"If you wish to know what men seek in this land [the Arctic regions], or why men journey thither in so great danger of their lives, then it is the threefold nature of man that draws him thither. One part of him is emulation and desire of fame, for it is a man's nature to go where there is likelihood of great danger, and to make himself famous thereby. Another part is the desire of knowledge, for it is man's nature to wish to know and see those parts of which he has heard, and to find out whether they are as it was told him or not. The third part is the desire of gain, seeing that men seek after riches in every place where they learn that profit is to be had, even though there is great danger in it." And, indeed, it may well be admitted that the factors which have helped to make the modern world are mainly a desire for fame, a desire for knowledge, and a desire for riches; and woe betide the nation that forgets the first and second of these factors, and loses its soul in concentration upon the last of them. II During the years succeeding Nansen's expedition the desire to reach the North Pole itself took possession of the minds of many brave men. Bit by bit the Arctic regions had been mapped out; gradually the obstacles that maintained the Pole in its splendid isolation were being overcome. Some years were to pass before its mysteries were unveiled, but in those years there was an almost continuous effort to probe those mysteries. Nansen had discovered beyond any doubt that the Pole lay in an ice-covered sea, an inhospitable place enough; but this fact did not prevent explorers from wanting actually to locate it, and in 1900 the Duke of the Abruzzi tried to reach it by way of Franz-Josef Land. Owing to a frost-bitten hand, the Duke could not take part in the main journey of his expedition, and so Captain Cagni commanded it. The Pole withstood this effort, but Cagni did succeed in reaching 86° 33' N., and thus beat Nansen's record for "farthest north." Previous to the Abruzzi expedition, Robert Peary had launched his first great attack upon the Pole. This expedition lasted for four years--1898 to 1902--but Peary encountered such dense packs of ice, which blocked his way to the Polar Ocean, that he failed in his main object.
