QUINCY, Mass.-- A previously unknown letter penned by the nation's sixth president, John Quincy Adams, has been found in a dusty box in the basement of Quincy City Hall.

The letter, dated Sept. 8, 1826, outlines the burial wishes of Adams' father, John Adams, the nation's second president.

The letter was recently discovered by a city attorney who was combing through some old city records.

John Quincy Adams wrote that his father, who had died two months earlier, and his mother, Abigail Adams, wished to be buried in the First Parish Church, and that a "plain and modest monument" be built in their memory.

John and Abigail Adams are buried in the basement of the church, as are John Quincy Adams and his wife, Louisa Catherine.

Quincy Mayor Thomas Koch plans to have the letter preserved and put on public display.
