After Dark Vapours Have Oppressed Our Plains

After dark vapours have oppressed our plains
For a long dreary season, comes a day
Born of the gentle South, and clears away
From the sick heavens all unseemly stains.
The anxious month, relieving from its pains,
Takes as a long-lost right the feel of May,
The eyelids with the passing coolness play,
Like rose leaves with the drip of summer rains.
And calmest thoughts come round us
