AB Dissections of tree sections that contained screw rods, lag screws and bolts, and the use of the Shigometer method on living trees that have rods and screws, gave new information and confirmed preliminary data on cabling and bracing published in this Journal. When hardware is put into sound wood, the discolored wood associated with the wound is compartmentalized. When hardware penetrates decayed wood, decay spreads out to the previously sound wood surrounding the decayed wood. This reduces the holding power of the hardware. Where there is decayed wood, rods or eye bolts should go entirely through the stem and oval washers should be placed on each end.
