Once Wisagatcak killed a bear; then he skinned it, and cut it in pieces, and cooked all of them. While he was cooking, he looked up and saw Muskrat in the river. Now the bear’s grease would not harden, so Wisagatcak told Muskrat to swim through the water with it. Muskrat did so, and when he returned Wisagatcak made his tail much thinner and smaller. Muskrat formerly had a broad, fleshy tail like Beaver’s, and it was a great annoyance to him.

“Now see how fast you can go,” said Wisagatcak. Muskrat jumped into the river and swam so rapidly that he broke the grease bladder which he still carried. All the grease and oil came out. That is why Muskrat leaves such a smooth, oily wake when he swims.
