THE ARTESIAN BORE.
As we mentioned in a previous issue the pipe of the artesian experimental bore in the Triangle was blown out at a depth of 460 ft. This was the deepest level at which water was obtained, but the contractor drove down to 528 ft. in order to ascertain whether another flow could be met with, but, as only sand and fine gravel were encountered and there was a risk of breaking the pipes, it was decided not to go down any further. Since the blow-out at the 460 ft. level only a trickle of water has risen to the surface and to-day Mr Chrystall has been engaged in cleaning out the pipe. He slates that portions of the insulated wire, etc.,used in the blasting operation, are partially choking the bore. He says that if the obstruction cannot be removed, the next best thing to do would be to blow out at the 230 ft, level, where the second flow was obtained. There appears to be very little hope of securing a good flow at 460 ft.
