Tired of Inactivity.
 The statement of officials of the company relative to the resumption of development is simply that they have decided that it is time to replace in activity with activity The former came about in 1912 because of the large overhead cost which Denn oper- ations would require if they were to go ahead and take care of the in creased water. The low price of cop per in that year and the outlook for still further decline in the price of the metal, did not encourage the invest ment of the greater capital that had to be contemplated. Since 1912 the Junction shaft of Calumet & Arizona has been lowered to the 2,000 level and a considerable part of the water burden of Denn taken away. It has also been demonstrated that there will logically work out a joint method of handling the Denn flow that will per manently reduce costs from the high figure that appeared to he necessary of contemplation in 1912. These and more attractive than ever in its his tory. Since it cut the lime at $40 feet in the early days of it's develop ment, Denn has been considered in the way of making one of the biggest and richest mines in Arizona. Ore of leached character on the 1000 ana HOO levels, with the 1250 and 1850 areas showing large areas of this char acter of ore, with some sulphides and native copper. and with 12 per cent to IS per cent on the 1900 level, much en- hanced the public esteem of the prop erty. Carbonates and oxides make up the bulk of the total of its re- sources to the present time, and are figured to provide on per cent aver age Resumption of development in the Denn is accompanied by the cer- tainty that it will partake of the high est of engineering efficiency and that there will be plenty of money forth. coming for the conduct of work and the equipment of the property for pro- duction. If $1,500,000 is not enough, those holding the greater part of its securities will have no difficulty ll furnishing whatever more may be needed. Under all of the circum- stances the return of the property to activity is the biggest thing of recent occurrence in association with the copper mining industry in the state.
 The ore haulage tunnel enterprise of United Verde Extension will give to the Verde district its second great d livery tunnel. United Verde put in the first and is operating it with con stantly increasing advantages. The United Verde tunnel reaches out into the valley from the 1000 level of the mine. There is mining both above and below the tunnel level At its portal it delivers the ore of the mine to bins from which there is direct loading to standard guage cars f,ir

By that time United Verde Extension will have its mine in shape to make full use of the traffic way. and it is expected that its new smelter will by then also be ready to take all of the ore that the mine will be able to output under the ad vantage of it's advanced development
