The time in which they grew up was calculated to mould characters of strength. Self-control and self-denial had been needed in the protracted wars with France. Self-reliance had been learnt in the hard school of adversity. Imagination was quickened by the heroism of the struggle which had ended in the final victory of our arms. And to the generations born in the early days of the nineteenth century lay open fields wider than were offered to human activity in any other age of the world's history. Now at last the full fruits of sixteenth-century discovery were to be reaped. It was possible for Gordon, by the personal ascendancy which he owed to his single-minded faith, to create legends and to work miracles in Asia and in Africa; for Richard Burton to gain an intimate knowledge of Islam in its holiest shrines; for Livingstone, Hannington, and other martyrs to the Faith to breathe their last in the tropics; for Franklin, dying, as Scott died nearly seventy years later, in the cause of Science, to hallow the polar regions for the Anglo-Saxon race. Darkest Africa was to remain impenetrable yet awhile. Only towards the end of the century, when Stanley's work was finished, could Rhodes and Kitchener conspire to clasp hands across its deserts and its swamps: but on the other side of the globe a new island-empire had been already created by the energy of Wakefield, and developed by the wisdom of Parkes and Grey. In distant lands, on stricken fields less famous but no less perilous, Wellington's men were applying the lessons which they had learnt in the Peninsula. On distant seas Nelson's ships were carrying explorers equipped for the more peaceful task of scientific observation. In this century the highest mountains, the deepest seas, the widest stretches of desert were to reveal their secrets to the adventurers who held the whole world for their playground or field of conquest.
