SIMPLIFYING FURNACES.
Revelation m the Smelling Busi
 ness Of the Country.

 both galena and copper ores, built by Msssrs. Rankin Brayton & Co.,, of the Pacific Iron Works, San Francisco. have worked a revOlu. 1 ton in the smelling business of the country.
 Tn, adv Intages demonstrated in these furnaces are facility and cheapness of transportation and construction, economy O. fuel, Hneness Of bullion produced aud capacity for continuous and unin- terrupted work. Any ore tha, can be smelted, it is claimed, can be worked cheaper in these fur naces than by any other process.
 The mining interests of the country are largely indebted tu this firm for working up to such g state of perfection this impor> tant branch ofminIng machinery. A large number of companies in Arizona, Idaho, New Mexico and Nevada are operating these fur naces with most satisfactory re suits. The manufacturers report orders recently received for three forty.tOn smelters. to be erected in the Wood river country this spring. Below will be found a statement from the Superlntend- ent Of the well-kuown Castle Dome Smelling Works, in refer ence to the operation of these smeIters, which would seem 10 be conclusive as to their merit and superiority.

 SIMPLIFYING WORKS, MELRosE, CAL, Feb. 13, 1882.
 GENTLEMEN: MEssRs. RAN KIN, BRAYTON & Co.,, "Pacifir Iron Works" San Francisco, Cal: In reply to your application for & statement of the working of our furnaces, would say that we have two of your 40 ton galena smelters in our works, that have been running most of the time for last two Years. With ordinary care I have nu difficulty in keep ing them in condition for constant service. The patent circulating plates, recently introduced into AUur water jackets, I regard as the nust important Improvement ever made in Water Jacket Fur naces and worth mpre than au entire cost ol an ordinary jacket. There Is no Question but tn u d jacket for either gtlena or c.I'per ores, with this Improvements, w.n last two or three times as much aS without il, besides leaseuing the liability to imjure and the con. sequept expense aud loss of time fur repairs. Since the adoption of this improvement, 1 have had no trouble whatever with my
 tckets. The circulation of me Water is 50 rapid that the inner surfaces of the plates are kep: secured and entirely free from any incrustatiUn, and seems to of 'rd perfect prutectien from the l effects of miiieraliZ d water, and frum the Over-heating and burn ing out SD common III ali other jackets. Your style of sectional water jacket has many and obvious advantages over all other forms. The distribution of the blast and the angle of the tuyer, are such as are calculated to se- cure perfect combustion and tle greatest ecOuOmy in fuel.
 With a long and varied exper- ieuce in smelting ores from wide range of mineral country, I unhesitatingIy give your furnaces the preference over any I have ever seen. The machinery cons prl'ing the smelling plants fur. nished by your firm I regard as admirably suited 10 that purpose complete in detail and d.pted to all the requirments of practical work. The improvements you have made in this class of machinery are recognized as of great value to the mining inter. ests of the country, and makes smelting, under ordinary condi- tinns, the cheapest form of reduc-
