From Preface: -Peace hath her victoriesNo less renown'd than war.- The love of adventure, the expectation of the unexpected, have ever prompted men stout of heart, and ready of resource, to brave the perils of wilderness and sea that they might set their feet where man never trod before. The world owes much to the explorers who have faced hostile savages, stood in jeopardy from the cobra and the lion, the foes as deadly which lurk in the brook which quenches thirst. A traveller like Clarke takes his life in his hands. He breaks a path which leads he knows not whither: it may bring him to a shore whence he has no ship to sail from; it may end in an abyss he cannot bridge. The thickets rend and sting him, poison may colour a tempting grain or berry, frost may deaden his energies and lull him to the sleep that knows no waking. He has but little aid from science: beyond food and medicine he carries little more than a watch, a compass, a rifle, and a cartridge belt. Beyond all instruments and weapons are his skill, agility, gumption, diplomacy. And these resources in no mean measure are shared by the man for whom he prepares the way, the immigrant, who, in the early days of settlement, requires a constancy even higher than the explorer's own. It is one thing to traverse a wilderness under the excitement of hourly adventure; it is another thing to stay there for a lifetime and convert it to a home. The race of American explorers is not extinct. Major Powell is with us to-day, hale and hearty still. Peary, in the prime of his powers, is as capital an example of courage and resource as ever threw themselves upon the riddle of the frozen north. Beyond the Arctic and Antarctic circles little remains unknown on earth. When at last every rood of ground and knot of sea is mapped and charted, whither shall the explorer direct his steps? He cannot repeat the conquests of Lewis and Clarke, Pike and Peary, but he need not on that account fold his hands so long as a brave heart and a quick wit are wanted in the world."
