A warm and humid evening, so decided to wear cotton overalls, anticipating the cave would be dry enough...and it was!
There are cows in the field with young, and a wary eye was kept on the bull, in truth they hardly noticed me as I strolled up to the stile.
In the cave, 6no. holes drilled to loosen rock in the floor at the west extent of Merlin's, where the passages appear to converge. A bit awkward clambering over the stash of bags left-over from the weekend, but job done.
The conclusion shook a pheasant of its perch, I could hear flying away in alarm. The frogs are still in the entrance.
