Officially known as the Netherlands, a small maritime country of Western Europe, bordered on its N. and W. by the German Ocean, and having Prussia on its E. and Belgium to the S.; its area, somewhat less than one-fourth the size of England and Wales, comprises, besides the mainland, two island groups, one in the N. and one in the S.; its flat surface in great part lies below the level of the sea, and where there are no natural sandhills is protected from inundation by enormous dykes, 365 ft. thick, forming excellent carriage-ways along the coast; much of the soil has been reclaimed by draining lakes and by pushing back the sea walls, the size of the country having been increased by one-half since 1833; canals traverse the country in all directions, and form with the shallow lakes and the great rivers a complete system of waterways. The climate is for the most part similar to that of England, but greater extremes of heat and cold are experienced. Farming is the staple industry, although a considerable portion of the land is still unfit for cultivation; butter and cheese are the most valuable products, and are largely exported; the fisheries, coast and deep sea, are also of much importance; manufactures are retarded by the want of coal, but the wind is made to supply the motive power, by means of windmills, to flourishing textile factories (cotton, woollen, and silk), gin distilleries, pottery works, margarine and cocoa factories, etc. Holland no longer is the premier shipping country of Europe, a position it held in the 17th century, but it still maintains a busy carrying trade with all parts of the world, especially with its many rich colonies in the East and West Indies, which comprise an area 64 times larger than Holland itself. The government is a limited monarchy; the executive power is vested in the crown and the legislation in the States-General, an assembly consisting of two chambers, the one elected (for four years) by direct suffrage, the other (for nine years) by provincial councils. Primary education is free, but not compulsory. Religion is not established, but about two-thirds of the people are Protestants, the remainder Roman Catholics. The birth of Holland as an independent European power took place in the 16th century, when, after an heroic and protracted struggle, it freed itself from the yoke of Spain, then the most powerful nation in the world.
