The Pearl S. Buck bedroom floor has had several floor planks removed to assess structural integrity. The exposed beams reveal workmanship of wooden pegs; not a single nail. The Pennsylvania Dutch barn and house builders of the area have left exceptional work evident in this 1825 portion of the house. Roman numerals superficially carved into the end of each beam reflect mortise and tenon joinery.
The Roman numerals are in ascending order across the floor. This indicates that the beams were cut and hewn off site and joined together here in the house.

Removal of floorboards revealed planks held together solely by wooden pegs. The roman numerals etched into the wood are visible above.
