The early mills had horizontal paddle wheels, an arrangement which later became known as the “Norse wheel”, as many were found in Scandinavia. The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the “runner stone”. The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary “bed”, a stone of a similar size and shape. This simple arrangement required no gears, but had the disadvantage that the speed of rotation of the stone was dependent on the volume and flow of water available and was, therefore, only suitable for use in mountainous regions with fast-flowing streams. This dependence on the volume and speed of flow of the water also meant that the speed of rotation of the stone was highly variable and the optimum grinding speed could not always be maintained.
