At this point the boring was stopped, as it was obviously of no use 
to sink in search of coal below the Carboniferous Limestone. The 
discovery of this limestone is an important addition to our knowledge 
of the geology of the north of the island. 
III. Bortne No. 2, ar BALLAWHANE. 
The next boring, in passing north-eastward along the coast, is at 
Ballawhane, near Blue Point (6-inch Map No. IJ), at a distance of 
about 1400 yards from Lhen Moar. It yielded the following
