The Dighton Rock runes erelong fell into woeful discredit; and as for the Newport Round Tower, it has been identified as “The Old Stone Mill” built there by Governor Benedict Arnold, who removed from Providence to Newport in 1653. Though therefore no longer to be accredited to the Northmen, it is of very respectable architectural antiquity, according to New World reckoning. Nevertheless, in spite of such failure of all confirmatory evidence, the general summary of results was presented by Professor Rafn in such absolute terms, and the geographical details of the assumed localities were so confidently accredited by the members of the Rhode Island Historical Society, that his conclusions were accepted as a whole without cavil. In reality, however, when we revert to the evidence from which such definite results were derived, it proves vague, if not illusory. The voyagers crossed over from Greenland to Helluland, which we may assume without hesitation to have been the inhospitable coast of Labrador. They then pursued a south-western course, in a voyage in all of four days, subdivided into two nearly equal parts, until they landed on a coast where wild grapes grew, and which accordingly they named the Land of the Vine. To Icelandic or Greenland voyagers, the vine, with its clusters of grapes, however unpalatable, could not fail to prove an object of special note. But there is no need to prolong the four days’ run, and land the explorers beyond Cape Cod, in order to find the wild grape. It grows in sheltered localities in Nova Scotia; and so in no degree conflicts with the later deductions based on the same astronomical evidence of the length of the shortest day, which have induced subsequent investigators to adopt conclusions much more nearly approximating to those suggested by the poet Montgomery fully sixteen years before the issue of Professor Rafn’s learned quarto from the Copenhagen press.
