Mayer, Ariz, June 2.-(Special ccr- respcndence of The Republican.J- One mile west of the Crowned King is the Union mine, formerly and perhaps better known as the Gretna, the prop
 erty of John and Frank Luke, who have put in about a years work on it. A level has been driven AIS feet on the vein and some little cross-cutting has also been done. The Gretna mine dates as far back as 1876. when the surface ores were worked for gold and silver, but not proving to be milling proposition, and there being no means of pioper treatment work was discon- tinued.
 The Union is on the same vein as the Crowned King and little difference exists between the ore lately worked in the King and that taken out in the development work (20O tons are now on the dump) recently done in the Union mine, except that the former carries more lead and the latter more copper.
 Tc the greater extent the ore is a sulphide, the values being carried In what is known as the gray copper. The ore concentrates at about five to one and the concentrates properly treated are said by the owners to be worth $50 per ton, the plating returns being three dollars.
 Iii other quarters I have, however. been informed that this ore is diffi- cult of concentration and that the proper method of treatment is to put it into a smelter. If this is the case the successful carrying out of the pre- jected reduction works at Mayer should make the Union a valuable property. The owners have grAat faith in the mine but are not capi- talists and are prepared to give a working bond or would make any req s0nab;e terms with an investor who is desirous of tempting fortune in the Bradshaws.
 About a mile and a half northwest of the Crowned King is the Gladiator, the property of the Gladiator Gold CCIapd4y O1 OSuN6I. Frank Giroux is superintendent and E. F. Marlow is foreman. This mine has been working under the present ownership for the past five years dur ing which time a tunnel has been driven GEO feet in length cutting the vein where it has a cover of upwards of 600 feet. A shaft from the tunnel !, o1c some five to six thousand feet of development work has been done. The ledge which is a parallel enc to the Crowned King vein runs from three to three and half feet in width between the walls. The ore is a of zinc with considerable iron and little lead but the gold is free and is miiled at ten-stamp mill ,n the mine
 As at the King the ore in the lowest workings of the Gladiator is beginning 10 show more quartz and is getting nore like an ordinary free milling ore. 0n recent test this ore assayed s53 md milled S4S. There are 1000 tons # concentrates at the mine worth dose upon s30 per ton which have not been shipped owing to the heavy reight charges and this and similar ,ccumulations of low grade concen- rates at other mines in the district of CT further encouragement for the es- of the proposed reduction works at Mayer
 The mill is to be remodeled and arge force will probably be put on all most immediately to thoroughly open ID the mine, which is considered to be very valuable one, and will shortly 'e working On a much larger scale han it has hitherto done. There is n abundance of water for milling and a plentiful supply of Tood at s a cord.
 
 About a mile north of Crowned fling is the Watsonville claim, worked " Capito and Ward under bond, who ave driven some 25O feet of drift and re now in good body of ore which 5 said to assay $40 per ton.
 The War Eagle, a parallel ledge to he Gladiator, is being developed by IT, Jenkins, who has done consider ble work upon it and has a good howing
