With West Torr may be put a detached piece of white limestone, 

 which lies to the east of Carnlea, presenting nearly the same character. 

 It runs nearly parallel to the shore, opposite Loughan Bay, between 

 Torr Head and Runabay Head. It is two miles long, half a mile wide 

 at the north end, and the southern half of the length is about a furlong 

 wide. Like West Torr, No. 35, it is not covered with basalt, but in 

 both the pasture is kind, green, and close, and the soil good for tillage, 

 thus presenting a remarkable contrast to the herbage and soil of the 

 great table land from Knocklayd eastward to the sea, which is covered 

 with bog and heath. This limestone district is from 500 to 600 feet 

 high, and this circumstance points to the probability that the whole is 

 a downthrow, from Carnlea, of the chalk and its supporting mica slate. 

 The line of this downthrow may be in the bed of a stream which runs 

 north-east towards Torr Head for a mile. From the upper end of this 

 mile it turns south-east by the valley of Ballinloughan, and continues 

 to the townland of Torcorr, near Runabay Head. On the east of this 

 district, new red sandstone appears under the chalk, as in Murlogh 

 Bay. There is none visible on the west, this fact further suggesting the 

 probability of the existence of a fault on the west side, along near the 

 edge of the chalk, in which fault the new red sandstone lies buried. 



36. Larrybane Head (from Lair Ban, the white mare). I select 

 this locality as worthy of note, because the perpendicular sea cliff here 

 is white limestone from the top to the bottom. Some yards inland from 

 the shore there is an Ordnance Survey height of 168 feet, and as the 

 beds are quite level here, this may be taken as the least thickness of the 

 limestone, for there is some of it under water. 



I should not pass this locality without making reference to Kenbane 

 Head, two miles east of this station, because at this place, more decidedly 

 than on any other point on the coast, the relations between the trap 

 and chalk can be observed. A large piece of chalk, as it lay in its bed, 

 apparently in a plastic state, has been separated from the rest of the 

 mass below it, and doubled up into the form of a high arch, leaning to 

 one side (the west). The bedding in this mass is known at a distance 

 by the lines of flints in relief which appear on the face of it. It appears 

 pushed up at one abutment, if I may so call the end of the arch, and 

 much shattered at the other, many of the fragments being enclosed in 

 the surrounding basaltic matter, which appears to have insinuated 

 itself into every crevice that was open to receive it. These masses of 

 imbedded chalk have all been altered more or less where they are in 

 contact with the trap (see Pig. 3). 



37. Ballintoy village is near this place, No. 36. The limestone is 

 under the street, which there measures 202 feet above sea level. 

 Although the fields are covered with soil, and therefore the rock not 

 visible, there is every reason to suppose that the beds are level under it, 

 from Larrybane Head to this, and if so, the chalk is above 200 feet thick 

 at the village of Ballintoy. 



At the top of the cliff at Whitepark, a mile west of Ballintoy, two 

 estimates were made of the thickness of it, the one made at the east
