is nothing more than Highgate Carboniferous, certain it is that the shale on each side of the Conglomerate is alike to those all of Dorset's fossils come from above the Conglomerate. Either the Conglomerate is folded into the slates or the conglomerate is one of the Dorsetian; or at once if the Dorsetian places, the shale to the east are not Serpion in the sense that they any Bunter formation age. He may have a shale here but not the Drillington and Keythorpe. The succession from St Albans Bay to Alders Poston must be repeated from the Magpie Conglomerate to the west, that where we did not see the Millton. There is a question in Raymond's mind as to whether we have seen any Millton. It maybe that the Cretaceous has dolomite goes in it. Certain it was so at Partners Ledge before we came upon the thick mass of dolomite, correlating with the Millton. Then drove to the Cretaceous locality about 3/4 mile N.E. of Dorset Junction. Here there is a big quarry for the flood shale. Dr. Raymond got a fine bit since Morner's we saw of those shales 20 to 30 feet. They so into a stiff dolomite in the face of which occurs Olivoids. Then comes in a mass of dolomite 200 to 300 feet thick that must be the Millton. Then a fault repeating the section with then more shale followed by more dolomite,
