It went like this:
Trotter: Now, uh, Ms. Dickinson, being an expert on your own poetry…how many poems did you write that used the word “February.”
Emily Dickinson: It’s a trick question.
Trotter: Does that mean you can’t answer it?
Emily Dickinson: No, it’s a trick question!
Well, it is indeed a bit of a trick question. “February” does show up in three poems (“White as an Indian Pipe,” “Although I put away his life,” and “No Brigadier throughout the Year”); however, Dickinson always spelled the month as “Febuary,” not “February” (and various volumes of her poetry have retained her spelling of “Febuary”).
Sooo…on one hand, “zero” poems include “February” – but they do use the word “Febuary.” On the other hand, one could say that “three” poems include “February” ( it’s just that the name of the month is misspelled). Also, “A February Day,” line 6 in “No Brigadier throughout the Year” is actually “A January Day” in one variation of the poem sent to Dickinson’s sister-in-law Susan – so maybe the answer is “two” poems?
