After the ghosts had been identified, photographed, and recorded with measured drawings, the information was used to help reconstruct the cellar stair.  The boards proved to be vitally important because they not only supplied the exact size of the risers, treads, nosing and the angle of the stair, but they also gave the Restoration Team the size and finish of the stair’s enclosure.  When this information was combined with the evidence of the stair's framing found on the walls of the North Cellar Passage, the architects were able to produce a design for a reconstructed stair that was amazingly close to the original, even including its ca. 1812 paint color.
