Once, at the bottom of summer,
we pushed on — Caitlin and Jill and Peter
   and I—through the heat which lay
like a thick sheet of glass over everything,
   the trees only a smoke screen

   for the scorching air. Exhausted,
we wanted to go home, but Caitlin wanted
   to see the alligators—she was two,
she wouldn’t take no for an answer! We came out
   of the stifling tunnel of trees

   into the swamp, the sun
pressing everything flat as a photograph,
  no life anywhere, not even
a ripple ruffling the dark hair of the water.
  Then Peter’s dog barked

   and ran to the swamp grass,
a smudge of gray ash in the fire. Calling him,
   we turned to go. Suddenly, she came
out of nowhere, came straight toward us, hissing
   and flashing a mouthful of swords,

   the heavy board of her tail beating
the air. Maybe she had babies nearby, maybe she
  only protected her young, as anyone
would, but we didn’t wonder, we scooped up
  the dog and the baby and ran as fast
