Wednesday Sep. 19 - 1934 one around out, and these pieces are of the Tunbridge Wells Slate, the basal Sandstone, and blocks of the Lichfield Mercia-Sandstone. It is now clear to me that this sandy drl. belongs to the Carboniferous, and is only another formation. These basalt beds can be seen al- most the entire length of the farm north to the mine face and beyond some hundreds of feet. It shows one thin bedding and on the most northerly farm an irregular folded like contact. In other words, the veins were strong cracking through the sand and the Lower Lichfield Slate Limestone (whose source is an unsolved problem) and small lentils or pieces of layer ones. Be- tween all the pettles and tricea pieces the Friday matrix is a crasse sandy drl. Reginald says the tillities have an older aspect than the Sauge formation, Curious but only this should be on must be looked once into.
