Read "The End of Autumn" at The Eldritch Dark:
This lyric poem from Clark Ashton Smith (CAS) is filled with some wonderful imagery, and the onset of the coming season is captured with an icy touch in the closing stanza:
Bleak with the winter's breath,
A wind comes down; fantastic skeletons
Of steel and bronze,
Creak the cold willows in a dance of death.
"The End of Autumn" really captures the specific experience of being out at dusk when the first intimations of winter are in the air, and you can feel the arrival of short days and cold nights.
