About 23 per cent. of the area of Prussia is under forests. Only a little over one-hall of the total forest area is in private hands, and private ownership is constantly declining. The remainder is held by the state and local governments, the State controlling about two-thirds; of the area. The largest forests are in Brandenburs% and the Rhine Province, while 1lohenz(711ern and Schleswig-Holstein are almost entirely devoid of woods. Nearly one-third of the forest area is under coniferous trees, the remainder being un der deciduous trees; the former predominate in the north. The Prussian Government derives a revenue of about $20,0110.000 a year from the for est industry. See (iERNIAN Y. paragraphs on Agri culture, Ntock-Breuding, and Forestry.
3IA cUFACT RES. The increase from 1552 to 1595 in the number of persons employed in the Prussian manufacturing industries was over 33 per cent. The textile industries thrive in Rhen ish Prussia, noted for its cotton spinning and weaving. and for its woolen and silk products, and Silesia, known both for its cotton and linen manufactures. Aachen (Aix-la-Chapelle) and its district are a great seat of the woolen manu facture. and Krefeld and Elberfeld are noted centres of the silk industry. Berlin and Rhenish Prussia and some of the largest cities in other sections of Prussia turn out most of the ma chinery and meta] work. The iron and steel in
dustry is on a vast scale. and is chiefly eentred in the coal field of the Ruhr. Large amounts of the pig iron and steel made in that region are sent to machine shops in various parts of the country for conversion into a great variety of articles. The most famous iron and steel works are at Essen. Ship-building is a very important and growing industry in the cities of Kiel, Dan zig. Stettin, and Elbing. tar and wagon works centre largely in the eastern cities of Breslau and besides Cologne, Diisseldorf. and Giirlitz. Glass and porcelain ware and pottery are produced in Rhenish Prussia, Silesia, and Saxony: the same is true of paper. The chem ical industry is especially important in the Rhine cities. and is also prominent in Berlin. See CER MAN Y, paragraph on Manufactures, and the arti cles On the provinces and leading cities.
