About this time, a company was formed, called the Ohio Company, for the purpose of opening a trade route through northern Virginia and Maryland. George Washington's two elder brothers, Lawrence and Augustine, were interested in the 'enterprise'; and they naturally called in their young surveyor brother to consultation. The project sounded fascinating, but presented many elements of danger. The French were becoming more and more active, and making warlike preparations to seize and hold all the western frontier. In order to develop and hold this land against the French and their Indian allies, it was necessary to place the work in the hands of a military leader. George Washington was at this time only nineteen years old, but fully grown--a man of powerful physique, hardened and seasoned by his outdoor life. Despite his youth and lack of military experience, the Ohio Company secured for him the appointment of adjutant general of this district. Washington at once placed himself under several military officers of his acquaintance, among them a Major Muse, and soon acquired at least the rudiments of warfare, the manual of arms. The broader school of tactics he was to acquire for himself in the field of experience. An interruption to his military career came in the illness of his brother Lawrence. A voyage to the West Indies was determined upon, for the invalid, and George accompanied him--on the young man's first sea voyage, and of which he has left us entertaining glimpses in his ever-faithful diary. But after a winter in the South Seas, Lawrence grew worse and was brought home to die. George, though only twenty, was made one of the executors to the estate, Mount Vernon, which became henceforth his home. Shortly afterward, we find George Washington given still higher office, but one which entailed heavy responsibilities. The newly appointed governor of the state, Robert Dinwiddie, growing uneasy at the constant reports of alliances between the French and Indians, determined to send a commissioner to the French commander, to ask by what right he was building forts in English dominions; and also to treat with the Indians, in the way of counter proposals against the French. It was a hazardous mission, and one which also involved tact, diplomacy, and a first-hand knowledge of the wilderness. But we are not much surprised to find Washington, at twenty-one, given the commission of major and sent on this undertaking.
