Thanksgiving Day lyrics

One day is there of the series
   Termed Thanksgiving day,
Celebrated part at table,
   Part in memory.

Neither patriarch nor pus*y,
   I dissect the play;
Seems it, to my hooded thinking,
   Reflex holiday.

Had there been no sharp subtraction
   From the early sum,
Not an acre or a caption
   Where was once a room,

Not a mention, whose small pebble
   Wrinkled any bay, —
Unto such, were such assembly,
   'T were Thanksgiving day.
