Read "February" at The Eldritch Dark:
While this is not a particularly notable poem by Clark Ashton Smith (CAS), the third stanza is quite potent with visual imagery:
Fragile as dreams, afloat
Between the earth and skies,
Beyond serene, remote,
Blue-folded hills the fair and moon-white mountains rise.
It's worth noting that the version of this poem at The Eldritch Dark renders the work with five-line stanzas. In contrast, the version of the same poem in the Hippocampus Press edition of The Complete Poetry and Translations of Clark Ashton Smith presents each stanza as a quatrain, with long last lines. Given the careful editorial work of S.T. Joshi and David E. Schultz, I suspect the latter is correct, and I've used that formatting above.
