raised in a bucket and dumped into car, which by gravity. ran to the miiI where with one handling 1t passed through the stamps and on to the oelts to come through the wash as copper concentrates. The shaft is now down xo the 200 foot level from which there is a drift to connect with another shaft. the opening of which appears on the other side of the gulch. Every fifty feet cross cuts are being start ed in both directions. Drifts and cross cuts will be run in all directions and eventually they will all be connected and the mountain will stand support ed only by labyrinth of pillars.
 Very recently the bucket has been supplanted by a cage and the original plans for a double compartment shalt have become a reality. About 1000 feet of work has been done and every tone of material removed has been of a character worth putting through the mill.
 The stamp mill has a capacity of 90 tons a day; plans for increasing the capacity three-fold have been approv- ed by the financial board. It is ex- pected that work on the enlargement will begin inside of two or three weeks. Machinery for lighting the mip by electricity is now on the way.
 The milling plant of the Kelvin Re duction Company is operated under the same management. although not a part of the property. The plant is a little farther up the main canyon and directly across from the town of Ray.
 In both mills fuel oil is used in de veloping power.
 To the east of the Big Lead prop erty lies the Calumet mine. The work here has been principally tunnels and has been very profitable. The ore, as mined. has been shipped to the smelter at Fl Paso. The lower workings are in sulphides.
 Very recently the interests of the Calumet and Big Lead were, joined in a new company. which will work both properties MT. Twitchell win remain as superintendent. The new organiza- ,tion is styled the Kelvin Calumet Cop per Mining Company. and at present is employing about seventy-five men,
 Adjoining these mines and lying on the east side of Ray is the property of the Arizona Hercules Copper Com pany. It embraces fifteen claims and at the present time employees a force of about fifteen men, while like number are employed on the Sidney group of twenty claims.
 $ Both properties are being developed under the direct superintendence of F. G. Thomas. It is the intention
 
 when cool weather comes.
 Within the past week deal has been consummated whereby additional capital has been interested in the. Bob Tail Junior group of six claims
 The claims are bounded by the Ray and Arizona Hercules properties. About seven hundred feet of devel- opment work done has shown ore with copper. gold and silver values. It is understood to be the intention of the owners to push the development work.
 Across the river from Kelvin is the Sultana- Arizona property. It em- braces about three hundred acres. Just now ten men are working under the superintendency of MT. J. T. Harring ton. MT. Harrington states that it is the purpose of the Chicago company that owns these claims to make the development work pay for the equip ment necessary. Selected ore is being shipped to the smelters at Douglas and Fl Paso. Mir. Harrington estimates that between forty and fifty thousand dollars worth of two per cent ore is on their dumps witing for the building of a concentrator.
 He states that although the develop ment work is only partially done so far twelve or thirteen ledges have been found.
 Owners of groups of claims that have not vet reached the stage of pub lie attention are active and any day may bring one or more of these groups to the front.
 Included in the Kelvin district are the mines at and around Troy. Coch- ran, Christmas, Winkleman. Superior
