A fantail, the fan of which when seen by a viewer having his back to the wind, turns anti-clockwise. The wind usually operates the fantail when blowing obliquely on to it. The fan will .reverse direction when the wind blows on to its opposite face, but will still be seen to turn anti-clockwise by a viewer with his back to the wind.
Millstones, the runner stone of which is seen (in a conventional windmill or watermill layout) to rotate anti-clockwise when seen from above. With millstones DRESSED with HARP pattern furrows, a MASTER FURROW, when viewed from one edge of the stone, passes from the left-hand side of the EYE (DRAFT CIRCLE) to the edge of the stone towards the viewer. The minor furrows lie parallel to it on its left-hand side. With SICKLE DRESS and other variants of curved furrows, the furrows similarly pass generally from the left hand side of the draft circle towards the viewer. Both stones of the pair usually carry an identical Dress.
