17. Tamlaght is three miles west of Garron Point, No. 15, and 

 along those three miles the limestone continues lowering in the face of 

 the cliff from 320 to 200, or 120 feet. An observer at Cushendall, looking 

 southward, has a fine view of the mountain face, and the outcrop of 

 the white limestone midway up, the top of it declining gradually from 

 Garron Point to Glenariff, and in its course shows an irregular outline 

 above, occasioned by the numerous faults along the line, where some 

 blocks of the mountain face stand higher than adjacent blocks, and 

 some lower; this is known by the white chalk zone, which can be 

 traced by the eye along the north face of the mountain, from Garron 

 Point to Glenariff. It is occasioned by slips or faults, which are 

 numerous in a north and south direction, pervading the mountain 

 masses, as well as east and west, which are local, along the shore. The 

 road in parts has often sunk below its level on those slipping parts, and 

 requires attendance constantly, to keep the hollows filled and the road 

 passable. The greensand here may be about 8 feet thick, of which 

 the lower three are conglomeritic, but it gets thinner as it proceeds 

 westward, so that at Baraghilly, No. 18, it is about 6 feet, and the lias 

 about 3 feet. 



18. Baraghilly Bridge, in Glenariff, is about two and a-half miles 

 south-west of Greenaghan, No. 16. The limestone on the east bank of 

 the river at this place disappears under the surface, which is 80 feet 

 above sea level. On the west bank opposite, a few yards from the 

 bridge, it stands at 150 feet. This shows a fault at the bridge, by 

 which the chalk is thrown down to the east. 



Farther west, in the same little townland, the outcrop of the lime- 

 stone is high up in the steep face of the mountain. It stands at 600 

 feet, showing that there is either another fault between this and the 

 last mentioned hummock of limestone, or that the said hummock has 

 slipped down from this latter place. "Whether there is one or two 

 parallel faults, the limestone has a downthrow from this place to the 

 bridge of more than 520 feet. The line of fault runs along the valley 

 south-west, probably near the line of the river. 



It is remarkable that the three faults in the three glens, at Glenarm, 

 at Carnlough, and here at Glenariff, have the downthrow all to the 

 south-east. These facts may be connected with some subterranean 

 movement, by which the country to the north-west, the mica slate, was 

 elevated, or the basaltic country to the south-east depressed. 



19. Kilmore is rather more than a mile north-west of Baraghilly. 

 The limestone here crops out in the mountain side high up, at about 

 700 feet. From this it continues rising with a very gradual slope to 

 No. 20, Lurrig. 



20. Lurrig signifies the end. It is so called in the country, or 

 Lurgethan on the map. It is two and a-half miles north of Kilmore, 

 and one mile south-west of Cushendall. The limestone here is the 

 highest in the whole course of its eastern outcrop, from the south at 

 Moira, standing at 940 feet. It is about 80 feet thick at this place. 

 The greensand under it is diminished to one foot.
