Extract from the Diary of John Quincy Adams: George Hay on Thomas Jefferson

23. VII. ... Mr Hay spoke as he always does with extreme bitterness of Mr Jefferson, whom he declares to be one of the most insincere men in the world ... Mr Jefferson – His enmity to Mr Monroe was inveterate though disquised, and he was at the bottom of all the opposition to Mr Monroe in Virginia.
