We descended the rocky bank to get a better view of the great dam. Its concrete walls are so sloped that the falling water does not leave them at any point, and so an impact that would wear out the wall is avoided.

We visited the power-house, where the great pumps are busy day and night sending water to the goldfields. It took eleven days from the time the first trickle of water left Mundaring Weir for it to reach Coolgardie. While the work was nearing its completion, its successful achievement seemed incredible to the outside world. Unfortunately the inventor of this great experiment, Mr. C. Y.
