KLAUSTHALL *s a town of Germany, in the principa lity of Grubenhagen, and the kingdom of Hanover. It tains two churches, an orphan's hospital, a mint for coining money, and a small garrison. The town is open and regu larly built, and derives its importance from the mines (lithe Hartz mountains in its vicinity. It is situated 1374 Paris feet higher than Gottingen ; and the lowest point of the mine ot Roschofer is only 248 of these feet below the level of the same town. The richest mines here are the Caro line, which is 630 feet deep ; and the Dorothea, which is 612 feet. The Georgestollen is a remarkable conduit, near ly seven miles long, and 930 feet deep. It was begun in 1777 for the purpose of carrying off the subterraneous wa ter of the mines. The Caroline none, in the year 1780, produced every three months 54 crowns at each part tit the mine, and the Dorothea mine 04. This is a smaller pro duce than when the Dorothea mine yielded, in 67 successive quarters, 110 crowns. In the year 1735, there
were coined at Kiausthall every week 600 marks of silver, at the rate of 12 crowns the mark, which amounted to 374,000 crowns a year. At Ludwiger Rechenhaus is a very curious collection of all the machines either employed in mining, or that have been prepared for that purpose. Bo senhof is the Vauxhall of Klausthall and Zellerfeld. New Klausthall is the small town of Gitielde, which has seve ral forges, and is remarkable as containing the ruins of Stauflenbourg, a chateau built by Henry Oiseleur; and also the place called Heinrichswinkel, where Henry was occupied in catching birds when the German deputies came to offer him the imperial crown. Population 8000. An account of the remarkable conduit called Georgestol len will be found in work by M. Gotthard, written ex pressly on the subject, and entitled, Authentisch Beach reibung -vom des Ceorgestollens. Wernigerode, 1801.
