Inner Secrets of Early Foil Which Brought Great Things, Together With Sci entific Data

A history of early day mining in
 the Warren District, when the
 Copper Queen company first en-
 tered the field and began to make
 history, doubtless will prove eX-
 tremely interesting to the people of Bisbee, particularly since the writer, he who had most to do
 with making the name of Bisbee
 signify supremacy in the world of copper mining, passed away
 early last week in New York.
 The following extracts from a paper presented to the Institute of Mining and Metallurgy in London, England, by Dr. James Douglas, tells in an inter- esting and effective manner the story as none other was or could be pre- pared to tell it:
 But, notwithstanding its subsequent prominence, the Warren district had not attracted as much notice as some other districts before its active devel- opment. One reason was that the experiencing limestones which dip south from the core of the Mule Pass mountains exhibit very few exposures of ore It is now known that the whole series of limestone, extending from the Cambrian to the upper Carbon iferous, all carry some copper, but the beds which contained, so far as eX- posed, the largest masses of pyrites under conditions favorable for the decay, and during which copper was concentrated as oxidized and second ary sulphide ores, are found in the Carboniferous and to a lesser extent in the upper Devonian limestones. As these are overlaid by hundreds of feet of comparatively barren rock, and as the beds which contain the ore bodies dip more steeply tc the south than the inclination of the surface, the surface ore bodies in these productive lime stones were exposed only near the outcrop of their beds, and the deeper ore bodies of the chain had to be sought for at steadily greater depths.
 The enc notable ore body which made the district famous cropped out in the Copper Queen claim, on the northern exposure of what was sub sequently known as the Copper Queen hill It was an almost circular body of oxidized copper, iron and mangan- csc, Approximately sixty feet in diam eter, enclosed in unaltered limestone. The ore was so basic that for short time foreign silica had to be added to the furnace charge, but it was so rich that for months the furnace yield was g per cent of copper
 The furnace plant consisted of one water jacket of 36-inch diameter, sup 11a af rl l,,- They were erected immediately be- meath the open cut from which the ore was shot down, through a breaker shed, on its way to the surface.
 There was at the time only one other company extracting a small quantity of surface ore from the Neptune group of claims, to the south of the Queen hill. The profitable deposits lay so far below their surface that even the most enthusiastic miner would have lost courage in looking for them. The property of this company, consisting of seven claims, was ultimately sold by the sheriff. and passed into the possession of the Copper Queen Min ing company. These ore bodies reached by underground development on the dip of the limestone-are still providing the Copper Queen company with fair share of its ore supply.
 In the beginning of 1891, though active mining was being prosecuted only on the Copper Queen and Nep- tune claims. the district for a long distance round had been located I'm mediately above the Copper Queen, on the hillside, a parallel claim, the At
