Answer:
New England merchants and British migrants memorized plans from British mills.
Explanation:
During the War of 1812, American merchants had to face important economic adversities. Severe economic problems forced merchants of New England, such as Francis Cabot Lowell, to focus on manufacturing. Lowell had visited English mills in his trip to Great Britain. Afterwards, he arrived to Massachusetts with a clear memory of the plans for the technolgical textile machines he had observed in such visits, particularly the power loom, which worked as a replacement for individual hand weavers. Lowell persuaded some investors to create new mill towns and in 1813, they formed the Boston Manufacturing Company.
