As we get into the basal beds of the Millstone Grit at the farthest southern point - about 1/4 miles south of the gypsum quarry we see again the zones of nodular limestone conglomerates seen this morning near Hard Ledge. All of these things go to show that we are on the opposite side of the anticline seen this morning by being on the northern limb near Hard Ledge. The anticline is evidently a closed one and with slight slippage goes along the northern side near the Millstone grit. At the gypsum quarry the southern dip is again of the regulative dip, about 20-35 degrees, seen or noted here in the Cumberland Basin. Evidently the line between the Joggins series and the Windon series is true drawn where the brick-red shales without sandstones and without conglomerates cease. Joggans division I is not the base of the Joggins series but far down in Div 8 beneath all of the conglomerates and nodular limestone a considerable beds. Where the brick red shales become constant those are the Windon beds, where they are conglomerates they are of the Joggins series. The latter always have Pennsylvanian Plants while the brick red shales have no plants at all.
