If I'm making an eejit of myself because I've put all this on before, so be it. I'm glad to be reminded of it anyway as it takes my mind off crap.
So the booklet has a page dedicated to a diagram of the souterrain. It shows a drawn mound, long, flattish and semi-circular (like a convex shape), and the suggestion is that at its highest point it is about 20ft. Now, the diagram's not that clear to me, but it seems as if the sod hut was at ground level in the centre of this semi-circular mound - with the mound
behind it. It gives no indication of how long the mound is, nor how deep it is. What it does seem to suggest is that floor of the cave, or souterrain, is about 12 feet
from the roof of the sod hut, meaning that it's NOT as much as 12 ft. underground. Looking at it, it seems to me the hut was 4 ft. high and under the floor of it, 8 feet down, is the floor of the souterrain.
The souterrain itself has been drawn in shape, as if looking down from above. What there appears to be is a rectangular chamber about 8 feet down (where the spade opened it) and a narrow passageway into a larger rectangular chamber. It looks like a small rectangular leading to another, larger rectangle, connected by a thin tunnel. There is no indication of what either of these rectangular chambers measure, nor the thin passage from one to the other.
However, curiously, the way it is drawn it is as if the thin passage actually goes nowhere but strikes a dead end! It is as if they
appear to be interconnecting, but don't actually connect --as if the thin passageway is nothing but a red herring and strikes the wall of the second rectangle
which doesn't have an opening! (That's a funny "store"). I can't make it out. Maybe the person who drew it didn't
mean to suggest that the thin passage didn't actually convey from the small rectangle to the larger one.
If you had 2 dominoes, one bigger then the other, and you set them down long-wise so as the smaller one is directly below the bigger one, and you cut a section of lollipop stick and placed it as per the roughly central connecting passage, assume that the passage certainly does lead away from the smaller one, but strikes the wall of the bigger domino, rather than going into it. That's the best way I can describe what I'm looking at. It's a bit odd.
