dollar. This came from test made on seven pounds of Mover ere which assayed 12-100 of an ounce in gold This would give $40 to the ton Els timating the gold from the seven pounds at 60 cents, would mean that Mir. Neubarth's method would yield S171.
 "A few days ago a prospectOr brought in a sample of ore that showed ac- cording to fire. assay a trace of gold The ore. about a pound of it, yielded gold in sufficient quantity to show $6C to the ton.
 "The question was asked whether the product of the tests was really gold MT. Neubarth says that he made tests and others had taken the stuff to as- savers, and it was pronounced the gen uine article.
 "The process itself is naturally Mir Neuba-th's secret. He has the formula of course, carefully preserved, with complete record of every experiment, so that there will be 10 danger of the secret being lost in case of accident. The experimental tests are very sim pie, for he has no elaborate apparatus. The ore is reduced to a fineness suffi- cient to pass through a 40 mesh screen. It is then mixed with the chemicals and water and subjected to agitation for from fifteen minutes to an hour, the time depending on the character of the ore. After that it is allowed to settle, and the gold. MT. Neubarth ex- plained, is held in solution in the liquid. This liquid is then subjected to the action of chemicals. and in the course of tweney-four hours fine par ticles of gold are seen floating on the surface of the clear liquid. These are taken off and when dried present the appearance Of an impalpable brown powder. which can be reduced to d me- tallic state by heating in a crucible Mr Ncubarth displayed several ordinary glass tumblers in the bottom of which was a bluish sediment, filled apparently with water, on the top of which minute particles of gold were floating. The gold resembles the product obtained by Professor Wynn. The fact is that if there is anything in that process, and Mir. Neu5al th is inclined u believe there is, he has antedated the Wynn dicccv- cry by five years.
 "Mr. Neubarth does not discrcdit the Ire assay 1Ur gold at all. Tor the sim pie reason that by this method the as saver can determine how much metallic gold there is in 9 given ore. The oil of gold as he calls it, is not gold. as it is generally understood. out vola- tile substance that simply passes off IT. fumes when detected to heat Conse- queEtly 1t cannot be subjected to fire test. An ore containing metallic gold in commercial quantities does not yield any quantity of additional gold when subjected to MT. Neubarth's process. It has. he points out, reached that stage Of development where the immature gold has all been precipitated. T can take the pulp after extracting the gold from it by my method, ne stated, and it will give exactly the same result by fire assay as before. The assayers are net at fault in the matter, because the gold which I obtain is not gold in the crude ore
 MT. Neubarth is not speculating on the future. He may make some tests on a large scale later. and figures that the ore can be treated on a commercial basis of 8 or $1O a ton, which is much cheaper than the Wynn method. In fact the latter process required expensive chemical Is. Mir Neuharth does not use high-priced material
