“Let the trumpet of the day of judgment sound when it will, I shall appear with this book in my hand before the Sovereign Judge, and cry with a loud voice, This is my work, there were my thoughts, and thus was I.

—Administration in the State of Texa, U.S. public relief program (1935-1943)
“A pity beyond all telling
Is hid in the heart of love.”
