We must not, however, forget that the sagamen in whose memories alone these narratives were preserved at least a hundred and fifty years, and not unlikely for more than three hundred, were professional narrators of events. It was their office and duty to transmit to others what they had themselves received. Their professional character was in some degree a guarantee for the preservation of the truth. But nevertheless it was impossible through a long series of oral narrations, that errors should not creep in; that the memory of some of them should not fail at times; and if it did fail there was no authority or standard by which their errors could be corrected. Moreover it is probable that variations were purposely introduced here and there, in obedience to the sagaman's conceptions of an improved style and a better taste. What variations took place through the failure of the memory or the conceit of the sagamen, whether few or many, whether trivial or important, can never be determined. It is therefore obvious that our interpretation of minor particulars in the sagas cannot be critical, and any nicely exact meaning, any absolute certainty, cannot be successfully maintained, since an inevitable doubt, never to be removed, overshadows these minor particulars. We may state, therefore, without hesitation, that the narratives of the sagas are to be accepted only in their general outlines and prominent features. So far we find solid ground. If we advance farther we tread upon quicksands, and are not sure of our foothold. The question here naturally arises, viz., If in minor particulars the sagas cannot be fully relied upon, to what extent can we identify the countries discovered, and the places visited by the Northmen? In answer to this very proper inquiry, I observe that, according to the narrative of the sagas, and the interpretation of Scandinavian scholars, the first country that the explorers discovered after leaving Greenland answers in its general features to Newfoundland, with its sterile soil, its rocky surface, and its mountains in the back-ground. The second answers to Nova Scotia, with its heavy forests, its low, level coast, and its white, sandy cliffs and beaches. The third answers to New England in temperature, climate, productions of the soil, the flat, undulating surface of the country, and its apparent distance from Greenland, the base or starting-point from which these voyages of discovery were made.
