Lown This lagoon is stratifying Cregmans, 261 shale bypid, palcata, Next higher in the lower, Scotland, 36 ft. thick. It in a series of thin red did sandy limestone derived of the separation when less by shale goes. regulating charts as one sees about Cumberland, & maeriflora is very common on lown 10 ft. It has here a decided tendency to set down into a porous and residual clay sandstone with the fossils as pseudomorphs. Then the Beeragh 65 ft. thick. These are diagnostic deep red beds below for about 16 ft. full of chart. Then a zone of thinner beds separated by shale gives the whole arching much into residual clay and chart, 25 ft. thick. At the top are other beds like these below about 20 ft. thick. Towards the top the lds has considerable some quartz pebble. The Duffer Christany is at the slope down to the stream- Thickness not determinable here. It is a sandy dense thin bedded light blue limestone. At least 10 ft. can be seen. The detailed contact with the Beeragh we did not made out to see if it is diogen prone. The top of the Duffer Christany may be seen at the water reservoir on the hill above the railway. It is thick bedded hard grey arenaceous limestone with many fossils. Dav R. vroids, I. arenosus, I. arretius, L. latellite, Meta. Kasina physidata, and many others. The thickness may be between 20 and 50 ft. At the top is quartz pebble conglomerate.
