During the next six days Lady Taieri gave a series of magnificent entertainments. There were dances, dinner-parties, picnics, a visit to the glacier region of Mount Cook, and finally a ball in Dunedin of unsurpassed splendour. This was on the eve of the opening of the river-works; and all the authorities of Wellington, including the Governor and his Ministers, honoured the ball with their presence.
An account of the river-works will not be unacceptable. So long since as 1863 it was discovered that the river Molyneux, or Clutha as it was sometimes called, contained over a great length rich gold deposits. More or less considerable quantities of the precious metal were obtained from time to time when the river was unusually low. But at no time was much of the banks and parts adjacent thereto uncovered. Dredging was resorted to, and a great deal of gold obtained; but it was pointed out that the search in that manner was something like the proverbial exploration for a needle in a haystack. A great scientist, Sir Julius Von Haast, declared that during the glacial period the mountains adjacent to the valley of the Molyneux were ground down by the action of glaciers from an average height of several thousand feet. Every ounce of the pulverised matter must have passed through the valley drained by the river; and he made a calculation which showed that, if the stuff averaged a grain to the ton, there must be in the interstices of the river bed many thousands of tons of gold.
Nearly fifty years before the period of this history the grandfather of Hilda and Maud Fitzherbert set himself seriously to unravel the problem. His design was to deepen the bed of the Mataura river, running through Southland, and to make an outlet to it from Lake Whakatip. Simultaneously he proposed to close the outlet from the lake into the Molyneux and, by the aid of other channels, cut at different parts of the river to divert the tributary streams, to lay bare and clear from water fully fifty miles of the river bed between Lake Whakatip and the Dunstan. It was an enormous work. The cost alone of obtaining the various riparian and residential rights absorbed over two millions sterling. Twice, too, were the works on the point of completion, and twice were they destroyed by floods and storms.
Mr. Fitzherbert had to take several partners, and his own enormous fortune was nearly dissipated. He had lost his son and his son's wife when his grandchildren, Hilda and Maud, were of tender age. After his death the two girls found a letter from him in which he told them he had settled on each of them three thousand pounds a year and left to them jointly his house and garden near Dunedin, with the furniture, just as they had always lived in it. Beyond this comparatively inconsiderable bequest, he wrote, he had devoted everything to the completion of the great work of his life. It was certain now that the river would be uncovered; and if he was right in his expectations, they would become enormously wealthy. If it should prove he was wrong, "which," he continued, "I consider impossible, you will not think unkindly of the old grandfather whose dearest hope it was to make you the richest girls in the world." The time had come when these works, upon which so much energy had been expended, and which had been fruitful of so many disappointments, were to be finished; and a great deal of curiosity as to the result was felt in every part of the Empire. Hilda and Maud Fitzherbert had two and a half tenths each of the undertaking, and Montreal and his younger brother had each one tenth, which they had inherited, but it was understood that Montreal had parted with his own share to Colonel Laurient; two tenths were reserved for division amongst those people whose riparian and other rights Mr. Fitzherbert had originally purchased; and of the remaining tenth one half was the property of Sir Central Vincent Stout, Baronet, a young though very able lawyer, the other half belonged to Lord Larnach, one of the wealthiest private bankers in the Empire. There was by no means unanimity of opinion concerning the result of the works. Some people held, they would prove a total failure, and that the money spent on them had been wasted by visionary enthusiasts; others thought, a moderate amount of gold might be obtained; while very few shared the sanguine expectations which had led old Fitzherbert to complacently spend the huge sums he had devoted to his life's ideal. 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.
At a quarter past one o'clock the guns pealed forth; and loud as was the noise they made, it seemed trifling compared with the cheers which ran up and down the river from both banks from the throats of the countless thousands of spectators. The announcement of success occasioned almost delirious joy. It seemed as if every person in the vast crowd had an individual interest in the undertaking. The telephone soon announced that at a turn in the river about seven miles from the lake what appeared to be a large pool of fine gold was uncovered. Even as the news became circulated there appeared in the middle of the river right opposite Lady Taieri's stand a faint yellow glow beneath the water. Gradually it grew brighter and brighter, until at length to the eyes of the fascinated beholders there appeared a long, irregular fissure of about twenty-five feet in length by about six or seven in width which appeared to be filled with gold. Some of the company now rushed forward, and, amidst the deafening cheers of the onlookers, dug out into boxes which had been prepared for the purpose shovelsful of gold. Fresh boxes were sent for, but the gold appeared to be inexhaustible. Each box held five thousand ounces; and supposing the gold to be nearly pure, fifty boxes would represent the value of a million sterling.
Five hundred boxes were filled, and still the pool opposite Hilda was not emptied, and it was reported two equally rich receptacles were being drained in other parts. Guards of the Volunteer forces were told off to protect the gold until it could be placed in safety.
Hilda and Maud were high-minded, generous girls, with nothing of a sordid nature in their composition; but they were human, and what human being could be brought into contact with the evidence of the acquisition of such vast wealth without feelings of quickened, vivid emotion? It is only justice to them to say that their feelings were not in the nature of a sense of personal gratification so much as one of ecstatic pleasure at the visions of the enormous power for good which this wealth would place in their hands. Every one crowded round with congratulations. As Colonel Laurient joined the throng Hilda said to him, "Why should I not equally congratulate you? You share the gold with us."
