An intimacy with a family like this, in which the frankness and simplicity of rural and colonial life were united with European refinement, could not but have a beneficial effect in moulding the character and manners of a somewhat homebred schoolboy. It was probably his intercourse with them, and his ambition to acquit himself well in their society, that set him upon compiling a code of morals and manners which still exists in a manuscript in his own handwriting, entitled "rules for behavior in company and conversation." It is extremely minute and circumstantial. Some of the rules for personal deportment extend to such trivial matters, and are so quaint and formal, as almost to provoke a smile; but in the main, a better manual of conduct could not be put into the hands of a youth. The whole code evinces that rigid propriety and self control to which he subjected himself, and by which he brought all the impulses of a somewhat ardent temper under conscientious government. Other influences were brought to bear on George during his visit at Mount Vernon. His brother Lawrence still retained some of his military inclinations, fostered no doubt by his post of Adjutant General. William Fairfax, as we have shown, had been a soldier, and in many trying scenes. Some of Lawrence's comrades of the provincial regiment, who had served with him in the West Indies, were occasional visitors at Mount Vernon; or a ship of war, possibly one of Vernon's old fleet, would anchor in the Potomac, and its officers be welcome guests at the tables of Lawrence and his father-in-law. Thus military scenes on sea and shore would become the topics of conversation. The capture of Porto Bello; the bombardment of Carthagena; old stories of cruisings in the East and West Indies, and campaigns against the pirates. We can picture to ourselves George, a grave and earnest boy, with an expanding intellect, and a deep-seated passion for enterprise, listening to such conversations with a kindling spirit and a growing desire for military life. In this way most probably was produced that desire to enter the navy which he evinced when about fourteen years of age. The opportunity for gratifying it appeared at hand. Ships of war frequented the colonies, and at times, as we have hinted, were anchored in the Potomac. The inclination was encouraged by Lawrence Washington and Mr. Fairfax. Lawrence retained pleasant recollections of his cruisings in the fleet of Admiral Vernon, and considered the naval service a popular path to fame and fortune. George was at a suitable age to enter the navy. The great difficulty was to procure the assent of his mother. She was brought, however, to acquiesce; a midshipman's warrant was obtained, and it is even said that the luggage of the youth was actually on board of a man of war, anchored in the river just below Mount Vernon.
