6() Harris and Crawford: 



striking slightly west of north, and dipping west. Then in the 

 river, sandstones and brown rubbly mudstones are exposed, un- 

 fossiliferous, but seemingly of the Grit series. Further south, at 

 the bend from south to east, north of Ba 64, a heavy fossiliferous 

 Grit band crosses the creek, dipping west, and forming a small 

 waterfall. Below it are conformable rubbly mudstones and 

 shales, and then, after a space, we come to the Dicranograptus 

 shales of Ba 64 striking almost clue north, and dipping steeply 

 to the east. 



Ascending the valley cf Evans Creek, the first rock exposed 

 is an isolated exposure of grit, apparently the projecting top 

 of an almost completely buried grit band. About 500 yards up 

 from the river an easterly grit band crosses Evans Creek. 

 Upstream from this there are numerous sandstone and shale 

 bands, but no fossils were obtained from any of the sandstones, 

 although there seemed to be no unconformity between them and 

 the Grits to the east. A little over a mile upstream, the charac- 

 teristic Dicranograptus shales appear. The shales in the interval 

 are so interstratified with hard sandstones, that no detailed ex- 

 amination of them could be made. Diplograptus and Glosso- 

 graptus were obtained from one band. 



This area again gives no information about beds overlying 

 the Grits. In the apparent syncline between the two Grit ridges 

 the shales which there seem to overlie the Grit bands are most 

 likely portion of the same series. 



(Hi.) Conglomerate Creek. 



At the junction of Conglomerate Creek with Riddell's Creek 

 Grits and Diplograptus shales are seen to underlie the Conglom- 

 erate. The Grits here lie above and to the east of the shales 

 which yielded Diplograptus. In spite of the differences of strike 

 and dip, it is possible that the shales here may belong to the Grit 

 series. The shales dip east, and strike N. 10°W., while the Grits 

 dip west, and strike N. 10°E. A band of Grit with the same 

 strike runs up the slope towards the house on the spur, while 

 further east are arenaceous shales. (See Fig. 3.) 



(iv.) Bracken Gully. 



In a small gully west of Conglomerate Creek Grits appear to 

 pass under the Kerrie Conglomerate. The Grits outcrop in the 

 floor of the gully. As the stream is followed northwards, a
