I I'UM'I T1!E CAIIPETS. THURSDAY, NOVEMBER 30, I 893. A ! Hot Hlant Air Furaaee. Olobc Sllrer Rett. An Improvement recently placed on the water Jacket furnaces of The Old Dominion Copper Co. at Globe, con sistsof an arrangement for heatingthe blast before It enters the furnace, and as it has been so eminently successful in Its work it will be here described in detail, first giving the construction and afterward showing what effect it has had on the working of the furnaces and in what ways has it accomplished a saving in time and a reduction in running expenses, The improvement is of the simplest kind, consisting of a wind jacket com pletely, surrounding the crucible of the furnace, and being in connection with the blast supply pipe and also with the regular wind box. In opera tion the blast coming from the supply pipe enters the wind jacket in the usual cool condition, slightly higher than the surrounding atmosphere, and passes completely around the crucible. here coming in contact throughout it passage with the hottest portion of the furnace. After making the cir cult of the crucible it tlows into the regular wind box, thence to the tuyere: in the regular fashion. In making this passage it serves sev eral purposes: 1st. It heats the blast to a high de gree by taking up the heat which ha; formerly been lost to such a large ex tent by radiation, now taking it back into the furnace to perform useful work by reducing coke consumption. 2d. It keeps the crucible from get ting abnormally hot, thereby saving wear and tear cuned by great varia tions of temperature, and saving the timn wliii-h was formerly lost in-cooling it down when -it' got ia this highly lu ated condition. M. Making it very much cooler and more comfortable for those working in the vicinity of the furnace. When one of these new w ind jackets was first placed in operation a compar ative test was run with a furnac pre cisely similar without the wind jacket, both being 42-inch furnaces of the or dinary type. The test was very suc cessful and 'showed that the jacket effected a saving of five pounds of coke in every charge of 800 pounds of ore. In this furnace the temeratureof the blast was raised fifty-five degrees, as determined by many readings taken J ust before entering and leaving the jacket. Shortly afterward a wind jncket v. a placed around the eni.-ible of a .pchk.' furnace, aud by slightly modifying tin design It was made even more success ful than the first, as in this case the temperature of the blast wa; raised M.5 degrees in passing through the jacket, and the furnace is now running with one pound less coke per charge than the first, or six pounds less with the Jacket than without. As stated above there is increased economy by saving the time which was formerly lost cooling dow n tli" cni'-ible when-j ever 11 oecamf! aMit.r'o:!'!'.- ),',, !ir. ir-i by a'.IouiiTK vr--c :. to be -ro'-'ti-.f ;U 1 tiie same cost for labor and fixed charges.

The purity of gold is estimated by an Abyssinian weight called a carat Arabian quarat. abeanajfruit of the carob tree, says an authority which is subdivided into four parts called grains, ine'terni carat when applied to gold and silver is not a weight unit, but that mode- of expressing the parity or fineness of the metal in24ths. Thus I S carat gold is metal in which eighteen parts out of twenty-four (or three-fourths) are pure gold. This method of estimating fineness is trace able, from the marc of Europe having been divided into twenty-four real- carats or actual weight units.. The present method is to estimate fineness in thousands, that is gold that has 250 parts alloy corresponds to IS carat gold, three-fourths of the metal in each case being pure gold. American gold coins are 21.19 carats. Ores and Metals. Monday of last week Mr. Sullivan of Willcox, took into town a huge wild cat he had captured.
