measures at Murlogh Bay are lower in the sequence than those next 

 to Ballycastle. 



The Carey sub-division of this coal-field is separated from the shore 

 collieries on the north, by the high ground, or watershed between the 

 shore and the Carey Eiver, and on the south it is bounded by the mica 

 slate of the Ballypatrick mountains. It is between three and four 

 miles from Glenshesk eastward, and a mile from north to south, hav- 

 ing the Carey Eiver running westward through the valley a good part 

 of the way. 



The country adjacent to the shore is nearly all covered with a sandy 

 drift, from six to ten yards in thickness. The stones in the drift are 

 white limestone, trap, coal shales and sandstones, and a small proportion 

 of mica slate. There is but very little rock visible in it. The junction 

 of mica slate with the carboniferous system is visible on the south side 

 of it, in the Glenmakeeran stream, at the east boundary of the townland 

 of Ballynagard, a mile and a quarter S. E. of Carey Mill. White sand- 

 stone, black shale, and red sandstone, are seen at this place witb a dip 

 of 30° N". lying unconformably on mica slate. Here there is also a 

 whin dyke ; another at the bridge near Carey Mill, and a hummock of 

 trap, apparently a part of the same mass fifty perches east of the mill. 

 The miners say that these three protrusions of trap are in a continua- 

 tion of the dyke, called the Great Gau, which is ten yards wide near 

 Bath Lodge on the shore ; but this may be doubted. Whin dykes are 

 plenty hereabouts, and to say that one rock of trap is a part of another 

 seen a mile off, and none to be seen between them, is too great a dis- 

 tance, in a country where there are often half a dozen of them in a 

 mile. 



From there being no rocks visible, no account can be given of them 

 from personal observation. The best that can be done is to record the 

 borings made in this valley by Mr. Brough, an experienced mining- 

 engineer in 1817; and to give the result of some trials of a similar 

 kind made by Mr. John Dunsmore, an experienced miner sent there by 

 the Lord Chancellor, in whose care the estate is vested at present. Mr. 

 Dunsmore kindly allowed me to copy his notes. 



Mr. Brough made several borings in the Carey valley in search of 

 coal. Of these Sir Bichard Griffith, in his Eeport of the Antrim Coal 

 District, gives us the details of four trials, which he got from Mr. 

 MacNeill, who was manager of the colliery at that time ; but although 

 he prints the results of these trials, he gives no map to show the posi- 

 tions of them on the ground, nor any other means by which those posi- 

 tions can be accurately determined. It is, therefore, necessary for the 

 benefit of persons that may be concerned in the mines hereafter, to have 

 this part of his Eeport revised. To show the necessity of this, in page 

 75 of the Eeport, the boring No. 4, in Drimadoon, is said to be three- 

 quarters of a mile south-east of No. 3, in Barnish, and immediately 

 north of the road. I ascertained the spot where Mr, Brough' s trial in 

 Barnish had been made, and I found that the nearest part of Drimadoon 

 on the road side to the site of the boring on Barnish is a mile and a quar-
