text: Horse power (1780–1790) The earliest cotton mills in the United States were horse-powered. The first mill to use this method was the Beverly Cotton Manufactory, built in Beverly, Massachusetts. It was started on 18 August 1788 by entrepreneur John Cabot and brothers. It was operated in joint by Moses Brown, Israel Thorndike, Joshua Fisher, Henry Higginson, and Deborah Higginson Cabot. The Salem Mercury reported that in April 1788 the equipment for the mill was complete, consisting of a spinning jenny, a carding machine, warping machine, and other tools. That same year the mill's location was finalized and built in the rural outsets of North Beverly. The location had the presence of natural water, but it was cited the water was used for upkeep of the horses and cleaning of equipment, and not for mass-production.
  Much of the internal designs of the Beverly mill were hidden due to concerns of competitors stealing designs. The beginning efforts were all researched behind closed doors, even to the point that the owners of the mill set up milling equipment on their estates to experiment with the process. There were no published articles describing exactly how their process worked in detail. Additionally, the mill's horse-powered technology was quickly dwarfed by new water-powered methods.

  Following the creation of the United States, an engineer who had worked as an apprentice to Arkwright's partner Jedediah Strutt evaded the ban.  In 1789, Samuel Slater took his skills in designing and constructing factories to New England, and he was soon engaged in reproducing the textile mills that helped America with its own industrial revolution.
