The United States of America must be regarded racially as a European colony and owing to current ignorance of the physical bases of race, one often hears the statement made that native Americans of Colonial ancestry are of mixed ethnic origin. This is not true. At the time of the Revolutionary War the settlers in the thirteen Colonies were overwhelmingly Nordic, a very large majority being Anglo-Saxon in the most limited meaning of that term. The New England settlers in particular came from those counties of England where the blood was almost purely Saxon, Anglian, Norse and Dane. The date of their migration was earlier than the resurgence of the Mediterranean type that has so greatly expanded in England during the last century with the growth of manufacturing towns. New England during Colonial times and long afterward was far more Nordic than old England; that is, it contained a smaller percentage of small, Pre-Nordic brunets. Any one familiar with the native New Englander knows the clean cut face, the high stature and the prevalence of gray and blue eyes and light brown hair and recognizes that the brunet element is less noticeable there than in the South. The Southern States were populated also by Englishmen of the purest Nordic type but there is to-day, except among the mountains, an appreciably larger amount of brunet types than in the North. Virginia is in the same latitude as North Africa and south of this line no blonds have ever been able to survive in full vigor, chiefly because the actinic rays of the sun are the same regardless of other climatic conditions. These rays beat heavily on the Nordic race and disturb their nervous system, wherever the white man ventures too far from the cold and foggy North. The remaining Colonial elements, the Holland Dutch and the Palatine Germans, who came over in small numbers to New York and Pennsylvania, were also largely Nordic, while many of the French Huguenots who escaped to America were drawn from the same racial element in France. The Scotch-Irish, who were numerous on the frontier of the middle Colonies were, of course, of pure Scotch and English blood, although they had resided in Ireland for two or three generations. They were quite free from admixture with the earlier Irish, from whom they were cut off socially by bitter religious antagonism and they are not to be considered as “Irish” in any sense. There was no important immigration of other elements until the middle of the nineteenth century when Irish Catholic and German immigrants appear for the first time upon the scene. The Nordic blood was kept pure in the Colonies because at that time among Protestant peoples there was a strong race feeling, as a result of which half-breeds between the white man and any native type were regarded as natives and not as white men.
