Under the Waterfall (I)

"Whenever I plunge my arm, like this,
In a basin of water, I never miss
The sweet sharp sense of a fugitive day
Fetched back from its thickening shroud of gray.
Hence the only prime
And real love-rhyme
That I know by heart,
And that leaves no smart,
Is the purl of a little valley fall
About three spans wide and two spans tall
Over a table of solid rock,
And into a scoop of the self-same block;
The purl of a runlet that never ceases
In stir of kingdoms, in wars, in peaces;
With a hollow boiling voice it speaks
And has spoken since hills were turfless peaks."

"And why gives this the only prime
Idea to you of a real love-rhyme?
And why does plunging your arm in a bowl
Full of spring water, bring throbs to your soul?"
