Bearing column jack

This section of the main floor partition wall includes a bearing column with a jack that (like the king post and porch column jacks) is  adjusted in spring and fall for the settling of the walls.   The jack is shown being installed on the ply'd column which is embedded in the partition wall.    There are two of these under the white pine summer beam that runs lengthwise supporting the mid-point of the loft, it ranges from 13 inches diameter at the tip end to 23 inches diameter at the butt end.
