Fiona suggested that the glass bottle shard found (and left) at the waterfront on the south shore was late 18th century or early 19th century ... so not during Macfarlane occupation. Not old from U.K. standards, but old enough from an American perspective! :-) Similar to Vassar or Yssar glass.
Photos through the east wall air vents showing what appear to be the underside of stairs was interesting and consistent with earlier analysis from the other side. (The indentation on the east wall as you enter the ruin is a stair well rather than a fireplace or cupboard as often
We have plans to update the site to break out the projects into pages and to include some more 3D rotating images. We have created one for the dressed window stone and are hoping to do more .. particularly after the trimming/preservation.
More to follow!
Thanks for your continued support!
