Always the Swedes gave the Minquas generous measures of shell strings in exchange for beaver. Whether it was common white roanoke made from the cockle shells found in quantity along some local beaches, valuable peake strung with purple conch shell, or a variety of the even more highly prized Long Island wampum, measurements were uniformly generous. And since fathoms, ells and yards were roughly estimated by using the length of one’s arm, the giant Susquehannocks did very well for themselves. Resourceful as usual, the Dutch began manufacturing false wampum to meet the competition. But the savages were quick to detect the counterfeit and wouldn’t accept it. * * * * * Meanwhile, some English traders from the New Haven Colony, which was being hemmed in and cut off from the Indian trade of New England, had come down to test out the prospects on the Delaware River and were very much impressed. George Lamberton, Nathaniel Turner and others decided to form a company to purchase land about the Schuylkill River as well as the unoccupied country stretching northward from Cape May. As usual the natives obliged them, regardless of prior deeds, and the New Englanders soon had a colony at Varkens Kill, now Salem Creek in New Jersey. Everything might have been all right if the Englishmen had remained on the land they bought on the east side of the river. But this was not destined to be. Although there were some twenty families who cleared land and planted crops in 1641 at Varkens Kill, these people were primarily fur traders. They discovered that the east side of the river was too far from the trading grounds of the Indians. The next year they established a fort, building dwellings and a truck house, on the west side of the river at the mouth of the Schuylkill. This trading post, located on Province Island in present Philadelphia, was on land claimed by both the Swedes and the Dutch. Actually it must have incorporated whatever was left of the abandoned Dutch installation built there originally by Arendt Corssen in 1633. In any case the men from New Haven, after starting a lively Indian trade, made it clear that they would countenance no competition within their newly acquired precincts. The Swedes and the Dutch, who had been operating under a kind of armed truce in this area, united promptly in the face of this threat to their common interest. Two armed sloops were sent out by the Council of New Netherland, and Jan Jansen with the cooperation of the Swedes attacked and burned out the interlopers. George Lamberton managed to escape in his pinnace with a few of his people. But most of the New Englanders were captured and shipped off to Manhattan as prisoners.
