The road from Shelf ord to Leigh Road (Bannockburn) traverses 

 these sandy beds for the whole of its twelve miles of length, with 

 the exception of a small patch of basalt at Teesdale, and a narrow 

 flow, about a quarter of a mile wide, which passes down Stony 

 Creek. To the southward this flow is continuous with that at 

 the Inverleigh Racecourse, the low bluffs on the river bank east 

 of Inverleigh, and so on across the Barwon south of this, till it 

 merges in the wide basaltic area about the foot of Mount Pollock 

 and the sandy plateau of Gnarwarre. 



The sandy beds to the east of Stony Creek on the Teesdale- 

 Bannockburn Road, are marked as younger tertiary on Everett's 

 map ; but there seems no good reason for the different colouration 

 on the two sides of the Stony Creek coulee. This flow is only a 

 very thin one where the Teesdale to Bannockburn Road crosses 

 it, as evidenced by the fact that it usually supports a similar 

 gi'owth of trees to that which the sandy beds do, or, in other 

 words, the roots pierce the basalt to reach the sands below. 

 Besides this there are several bracken-covered patches of sand 

 which rise slightly above the basalt which surrounds them. So 

 far no fossil evidence of the Kalimnan age of the upper part of 

 these beds has been found, though we have searched near 

 Bannockburn and Murgheboluc. The underlying beds yield a 

 Balcombian fauna at Murgheboluc and Native Hut Creek, as 

 will be shown in the sequel ; but we believe the superficial beds 

 to belong to the younger series, though, it must be admitted, on 

 very slight evidence. 



The present paper deals more particularly with the sections 

 of the Balcombian beds displayed along the course of the Barwon 

 from Inverleigh to Pollocksford. These occur on the faces of 

 the gorge cut by the stream, and are not indicated on Everett's 

 map, with the exception of the one below Murgheboluc. Even 

 had they been noticed the small scale of the map would have 

 prevented their indication.

For about a mile and a half above the bridge on the main road 

 the river flows close along tiie foot of the plateau to the north of 

 the tow'Mship, with the result that numerous small outcrops of
