Some Recent Deep Borings pr Water at Belfast. 8i 



the rock in a way that was quite impossible by the old jumping 

 system under which the mud, which was the resultant, afforded 

 only a doubtful means of judging the nature of the beds being 

 passed through or of fixing where one ended and another 

 began. The new apparatus has done much for science, but an 

 equal if not a greater boon would be conferred were it possible 

 to lift the core to the surface in precisely the same plane in 

 which it stood when parti of the parent rock. With present 

 mechanical apparatus this is impossible. If a method can be 

 invented for doing this, the dip of the beds, at various levels 

 and depths shown on the cores, but now of no practical value, 

 could be at once utilized and sections prepared which would 

 have not only an interest for geologists but a value for the 

 merchant, the miner, and quarry owners. 



The following are notes of the most recent borings made in 

 Belfast and its immediate vicinity, and all, with the exception 

 of No. 13, were at points only slightly above ordnance datum 

 and were in the Bunter Sandstone. 



I have often wished that there was some official of the city 

 instructed to collect and register all the details possible about 

 the borings that are being made, marking the position of each 

 on the large scale maps with a number or letter corresponding 

 with his book, valuable information would thus be stored for 

 the benefit of the citizens at a trifling cost. 



Recent Deep Borings for water— 



1. At a place now covered by Bread Street, on the Bloomfield 

 estate, and situate about 200 yards from Beersbridge road. A 



6 inch boring was carried through 308 feet Bunter Sandstone, 



7 feet of hard rock, and 39 of soft rock, total depth 354 feet. 

 Water rose 8 feet above surface of ground but was found un- 

 suitable for raising steam. 



2. Irish Distillery at Connswater, 6 inch bore 460 feet through 

 Bunter Sandstone, 4 inch bore for 65 feet further, in all 525 feet, 

 only a trifling quantity of water, moderately hard and fresh. The 

 last cores brought out give strong indications of the Bunter 

 series being pierced where it thins out upon the carboniferous
