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 go 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.
