[223] Professor Rafn in, what seems to the author, his needless anxiety to fix the locality of the White-man's land in America, says that, as this part of the manuscript is difficult to decipher, the original letters _may_ have got changed, and vi inserted instead of xx, or xi, which numerals would afford time for the voyager to reach the coast of America, in the vicinity of Florida. Smith in his _Dialogues_, has even gone so far as to _suppress_ the term _six_ altogether, and substitutes, "by a number of days sail unknown." This is simply trifling with the subject. In _Grönland's Historiske Mindesmærker_, chiefly the work of Finn Magnussen, no question is raised on this point. The various versions all give the number six, which limits the voyage to the vicinity of the Azores. Schöning, to whom we are so largely indebted for the best edition of Heimskringla, lays the scene of Marson's adventure at those islands, and suggests that they may at that time have covered a larger extent of territory than the present, and that they may have suffered from earthquakes and floods, adding, "It is likely, and all circumstances show, that the said land has been a piece of North America." This is a bold, though not very unreasonable hypothesis, especially as the volcanic character of the islands is well known. In 1808, a volcano rose to the height of 3,500 feet. Yet Schöning's suggestion is not needed. The fact that the islands were not inhabited when discovered by the Portuguese does not, however, settle anything against Schöning, because in the course of five hundred years, the people might either have migrated, or been swept away by pestilence. _Grönland's Historiske Mindesmærker_, (vol. I, p. 150), says simply, that "It is _thought_ that he (Are Marson) ended his days in America, or at all events in one of the larger islands of the west. Some think that it was one of the Azore islands."
