Even the gentlest natures are powerful to influence the character of others for good. Thus Wordsworth seems to have been especially impressed by the character of his sister Dorothy, who exercised upon his mind and heart a lasting influence. He describes her as the blessing of his boyhood as well as of his manhood. Though two years younger than himself, her tenderness and sweetness contributed greatly to mould his nature, and open his mind to the influences of poetry: "She gave me eyes, she gave me ears, And humble cares, and delicate fears; A heart, the fountain of sweet tears, And love and thought and joy." Thus the gentlest natures are enabled, by the power of affection and intelligence, to mould the characters of men destined to influence and elevate their race through all time. Sir William Napier attributed the early direction of his character, first to the impress made upon it by his mother, when a boy; and afterwards to the noble example of his commander, Sir John Moore, when a man. Moore early detected the qualities of the young officer; and he was one of those to whom the General addressed the encouragement, "Well done, my majors!" at Corunna. Writing home to his mother, and describing the little court by which Moore was surrounded, he wrote, "Where shall we find such a king?" It was to his personal affection for his chief that the world is mainly indebted to Sir William Napier for his great book, 'The History of the Peninsular War.' But he was stimulated to write the book by the advice of another friend, the late Lord Langdale, while one day walking with him across the fields on which Belgravia is now built. "It was Lord Langdale," he says, "who first kindled the fire within me." And of Sir William Napier himself, his biographer truly says, that "no thinking person could ever come in contact with him without being strongly impressed with the genius of the man." The career of the late Dr. Marshall Hall was a lifelong illustration of the influence of character in forming character. Many eminent men still living trace their success in life to his suggestions and assistance, without which several valuable lines of study and investigation might not have been entered on, at least at so early a period. He would say to young men about him, "Take up a subject and pursue it well, and you cannot fail to succeed." And often he would throw out a new idea to a young friend, saying, "I make you a present of it; there is fortune in it, if you pursue it with energy." Energy of character has always a power to evoke energy in others. It acts through sympathy, one of the most influential of human agencies. The zealous energetic man unconsciously carries others along with him. His example is contagious, and compels imitation. He exercises a sort of electric power, which sends a thrill through every fibre--flows into the nature of those about him, and makes them give out sparks of fire.
