Our problem of adventurous navigation in the nineteenth century has been the discovery of the North and South Poles. We have succeeded in our purpose, but not without much sacrifice of treasure and men and much suffering. For many people in our time the finding of the Poles has seemed merely a quixotic undertaking, and, as a matter of fact, there has been no great practical purpose in it. The voyages of the navigators of the early sixteenth century must have seemed just as quixotic, though after any successful voyage the fruits of the expedition, in a commercial as well as a scientific and cultural way, could be readily appreciated. When we estimate the difference between the small sailing vessels of that time and the utter lack of facilities for the storage and {274} preservation of food as well as the dangers of the literally trackless ocean, some idea of the bravery of these hardy adventurers can be appreciated. Our steam vessels, with preserved foods and medicines usually available and the understanding of the dangers that they are to meet, has made our voyages comparatively simple, yet we have felt the inspiration of accomplishment. Columbus' Century is almost infinitely higher in the place that must be accorded to it for the spirit and the number of the men who ventured upon long voyages from which so many never returned and on which all trace was absolutely lost of many and many a vessel. In spite of the losses, there was never any dearth of men to take up the work of exploration and conquest, and their success revolutionized modern history. {275} CHAPTER VII AMERICA IN COLUMBUS' CENTURY
