The plateau lands are in the latitude of the great pine-forest belt that extends across the two continents. The forests of the Scandinavian peninsula are near the most densely peopled part of Europe, and they are also readily accessible. Moreover, the rugged surface offers unlimited water-power. As a result Norway and Sweden practically control the lumber-market of Europe, and their lumber products form one of the most important exports of the kingdom. Norway pine competes with California redwood in Australia. The "naval stores," tar and pitch, compete with those of Georgia and the Carolinas. The wood-pulp from this region is the chief supply of the paper-makers of Europe. Next to Russia, Sweden has the largest lumber-trade in Europe. The Mediterranean states are the chief buyers. The mineral products are a considerable source of income. Building stone is shipped to the nearby lowland countries. The famous Swedish manganese-iron ores, essential in steel manufacture, are shipped to the United States and Europe. For this purpose they compete with the ores of Spain and Cuba. The mines of the Gellivare iron district are probably the only iron-mines of consequence within the frigid zone. The ore is sent to German and British smelteries. The fisheries are the most important of Europe, and this fact has had a great influence on the history of the people. Centuries ago the people living about the _vigs_ or fjords of the west coast were compelled to depend almost wholly on the fisheries for their food-supplies. As a result they became the most famous sailors of the world. They established settlements in Iceland and Greenland; they also planted a colony in North America 500 years before the voyage of Columbus. Herring, salmon, and cod are the principal catch of the fisheries, and about four-fifths of the product is cured and exported to the Catholic European states and to South America. South of Kristiania farming is the principal industry. Much of the land is suitable for wheat-growing, but the productive area is so small that a considerable amount of bread-stuffs must be imported from the United States. On account of the high latitude the winters are too long and severe for any but the hardiest grains. Dairy products are commercially the most important output of the farms, and they find a ready market in the popular centres of Europe--London, Hamburg, Paris, and Berlin. The lumber, furniture, matches, fish, ores, and dairy products sold abroad do not pay for the bread-stuffs, coal, petroleum, clothing, and machinery. In part, this is made up by the carrying trade of Norwegian vessels; the rest of the deficit is more than met by the money which the throngs of tourists spend during the summer months. The United States buys from these countries fish and ores to the amount of about three million dollars a year; it sells them cotton, petroleum, bread-stuffs, and machinery to the amount of about twelve million dollars.
