These settlers were as quarrelsome as many of their predecessors and got on ill together. Governor White sailed for England for more immigrants and supplies, but when he reached that country he found the internal troubles so serious that he was kept away from America for three years. When finally he returned to Virginia, he was unable to find a member of the colony. On one of the trees was the word "CROATAN" cut in the bark, which seemed to indicate that the settlers had removed to a settlement of that name; but, though long and continuous search was made and many of the articles belonging to the settlers were recognized, not a person could be discovered. Sir Walter Raleigh sent several expeditions with orders to use every effort to clear up the mystery, but it was never solved. The story of the "Lost Colony" has led to a great deal of investigation and surmise. Two theories have supporters. The most probable is that all the settlers were massacred by Indians. Another is that they were adopted by the red men and intermarried among them. In support of this supposition is the fact that a long time afterward many members of the adjoining tribes showed unmistakable signs of mixed blood. There were so-called Indians with blonde hair, blue eyes, and light complexion--characteristics never seen among those belonging to the genuine American race. Holland's explorations in America were less important than those of any of her rivals. The thrifty Dutchmen were more anxious to secure trade than to find new countries, and seemed content to allow others to spend wealth and precious lives in penetrating to the interior of the New World and in planting settlements, which almost invariably succumbed to disaster. Early in the seventeenth century a company of English merchants sent out a skillful navigator named Henry Hudson to hunt for the elusive northwest passage. He took with him only eleven men, one of whom was his son. He made a brave effort to succeed, ploughing his way through the frozen regions until he passed the 80th degree of latitude, which was the furthest point then attained by man. But, within less than ten degrees of the pole, he was forced by the ice to turn back. THE DISCOVERY OF THE HUDSON RIVER.
