  • Counting alluvial plains
    The breathing inside of the range
    You touched me inside of my cage
    Beneath my shirt your hands embraced me
    Come to me feathered and frayed
    For I am the ugliest prey,
    For I am the ugliest prey
    The owl, the reckless reckless praise.

  • Should include explicit mention of meaning as "stratified" (picture layers of sediment). I find this usage more denotative than connotative these days.
