BackClue 4: Wampum shell beads
Special beads, called wampum shell beads, were found at what is believed to be Hole-in-the-Day's cabin. They were made in Albany, N.Y., from New England clam shells and were used by American Indians as money. Doug Birk was touring the Smithsonian Institution, a museum in Washington, D.C., when he saw the same kind of beads on display. The information card said that they had belonged to Chief Hole-in-the-Day from Minnesota. Unfortunately, the Smithsonian lost its old notes on where it got its beads.
