but on the west, near its contact with the granite, only 5°. It is 
singularly and fantastically contorted on the small scale, and consists 
of alternate layers of quartz and mica, of various thickness. 
§ 24. From hence, this rock crosses Glenisloreane, above Powers- 
court waterfall, ascending Djouce, and constituting its summit and 
the whole of its eastern part. The northern and north-western sides 
of this mountain consist of granite, where this rock comes to the 
surface in several places^ and by a shoulder in the northern part it 
is connected with War-hill, also composed of granite. 
On the top of Djouce, the mica slate projects in several places, 
forming a kind of crest, and it re-appears lower down on the north- 
eastern side, ranging 25° north of east and south of west, and dip- 
ping 16° toward the south-east. At the summit it is greatly con- 
torted, containing a large proportion of quartz, frequently in discon- 
tinuous masses, yet arranged parallel to the laminas of the mica. 
From this point, the view is most extensive and magnificent, being 
bounded to the north only by the coast of the county of Dublin, 
(but in clear weather reaching even to the picturesque mountains 
of Morne, in the county of Down), to the south by Lugnaquilla, 
while to the west the eye finds an outlet through the opening made 
in the mountains by Sallygap, between Sorrel-hill on the south, and 
Seefin on the north, extending to the range of hills near Kildare ; 
and to the east, we command the county of Wicklow on this side, 
with Tara-hill and part of the county of Wexford beyond. On a 
fine day the view stretches across the Irish Channel, being limited 
only by the mountains of North Wales, which, under favourable 
circumstances of weather, are indeed visible from most parts of this 
coast. 
Djouce throws out an arm to the north-east, and a longer arm to 
the south-west, the former descending into the beautiful scenery of
