One spring day, the loggers on the Wisconsin River discovered a huge log jam, the biggest they'd ever seen. The logs were piled about two hundred feet high and the jam went upriver for a mile or more. Those loggers chopped and hauled at the jam, but it wouldn't budge an inch. So they called for Paul Bunyan to give them a hand.
Paul Bunyan and Babe the Blue Ox sized up the log jam. Then Paul told the loggers to stand back. He put Babe in the river in front of the log jam and began shooting his rifle, peppering the Blue Ox with shot. Babe thought he was being bothered by a particularly nasty breed of fly, so he began swishing his tail back and forth.
Well, that stirred things up a bit in the river. It got so agitated that the water began to flow upstream, taking the logs with it. Bit by bit, the log jam broke apart. Finally, Paul pulled Babe out of the water, and the river and logs began to float downstream again the way they should.
