Six brown cows walk down to drink
    (All the little fishes blew bubbles at the may-fly).
Splash goes the first as he comes to the brink,
   Swish goes the tails of the five who follow…
Twelve brown cows bend drinking there
   (All the little fishes went waggle-tail, waggle-tail) —
Six from the water and six from the air;
   Up and down the river darts a blue-black
       swallow.
