"Poetry," 1925 draft:

I too, dislike it:
there are things that are important beyond all this fiddle.
The bat, upside down; the elephant pushing,
a tireless wolf under a tree,
the base-ball fan, the statistician—
"business documents and schoolbooks"—
these phenomena are pleasing,
but when they have been fashioned
into that which is unknowable,
we are not entertained.
It may be said of all of us
that we do not admire what we cannot understand;
enigmas are not poetry.

"Poetry," 1932 (just the ending)

*****business documents, school-books,

trade reports—these phenomena
are important; but dragged into conscious oddity by
**half poets, the result is not poetry.
*****This we know. In a liking for the raw material in all it rawness,
*********and for that which is genuine, there is liking for poetry.
