Throughout the Ord. series seen this afternoon there are many intraformational flat-pettle limestone from one to three foot thick. The flat pettles are less common in the lying sandstone, and there are none apt to be of angular limestone in size up to one inch but common of smaller. These concretion are now very westerous along the strike, some will peter out in 100 fot but more that could trace more longer than 300. They are local accumulations. In the sandstone one sees them very patchy. All the li. and so show some cross-bedding. The whole series is of very shallow water - tidal flats - and this explains why the fossils are or scarce. When present they are all diminutive
