Quiet, of course, it adheres to
The cracks of water pipes, velvets
Velours them; an enriching
Unnatural ruff swathing the urban "manifestation":

It musts, it is alone.“Moss”, by Jon Silkin
as quoted in The Unofficial Countryside, by Richard Mabey (introduction by Iain Sinclair)
The next step (of course) is to request Nature With Man from the university library.
