 The output of the Old Dominion for last month was ITS tons. remarkably good showing.
 The June output for the Arizona Cop per company was HAS tons of Besse- mer copper.
 Wm. Heating. who owns a group Of splendid claims in the Coronado noun tains, was in town this week laying in supplies for his camp. He owns some of the richest claims in the camp, and has made many shipments of ore aver aging 30 per cent, which is good ore in any camp.
 The Era is in receipt of a letter from George H. Chapman. who is now at Cananea, in which he states that the Cananea company is now shipping 100 tons of copper daily, besides from 4 to 6 cars of rich gold and silver ore When the new concentrator is com pleted, which is now in the course Of construction, the output will be mate rially increased.
 I. N. Stevens. superintendent of the Chase Creek Copper company. came in from the mines last night, and reports that the tunnel has now penetrated the vein twelve feet. and that the ore is improving as depth is gained MT. Stevens is now thoroughly convinced that he has struck the Longfellow lead and as it is from 40 to 50 feet wide on the surface, he expects to open another big mine for the district.
 George T. Millner, the mining en- gineer, who is now looking after the business for the Weaver mines, was in town this week arranging for another shipment, which will be made in a day or two. He expects to soon put up hand jig at the mines which will con- centrate three tons into one and thus not only make a higher product. but also save money in transportation and treatment charges. This Will be the first hand jig in the district, but it will doubtless soon be followed by others
 Ambrose Burke, who is interested in a large group of claims on the west side of the Coronado mountains. man. aged to find time to come to town this week on important business. He is now opening up the Plate group of claims with tunnel which is being driven in on ore. The Plate veins are among the strongest in the district. and have produced some remarkably rich ore. He is also interested in the Bo- nanzo group. which adjoins the Plate group, and which also make good showing.
 Duke Await. who, in connection with Hon. Ben M. Crawford. is opening up a group of claims in the Gold Hill dis trict, reports that the mines are a great surprise to every man who visits the camp. The ore averages more than S20 gold and about 30 per cent lead, making it a most desirable con centrating or smelting proposition. The vein has now been opened to depth of 250 feet. and the ore holds a uni form value all the way down. It is the most promising gold property so far discovered in the district
 Manager Sweating. of the Polaris company, who has been east for some weeks past in the interest of ;he con- pany, is expected to arrive home to- morrow. Work has been progressing steadily at the mines during his ab- sence, but it is expected that the force will soon be materially increased. Re cent development work on this prop erty has been most encouraging, in fact the mines are making most won derful showing. Aside from showing some of the richest gold-copper ore in the district the management has block ed out a large amount of good grade fr aH of he ly- ings.
 w J. Slee, of Australia, arrived in Clifton a few weeks ago for the pur- pose of installing Hancock jig in the concentrating plant of the Arizona Copper company. The jig has now been in operation about four weeks, and is proving itself wonder to mining men and others. It is capable of handling 40 tons an hour when put to its full limit. At the present time it is hand ling $50 tons in twenty-four hours It does the work of seven jigs which were formerly in use in the plant, and re- quires the same amount of wa;er as two of the old jigs. l. requires less than half the room of one of the old jigs. It does it work equally well If not better than the old machines. In fact it is an all-round wonder, but with all, a very simple machine Those statements win doubtless be regarded with suspicion by mining and TilI men generally, but Archie Morrison, super. intendent of the concentrating plant. is authority as to their correctness. MT. Slee claims that he can make the jig take the place of the first vanner room, thus making an additional great saving to the company This is the first Hancock jig in operation in the Unit. ed States. though they have been ia almost universal use in Australia for many years. Mir. Hancock. who in vented the jig. is a man of much mesrs and is in charge of a large pronersv at Broken Hill. hence he had neither the time nor incentive to intro duce the machine throughout the world This machine will not only chea-an ro'ning in this district bu;
