We must turn aside for a moment from these efforts to get farther and farther north, to mention the exploits of that distinguished Swedish explorer, Adolf Erik Nordenskiöld. As early as 1873 Nordenskiöld began to think that the North-East Passage by the Siberian coast might, when found, prove to be of great commercial value, and after some preliminary expeditions he, in 1878, set out in the _Vega_ on his great voyage, and in August the ship passed Cape Chelyuskin, the most northerly point of the Old World. By September, however, the _Vega_, when very near to the completion of her task, was so surrounded by ice that she could proceed no farther, and for ten months she was held a prisoner. Not until the following July was the Vega free to resume her voyage, and shortly afterwards she rounded East Cape, and saluted "the easternmost coast of Asia in honour of the completing of the North-East Passage." Nordenskiöld, both as an explorer and as a man of science, has left the world greatly in his debt, and it has been well said that "when he died, a vast amount of knowledge died with him." Nordenskiöld's name, like Fridtjof Nansen's, is intimately connected with exploratory work in Greenland. Nansen was born in 1861, and he was only twenty-seven years of age when his devotion to discovery led him to make an expedition on lines that were as courageous as they were original. Up to this date, 1888, the recognized method employed in Polar exploratory work had been to establish a base where stores were placed, and from this base to march as far as possible in various directions. But when Nansen determined to cross Greenland from east to west, he paid no attention to recognized methods. With five companions he, in June, 1888, was taken in the _Jason_ to the ice's edge on the east coast of Greenland, and there the explorers, hoping shortly to reach land, took to their boats. Some time, however, passed before they could make a landing, but eventually a suitable place was found, and then they began their great march. With no base to which they could return, the party had literally taken their lives into their hands, for failure almost certainly meant death. Starting on 22nd August, the party, four days later, had mounted to a height of 6,000 feet, and by the middle of September had reached the summit (8,250 feet). Eventually the explorers managed to reach the Danish settlement at Godthaab, and in the following year returned to Norway. It was a fine effort, fruitful alike in geographical discovery and in meteorological results; and, famous as Nansen's name subsequently and deservedly became, by no means his least claim to honour is derived from this great march across Greenland.
