At that time the existence of artesian water in Queensland was no more than suspected. It had been tapped four years previously in New South Wales, but the boring appliances were so inadequate as to make the process tedious and of questionable practicability on an extensive scale. In Queensland some prospecting work had been done, and in some places fair supplies of water obtained by sinking ordinary wells. But in the Far West there was little scope for enterprise in that direction. Hence some extensive dams were constructed across watercourses ordinarily dry, but without conspicuous success. For often the rush of flood waters either carried away the embankments, or the reservoirs they created quickly silted up, or the porousness of the subsoil could not be entirely combated by "puddling." Then streams at times complaisantly abandoned their old channels and formed new ones, leaving the intended reservoirs high and dry after the most deluging rains. After a time it was found that better sites than the beds of main watercourses could be found for dams, and that the construction of tanks would suffice in many places to provide sufficient water for a scattered population and the increasing numbers of live stock, although the expense of this mode of conservation was great for the limited supply obtained. Evidently, if the Far West was ever to be completely utilised, its almost illimitable areas of splendid pastures must be watered by some more effective means. Attention was at this time attracted to the success of the few artesian bores in New South Wales, and to the vast scale on which water had been tapped by that means in the United States of America. The chief obstacles, however, were the great depth at which artesian water might be expected to be found, and the utter inadequacy of the boring machinery then in use in Australia; moreover, the search was most needed in the areas practically inaccessible by reason of the absence of surface water. For a considerable time, as is disclosed in the digest of the Hydraulic Engineer's annual reports reproduced in Appendix H, little progress could be made.
