August 19. Hawkes Bay, south shore continued. 4 fts of blue long shales followed by 14 fts of heavy hard laminated long sandstones. On one of the latter there are just the second lots of fossils. Then a deep bed of fine grained blueish arenaceous lie followed by a similar zone with Cryptogon. Then about 5 fts of laminated similar structure, followed by 15 fts more that is all that has Cryptogon, then fat once crossed semi-crystalline. Then a ridge of oxidized beds - 3 fts like before, 1/2 ft of joint shales, 1 1/2 of greenish shale, 3 fts of thin bedded arenaceous lie as before - about 9 fts topside. So this gave them some semi-oxidizing and intrusive crystalline. There may be from 10 to 20-ft more of our hard bluish to dove colored heavy headed lie. In the laminated beds we see semi-crystalline and near the top there is a thin 3 ft thick of red porous conglomerate. This takes us to the eastern side of Horse Island. As yet we have seen nowhere on the south shore any oxidized deformation. All goes in an undulatory way with dips that rarely rise to 50 or 6 degrees. Generally it is from 5 to 15 degrees. Therefore the entire thickness of L.C. along its south shore is not fresh. In a small cave, there is then an unusual infolding to the north of which appears at the foundation beneath a large calcareous line tied to the E of the Reef, once in fossiliferous Bedlmanthum dipping 20 S. 30 E. The Bedlmanthum is slightly cordiform has some intrusive crystalline and iron layers around it as the faults are common and the strata are lying at other angles lie by and chock together they are therefore hardly the basal Bedlmanthum, the line about the fault is lower than to the east. Horse Island lies to the west of the fault line and has Bedlmanthum on strike. The strike of the fault line we then returned for dinner to camp over the launched. at 1 p.m.
