“ The intricate archipelago of islets and granite and limestone rocks in the Bothnian gulf renders the navigation extremely dangerous. The lakes occupy about 12 per cent. of the area, the marshes 20 per cent., so that Finland is more abundantly supplied with water than any other country in the world. The land appears to have been formerly a sea-bed, which was gradually elevated and is still rising at the rate of about 3.4 feet on the Gulf of Bothnia, and 1.9 feet on the Gulf of Finland in a hundred years. ”
