at Blanc D'arm, i.e. red sandstones, craze and more often crampy. Ostlithus fring is seen at almost all levels. In the back part of Fortean Bay (probably 1/2 mile from the back shore) the red granite again appears at the surface. He estimate it to be 3 1/2 miles in a straight line from here to where we saw the coral reef within 30 feet of the sea. If we accept Zopans dip of 60 feet to the mile then where the granite comes to the surface in Fortean Bay the coral reef should be above the sea 25-7 feet which is probably so feet higher than the actual occurrence. A dip of 50 feet to the mile seems to be more correct. Further back in the bay to the north of the village the dip is certainly greater but it is possible that this is due to local flexure rather than a continued steepening of the dip to the north. The Archaeogatherine reef maintains its reef character seen at Blanc D'arm all the way to Fortean. It has the true coral reef structure only that the hemmolds are not so pronounced as in later Coral reefs. Between the lumps there may be a little calcareous shale and at various levels the sediment may again assume the regular stratified or bedded character. One can get better specimens of the layer form here than at Blanc D'arm. Then too one sees more often Putorisina criculate, among the corals. During the storms we had at Fortean before supper we star
