Two earlier readings are on July 9th, for Leland Kinsey, and July 23, Ellen Bryant Voight.
Here's a sample, Stone:
That would be my way.
Let somebody else become a dove
Or gnash with a tiger’s tooth.
I am happy to be a stone.
No one knows how to answer it.
Yet within, it must be cool and quiet
Even though a cow steps on it full weight,
Even though a child throws it in a river,
The stone sinks, slow, unperturbed
To the river bottom
