limestone is found below the road in Upton demesne ; it was quarried in 

 several openings, and burned extensively there about twenty-five years 

 ago, but no lime is burned there now. In the churchyard fragments of 

 it are quite usual in digging the graves, and the labourers say that it is 

 under the soil in all the fields about the church. 



It is a question whether this chalk was ever covered with trap, like 

 the surrounding country, and afterwards denuded. As it occurs near 

 the lowest part of the valley, it is not likely that denudation would have 

 acted to such an extent as to sweep away hundreds of feet in thickness 

 of the trap, and leave the chalk exposed here. The probability is, that 

 this spot escaped being covered by the overflow of trap which covered 

 the rest of the chalk. 



"No. 9. Kilroot, near St. Catherine's, is two miles north of Carrick- 

 fergus, and six miles north-east by east from jSTo. 8. At this place the 

 character of the chalk country changes. From Aughnahough, No. 3, 

 to this, the vicinity of the outcrop of the chalk along the mountain brow 

 is steep or precipitous, but from this northward, although the escarp- 

 ments of high land still continue from St. Catherine's in a tolerably 

 straight general line, by Rory's Glen and Sallagh Braes, yet the chalk 

 here, instead of appearing high up in the brow of the mountain, runs 

 out from the base of the high land, and extends over the country east- 

 ward, declining gradually to the sea shore. About Larne Lough are 

 eruptions of basalt, which rise into pretty high hills, showing the 

 outcrop of the chalk near their bases. There is no section of the rocks 

 at St. Catherine's or Redbrow ; White Head is the nearest place to it 

 that affords one. Here there is solid chalk visible at the top, 40 feet ; 

 a sloping talus covered with fragments which rolled down from above, 

 about 30 feet; steps at the bottom, not quarried, 30 feet; total, about 

 100 feet thick. There is a bench of greensand under it, stripped about 

 50 feet long, and 6 feet high, well exposed. It appears in four or five 

 places, yet no good place occurs to measure the whole. The beds of 

 chalk dip south-west 10°. Resting on the chalk here is a magnificent 

 faqade of columnar trap, the columns 50 feet high, and curving. To 

 this I shall allude again. 



To the north of Carrickfergus, towards Larne, the chalk band is 

 much broken up. The western, or main outcrop, from Lough Mourne 

 northwards, by Kilwaughter and Sallagh Braes, maintains its high 

 level at about 550 feet. There are in the vicinity of Larne Lough four 

 other outcrops, two to the east and two to the west of that lough. 

 They all affect a southern direction, being nearly parallel to the shores 

 of the lough, and to one another. 



The first of these outcrops shows itself on the east coast of 

 Island Magee, at Black Head, near the Gobbins, and at Portmuck. 

 The second is on the east shore of Larne Lough. The third on the 

 west shore of the lough. The fourth runs in rather a tortuous course 

 from Bellahill by Ballycarry, and joins the third at Ballylig. These 

 outcrops are all, of course, on the same band of chalk as just stated. 

 Between the first and second the whole of the chalk is covered by
