NOVEL GOLD-SAVING MACHINE,

The following description of a goldsaving apparatus in use in Nevada is from the San Francisco Ballentin: — " There are two recent inventions being tried in Grass Valley with the end in view to still better save the gold from the tailings which run off from the stamps of the milL One of these we witnessed in operation at Perrin's mill, on Wolfe Creek. This invention consists of an application of the grist mill to quartz tailings. The stones are of common granite, the upper one revolving just as in a flour mill. MonsChabrol's machine at Perrin's mill grinds twenty tons in twenty four hours and does its work welL The wear of the granite used amounts to an expense of about one dollar per day. We have no figures as yeb of the value of the gold saved by the grinding process, but we learn that the remuneration is unexpectedly large. In the case of the machinery in question, the tailings are ground after tke sulphui-ets have l>een separated, or in other words It is at work on the sand which is ordinarily allowed to run into the creek. Another grinder of a different kind is at work on the east portion of the town, on sand which came down from Wolfe Creek. This sand is made finer, and is then run over amalgamating machinery. Ihe results so far have been good. These simple machines demonstrate that a large amount of gold has been allowed, heretofore, to run off with the water of the creek to be finally deposited in the rivers and the valleys."
