Gypsum, jip'sum, a mineral composed of lime, sulphur, and water. Like marl, it is used as a fertilizer. Gardeners buy it in sacks under the name of land plaster. It is used also in the manufacture of glass and porcelain. When heated to drive off moisture gypsum falls into a powder which has the quality of hardening or setting quickly if moistened again. The most noted gypsum quarries in the world are near Paris, whence the name, plaster of Paris. Plaster of Paris ground fine is much used in the arts. Paperhangers mend walls with it. Plasterers use it in the finer sorts of work. Mixed with glue it is used for stucco work in the execution of cornices, flowers, garlands, festoons, fruits, scrolls, and other ornamental designs. Extensive beds are worked in various countries of Europe, especially England and France. In America, Nova Scotia, Michigan, Kansas, and Iowa produce considerable quantities. Gypsum is produced also in New York, Virginia, South Dakota, California, Utah, and Wyoming. We make half a million dollars' worth of plaster of Paris a year and import half as much more. Gardeners and farmers buy about $50,000 worth of raw gypsum a year for fertilizers. See CARDIFF GIANT.
