[Footnote 210: Storm, "Studies on the Vinland Voyages," _Memoires de la societe royale des antiquaires du Nord_, Copenhagen, 1888, p. 351. The limit of the vine at this latitude is some distance inland; near the shore the limit is a little farther south, and in Newfoundland it does not grow at all. Id. p. 308.] [Footnote 211: The attempt of Dr. Kohl (_Maine Hist. Soc._, New Series, vol. i.) to connect the voyage of Thorfinn with the coast of Maine seems to be successfully refuted by De Costa, _Northmen in Maine_, etc., Albany, 1870.] [Sidenote: Length of the winter day.] We may now observe that, while it is idle to attempt to determine accurately the length of the winter day, as given in our chronicles, nevertheless since that length attracted the attention of the voyagers, as something remarkable, it may fairly be supposed to indicate a latitude lower than they were accustomed to reach in their trading voyages in Europe. Such a latitude as that of Dublin, which lies opposite Labrador, would have presented no novelty to them, for voyages of Icelanders to their kinsmen in Dublin, and in Rouen as well, were common enough. Halifax lies about opposite Bordeaux, and Boston a little south of opposite Cape Finisterre, in Spain, so that either of these latitudes would satisfy the conditions of the case; either would show a longer winter day than Rouen, which was about the southern limit of ordinary trading voyages from Iceland. At all events, the length of day indicates for Vinland a latitude south of Cape Breton. [Sidenote: Indian corn.]
