On the opposite side of the river, and about two miles below 

 the Red Bluff, there is an eocene outcrop, which we examined 

 (Sec. I.). Here the fossils, which resemble those at Section II., 

 are sparingly distributed in a clayey matrix. They cease at a 

 height of 80 feet from the river, and are then succeeded by clays 

 and sandy ironstone, mingled with quartz pebbles. No fossils 

 were observed in the ironstone, but we have no hesitation in 

 classing it as miocene. There is no capping of basalt above it, 

 as this rock is absent from the east bank of the river from Golf 

 Hill right on to Inverleigh. Amongst the fossiliferous clays of 

 this section there is in places a deposit of powdery, cream-white 

 carbonate of lime, which, if continuous down to any depth, might 

 prove of commercial value. 



We did not examine the eastern bank of the Leigh between 

 here and Inverleigh, but at the latter place we observed a long 

 stretch of eocene clays just above the water's edge, and the 

 continuance of eocene strata all the way is therefore assumed. 

 As we drove along the western bank from Inverleigh to the Red 

 Bluff, several outcrops of limestone were noticed ; and in one 

 place, where a dam had been excavated, the same rock, much 

 decomposed, showed below the alluvium of the flat. Eocene 

 limestone also crops out occasionally, both at the level of the 

 road and at a considerable elevation on the bank between the 

 Red Bluff and Shelford. There is, however, no more clay, and 

 though fossils are certainly obtainable by patient searching, they 

 can rarely be extracted whole. The relations of these limestones 

 to the accompanying basalt and overlying miocenes are very 

 interesting ; but their discussion must be postponed till the 

 remaining eocene sections have been described. 



The next notable outcrop is just over the Shelford Bridge, on 

 the east side of the river (Sec. V.), where the incline leading to 

 the table-land on the summit of the bank has been cut down in 

 making the road, and the steep face thus formed has exposed the 

 eocene strata for a distance of about 100 yards. They consist of 

 calcareous clays, with thin bands of limestone running through 

 them. Observations of the dip of these bands were made, with 

 the following results. At the first station, close to the com- 

 mencement of the cutting, an apparent dip of 4° to east 5° north, 

 was lecorded. At the second station, ."^0 yards up the hill, and
