Nansen’s expedition lifted the veil of mystery from a large portion of the Arctic regions. It proved that no land existed over the long zigzag route traversed by the _Fram_ from the New Siberian Islands to a point north of Spitzbergen within 350 miles of the Pole, nor over the long sledge-route traversed by Nansen and Johansen. It discovered that the Polar Sea, instead of being shallow as hitherto supposed, is a deep basin, exceeding in many places 11000 feet. The _Fram_ drifted very near the route sketched by Nansen before the expedition set out, and although Nansen had to admit that the real force which caused the drift was the wind—an opinion previously formed by De Long from the drift of the _Jeannette_—this did not alter the final result. The drift of the _Fram_ also forcibly proves that the great mass of ice in the Polar Sea is in a constant state of movement. It was found that in the sea north of Siberia the prevailing winds were south-easterly or easterly, and therefore the drift was towards the north-west or west. On the other hand, to the north of Spitzbergen the winds are north-easterly, and the drift is to the south-west. The manner in which the _Fram_ drifted also allows speculations to be made as to the likelihood of the existence of land to the north of the _Fram’s_ track. It was found that with a southerly wind the ice moved easily towards the north. This is in favour of the view that no land exists within a considerable distance to the north. The depth of water and the absence of bears during 1895 also favour this view. There is a greater probability that land may exist north of Greenland or north of Grinnell Land.[1] The _Fram_ began to drift to the south when it reached the neighbourhood of 66° E. longitude, or to the north of Franz-Josef Land. The latitude was then 85° 55.5′. It is probable, however, that the _Fram_ was now within the direct influence of the drift which constantly passes down the east coast of Greenland, and that the drift to the south was not due to land towards the north or west. More ice is formed in the Polar Sea during the long winter than is melted during the short summer, and the surplus must find an outlet into the warmer water of the south. The ice of the Polar Sea may be compared to the ice of a mighty glacier: the surplus of both moves on until it finds an outlet, and moves in the path of least resistance. The chief and almost only outlet from the Polar Sea is between Greenland and Norway. A comparatively small amount of ice finds its way through Robeson Channel or Behring Strait. The drift of the _Jeannette_ proves that from Behring Strait the set of the ice is towards the west and north-west. Between the longitude of Behring Strait and the longitude of the north-east of Greenland there must somewhere be a dividing-line where it will be easier for the ice to find its way east round the north of Greenland than westward over the great extent of Polar Sea.
