ANOTHER GOLD-SAVING MACHINE.

A description of a new gold-saying machine, invented by Mr J. Carter, a Goulbum machinist, and working at Long Tin Gully, about 25 miles distant from that city, appears in She <l 'Town and Country Journal.” The treated stuff was both alluvial and clay, the formeo yielding very fine flaky and floury gold, in patches. ...principle of the gold saver is very simple-and -it woi'ks upon either wet or dry stuff. ..'-The whole arrangement is fixed in a stout framework of timber about sft high by about sft wide, and 3ft feet deep. In working order the machine weighs between iewt and scwt; all the parts are bolted together . ,by screw bolts. In working, the stuff is shovelled into a hopper, through which it falls within a rapidly revolving circular screen which is graded to pass through the stuff in three sizes. First the fine stuff goes ' throtigh the screen, and falls upon a ripple • table, which has a most effective shaking and downward-motion. The next sized coarser falls upon a second ripple table, having a f motion similar to the first. Larger stones, pebbles, &c,, are discharged from the end of the screen, and are carried away by a spout into a heap separate from the finer stuff. . ‘First the machine was tested with dry dirt, and the rapid shaking seperating motion was so effective that when the stuff was ■washed and panned off after the trial, all the speps.of gold had been saved in the riples of the shaking, table. No a spec of gold was ' ■ ' found in the tailings, although they were , -pinned off very carefully. The dry test was, therefore, very satisfactory. In the wet ' process, water was discharged from jets »i upOriihfe hopper, and also upon the screen below. The action of the machine was then very rapid, considering its size, and that the power of one man only was used in turning - .the, machinery'. With what was evidently ordinary .working, a load of stuff, just as wheeled up from the workings, went through in less form 20 minutes. The stuff from the ripples and also from the blanketing of the ripple table was then wased off into a bath, / and finally panned off in the ordinary way. The gold is very fine and flaky. In all, there may •be about, a pennyweight of it from a washing. Prom the tailings not a spec of gold was gold, although the washing was . . very carefully done. It is safe, therefore, to say, that, the machine saves all the gold that it is possible to get by separation, either wet or dry.
