Trees used as fence posts for pastures, barb wire and electrified wires.  absorbed by their hosts, later cut when the land was converted to other uses.  not a moral narrative about the resilience of nature, yet the ability to incorporate, and in such a way that the invader can’t be removed from the host, seems extraordinary, as would be a cyborg, or foreign materials ingested and absorbed by the organs. I think of the lumps of pencil lead in other kids hands, dark spots, absorbed, painless and grotesque. I remember the mental health museum in st. joe missouri and all the sharp metal objects extracted from the guts of obsessed swallowers. why not leave them be, to allow the host to wrap it around their living material. the willingness of organic material to adapt to modification.
