An overturned rock which Natalie d'Arbeloff describes as:
an unremarkable pinkish-grey object about four inches wide presented itself and allowed me to flip -
or, more accurately, kick it - out of its comfortable hole for the necessary photographic evidence.
I could not detect any activity underneath but I suppose if I had poked around the hole a bit deeper
there might have been the odd worm or ant but by that time I was hungry and the cafés at the top
of Swains Lane beckoned.
