During our evening conversations, Joseph would occasionally give us some of the most amusing recitals that could be imagined. He would describe the ancient inhabitants of this continent, their dress, mode of travelings, and the animals upon which they rode; their cities, their buildings, with every particular; their mode of warfare; and also their religious worship. This he would do with as much ease, seemingly, as if he had spent his whole life among them.
