"We went back that winter--One-Tusk and I; in time they all went," said Arrumpa. "It was too cold by the sea in winter. And the land changed. Even in Taku-Wakin's time it changed greatly. The earth shook and the water ran out of the marsh into the sea again, and there was hard ground most of the way to Two Rivers. Every year the tribes used to go down by it to gather sea food."

"It was so in our time," they said. "There were great heaps of shells by the sea where we came and dried fish and feasted."
"Shell Mounds," said Oliver. "I've heard of those, too. But I never thought they had stories about them."
"There is a story about everything," said the Buffalo Chief; and by this time the children were quite ready to believe him.
