Read this excerpt from kinnell's poem "vapor trail reflected in the frog
pond":
and i hear,
coming over the hills, america singing,
her varied carols i hear:
crack of deputies' rifles practicing their aim on stray dogs
at night,
sput of cattleprod,
tv going on about the smells of the human body,
curses of the soldier as he poisons, burns, grinds, and
stabs
the rice of the world,
with open mouth, crying strong, hysterical curses.
what is this part of the poem about?
