These photographs are of the monument under construction 1887-1891. During construction the blocks of dolomite stone are laid in a pattern know as headers and stretchers. The stones are cut at the site into long, thick blocks; the stretchers are laid lengthwise and the headers are laid with the ends to the outer wall running through to the inside of the structure. The joints are filled with coarse sand and Portland cement. The corner stone (thought to be the southeast corner) is seven feet long, more than two feet thick and is estimated to weigh five tons. On August 16, 1887 the Grand Lodge of Vermont Free and Accepted Masons lay the cornerstone which contains a time capsule filled with memorabilia. The image is also on display in the small gallery inside at the base of the monument.
Thank you Howard C. Ohlhous for this great history.
