal — and reproduced them at Waltham in 1814 in the first factory anywhere to take raw cotton in at one end and send finished cloth out the other. By the 1830s Lowell had dozens of mills driven by the Merrimack river and was the second-largest city in Massachusetts.

That last point explains why they came. A woman at Lowell held her own wages, and many sent money home or paid a brother's college fees; some saved for themselves. They produced a literary magazine, the Lowell Offering, and the mills were shown to foreign visitors as proof that industry need not produce the misery of Manchester.

Part 3 · When the women struck

The arrangement did not stay comfortable. As competition grew, owners cut rates and increased the number of machines each worker tended, a practice called the stretch-out. In 1834 and again in 1836 the Lowell women “turned out” — walked off in their thousands, marched through the streets and petitioned. They lost the first and substantially won the second, when a rent rise in the boarding houses was withdrawn.

They also organised formally. Sarah Bagley founded the Lowell Female Labor Reform Association in 1845, which gathered thousands of signatures for a ten-hour day and testified before the Massachusetts legislature — among the first times American working people gave evidence to a government about their conditions.

What they said is worth quoting in substance: that daughters of men who fought the Revolution would not be made slaves, and that selling their labour did not mean selling themselves. They were using the Revolution's own language, which is the pattern you have seen with Abigail Adams and will see again at Seneca Falls. By the 1850s the mills had replaced them largely with Irish immigrant families, who could be paid less and had nowhere to return to.

Part 4 · Time, and who owns it

The deepest change was to time itself. Farm and workshop work follows the task and the daylight — you work until the field is done, harder at harvest, little in deep winter. Factory work follows the clock, and the mill bell rang for rising, for breakfast, for the start of work, for the end.

Workers resented the bell more than almost anything, and with reason: some mills were accused of running the company clock slow at the dinner break. The quarrel over the ten-hour day was really a quarrel about who owned the hours of the day, and it ran for decades before legislation settled any of it.

Children were in these mills too, and in larger numbers in the smaller operations than at Lowell. In the Rhode Island system, whole families were hired together and children of nine or ten tended machines for the same twelve-hour day, because their small hands reached into places an adult could not and because they could be paid a fraction. Massachusetts passed the first state law limiting children’s hours in 1842, and enforcement was close to nonexistent.

That change outlasted every machine in this unit. Clock time, the shift, the timetable and the idea that lateness is a fault rather than an inconvenience all arrive with the factory. You still live by it, which makes this the closest thing in the chapter to a direct inheritance.
