Note 153 — Chapter IV · —The Movements Of Peoples In Their Geographical Significance

Even early maritime migrants did not keep their strains pure. The untried navigator sailing from island to headland, hugging the coast and putting ashore for water, came into contact with the natives. Cross currents of migration can be traced in Polynesian waters, where certain islands are nodal points which have given and received of races and culture through centuries of movement. The original white population of Uruguay differed widely from that of the other Spanish republics of South America. Its nucleus was a large immigration of Canary Islanders. These were descendants of Spaniards and the native Guanches of the Canaries, mingled also with Norman, Flemish and Moorish blood.153 The Norse on their way to Iceland may have picked up a Celtic element in the islands north of Scotland; but from the Faroe group onward they found only empty Iceland and Greenland. This was an exceptional experience. Early navigation, owing to its limitations, purposely restricted itself to the known. Men voyaged where men had voyaged before and were to be found. Journeys into the untenanted parts of the world were rare. However, the probable eastward expansion of the Eskimo along the Arctic rim of North America belongs in this class, so that this northern folk has suffered no modification from contact with others, except where Alaska approaches Asia.
