By 10 A.M. the sky is free of heavy clouds and it looks most like rain for the afternoon. North west of Carrigal many miles one sees the very high and jagged mountains, some of which must stand up at least 4000 to 5000 feet above the main Carrigal. Between them is a vast dunality Country. The Tertiary collecting ground is towards the west rising into the higher ground. In the afternoon walked south east along the track for 2 kilometers, but the sun was on her and the air sultry that did not go further. Looking back to the higher country one sees at least two dunality shelves falling down into the low country. Farther with and over the higher lands one which we came yesterday. The topography looks like this. [illegible] Early this morning distant Dr-D.J Carrigal is stood cut calcareum then breck (limestone) rock standing away in wedge. This I take to be Cutaceums, over these Dunality aertmenconfirming the Tertiary beds with the former describer Dr Bice.
