THE ROAD TO WEALTH.
A Machine by Which the Poor Miner can
 Get Rich.

A Machine by Which the Poor Miner ca | Get Rich.
 A few weeks ago Mir. J. F. Sander
 constructed an experimental machin'
 upon principles covered by three sep
 al ate patents held by him, and wen
 with it to the Santa Catalina mountainl
 to try i,s pra,tiesbility with the placeri
 go generally found there. He modified
 the apparatus to suit the conditions oi
 the gravel encountered and made (
 thorough test, with the most remarkable
 success. Even on the tsilings from the
 rockers employed by the miners n that section, the machine took out one dollar an hour, which attests its thoroughness in the extraction of even the finest par
 tic'es of the precIOus metals.
 Satisfied with the result of his exper- imeuts. Mir. Sanders returned to this city and bas just completed larger ma chine and VIII proceed at once to the mogutsIns Co start up work, accOmpa- niel by Mir. II. c. SieSiried and another gentleman.
 Briefly de.csibed. the machine which is a simple gmslgamstor and concentra- tor combined, is as follows; A wooden bed. Rbuut four by eight feet in size, IS held above the sills of the frame work oy four upright supports, permitting an Oscilisting motion lengthwise, with a sligtt rising motion towards fhe head as She vibrations are given it by re. voiyiaC cam A copper amslgsmating pla.e covering about twO-iifths of the bet, IS placed at its upper end, termina- ting in a sunken recess rifle, and the remaining part of the bed has several cross rillss to retain all heavy metals encountered. ns well Gs the black sand.
 x. tEe Lead of the machine IS a v shape receptacle for the gravel, with one side several inches lower than the other. Into tlls ths grave! IS thrown and a small quantity Of water constantly fall ing from a trough above washes 1t over toward tue head onto 0 wire screen which separates all coarse substances and throws them oif. while the fine par ilclss pass through on the face of tbe aulaigam plate, gradually working down. wart, leaving all the free gold with the GEalZEm and concentrating all other metals Et the rilles below.
 Tle cam is operated by a crank and gives iou- vibrations to each revolution of tue shaft. 4 spring throws tue bed sharply back to its place when the cam TtlyGses IL. with a tendency to send the grave! slightly backwards toward the hcnd ot the mecbine, gIvIng plenty of for all particles of gold to come in contac. with the plates.
 The concentrations, m addition to the usual quantity of black sand, contain c nsilsratle quantities ot s.ed gold that will not amalgamate, platinum, silver, bismuth and several other valua- blc metals. The .bl6ck sand IS removed by a simpl process from these metals, and they are shipped in quantities to England for reduction, where they bring from SJ,OO0 to Sl0.O00 per ton according to the proportion of the valuable metals 
 The machine uses very small Quan- .iiy of water. one barrel being sufficient for about sn hour. The water can be saved and used as often as desired, after being allowed 10 settle.
 tu the placer mines where Mir. San iers intends tO operate, the gravel is found at r. n eight inches to two, and sometimes three, feet, all of it contain ing more o= less gold, It pays from Sl 70 to Sj per ton, and the new ma chine will work from fifteen to twenty tons ID ten hours. It IS intended to use a Lcse to bring the necessary water from a spring above the mines, and the machine VI, be moved around to sc- the diggIngs, SO that the gravel will be thrown at one movement directly into the machine. It IS light, and two men can carry 1t anywhere, and it IS also easily worked.
 In point oi expense, the machines can be manufactured at cost of about S6O, which IS exceedingly cheap compared to their merits.
 For this country, where good placer mines exist snd water Is scarce, this is just the thing required. Dry washers are ImpracticBhle with the char ac;er of gravel met with. and this one 1ses suoi a small quantity of water that it will even pay Co haul it long distance or even 10 dig wells and pump a supply.
