Wayne describes Chris as short, lean, and wiry. He hypothesizes that Chris may have had a trace of Greek or Chippewa blood in his heritage. Wayne also relates that Chris was near-sighted and that he was gifted with sensitive good looks.
According to Wayne, Chris was also a hard worker who could be trusted to perform the dirtiest jobs at the grain elevator. Chris worked with diligence at every task he was given, and he was respected by the other laborers for his thoroughness and integrity. Wayne relates that his young friend fit in well in Carthage; Chris was the kind of young man who appreciated Carthage's small town coziness, its modest respectability, and its working-class ethics.
In the book, Wayne also describes Chris as an obstinate young man who lived by a set of extremely rigid principles. Wayne deduces (rightly) that it was probably Chris's uncompromising personality that caused an irreparable rift to develop between him and his father, Walt.
Wayne relates that Chris was also a very idealistic young man: he prized chastity and moral purity in the same way Tolstoy and Thoreau did. As a result, Chris did not take relationships with women lightly. Wayne reports that Chris might well have been celibate during the entire time he knew him. Chris's idealism led him to be obsessed with the wilderness. In the spirit of John Muir and Thoreau, Chris sought communion and union with nature. He sought the wild in the same way that some men sought women.
In all, Wayne describes Chris as a peerless young man who charmed everyone he interacted with in Carthage.
