'in the half-light of dusk' Poem by Tom Clark

in the half-light of dusk
after the day has prepared
hard surfaces for inspection
before the night has plunged
things back into themselves
there is a settlement in which
the external and the internal are
continuous with the evening air
if you are alone at the edge
of shadows you are not alone
the hours of light shine in you
with a compacted energy that
also burns in tree and stone
partly revealed and partly veiled
