Actually Akenaton not all meal mills were water fed on some islands where there was not a burn or river they did have wind or horse powered mills.

Quite a few of the bigger farms on Orkney still have a round building at one end which is where the horse was walked round powering the mill.

On Papa Westray on Dauvits uncles far you can still see what looks like a small plinth which was the post for a small windmill.

Will thoroughly enjoyed the video.

You have to go a fair bit down the page before you see the remains of the post mill on uncle john's farm
