In the meantime, three Frenchmen, Father Hennepin, Michel Accaut, and one Du Gay, in obedience to La Salle's orders, had ventured to the upper waters of the Mississippi, and were made prisoners by a wandering tribe of Sioux. Not far from the falls of St. Anthony Father Hennepin met with the famous forest ranger, Duluth, who was better acquainted with the Sioux country than any other living Frenchman, and was forming ambitious designs to explore the whole western region beyond Lake Superior. Father Hennepin, who had been adopted by an aged Sioux chief, was free to follow Duluth back to the French post at the Straits of Mackinac. This adventure of Father Hennepin is famous in history, not on account of any discoveries he actually made, but on account of the claim he attempted to establish some years after his journey, of having followed the Mississippi to the Gulf. In the first edition of his book, printed in 1683--_Description de la Louisiane_--no such claim was ever suggested, and it was only in 1697 that the same work appeared in an enlarged form,--_La Nouvelle Decouverte_--crediting Hennepin with having descended the great river to its outlet. It is not necessary here to puncture a falsehood which was long ago exposed by historical writers. His history of having reached the Gulf of Mexico is as visionary as the traveller's tales of Norumbega. Indeed, he could not even claim a gift of fertile invention in this case, as the very account of his alleged discovery was obviously plagiarised from Father Membre's narrative of La Salle's voyage of 1682, which appears in Le Clercq's _Premier Etablissement de la Foy_. {188} When La Salle was again able to venture into the west he found the villages of the Illinois only blackened heaps of ruins--sure evidence of the Iroquois having been on the warpath. During the winter of 1681 he remained at a post he had built on the banks of the St. Joseph in the Miami country, and heard no news of his faithful Tonty. It was not until the spring, whilst on his way to Canada for men and supplies, that he discovered his friend at Mackinac, after having passed through some critical experiences among the Iroquois, who, in conjunction with the Miamis, had destroyed the villages of the Illinois, and killed a number of those Indians with their customary ferocity. Tonty had finally found rest and security in a village of the Pottawattomies at the head of Green Bay.
