AT the Myall United Gold Mine, New South Wales, we crush and amalgamate for the low sum of 1/10 per ton, the ore not being handled from the time it is dumped into the ore bins till the tailings are delivered to the cyanide works. One great saving, not generally seen in Australian mills, is effected by means of automatic feeders. The kind used at Myall is the Challenge Ore Feeder. Sometimes one hears disparaging remarks made about these apparatus, but this is generally from those who do not trouble to modify it to suit existing conditions. Two weak points in this apparatus as supplied to the public, are the rapid and irregular wearing down of the rubber buffers and the variable feed. The former is due to the want of a support for the rubber when it comes in contact with the feeding disc, and to the vibration of the tappet rod; the latter to the revolution of the rod when forced round by the circular motion of the disc. In some batteries wooden or iron buffers have been substituted for those of rubber, but they are too rigid and have not the spring of the rubber ones.
