WINDMILLS.

WINDMILLS.

The windmill is not yet superseded as an engine driven by the power of “unbought wind.” In Holland they are used for sawing timber, cutting tobacco, grinding trass and draining the polders. Holland has 10,000 windmills, each of which is said to drain 310 acres of land, at an average cost of one shilling an acre a year. In Norfolk they have been of inestimable service for works of drainage on the marshlands. A 15horsepower windmill erected at Faversham raised in ten months 21,000,000 gals, of water from a depth of 109 ft., saving 100 tons of coal. In the United States iron skeleton windmills were employed to pump water for domestic purposes long before they were applied to irrigation work. Pow erf ill mills have given farmers living on the plains a cheap source of power f.or various purposes, among other things to introduce town luxuries into their homes.
