Passing reference has been made to the sapphire field of Anakie, in Central Queensland, and to the opal to be found in her trackless West. As a matter of fact, isolated finds of many kinds of gems besides these two have been made in widely separated parts of the State, but as a recognised branch of the mining industry opal and sapphire mining has for years occupied an important place. In the Anakie field, 190 miles from Rockhampton, on the Central Railway, the existence of gem-stones was officially reported as early as 1892. Ten years later the Government Geologist, reporting on these sapphire fields, stated that "the total distance along which deposits are found ... is altogether about fifteen miles. Of an area of 400 square miles examined, fifty square miles contain deposits carrying sapphires of more or less value." In 1905, another member of the Geological staff reported that the most important recent development had been the opening up of a second bed of the sapphire wash at a depth of 25 feet, and that excellent stones, freer from flaws than those nearer the surface, were being obtained from the lower deposit. Mining for these precious stones, many of which are of the most beautiful description, has been to a considerable extent detrimentally affected by the difficulty experienced in getting a regular market and what is considered a fair price for the gems; but, notwithstanding this drawback, there was a large expansion in the industry during the four years preceding 1907--the annual production having increased in that period from L7,000 to L35,000 in value. In 1908, however, there was a considerable falling off, mainly because miners were not satisfied with the prices obtainable; but, with an improvement in this respect, renewed activity on the field, which even now supports a population of over 1,000 persons, may be looked for.
