The Character and Influence of the Indian Trade in Wisconsin is a book by Frederick Jackson Turner. Turner was an American historian and author here delving into the Indian trade between early European settlers and the indigenous of America. Excerpt: "The chroniclers of the earliest voyages to the Atlantic coast abound in references to this traffic. First of Europeans to purchase native furs in America appear to have been the Norsemen who settled Vinland. In the saga of Eric the Red we find this interesting account: "Thereupon Karlsefni and his people displayed their shields, and when they came together they began to barter with each other. Especially did the strangers wish to buy red cloth, for which they offered in exchange peltries and quite grey skins. They also desired to buy swords and spears, but Karlsefni and Snorri forbade this. In exchange for perfect unsullied skins the Skrellings would take red stuff a span in length, which they would bind around their heads. So their trade went on for a time, until Karlsefni and his people began to grow short of cloth, when they divided it into such narrow pieces that it was not more than a finger's breadth wide, but the Skrellings still continued to give just as much for this as before, or more."
