    The horizontal-wheel mill (sometimes called a Norse or Greek mill) also required little auxiliary construction but it was suited for grinding because the upper millstone was fixed upon the vertical shaft. The mill however could only be used where the current flow was suitable for grinding. The geared vertical-wheel mill was more versatile.
