What is this stuff?
The situation is a shingle path running alongside an old stone boundary wall.
As you can see, there is quite a lot of moss and weedy bits within the shingle.
But what are those roundy things?
There's a huge pile of them, proportionally, just at this point on the path.
Clue: it's nothing to do with the apparent hole at the base of the wall, that's an optical illusion, and is actually just a shallow indentation between stones.
Answers on a postcard... ok, answers by email or by comment below.
And I'll reveal all, tomorrow!
