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.

In the same month the Treasurer received a letter from the late Hon. George King, of Gowrie Station, Darling Downs, directing attention to the "Walking Beam Rig" machine, an American well-boring apparatus, by the use of which it had been ascertained that his firm might have saved �4,500 out of the �6,000 spent by it in well-sinking in the Warrego district.

Being a staunchily built wooden boat with double "walking beam" engines, working independently, one on each wheel, she always got herself off with little trouble or damage.
