"President Lincoln gave a copy of the Gettysburg Address to each of his two private secretaries, John Nicolay and John Hay. According to Nicolay, Lincoln had written the first part of the speech on Executive Mansion stationery, and the second page in pencil on lined paper right before the dedication on November 19, 1863. Matching folds are still evident on the two pages of the Nicolay draft, supporting the eyewitness' argument that Lincoln kept it in his coat pocket before the ceremony."

"New York City Hall sits majestically inside a nostalgic, well-manicured park, topped with a beautiful old fountain straight out of gaslight-era New York. But its serenity belies the frantic pace of government inside City Hall walls, and disguises a tumultuous, vibrant history. There have actually been two other city halls -- one an actual tavern, the other a temporary seat of national government -- and the one we're familiar with today is a little less than 200 years old. Join us as we explore the unusual history of this building, through ill-executed fireworks, disgruntled architects, and its near-destruction -- to be saved only by a man named Grosvenor Atterbury. PLUS: We look at the park area itself, a common land that once catered to livestock, British soldiers, almshouses and a big, garish post office."
