pounds, was brought to town yesterday morning to show Mir. NewhouSe. He had been waiting on that demonstra- tion for several days. As soon as he saw the bui ion and knew that success had crowned his own and the inven- tors efforts, he packed his grip and left for New York, about the happiest man that ever boarded train for the east.
 When Mir. Fink had the furnace con- structed for the trials that have been in progress it was designed to burn oil instead of pulverized coal for fuel. When he arrived here it was found that it was going to be difficult 10 get fuel oil delivered and so he was asked to change the burners and blasts to utilize coal. Now that he has made the tests with coal for fuel, he will immediately change and substitute oil, which is now available. He declares that it makes no difference with the work of the furnace whether coal, oil or even charcoal is used for fuel. It will operate equally well on either. There is no use to talk about coke for fuel, he says, as that is too expensive and not at all necessary. Where sul- phide ores, such as those he has been conducting tests on. are used, the sul- phur supplies practically all of the heat units necessary, without the ad- dition of fuel. Oxide and carbonate ores, both copper and lead, will yield 70 treatment most readily when prop erly lluxed, and an exceedingly small amount of fuel will be required. The size of the furnace can be adjusted Jl any character of work, and Mir. Fink expects to handle zinc ores with per feet success. The furnaces in use at the Garfield testing plant are nine feet long and nine feet in diameter. For some classes of ores it will likely be possible to make them larger: with others it may be necessary to reduce the size. For plants of limited capac- ity small furnaces will be built and in all cases it will be case of making the punishment fit the crime"
 Now the world must sit up and take notice. There can be no more charg- ing of exorbitant prices for the treat ment of ore. The man with material that carries los ton in value can erect a small shelter at a nominal cost and treat his ore at a convenient spot and ship his bullion. In this way he can do for a matter of a dollar or two a ton which now costs him so much that it is impossible to move his product at all. He can take the smell ter anywhere, almost, and he can drill men to run it in short order for the mixing of the ores Is the only thing that will require metallurgical talent. The simplest kind of machinery will supply the necessary power, and the results will be certain. all the time. The shelter can be shut down and started again at will, as there are no ''freezing up'' difficulties to contend with. Owing to the cutting off of power the testing plant at Garfield has been ''frozen up" a dozen times dur ing the past couple of weeks. It has been ''thawed" in an hour without the laast trouhia Op damaUa and the amount of heat generated has been controlled just as easily as it is to turn the water on or off at bathtub faucet. When it is known that it costs often as much as 5S or 6S to dig out frozen charge in blast furnace of the ordi- nary kind, the importance of this fea- ture of the process becomes readily apparent.-Salt Lake Herald.
