One Day is there of the Series

One Day is there of the Series
Termed Thanksgiving Day.
Celebrated part at Table
Part in Memory.

Neither Patriarch nor Pussy
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 Sea,
Unto Such, were such Assembly
'Twere Thanksgiving Day.
