A NEWT STONE CRUSHING MACHINE.

The Wellington Independent says:—The new stone crusher recently imported by Mr. S. Brown* had its first trial yesterday afternoon, any one who witnessed the speed with which it crunched up huge rocks, cr uld have no doubt that it is a mechanical success, The machine, and the portable engine and boiler by which it is driven, were placed in the Ngahauranga valley by the side of the Stream, and close to an iin. inense collection of unbroken metal. As soon as steam was raised, and the machine set in motion, a pile of metal began to grow up almost perceptibly, ,aud it was apparent that it was no child’s play to keep the hopper supplied and the tail board clear. The machine finds ample employment for five men. One wheels, the large stones in a harrow to the side of the crusher, where they are picked Up one or two at a time by another man and thrown into the iron jaw—for no other word better describes tho peculiar champing noise and motion—where they are crushed into average size round metal with amazing rapidity. Such a steady stream of stones falls down the tail shoot, g the feeder at the hopper makes himself sufficiently active, that the man who keeps it clear with a shovel and the other behind him who takes the stuff away and throws it into a pile behind him, have a tolerably stiff Job. Nor was it an over pleasant one yesterday, for as each shovelful of stones was thrown to windwardbaek came a cloud of dust; ami the three men at the tail of the crusher looked as dusty as millers. The crushing apparatus is exceedingly simple in construction. The body of the machine, which is about two feet by four, is a heavy cast iron frame. One end is much thicker than the other with a serrated face. Working on an axle in the centre of the frame is a large piece of metal also serrated, and forming a box like space only a few inches widtjjat the bottom where the crushed stones fall through. This metal jaw is with a rapid.jerking motion, and if well served will crush 50 yards of metal per day. The engine is six horse power, and is constructed with the latest improvements. It is said that the inventor of the machine cleared all the expenses he, incurred in perfecting it in three months work. Judging by the above facts, Mr. Brown willno doubt have reason to be satisfied with his enterprise,
