In Clark's day a boy proficient in mathematics did not have to look far for a profession which was considered both honorable and lucrative, and that was the surveyor's profession. It was doubly enticing to a youth of brains and daring; the call for surveyors to go out into the rich empire beyond the Alleghanies was loud and continuous, and had been since Lord Fairfax sent that young Virginia surveyor into the singing forests of the Upper Potomac before the outbreak of the Old French War; and from George Washington down, you may count many boys who went into the West as surveyors and became the first men of the land. The surveyor had many, if not all, the experiences of the soldier; and every boy in Virginia envied the soldier of the French War. The surveyor found the good lands, and here and there surveyed a tract for himself; this, in time, would become of great value. The surveyor knew the Indians and their trails; he knew where the best hunting-grounds and salt-licks were located; he knew where the swamps lay, and the fever-fogs that clung to them; he knew the rivers, their best fishing-pools, and how far up and down they were navigable; he was acquainted with everything a man would wish to know, and he knew of things which every man wished to escape,--floods, famines, skulking redskins, fevers. For these reasons the surveyors became the men needed by generals to guide the armies, by the great land-companies to point out right fields for speculation, by transportation companies and quartermasters and traders to designate the best paths to follow through the black forests. The tried, experienced surveyor was in an admirable position to secure a comfortable fortune for his labor. While Washington (the largest landholder in America in Clark's day--and half his lands in the West) selected in person much of his own land, yet, as we have seen, the time came when he employed William Crawford to find new lands for him. Perhaps young Clark came but slowly to a realization that he could enter the fine profession of a surveyor; but when the time came to decide he seized upon the opportunity and the opening with utmost enthusiasm and energy. Both of his grandfathers had been surveyors to a greater or less extent; possibly their old instruments were in his father's possession. If so, these were taken out and dusted, and the boy was set to work surveying, probably, his father's farm. Its dimensions were well known, and the boy could be sure of the accuracy or inaccuracy of his experiments. In time George probably was called upon to do odd pieces of surveying in the neighborhood in which he lived; thus the days and the years went by, each one fitting the lad for his splendid part on the world's stage of action. The first act in the drama was Clark's introduction to the West--the land of which he had so often dreamed, and which he now in his twentieth year went to see.
