And now the result of fifty years of toil and anxiety was to be decided. It was an exceptionally fine day, and thousands of people from all parts of New Zealand thronged to the ceremony. Some preferred watching the river Molyneux subside as the waters gradually ran out; others considered the grander sight to be the filling of the new channel of the Mataura river. It had been arranged that two small levers pressed by a child would respectively have the effect of opening the gates that barred the new channel to the Mataura and of closing the gates that admitted the lake waters to the Molyneux. As the levers were pressed a signal was to run down the two rivers, in response to which guns stationed at frequent intervals were to thunder out a salute. Precisely at twelve the loud roar of artillery announced the transfer of the waters. Undoubtedly the grander sight was on the Mataura river. The progress of the liberated water as it rushed onward in a great seething, foaming, swirling mass, gleaming under the bright rays of the sun, formed a picture not easily to be forgotten. But the other river attracted more attention, for there not only nature played a part, but the last scene was to be enacted in a drama of great human interest. And this scene was more slowly progressing. The subsidence of the water was not very quick. The Molyneux was a quaint, many-featured river, partly fed by melted snow, partly by large surface drainage, both finding their way to the river through the lake, and by independent tributaries. At times the Molyneux was of great volume and swiftness. On the present occasion it was on moderate terms--neither at its slowest nor fastest. But as the river flowed on without its usual accession from the lake and the diverted tributaries, an idealist might have fancied that it was fading away through grief at the desertion of its allies. Lady Taieri's party were located on a dais erected on the banks of the river about twenty miles from the lake. After an hour or so the subsidence of the water became well marked; and occasionally heaps of crushed quartz, called tailings, from gold workings on the banks, became visible. Some natural impediments had prevented these from flowing down the river and built them up several feet in height. Here and there crevices, deep and narrow or shallow and wide, became apparent. The time was approaching when it would be known if there was utter failure or entire success or something midway between. It had been arranged that, if any conspicuous deposit of gold became apparent, a signal should be given, in response to which all the guns along the river banks should be fired.
