The scene changes. Out into the world of stern adventure he passes, taking as naturally to the field and the frontier as the eagle to the air. At the age of twenty-one he is riding from Williamsburg to the French post at Venango, in Western Pennsylvania, on a mission for Governor Dinwiddie, which requires "courage to cope with savages and sagacity to negotiate with white men"--on that mission which Edward Everett recognizes as "the first movement of a military nature which resulted in the establishment of American Independence." At twenty-two he has fleshed his maiden sword, has heard the bullets whistle, and found "something charming in the sound;" and soon he is colonel of the Virginia regiment in the unfortunate affair at Fort Necessity, and is compelled to retreat after losing a sixth of his command. He quits the service on a point of military etiquette and honor, but at twenty-three he reappears as volunteer aide by the side of Braddock in the ill-starred expedition against Fort Duquesne, and is the only mounted officer unscathed in the disaster, escaping with four bullets through his garments, and after having two horses shot under him. The prophetic eye of Samuel Davies has now pointed him out as "that heroic youth, Colonel Washington, whom I can but hope Providence has hitherto preserved in so signal a manner for some important service to his country;" and soon the prophecy is fulfilled. The same year he is in command of the Virginia frontier forces. Arduous conflicts of varied fortunes are ere long ended, and on the 25th of November, 1759, he marches into the reduced fortress of Fort Duquesne--where Pittsburgh now stands, and the Titans of Industry wage the eternal war of Toil--marches in with the advanced guard of his troops, and plants the British flag over its smoking ruins. That self-same year Wolfe, another young and brilliant soldier of Britain, has scaled and triumphed on the Heights of Abraham--his flame of valor quenched as it lit the blaze of victory; Canada surrenders; the Seven Years' War is done; the French power in America is broken, and the vast region west of the Alleghenies, from the lakes to the Ohio, embracing its valley and tributary streams, is under the scepter of King George. America has been made whole to the English-speaking race, to become in time the greater Britain. Thus, building wiser than he knew, Washington had taken no small part in cherishing the seed of a nascent nation. [Illustration: WASHINGTON AT MOUNT VERNON] Mount Vernon welcomes back the soldier of twenty-seven, who has become a name. Domestic felicity spreads its charms around him with the "agreeable partner" whom he has taken to his bosom, and he dreams of "more happiness than he has experienced in the wide and bustling world."
