58 The Mining and Scientitic Press iat Important Success. Those of onr readers who were with us some eight months since, will recollect that we gave a detailed account of the successful working of a new process for treating gold ores-—particularly those largely charged with sulphurets—which lad just been intro duced into the Pikes Peak mines. This process was known as the “Keiths Desulphnrizing Process.” Soon afterward we understood the process did not promise so well, but tbat further experiments were to he made, which it was confidently predicted would result in a more unqualified success. We have watched with much interest for further developments, which have at leugth come to hand in the Colorado Mining Register of December 31st, from which we extract as follows : Our miniug men have long looked with anxiety upon every new method of treating ores introduced here. The fact that we have been able to obtain not more than twenty-five per cent. of the gold contained in them, and that it has frequently been much less, had induced the hope aud belief that some method should be discovered wherehy better results micht be obtained. The results obtained a year ago by Dr. Keith, by means of desulphurization and calcination, gave rise to the expectation that his method would succeed. Imperfections, however, in the machinery and apparatus employed, gave a serions check to the anticipations of those not directly interested in the experiments which were being made. Nothing daunted by the apparent failure, Mr. Keith returmed to New York, and formed a powerful company there under the name of Keith, Mohl-r & Co. 'They bronght bere last summer the fiuest engine in the Territory and with it several modificd Howell crushers and other machinery. ‘They have uow got itin workiug order, and last sveek made their first tun. They erushed one cord (14,700 pounds by actual: weight) of secoud quality ores from the Gregory Lode, such as have hitberto yielded ouly $100 per cord by the usual method. ‘his, after being desulphurized and calcined, weighed only 8,871 pounds, or but little more than one-half the original amount, ihe waste, composed of sulphur and other volatile substances, haying passed off in vapor. The ores, after being thus treated, were rnn through a Frieburg pan for amalgamation, and yielded thirtysix ounces of superior retort, worth $864 in curency. This, as will be seen, is nearly nine times the amount formerly obtained. We give this statement of the result of this run, and of the quality of ores, as reported to us by Dr. B. Keith. in whose statements we have the fullest confidence. Previous experiments have given similar results, and afford increased proof of the utility of the process. The result is a very flattering one to the people of Colorado, as the practicability of this method is now fully demonstrated. From eighty to ninety per cent. of the gold can by this method he constantly saved from the ores. Jt also enables our people to work successfully a class of ores well known to be rich, but from which we have hitherto failed to separate the gold on account of the presence of arsenic, antimony aud other metals and substances which are readily volatilized. It will be noticed that the above is but the result of a first trial, with the new ‘macbivery. We shall look with much interest for further developments. Should they continue favorable we sball agaiu lay before our readers a full detail of the process, together with such improvements, so far as we can obtain them, as have recently been made. Trrriric Locomorive Exprosion.—A terrific locomotive boiler explosion recently oceurred on the Cen-. tral Railroad, in, New York, while the train was under headway. The boiler itself was thrown 825 feet into an adjoining field. The balance of the locomotive was thrown in every direction. ‘A Minino Stock Boarn has recently been established at Victoria. Transactions’ will hereafter be regularly quoted. The fact is tmportant as showing the permaneucy of the mines in that region, and that capitalists are inclined to encourage tbeir development. Mam via Henness Pass.—At the instance of Senator Conness bids will be asked inthe next schedule for carrying the mails between Nevada Territory und California over the Henness Pass route, Mining ‘Laws~-A Good Suggestion. The Calaveras Chronicle makes the following excellent suggestion with regard to collecting the local mining laws of the State for préservation and convenient refereuce. It is certainly a most important and very proper matter for legislative action : “here should be some method devised by which the Mining Laws of the different districts could beso consolidated and arranged that in each county, at least, there would be a written code, whiclt should be published and preserved in the Recorder's office. At present every mining district has its rules and regulations, and it is ofteu impossible for parties to find out the laws of any particularcamp. The Courts respect the laws of each district, but as there has been no provision made for pnblishing them, they are liable to be lost or destroyed, thus subjecting parties litigant to much trouble and expense. We now have the advantage of along experience in mining, and know the wants of the ininers, aud it would not require much time for a body ot delegates, elected from the mining districts, to frame such laws as are needed within the boundaries of a couuty. Gold, silver and copper interests could be arranged under appropriate sections, so that there would be no conflict between the several kinds of mining. The advantages of such a system are apparent to all; andif the Legislature would pass an Act authorizing such conventions, and make their laws valid, we believe all of the mining couuties would adopt the proposition. The tendency would be to lessen litigation, as much of it is now caused hy parties trespassing upon the rights of others through ignorance of the miuing laws of the district. Gross CareLrssnrss.—It appears by the full accounts which have now come to haud, detailing the loss of the iron-clad Weehawken, that she went down through sheer carelessness on the part of her officers and crew, some thirty of whom found a watery grave with her. Her commander was absent at the time, aboard of the flug-ship, in consultation with the Admiral. The ship lay very low in the water, and it appears that the forward hatch was carelessly left off, into which the water rushed, in a continuous stream, as soon as the gale hecaine sufliciently furious to raise a very heavy swell. ‘The officers in charge were not aware of their danger until it was too late to save the ship—a panic having scized the crew as soon as the alarm was given. . : Mechanics’ Institute Lectures.
