As each settlement became more thickly settled the more venturesome spirits pressed on into the mountains. And as they moved forward, clearing forests and planting ground for their bread, they dislodged hunters and trappers who had preceded them. For all of them there was always the troublesome Indian to be reckoned with. A cunning warrior, he pounced upon the newcomer at most unexpected times. To maintain a measure of safety the pioneer began to build block houses and forts along the watercourses traveled by the Indians. Fur-trading posts were set up by the Crown but even when the Indian seemed satisfied with the exchange he might take prisoner a trader or explorer and subject him to torture, or even put him to death. The homes of settlers were objects of constant attack. It would take white men of more cunning than the Indian to deal with him: fearless and daring fighters. About the time Dr. Walker had started on his expedition in 1755, a family living in Pennsylvania packed up their belongings and moved down into the Valley of Virginia. There were the father, his sons, and his brothers. They hadn't stayed long in Rockingham County, barely long enough to raise a crop, when they moved again. This time they journeyed on down to the valley of the Yadkin River in North Carolina and there they stayed. All but one son--Daniel Boone, a lad of eighteen. Even as a boy he had roamed the woods alone, and once was lost for days. When his father and friends found him, guided by a stream of smoke rising in the distance, Daniel wasn't in tears. Instead, seated on the pelt of a wild animal he had killed and roasting a piece of its meat at the fire, he was whistling gaily. He had made for himself a crude shelter of branches and pelts. It was useless to chide his son, the older Boone found out. So he saved his breath and let Daniel roam at his will. Soon the boy was exploring and hunting farther and farther into the mountains. On one such venture the young hunter alone "cilled a bar" and left the record of his feat carved with his hunting knife upon a tree. His imagination was fired with the tales of warfare about him, of the courage and independence of the men who dwelt far up in the mountains. He knew of the heroism of George Washington who, four years after the Boones left Pennsylvania, had led a company of mountain men against the French. He had heard the stories of how Washington had been driven back with his mountain men at Great Meadows. Boone longed to be in the thick of the fray. So in 1755, when General Braddock came to "punish the French for their insolence" and Washington accompanied him with one hundred mountain men from North Carolina, Daniel Boone, for all his youth, was among them--as brave a fighter and as skilled a shot as the best.
