Francis E. Agnew of Oatman is the inventor of a new smelting process that holds out great possibilities to- ward reviving the mining industry throughout immense areas now idle, revolutionizing the industry of the West and the whole world. It is process to smelt dry ores without fux- ing, doing away with searching for wet ores, the expense of paying freight on them and the various big items of cost that have kept many millions of tons of dry ores off the market in the past.
 March ', this year, MT. Agnew was granted a patent on his process. He invented it a couple or three years ago, but for many months had to carry on a battle before the patent office to win out over a couple of pir- ates who tried to steal it away from him.
 Having it now secure ne is ready for business, but he is not offering stock for sale, has no company and in no sense is he trying to finance or float the patent. He has determined to merely let the building and use of the smelters out on a license basis, he acting as supervisor of their building tractive consideration in favor of Mir. Agnew's invention. He states that oH1-r,a,.- of +la -,,,a1+ar oo,, ox-E,.,oE +l,o values at a cost of S1.50 a ton, but that for custom work they can easily get S7 a ton. Either one will appeal personally to those who need smelters to reduce their own ores as well as to those who wish to engage in the busi- ness for others for pay.
 One point that he makes that is all in his favor, is that the patent is pure ly basic. Without copying the prin- ciple itself that is covered by the patent there can be no adaptation nor infringement.
 The surprise of the process is its simplicity. That some one did not and as consulting engineer. In the latter capacity problems that may come up from time to time, with ores refusing to yield to the treatment, his part of the work will be to point out the difficulty and get the values out of the ores.
 For a starter one of the smelters is soon to be built at Parker, which is 65 miles down the Colorado river from Needles. Parker is in the heart of an immense mineral belt where the ores are dry. It has both copper and lead carbonates in abundance and dry ores of gold and silver also are present. It is a typical district that has been tied up for a generation because of there being no fiuxes in reasonable distance.
 Parker is only one out of hundreds of such districts from British Colum- bia into Mexico. In fact, all that ever made the mining camp of Rossland, British Columbia, was the fact that it had fuxing ores and the mine and shelter owners of Montanta were willing to pay the freight on them and treat them free to get the values out of their own ores. Eventually smell NClS NCLE DulAL GlOoG NO 1NOSolellAls anu the Montana dry ores were shipped to them in order to get in touch with the Rossland wet ores. The same applied to the Couer d'Alenes, another wet ore camp that was placed on the map in the identical manner.
 The cost of smelting as another at happen to drop onto it 50 years ago is almost marvellous of itself. It con sists simply of raising the heat in an ordinary furnace to 1900 or 1900 de- grees Fahrenheit, then shooting in heavy charge of crude oil. By being held in a vacuum this does the work and takes the place of all the former troubles in finding wet ores to smelt along with the dry ores.
 The rock is first put through a griz- zly which crushes it down to a half inch mesh. Then it is put through a cement kiln on an incline, which is lined with fire brick. A crude oil blast
