rill

puro

noro A very small brook; a streamlet.
1797, w:Samuel Taylor Coleridge|Samuel Taylor Coleridge, w:Kubla Khan|Kubla Khan:

So twice five miles of fertile ground

With walls and towers were girdled round:

And there were gardens bright with sinuous rills,

Where blossomed many an incense-bearing tree;

And here were forests ancient as the hills,

Enfolding sunny spots of greenery.

And fainter, finer, trickle far

To where the listening uplands are;

To pause—then from his gurgling bill

Let the warbled sweetness rill,

And down the welkin, gushing free,

Hark the molten melody;
