Classic Poem

If you prove right and I prove wrong,
A million years from now,
In language plain and frank and strong
My error I'll avow
To your dear waking face.

If I prove right, by God His grace,
Full sorry I shall be,
For in that solitude no trace
There'll be of you and me.

A million years, O patient stone,
You've waited for this message.
Deliver it a million hence;
(Survivor pays expressage.)
