Much was done, it appears, in the way of exploring the extreme northern portions of the country known as _Nordrsetur_. In the year 1266, a voyage was made under the auspices of some of the priests, and the adventurers penetrated north of Lancaster sound, reaching about the same latitude that was attained by Parry in 1827. This expedition was of sufficient importance to justify some notice of it here. The account is found in _Antiquitates Americanæ_ (p. 269), and it sets out with the statement that the narrative of the expedition was sent by Haldor, a priest, to Arnald, the chaplain of King Magnus in Norway. They sailed out of Kroksfiardarheidi in an open boat, and met with southerly winds and thick weather, which forced them to let the boat drive before the wind. When the weather cleared, they saw a number of islands, together with whales and seals and bears. They made their way into the most distant portion of the sea, and saw glaciers south of them as far as the eye could reach. They also saw indications of the natives, who were called Skrællings, but did not land, on account of the number of the bears. They therefore put about, and laid their course southward for nearly three days, finding more islands, with traces of the natives. They saw a mountain which they call Snæfell, and on St. James day, July 25, they had a severe weather, being obliged to row much and very hard. It froze during the night in that region, but the sun was above the horizon both day and night. When the sun was on the southern meridian, and a man lay down crosswise in a six-oared boat, the shadow of the gunwale towards the sun would reach as far as his feet, which, of course, indicates that the sun was very low. Afterwards they all returned in safety to Gardar.[39] Rafn fixes the position of the point attained by the expedition in the parallel of 75° 46´. Such an achievement at that day indicates a degree of boldness quite surprising. THE DECLINE OF GREENLAND. Of the reality and importance of the Greenland colony there exists no doubt, notwithstanding the records are so meagre and fragmentary.[40] It maintained its connection with the mother countries for a period of no less than four hundred years; yet it finally disappeared and was almost forgotten. The causes which led to the suspension of communication were doubtless various, though it is difficult to account for the utter extinction of the colony, which does not appear ever to have been in much danger from the Skrællings. On one occasion, in 1349 or later, the natives attacked the western settlement, it is said, and killed eighteen Greenlanders of Icelandic lineage, carrying away two boys captives.
