 Globe Silver Belt.)
 Through the courtesy of Dr. Alex Trippel, superintendent of the Old Do- miDinn Copper Mining Company, We were shown through the companys mine, the Old Globe, on "Wednesday. Since cur last visit. year ago, an lln- mense amount of ore has been extracted and a great deal of development work done, which has changed the appearance of the underground workings to such nn extent that We scarcely recognized It as the same mine. Under the escort ot Eugene Trippel and. Foreman Andrew Scott. We made a complete circuit ol the mine, except section or the old workings.
 Some oi the most important work Of the past year noted was developments in the northeastern and southwestern parts of the mine. Ih the northeast, on the second level. developments have been pushed in the Globe Ledge claim, 250 feet from the BIT shaft, the point or intersection between the Globe and Globe Ledge claim. In southwest ern direction they have gone 6OO feet through ore, from the second to the fifth level. Other important develop ment work has been done between the Moony and Saunders shafts where, on the fourth level, the greatest ore body, encountered since our last visit, Was opened. while the ground between the same shafts (which are 40O feet apart ) and between the first snd fourth levels, has not yet been developed. These areas have recently been penetrated by a wlnze and drifts for the pdrpOse of exploration. AIthe present time, on two levels, there are connections made be tween the southwestern and northwest ern. extremities, fully l6O0 feet apart. Important discoveries were made ID an unworked part of the second level, which 1 is now producing most of the ore that | istsmelted. The ores are sulphurets, eX ceedingly rich, some assaying us high as 80 per cent, which in smelling pro- duce large quantities of rich matte, be sides the pig copper, During the past three months work m the mine bRs been prosecuted with more than ordinary vigor. Pumping machinery has been | introduced; connections between the Moony and Saunders shafts, on two | levels. are almost completed; the Moony shaft will soon be sunk to the filth leve and the latter pushed ahead several hun | dred feet.
 On the fifth level they are now run ming parallel with the foot wall. II close proximity to what is undoubtedly an immense ore body. The diorIte | .. na-a1 au afsaf with considerable quantities of natIv, copper, some sections containing s' much ss nine per cent, which Ike tht | Lake Superior ore, can be secured oy washing. The largest ore-body m s'gh IS on the fourth level IL IS high grade ore, averaging probably seventeen pei cent or more, but, owing to wat, n th' lower stVpe, 1t IS nOtibelng worh d. Al soon as the drift on the fifth level reach es a point beneath the fourth leye stopes, connection will be made and tho water drained of. The water in th' mine Is of little consequence and tn, capacity of the new Knowles pump Il sufficient to easily keep the lower leveli dry.
 It has teen proved beyond e doub that the Globe vein Is n contact veIn having for the footfsll igneous (erup- tive) diorite and as hanging walls sedl- mentary rocks; in the upper levels, pro bsbly, silu:isn limestones m met8mor phic condition, as qusrtzites. An ex- pert, in s recently published essay oI the copper mines of the Southwest, says "the Globe mine has been, perhaps, tn, most regular of all the veins described, | The ore-bodIes as seen now have theii origin on that contract, and although branching out largely, far into the hang | ing rock, can be followed down to tht fifth level, and all along the footwall This fact IS or great importance. Many apparently disconnected ore bodies ar, found iu limestone or quarizIte. but it is probably true that the best copper mines in this section have a similar con struction, geologicaily speaking, ss th, | Old Globe mIne.
 The Old Globe has been, Up to tho present time, one of the few copper mines that can be called seli-susiaining | All the improvements were paId fol from its earnings, with scarcely anN working capital 10 back IL up. With the prevailing low price of copper, tho Old Globe is the only copper mine II the south west that can be worked with out loss, and with the completion of 6 railroad to this tOwn-the prospect fol winch is encourRging-there IS littlt doubt but that the Old Globe can com pete successfully with the Calumet < Hecls mine, on account of the excellent character and richness of its ores. The output of the Old Dominion smelter is almost uuequalled, considering its co pscity, and especially Of late, some ter or eleven tons of fine copper are pro duced daily by one 30-ton furnace. Il is confidently expected that the best run ever made by the company with one furnace will be recorded this month probably 80 toDs-provided coke con tinues to arrive uninterruptedly.
 The present splendid showing Is cred itable to Dr. Tnppel, the superinteud, ent, who has conducted the Company's business here with economy rni success with many annoying circumstances tC contend with. Others Tn charge of de- | partments, notably the smelter and | mine, are deserving of high praise foi the ability shown by them. The genera results must be very satisfactory 10 tho owners of the Old Globe, as everything consistent with good work and economy IS being done to combat the present de precision in the copper market.
