rockv island of the Iron Pot, which exhibits the same 

 character on a small scale. 



The greenstone axes generally trend north and south, and 

 the marine beds invariably quietly repose upon their bases, 

 or abut against their slopes up to a height of from 300 to 

 400 feet. In the northern part of the island sandstones — • 

 red and brown — immediately succeed the mudstones, and 

 correspond with them in the dip to the west. The position of 

 these sandstones have not yet been ascertained satisfactorily. 



Adventure Bat. 



In Adventure, near Quiet Corner, the lower coal measures 

 occur resting conformably upon the marine grits and sand- 

 stones of Upper Palfflozoic age. There appears to be no 

 stratigraphic break between the two groups. On the northern 

 side the dip of these groups is from 10° to 15° due south. 



In traversing the coast line from the Sandy Neck to Quiet 

 Corner the following rocks crop up to tho surface in stair- 

 like ledges, remarkable for their regularity : — 



FOE ABOUT 



1. Marine gritty conglomerates and indurated sand- 



stones and mudstones, in which there are at 

 rare intervals thin bands containing the fol- 

 lowing fossils sparingly, viz. : — Spirifera Strze- 

 leclci, S. Darwinii, Peterinea macropteras 

 silicified trunks of a fossil conifer of great 

 size 



2. Similar beds, apparently devoid of fossils 



3. Band of indurated carbonaceous shales 



4. Laminated sandstones, white and red, with ripple 



marks 



5. Sandstones and black and grey carbonaceous 



shales .. 



6. Grey shales and laminated sandstones in their 



beds _ 



7. Brownish coarse sandstones, with false bedding, 



evidently formed by iEolean agency 



8. Bosses of sandstones, at intervals similar to 7, 



but dipping more abruptly to the south-east... 



9. Whitish sandstone, evenly and more horizontally 



bedded ... ■•• . ••• 



10. Long sandy beach, low-lying coast, continuing to 



Bennet's Corner, where the greenstone slopes 



of Fluted Cape are reached 



It is in the neighbourhood of No. 5 where the coal seam 

 worked by Mr. Zschachner occurs. I was greatly surprised 

 to find that the carbonaceous group at this place belonged 

 to the lower coal measures, for the prevailing impression 

 hitherto was that all the coal measures of the south and east
