On that walk I just posted about, there were many adits, and it was clear that the hillside was full of hidden tunnels. So I decided to draw a cross-section through the walk. I've uploaded the large version a bit larger than normal as there is quite a lot of small detail, although unfortunately the camera has lost focus a little at the edges so you may not be able to make out the gentleman taking a bath, whose job it is to ensure that the goblins don't get out and misbehave.
In other news, Ruggie went off to his new home yesterday, and I just got a happy email from his new owners saying he has settled in beautifully. I'm sure he's much happier in a bungalow, and he clearly was delighted with his new Golden Retriever lady friends, who are so much easier for him to keep up with than the lurchers!
