    This is a good example of the mariner's log slate, used for temporarily recording the route, after which the details could be entered in the ship's log, and the actual course plotted on a chart. The U.S. patent, by Francis Shenton (1826-1897) of Slatington, Pennsylvania was for "Improvement in Joints for Slate and Other Frames, employing especially secure notched joints in the construction", per Tesseract catalog 98.
