CHAPTER XI

THORN MEETS THE CHILDREN OF THE SHELL MOUNDS

Every day Thorn worked for a little while at the chipping of stone axes, but he had plenty of time for play. One morning he ran to the river and jumped on his raft.

"Ha!" he said, "my other self jumped the stream with me. And now it leans over a shadow raft and reaches for a shadow pole."

He looked about him. On the grass lay the long shadows of the trees. In the clear water were the pictured banks.

"Everything has another self," he thought.

As he grew busy with his bow, he heard loud talking, and looked up and saw strange men and children coming along the other bank.
