If you think Paul Bunyan and Babe the Blue Ox are totally imaginary, you're in for a surprise: both are based in reality. Rogers traces their actualities to the upper reaches of Lower Michigan. He identifies one Fabian Joseph Fournier as the inspiration for Paul Bunyan. Although a crackerjack lumberman, Fournier was no all-American but a drunkard and brawler who supposedly had a double row of molars, the teeth marks of which he left on bars and foes. It was Fournier's 1875 death from a hammerblow on the head and the subsequent legal proceedings against the supposed perpetrator that gave rise to the Paul Bunyan myth, although H. L. Mencken eventually played a part in it, too. Babe, by the way, owes his currency to the fact that many lumbermen preferred oxen to horses for hauling trees out. Rogers has traced to ground some of the early Bunyan tales as well, enabling the reader to see how easily exaggeration came to the lumbermen. It's all very worthwhile for those seeking the roots of our country's greatest tree feller.
