Mill′stone-dress.
（Grinding.) a. The arrangement and disposition of the furrows in the face of a millstone. b. The draft given to the furrows. The object of the various kinds of dressing is to secure the proper proportional quantity of material on the stone from the eye to the skirt. The kinds of dress are known as the quarter dress and the circular dress. In the former the face is divided up into a number of sectors, each of which is known as a quarter, and has its own set of furrows. The advance edge of a furrow is the lading edge, the other is the trailing edge. See grinding-mill. The querns of the Keltic and Roman inhabitants of Britain had notches, forming a dress. Fig. 3156 is a collection of views of different millstones, which will not be described at length. The upper examples are quarter dress; then follow specimens of radial-and-circular dress, then a number of curved and circular systems. In addition to the features involving direction are others, such as openings in the bed or runner, forming pockets, or for ventilation, or to allow escape of fine flour. Natcher's patent of 1858 is for ruling lines with a diamond on the land of the stone to give it a cutting quality. In corn and feed mills with serrated iron plates for grinding, the dress is different, as shown in Fig. 3157. Many of these plates are frustums of cones or conoids.
