But it's a long, long while From May to December; And the days grow short When you reach September.

-Anderson, Maxwell
  'September Song' (music by Kurt  Weill).

Through breaks of the cedar and sycamore bowers Struggles the light that is love to the flowers; And, softer than slumber and sweeter than singing, The notes of the bell-birds are running and ringing. The silver-voiced bell-birds, the darlings of daytime! They sing in September their songs of the May-time.

-Kendall, Henry Clarence
  Leaves from  Australian Forests,'Bell-Birds'.

Up from the meadows rich with corn, Clear in the cool September morn.

-Whittier,John Greenleaf
  'Barbara Frietchie', opening lines.
