On the 28th of September the _Vega's_ progress for the year was arrested by her being frozen in for the winter on the eastern side of Kolyuchin Bay in the northernmost part of Bering Strait, only six miles of ice barring the way round Cape Serdze Kamen into the open sea. During her detention of two hundred and sixty-four days the scientific investigations of many kinds that were undertaken were of lasting importance, as they had been throughout, and when she was released on the 18th of July, 1879, to come home by way of Yokohama, the collections and records she brought with her were simply enormous. No better work with greater results was done by any Arctic expedition than during this successful voyage, which was too well managed to have much adventure. For it Nordenskiöld very justly claimed the reward of twenty-five thousand guilders offered in 1596 by the States-General of Holland, the endeavour to win which sent out Van Heemskerck, Barents, and Rijp. [Illustration: ADOLF ERIK NORDENSKIÖLD] We have seen how the Dutchmen built their house at Ice Haven mainly of the driftwood from the Siberian rivers. Similar wood from probably the same source is found on the shores of Greenland and of almost all the northerly islands of the Arctic Ocean. Further, the Greenland flora includes a series of Siberian plants apparently from seeds drifted there by some current. Not only do trees and seeds travel by water from Asia westward to America; at Godthaab, for instance, on the western coast of Greenland, there was found a throwing-stick of a shape and ornamentation used only by the Alaskan Eskimos; and three years after the foundering of the _Jeannette_ to the north of the New Siberian Islands there were found on the south-west coast of Greenland a number of articles in the drift-ice that must have come from the sunken vessel. For these and other reasons it seemed clear to Fridtjof Nansen that a current flowed at some point between the Pole and Franz Josef Land from the Siberian Arctic Sea to the Greenland coast, and so he set to work to organise his daring expedition to strike this current well to the eastward, trusting to its mercies to take him to or near the Pole.
