FLARES MINE GETS
 A VIVID DESCRIPTION
(Continued From Page N.ne.)

 hundreds of feet fin extent are han dled, with not stick of timber in sight.
 The plan as nearly as can be de- scribed in the absence of a diagram
 is this. A stope, 100 feet wide is
 worked the same distance in length, the ore being broken. occupies great
 CT space than the ore in place, con
 sequently. the miner can stand on the ore and work, and the surplus
 ore is drawn of. The ground will
 sustain itself 100 feet square. When
 this block has been brought to the
 surface or as nearly as the ore con
 tinues, it is "gobbed" in from the
 SUI face, and another 100 foot section
 is worked out. in a similar manper,

 on three sides and the sob on the fourth. When this operation has con- tinued for several hundred feet, or | entirely across the ore body. the operation is carried 100 feet further
 ovsr, leaving a pillar, or rather a wall | also 100 feet in thickness. Thus
 the ore is worked out in rows with a
 continuous pillar of 100 feet between them. Now. do not conclude Tor a
 moment that those pillars or walls
 are to be lost or that any one will be caught while working them out.
 When the stoping is complete, the empty stopes are gobbed solidly. Then the miner drifts entirely under the pillar or wall and begins to stope it in sections of 100 feet The firsI section is sustained by the ends of the pillar or wall on two sides and the "gob" on the other two, and the section is stopped completely. Then they move forward on this pillar 100 Further, after gobbing in the section just stoped out. aud proceed to stope that section, with the original pillar sustaining them on one side and the gob sustaining them on the other three sides, and thus the work is carried on without the necessity of a stick of timber or the sacrifice or a pound of ore.
 Some time ago a mighty cave oc- cured from the surface to the 400 tAs result of not leaving their pil lars diametrically over each other, but it was expected, George Kingdom even predicted that it would come at 10 D. m a certain day, but it cama at 1 D. m. the morning designated. with the only incident on the side that dinky engine was carried down iuoo the mighty crater, and it would be superfuous to add that it is there yet.
 This incident would be one highly interesting to science could elaborate observations have been taken and re- corded. The rusa of air from the stopes when the great mass of earth went in, represented inconceivable power and the dust mounted the sky for miles, imparting the impression to distant observers that an active 1 volcano had put in it's appearance 1 in the vicinity of the Pilares.
 The result of this cave was in no | sense disastrous, though the great | crater is still 10O feet deep and per | haps twice that in diameter.
 The stoping is all done by singIS | jack work, and such is the character | of the ore that tons are broken down | at a single shot, great masses DeIng l brought to the floor which it requires | one or more pops" to break up sui fciently small to yield to the hammer.
 A flash light Of one of the great | stopes in the Pilares would be rev elation to thousands of men who have spent the greater part of their lives | in small or wet mines, where half the | labor and half the expenses arises from the necessity of timbering.
 The Martinez stope was of par ticular interest, where in great | chamber about the size of the Cop l per Queen store, more than forty | men were pounding the steel, the l click Of their single jacks coming like | the tick of a fast watch, the men | stripped to the waist, working tin | wonderful order in good air and surrounded by the best of under ground conditions.
 The miners are all Mexicans, and do good work, an American foreman usually pointing the holes and an other measuring up, the men being paid by the inch.
 The writer desires to here ac- knowledge his obligations to Assist ant Superintendent Williams, Mine Superintendent Smith, and especially to Foreman William Borden, who of fered him every Facility for taking observations in the wonderful prop erty.
 Any one directly interested in the great industry of mining and especial ly in copper can afford when in Doug las to go to Nacozari and visit the great Pilares mine. ALLEY.
