another men that is of 15' thick. The ls are all of the lenticular hue-white and bridge-like. Some of the pieces are up-crust 5' long and 1/2 Mallett-like dol.
I saw one lump 3' across. The paste is a smoky dull orethly rusty red.
Then crawled across the fields south to the most treasured road (now very gone) and for got to be called and looked at the true small blue-white lenticular from me of which I got from men earlier trip. The layer is about 30' long, but the two each about 20' across. They are just uncovering out of the Highgate slate. Some of the slate miners saw a piece of the lenticular me first by showing but the projects above the sea bottom as that piece broke off and turned in the ground.
There is not the slightest doubt about these lenticular being in the Highgate slate and over all the face of the series.
Down again on the top of the big lenticular opposite the same road, it is 180' E-W by 120' N-S. May 10-12 thick. Torn along two pieces to make section up, but what's diagonal has changed all structure. It also has occasional grains of quartz sand.
