and its dangers, mere incidents along the way. Not so for the true explorer. Impelled by an inborn curiosity, an intense craving to see new lands, new peoples, and driven by an incurable restlessness of spirit, he penetrates to the remotest corners of the earth, braving every danger, surmounting every difficulty, and asks but little of the world in the way of tangible returns. For him the life of the trail, the triumph over obstacles, the thrill of danger, are things in themselves desirable and beyond price; his reward lies not in the attainment, but in the quest. There may be few indeed for whom no other motives enter, but it is nevertheless true that for most great travelers, however much they may deceive themselves into thinking that they follow other and, as they believe, higher calls, it is the master motive.
THE MOTIVE OF CONQUEST
A different force, but one which has at all times been effective, is that of war or conquest. To the explorer enrichment of experience, not increase of possessions, is the aim; he does not care to whom the world belongs if only he may be free to travel therein. The conqueror, however, demands possession, and the lust for it and for revenge has, in the case of savage and civilized alike, led men into distant lands and among strange people. From the Iroquois who, sometimes alone, sometimes in company with a handful of others, went from the Hudson a thousand miles westward to the Mississippi to strike a blow at the hated Sioux, to Attila and the other leaders of those hordes which poured their thousands into mediæval Europe from the farthest East; from Alexander and his conquest of most of the old world to Cortez and Pizarro and their conquest of much of the new, in varying degree and at different times war has made of the conqueror a traveler. To such as these it is not the beauty but the wealth of a country that makes it desirable, and interest in its people lies more in their exploitation than in any other field.
THE MOTIVE OF RELIGION
Another very potent incentive to travel has been religion. From its influence have developed the pilgrim and the missionary, types
