The Carey Mill division of the coal is now the only unknown part, 

 and the object of giving those borings is to afford all the information to 

 be had to miners who may be inclined to make further trials in it. Mr. 

 Dunsmore's borings having never been published, and the positions de- 

 termined, I consider them worthy of printing. 



The following is the detail of his trials in the Carey valley. They 

 have as yet only been made in the lands of Brackney, which is situated 

 a mile and a half south-east of Ballycastle. PI. XXIII. is a map of 

 this and the adjoining townland of Drumahitt, and is a copy on the 

 same scale (six inches to the mile) from that on the Ordnance Map 

 of Antrim, Sheet 9. Having ascertained the exact position of Mr. 

 Dunsmore's borings on the townland of Brackney, a mile south-east of 

 Ballycastle, I marked and numbered them on a copy of the Ordnance Map 

 of Antrim, Sheet 9, from which the map on PI. XXIII. is copied. The 

 numbers 1, 2, 3, 4, 5 on the map correspond with the numbers at the 

 head of the several borings which are given in the text, showing the 

 nature of the rock bored through at each place. It will be observed, 

 that in the last item but one of No. 1, he met coal, burned, 4 ft. 6 in. 

 This bed may be near a whin dyke, and reduced to cinders, like many 

 others in the same collieries, and might become a valuable bed a few 

 yards off; but from not meeting it in the borings, Nos. 2, 3, 4, it ap- 

 pears not to be extensive.
