Geological Relations of the East of Ireland. 183 
little north of the lake, where blocks of that rock and of mica slate 
begin to appear. 
The granite base breaks forth again in Carrigburn and Camorus 
hills, situated to the north-west of Forth ; and blocks of granite 
are strewed over a part of the country, extending toward Bannow 
on the south. The clay slate in the southern part of the county, 
spreading toward Fethard and Bagenbon headland, (on which 
Strongbow formed his camp,) ranges in general 30° south of east 
and north of west, with a dip of 75° toward the north-east ; yet 
with some inflections : but in the eastern bank of the Slaney, about 
six miles up the river, opposite to Bellevue, this rock ranges 
10° north of east, standing nearly vertical, yet inclined toward the 
east of south. 
§ 75. The clay slate and quartz rocks in the vicinity of Ennis- 
corthy generally range 25° south of east and north of west, and the 
dip is toward the north-east, varying from 70° to 80°. About five 
miles to the westward, at Came, near the eastern foot of the granite 
chain, the strata range 20° south of east and north of west, dipping 
50° to 60° toward the north-east. This portion of the clay slate 
tract appears to contain several beds of greenstone ; and the bridge 
pver the Urrin stream is mostly built of this rock. Traces of the 
same rock occur also near Enniscorthy on both sides of the Slaney. 
The clay slate and quartz rock in the vicinity of this town are 
sometimes much intermingled. Vinegar hill and the craggy rocks 
stretching toward Solsborough are principally composed of the 
latter ; so also is Carrigrua (as I am informed,) situated more to 
the north-east. But the principal ranges, such as Slieve Buy, Bree 
hill, Slieve-kelter, &c. are clay slate : and quarries are opened in 
several parts of the line adjacent to the granite chain, some of the 
best slates being raised in the neighbourhood of Newtownbarry,
