Wallace Stevens and the Pond at the End of Time

In The State of the Art by David Lehman, Lehman writes that when President Clinton was president, he hosted a "Millennium Evening" to celebrate American poetry.  The event was beamed to 220 sites and was  cybercast, and a transcript was made available to the public.  Lehman commented: "it was no less pleasurable for the accidental transformations that hasty typing produced--as when Wallace Stevens's 'the palm at the end of the mind' turned into 'the pond at the end of time.'"
