Thurston devotes a lot of thought to his coffin-making practice, to the extent that he can’t comprehend Levi’s lack of understanding. His single-minded devotion to his work and resultant inability to sympathize with others reinforces his isolated, antisocial nature. The types of coffins he lists, including the one that would grow a tree to house a cormorant, all have slightly magical features, contributing to the novel’s streak of magical realism and suggesting that the power of nature grows when death and grief are involved.
