SPLENDID OPINION
 0F OLD DOMINION
Excellent Story of Recent Results in Mines and Shelter and Predictions of Future of the Company in the Eos ton News Bureau.

The following excellent story of Old
 Dominion in the Boston News Bureau
 is apparently the result of the recent
 visit to Globe of w. P. Bartholomew, the editor of that splendid financial and mining paper:
 'The Old Dominion mines in Globe will, in my opinion, develop into one of the largest mines of the eountry-a hundred million-pound producer"
 This statement is from an authority on Arizona copper properties, man who has visited the Old Dominion many times and whose word always carries weight in eopperdom.
 Apparently the Phelps Dodge inter ests have been working along lines of developing the Old Dominion into such producer, for all construction has been laid out upon large scale. Yet the progress made at the mine end has sur prised even the Phelps Dodge people.
 Notwithstanding that about $3,000,- 900 has been expended within four years, above and under ground, practic- ally all of which has come out of earn ings, the mine has caught up with the shelter capacity, and plans are now be- ing carried out to nearly double the present capacity of the plant.
 In the meantime the Old Dominion has been obliged to refuse treatment of all custom ores except such as carry an excess of the needed sulphur for Aux ing, and it has been unable to treat all of its own ores brought to the surface. This has resulted in stock pile of about 15,000 tons, in addition to an old slag pile which the management has been endeavoring for some time to re- smelt. This pile now contains about 200,000 tons of old slag averaging 21a per cent copper-a matter of 10,000,00O pounds of copper. The management is desirous of eliminating this old slag pile, as the space is now needed for dumping ground.
 The underground development, both in the West country and on the 14th level (1,035 feet deep) assures the con tinuity of the ore bodies and the per manency of the property for many years. The West country developments are of extreme importance, as other than the fact that $l0,000,000 worth of ore is already reasonably in sight in this section, although now unavail- able because of the heavy flow of wa ter, they indicate that the territory has been barely touched.
 It was generally thought that fault cut off the ore in the West country. Developments under the Phelps Dodge have exploded this theory, however, and now the West country is expected to be the richest part of the mine.
 A leading Phelps Dodge mining inter- est is authority for the statement that the underground developments in the Old Dominion mine for the last two years have added $2O,0OO,O0O of value to the property. This estimate is based on the fact that $1O,OOO,OOO of ore value is reasonably within sight in the West country and $lO,0OO,OOO on the 18th and 14th levels.
 It is only a question of enlargement of reduction works. It was originally expected that the Old Dominion con struction costs would practically cease after an expenditure of $l,5OO,OOO; this grew to $3,000,000, however, and it will probably take another million to meet the mine's growing necessities, and most of this work has been contracted for.
 Originally the shelter was modelled for three furnaces, but fourth had to be added, and fue dust chambers and stack originally built to care for three blast furnaces have been overworked. caring for four. Now a fifth furnace has been installed and will be blown in before July 15, but the 1ue dust chamber and the stack are at present to care for five furnaces. and one furnace will have to be carried as "spare" until the chamber can be enlarged and new stack built. An. other blast furnace has been ordered.
