Explanation:

The geographical condition of New England allowed them to indulge in manufacturing spinning mills in America. The availability of water power, wood, and raw cotton helped mills to come up in New England. Labour in the colonies brought from England and Africa via crossing the Atlantic Ocean.  Water-powered mills eventually paved the way for showing the benefits of machinery and mechanical power. By 1700 there were about 70 water-powered mills in New England.
