[1][2] In later times, the people who farmed the inhospitable countryside made a living by weaving - mostly wool from their own sheep - using a handloom, and the early mills were designed to help them with the supply of yarn and the provision of ancillary services.
These moorland mills held their own for more than half a century against their big-town rivals, many finding a niche for themselves, as mainline competition increased, by developing as cotton-waste spinners.
This involved recycling the inner core of yarn cops, which had been stiffened in manufacture by the application of starch paste to avoid the need for separate wooden bobbins.
By the 1870s the mills were struggling to compete against the steam-powered economics of their massive rivals in the nearby towns and, before the turn of the century, they had all but vanished.
Many of the former mills, lodges and a solitary chimney seen by air, along with other industrial workings such as Weirs and Dykes, are still evident today.
