"If this trade should be free to all without restriction, the fur-bearing animals would be too much hunted and the furs would be sold here below their value." Kiliaen van Rensselaer, November 25, 1633.
The St. Pieter, sailing out of Amsterdam in 1611, was the first ship whose mission was to engage in the fur trade, engendered by the fashion in Europe to wear hats made of felted beaver fur. It was followed by other vessels whose cargoes of trade goods would forever change Indian lives and foster, to one degree or another, often fitfully, a mutual dependency. The furs Natives trapped and then packed overland to Fort Orange were exchanged for iron axes, knives, copper and brass kettles, scissors, pins, awls, and glass beads. These and other goods were then substituted by the Indians for what they had long manufactured for themselves, such as clay cooking pots, basketry, and stone, bone, and wood tools. In pursuit of their own economic interests, the Dutch viewed the Native people of the region differently: those in the Hudson Valley, given their proximity to the Dutch and their settlements, were seen as more a potential threat rather than valuable consumers, while the Mohawks held the key to the interior and its wealth of furs.
With the rapid depletion of beaver in the valley below Fort Orange, Indians there took to selling off their lands for needed trade goods. From places to the west, through Mohawk country, the flow of furs to Fort Orange remained fairly constant--thousands of pelts were shipped downriver to New Amsterdam and from there to the United Provinces. Wampum or sewant, produced by Indians in southern New England and Long Island, soon became the medium of exchange for this trade.
