The pure Nordic race is at present clustered around the shores of the Baltic and North Seas from which it has spread west and south and east fading off gradually into the two preceding races. The centre of its greatest purity is now in Sweden and there is no doubt that at first the Scandinavian Peninsula and later, also, the immediately adjoining shores of the Baltic were the centres of radiation of the Teutonic or Scandinavian branch of this race. The population of Scandinavia has been composed of this Nordic subspecies from the commencement of Neolithic times and Sweden to-day represents one of the few countries which has never been overwhelmed by foreign conquest and in which there has been but a single racial type from the beginning. This nation is unique in its unity of race, language, religion and social ideals. Southern Scandinavia only became fit for human habitation on the retreat of the glaciers about twelve thousand years ago and apparently was immediately occupied by the Nordic race. This is one of the few geological dates which is absolute and not relative. It rests on a most interesting series of computations made by Baron DeGeer, based on an actual count of the laminated deposits of clay laid down annually by the retreating glaciers, each layer representing the summer deposit of the subglacial stream. The Nordics first appear at the close of the Paleolithic along the coasts of the Baltic. The earliest industry discovered in this region, named the Maglemose and found in Denmark and elsewhere around the Baltic, is probably the culture of the Proto-Teutonic branch of the Nordic race. No human remains in connection therewith have been found. The vigor and power of the Nordic race as a whole is such that it could not have been evolved in so restricted an area as southern Sweden although its Teutonic or Scandinavian section did develop there in comparative isolation. The Nordics must have had a larger field for their specialization and a longer period for their evolution than is afforded by the limited time which has elapsed since Sweden became habitable. For the development of so marked a type there is required a continental area isolated and protected for long ages from the intrusion of other races. The climatic conditions must have been such as to impose a rigid elimination of defectives through the agency of hard winters and the necessity of industry and foresight in providing the year’s food, clothing and shelter during the short summer. Such demands on energy if long continued would produce a strong, virile and self-contained race which would inevitably overwhelm in battle nations whose weaker elements had not been purged by the conditions of an equally severe environment.
