Grindson, July 3-1912 Start the morning measuring the section to the south of the Dominion Atlantic Railway Bridge. The lowest part of the arch or anticline comes in about 420 feet to the south of the bridge. Here the lowest beds are the following going south along the Armon and upward in the section. 17 Green argillaceous thin bedded limestone. Thickness unknown. Top of anticline at this place. But little exposed. 18 Green shales. Thickness 32 inches. 19 Nodular layers, greenish that have more or less fossils throughout but the Productus, Composita and the Coral are most common about 2 feet from top. Actual thickness 19 feet. Have a small collection (D2900) terminates at the top in the "Stromatolitic bed". 20 Thin regular bedded green oolitic limestone 17 inches thick in the "Stromatolitic bed" = The fault much larger due to wave action. 21 Green shales, about 3 feet thick. 22 Dark brick-red sandy shales. 14 feet. Section broken here. The fault may be seen sharply along the shore of the Armon. It may be seen far better at the edge of the shore in the bluff. Near the railroad tracks appears the Stromatolitic bed at the high tide line. Here it is overturned. It is again seen in the railroad cut about 100 feet in from the Armon edge.
