Smelling Furnaces.

The water jacket furnaces, for both galena and copper ores, built by Messrs. Rankin, Brayton & Co.,, of the Pacific Iron Works, San Francisco, have worked revolution in the smelting bushes of this country The advantages demonstrated in these furnaces are facility and cheap ness of transportation and construction, economy of fuel, fneness of bullion pro- duced and capacity for continuous and uninterrupted work. Any ore that can be smelted, it is claimed, can be worked cheaper in these furnaces than by any other process. The mining interests of the country are largely indebted to the enterprise of this firm for working up to such state of perfection this important branch of mining machinery. A large number of companies in Idaho, Arizona, New Mexico and Nevada are operating these furnaces with most satisfactory re- sults The manufacturers report orders recently received for three of their Acton smelters to be erected in the Wood River country this coming spring, and also a large number of others for different parts of the coast Below will be found a state ment from the superintendent of the well known Castle Dome Smelling Works in reference to the operation of these smelters which would seem to be conclusive as to their great merit and superiority:

 GENTLEMEN:-In reply to your applica- tion for statement of the working of our furnaces, would say that we have two oi your 40-ton Galena Shelters in our work, that have been running most of the time for the past two years. With ordinary care have no difficulty in keeping them ill condition for constant service. The patent circulating plates, recently intro duced into your water jackets, I regard al the most important improvement evel made in water jacket furnaces and wortf more than the entire cost of an ordinary jacket
 There is no question but that jacket fol either galena or copper ores, with thi improvement, will last two or three time as long as without it, besides lessening tn, liability to injury and the consequent ex pense and loss of time for repairs. Sine, l GHe duOpGlOll Ol IlllS improvement l udN' had no trouble whatever with my jackets The circulation of the water is so rapic that the inner surfaces of the plates ar kept secured and entirely free from an, incrustation, and 1t seems to afford perfec protection from the effects of nineralize, water, and from the over-heating an, burning out so common in all other jackets Your style of sectional water-jackets ha many and obvious advantages over al other forms. The distribution of the bias and the angle of the tuyeres are such a are calculated to secure perfect combustion and the greatest economy of fuel.
 With long and varied experience i smelling ores from wide range of miners country, I unhesitatingly give your fuI naces the preference over any have eve seen. The machinery comprising tn smelting plants furnished by your firm
 regard as admirably suited to the purpos complete in detail and adapted to a the requirements of practical work. Tn improvements you have made in this clas of machinery are recognized as of gres value to the mining interests of the cour try, and makes smelting, under ordinar conditions, the cheapest form of reductio for any ores that can be worked by tn process. Yours truly,
 w P. Miller, Superintendent.
