If nothing else (the matter may be sloppy,—
But that's no matter if there's ample copy)
So that the Author's face could be unmasked
And recognized without a question asked;
Or, so identify Calliope
By strident notes of high-toned quality;
Or thus detect some Poet's "fist" and style
By I. O. U.'s unhonored yet awhile.
The Pirates thus would cease perforce their trade,
And Bacon would not be confused with Ade.
