Fingal and East Coast. 45 



from where the road crosses the tier or range of green- 

 stone hills separating the valley from Swanport. 



In the valley of the South Esk it is scarcely to be met 

 with, from the confluence of that river with the St. 

 Paul's at Avoca to its junction with the Break-o'-day 

 beyond Fingal. Nearly opposite this latter point it does, 

 however, make its appearance upon the southern side of 

 the valley ; and soon after it is found opposite to Killy- 

 moon, the residence of Mr Stieglitz, rising several 

 hundred feet into the bosom of an amphitheatre of green- 

 stone hills, at the very point of which crinoidal limestone 

 and a superjacent ferruginous grit crop out in the floor of 

 the valley, arguing the probability of a considerable dis- 

 placement in the intervening carboniferous group of beds. 



Greenstone obtains exclusively from this locality to a 

 point nearly opposite Mr. Legge's farm, where the brown 

 sandstone is found extending continuously from an eleva- 

 tion of several hundred feet to the level of the plain, 

 characterised, as usual, by its structure, colour, and con- 

 tents of fossil wood, casts of plants in anthracite, and 

 thin and very limited seams of lignite, and jet-like but 

 incombustible coal, &:c. 



The same beds rise to a nearly equal elevation due 

 south from Mr. Groom's residence, at the north-eastern 

 extremity of Break-o'-day Valley ; and still, as before, 

 cut off and capped by towering masses of eruptive 

 rock. 



Upon the flat-topped hill called Thompson's Big Hill, 

 or the Elephant Hill, a short way south from St. 

 Patrick's Head, and about three miles east from Mr. 

 Groom's house, this overlying sandstone is raised to a 

 height of 800 to 900 feet, upon which, as usual, there 

 rests a cap of greenstone some 300 or 400 feet in thick- 

 ness. The sandstone dips here to the north ; and the 

 limestone, which crops out about 250 feet above the
