HERNOSAND or WESTER NORRLAND, a län of Sweden, lying chiefly between N. Lat. 62. and 64. and E. Long. 15. and 19., and bounded on the N. by Umea, W. by Östersund, S. by Gefle, and E. by the Gulf of Bothnia. Its greatest length along the coast is about 140 miles, and its breadth varies from about 20 to 100. Area about 9500 square miles. Hernosand presents an extremely varied surface. Its elevations, frequently steep and rocky, and generally for the most part covered with trees, its deep and narrow valleys, with rapid and winding rivers, and its fine mountain lakes, all conspire to render it superior to most if not to all the other läns in Sweden. The chief products, besides corn, which is scantily grown, are deals, tar, and some iron. The principal branch of industry is the manufacture of linen, which is extensively carried on, the spinning being done by both sexes during the long winter nights. The rearing of cattle receives some attention. Pop. (1850) 99,558.
