Late in the day the fog
wrung itself out like a sponge
in glades of rain,
sieving the half-invisible
cove with speartips;
then, in a lifting
of wisps and scarves, of smoke-rings
from about the islands, disclosing
what had been wavering
fishnet plissé as a smoothness
of peau-de-soie or just-ironed
percale, with a tatting 
of foam out where the rocks are,
the sheened no-color of it,
the bandings of platinum
and magnesium suffusing,
minute by minute, with clandestine
rose and violet, with opaline
nuance of milkweed, a texture
not to be spoken of above a whisper,
began, all along the horizon,
gradually to unseal
like the lip of a cave
or of a cavernous,
single, pearl-
engendering seashell.
