Read this excerpt from Kinnell's poem "Vapor Trail Reflected in the Frog Pond": And by paddies in Asia bones wearing a few shadows walk down a dirt road, smashed bl**ds ckers on their heel, knowing flesh thrown down in the sunshine dogs shall eat and flesh flung into the air shall be seized by birds, shoulder blades smooth, unmarked by old feather-holes, hands rivered by blue, erratic wanderings of the blood, eyes crinkled shut at almost seeing the drifting sun that gives us our lives.
