The tots-l co.st for labor per ton amouuts to twenlv five cents, and the entire cost of treating a ton of ore by this process is about W.35. In a mill especially adapted to it the cost would bo about $1.75. There are three mills of this kind working successfully in Old Mexico, one in the Wue Bird at Butte City, one in Washington and one on the Saratoga mine near Ouray, Col., and one building in Australia. There is no secret in connection with the Russell method of lixiviation, but the combination of chemicals used tiro patented. The credit for discovering this truly wonderful process for the extraction of the precious metals from tho worthless having givcu the world something of value. . ... I was informed by Mr. Ku.ssel the inventor, that he hud received and treated in the works here, ore from Colorado, Montana, Central America and Australia and had never failed to get satisfactory results out of any of them. In addition to these tests, there are mills using this process, in successful operation in Old Mexico, Washington and many other places. In no instance has ore been found that could not be successfully treated. While, of course, the lead or copper in ore cannot be saved, it does , not interfere inter-fere in the slightest degree with the saving of the gold and silver as the chemicals only act on those metals. The process is now used here at the mountains can compare with with it. Every moment is a new picture jnd every- twist and curve a new delight. It is a constant change from mountain to meadow, from orchard to canyon and park. Ranches that are gardens, seem to hide with maidenly shyness in the valleys, guarded by grim old peaks. They are such spots as a landscape artist, art-ist, might dream of producing, but nature has done it all, while through them a stream of liquid crystal murmurs mur-murs in sweet rythm. The hills on either side are as green as Eriu's banners, ban-ners, which are diamoned in spots with banks of snow. Park City itself is a place of no mean pretensions.

While the description given is doubtless doubt-less very crude and incomplete, in a technical sinse, it is believed that those who are interested in such matters will be able to obtain a general idea of its working. The results obtained from this method of lixiviation are most satisfactory, running from 00 per cent up. While it can be worked as high as U7 per cent it is not thought advisable to do so, be- MAHSAC MILL in the treatment of the milling ore from the Daly mine. This mill is only a stone's throw from the main street of the town, and it has beeu running uninterruptedly since January 1, 188U. The mill is quite an old one, having been built some years ago to treat ore by amalgamation, and as it was not constructed con-structed for the purpose of treating ore by this process, the working cost is necessarily a little more expensive than it otherwise would be...".' The only real difference there is in the Russell lixiviation process from cific having a much finer depot here than at Salt Lake. True, its principal street starts at a break-neck speed for the clouds at an angle of 45 degrees, de-grees, but like all the other thoroughfares thorough-fares in this thrifty place, it is kept clean and well sprinkled. It boasts of a fine hotel, opera house, churches, good public schools, pressure water, fine homes and good society, as well as of its rich mines and general morality. Its people are prosperous, for here is disbursed about $123,000 a month for labor alone and manufactured by I'reseott, Scott & Co., of 200 horse power.

There Is a very good natured rivalry between him and Mr. Russell of the Marsae iu arettintr the best result. cause it would increase the cost of treatment to such an extent as to counteract coun-teract the greater saving of value. One thing that I had almost forgotten to mention in connection with this method of leaching, is that It often saves the gold in ore much closer than by amalgamation. The JJaly ore only runs about $1.50 a ton in gold, yet last year the mill extracted $17,000 from it, or nearly enough to day tho expenses of the leaching department of the mill. The Marsac mill treated last year 28,000 tons ot dry ore from the Daly which yielded 870,000 ounces silver and BOO ounces gold. ONTARIO HILL. amalgamation is after it passes through the stamps. Without going too much into a detailed detail-ed description of the works which uses this method of leaching, it will be necessary to give a general idea in order to be understood at all. As stated before the method does not differ much from amalgamation until the ore reaches the batteries. The process pro-cess is part dry and the rest wet. The ore is lirst dried before going into the batteries which use a little coarser screen and a less per centage of salt than in amalgamation. After being crushed the pulp is hoisted by elevators to Stetcfeldt furnaces, from which it is taken onto the cooling floors. From is not an uncommon occurrence to find a man working in some of the mines or mills at day's wages who is worth from five to thirty thousand dollars dol-lars in stocks in the various properties which he may have acquired years ago when they were not so valuable as now. I have never been iu any camp in the west where there seemed to be more push and energy than here. There are few idle men and no loafers. The crushers and rolls of the five mills and concentrators never - stop night or day, year after year, as they continually produce pro-duce either concentrates, silver bars or Russell process sulphides, which arc liftv per cent silver. Of course theTark's greatest attraction attrac-tion for years lias been the Ontario mine, th3 record of which is known everywhere, and its wonderful pumps and engines are visited by thousands annually. , , . . j But the mine has produced something else of value to humanity other than , silver. It has graduated some of the ABLEST JUNE AND MILL MEN in the country. It was at this mine, under its fostering care and encouragement, encourage-ment, that one of the most wonderful processes for the separation of gold and silver from the worthless rock, had its birth It is wonderful, because it is successful, in extracting the value from the ore at a low cost. Mining camps as a rule breed as many processes as a swamp does miasmas. mias-mas. But there arff processes and processes, pro-cesses, some of tbem cost more to treat a ton of ore than the value it contains, and then will only save a small per centage of the metal.

This mill has just started up after a shut down of eight days, for general repairs to engines and batteries, the first complete cessation of operations in four years. Its capacity is from eighty to eighty-five tons of ore every twenty-four twenty-four nours, and like the Marsac mill which uses the Russell lixiviation lixivia-tion process, this saves about the some per centage of value. I. e., 91 per cent. This, all things considered, is a very satisfactory result. All of the ore for this mill is drawn 'from the Ontario mine about a mile away, by wagon. On arriving at the mill and first being weighed, it is shoveled shov-eled on to the receiving floor which has a capacity of eighteen hundred ton. This enormous bin is kept stored with ore in case any accident should happen at the mine which would curtail shipments, ship-ments, or if the roads should become this floor it is dumped into six sixty-live tou vats. Water is then turned ou to extract the sodium of gait and base metal salts formed in roasting. These solutions are passed through slats iu the false bottoms of the tanks forming a clear liquid. After leaching with water, a portion of the silver salts are removed by turning on a hyposulphide solution, which dissolves a portion of tho compounds. The other silver salts which are not soluble in that solution, are removed by a solution solu-tion of hyposulphite of soda, together with sulphate of copper, to the amount of two and a half pounds to the ton of ore. All solutions . pass through false bottoms in tanks . to precipitating vats, where they are precipitated pre-cipitated by the addition of sodium sulphides, sul-phides, precipitating the silver in solid form, which is permitted to settle to the bottom of vats, when the clear solution is pumped up into storage tanks, to be used again indefinitely. About once a month the sulphides are drawn off from the vats into iron pressure tanks, from which they ore Denver w hich ha made a contract for entire product until next November.
