Letter to King David's Lodge No. 1 Newport Rhode Island, Aug. 22, 1970
  This is one of George Washington's Masonic sentiments, carved into the marble at the Memorial Museum:  

"Being persuaded that a just application of the principles on which the Masonic fraternity is founded must be promotive of private virtue and public prosperity, I shall always be happy to advance the interests of the society, and to be considered by them as a deserving brother."
