Molding-milL A planing-mill for shaping tim-ber. .See JIoLniNO-MACHiXE, 1. Molding-planes. Joiners planes for makingnnldiugs, and having various patterns, nr concaveand convex soles to form parts of moldings. Suchas liollows and rounds. Match-planes. plow. Used for molding or forming ridges, strikingwater-courses, or hOling-up potatoes ; so constructedas to thoroughly turn the soil, burying the suiface andbringing up the bottom. That shown is made en-tirely of iron, having a trussed beam and front wheel,and may be used for splitting ridges ; the breast islaterally expansible, and the penetration of the shareis regulated by the draft-chain at the clevis. Molding-^a-wr. One or a number of circularsaws for bloi;king out strips for ornamental mold-ings. The strips are fed repeatedly to the saw at differ-ent angles, and the general outline of the api)roximated. The work is generally com-pleted by revolving planes. Mole. 1. (^Uusbandnj.) A cyl
