Although the Hydraulic Engineer, so long before as December, 1884, had recommended the Minister to import American boring machinery with men trained to work it, it was not until 19th October, 1886, nearly two years later, that he was able to announce that his advice had been so far followed that Mr. Arnold, an American borer from Honolulu, had gone to Blackall with a Pennsylvania Walking Beam Oil Rig boring machine which had been constructed in Brisbane. It seems that so long previously as July, 1885, two tenders for boring by Americans--one being from Mr. Arnold--were submitted by the Hydraulic Engineer to the Minister, with the intimation that they were both too vague for acceptance, and expressing the hope that Mr. Arnold, "who seemed a man of considerable experience, would submit a more liberal and definite offer." The same report mentions that on the 30th June previously the Blackall bore had been carried to a depth of 775 ft., and that at 127 ft. good water had been struck that rose to a height of 60 ft. below the surface, but was deemed insufficient for the requirements of the town. Up to that time nine bores had been completed, chiefly by the ineffective Tiffin auger, but not one had reached artesian water, the deepest being that at Blackall, and the average depth 371 ft. ARTESIAN WATER STRUCK AT THURULGOONA. In his report of 12th November, 1887, the Hydraulic Engineer states that it is essential that only the best quality of tubing, or "casing," should be used in bores. In April he had visited, by direction of the Treasurer, Thurulgoona Station, on the New South Wales border, and there carefully inspected boring operations. He found that one bore had, by means of the Canadian Pole Tool boring machine, been sunk to 1,079 ft., a supply of excellent water having been struck at a depth of 1,009 ft., "the water overflowing in my presence to a height of about 20 in. above the surface of the ground." This was apparently the first artesian water Mr. Henderson had seen in Queensland, though he had years previously seen the artesian well at Sale, in Victoria; and he naturally pronounced the opinion that the result at Thurulgoona was "very satisfactory." During this year boring had been carried on in Queensland without success so far as the formation of flowing wells was concerned. Mr. Arnold, having sunk to 1,039 ft. at Blackall, resigned, but it was decided to continue sinking, all the tubing being recovered with the exception of a few feet, and being capable of use several times over if need be. During this year also tenders had been received from Mr. Loughead, of Thurulgoona, to put down three bores of 2,500 ft. in Queensland, and Mr. Henderson reported that there was every prospect of a tender being received from a company recently formed in Brisbane at a slightly lower price than Mr. Loughead had named.
