The furthest southern point reached by Karlsefni is a question of great interest. In the Flatey book Leif is made to say that on the shortest day the sun was above the horizon from _Eyktarstad_ to _Dagmalastad_. We thus obtain rough data for ascertaining the latitude of Vinland. The Icelanders ascertained the various times of the day by selecting conspicuous marks round their houses, and noting the course of the sun with relation to them. Names were given to the positions the sun occupied at certain times of the day, and the Norsemen were thus, from long practice, very accurate in assigning the points of the compass at which the sun rose or set. The _Eyktarstad_ is clearly defined in an ancient Icelandic book called _Kristinretter_. If the S.W. octant be divided into thirds, the S.W. point being in the centre, it is _Eyktarstad_ when the sun has traversed two-thirds. This gives the amplitude of the sun, when it set on the shortest day at Vinland, W. 37 degrees 30′ S. The sun’s declination in A.D. 1005 was 23 degrees 34′ 30″ N. With these data we find the latitude of the point of observation on Vinland to have been a little south of 49 degrees S., which would be in Bona Vista Bay, on the east coast of Newfoundland[14]. Karlsefni passed three winters in Vinland and here, in the year 1007, his wife Gudrid bore him a son who was named Snorri. From this American-born child was descended the Lagman Hauk, the author of the Hauk book, and many Danish families, including that of Thorwaldsen, the famous sculptor. After the third winter Karlsefni and his followers sailed away from Vinland on their return. The ship of Bjarni was driven out to sea in a gale, and all perished except one boat’s crew which is said to have reached Dublin. When the ship began to sink it was found that the boat would only hold half the crew. So they cast lots, and it fell to the lot of Bjarni to go in the boat. When the lucky ones were all in the boat, an Icelandic youth, who was left in the ship, cried out “Dost thou intend, Bjarni, to forsake me?” “It must be even so,” answered Bjarni. “Not such was the promise thou gavest my father,” replied the youth. “So be it, it shall not rest thus,” answered Bjarni. “Do thou come hither and I will go to the ship, for I can see thou art eager for thy life.” So he went on board again and the youth got into the boat. Karlsefni and Gudrid, with their little son, arrived safely in Greenland, and remained at Brattahlid during the following winter, with Erik and his son Leif. Then they sailed to Iceland and lived to a good old age at Reynistadr in the north, a little south of Skaga-fjord. Their son Snorri succeeded them, and, as has been already said, was the ancestor of many great people in Iceland and Denmark[15].
