We need a land-locked bay, largely barred by shoals, guarded on one side of the entrance by a cape facing north, and on the other by an island, or something which might pass for one on a hasty visit. Into this bay a river must flow, which expands into a lake-like widening near its mouth, and then narrows, so as to divide the lake from the bay. This river must flow in from the north, as the Skrælings who visited the camp are said to have come from the south. A minor point, which is not so reliable as the remainder, is the mention of salmon in the river, which is included in the Flatey Book description. Now it is manifestly not every river-estuary or land-locked bay which will conform to such a description in all, or even in nearly all, particulars. If therefore we find, in a suitable part of the American coast, a place which fulfils every one of these requirements, we may make our identification with something approaching certainty. Now if the entrance of Long Island Sound be accepted as the site of the Straumsfjord base, the furthest limit of the exploration, at Hóp, can be made to fit the requirements of the story in a really remarkable way. I am convinced that it is a mistake to look for all the places mentioned in Karlsefni’s voyage within the restricted limits which seem to have contented other students of the subject. It seems to me illogical, when we hear of voyages of two or three days covering very considerable distances, to suppose when the saga says, ‘they sailed a long time,’ that we can be content to look for all the places mentioned in the course of a year’s exploration within a few hours’ sail of one another. It took a long time to sail past Furdustrands, and it was a long way from Straumsfjord to Hóp. The latter place is therefore to be sought about as far on from Straumsfjord as Straumsfjord was from Keelness. One has, moreover, to bear in mind, in searching for likely landfalls, that it is by no means every inlet which is likely to attract the notice of sailors on a coasting voyage. Openings which lie directly in their course, of which the situation selected for Straumsfjord is an example, are really far more likely to be explored. Now, about as far to the west of the entrance to Long Island Sound as Cape Cod lies to the east of it, the direction of the coast-line undergoes an abrupt change. And exactly in the angle formed by this change of direction is a bay, fulfilling all the requirements of Hóp. It is a land-locked estuary, largely barred by shoals, with a river running into it from the north, which widens into a lake among hills a short distance from the mouth. The approach involves a westerly course between a cape running north and an island. This is the bay or estuary of the Hudson River, constituting the modern approach to New York.
