 the general public will have a chance. The Likelihood that present sharehold- CTS will leave anything for the public to subscribe for, however, is a very remote one. Denn stands altogether too high in the esteem of it's present awoners. With the s1,500,000 available Denn will resume research on the 1600- foot level, to which it attained prior to suspending work when the inflow of water largely increased in 1912, and doubtless sink to lower levels. It has been expected by mining engineers that it's really big and rich deposits would be reached between the 1890 and 2000-foot levels, with much possi- ble below the latter deep level.
 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 inac- tivity and activity. The former came about in 1912 because of the large over head cost which Denn operations would require if they were to go ahead and take care of the increased water. The low price of copper in that year and the outlook for still further de- cline in the price of the metal, did not encourage the investment ofthe great CT capital that had to be contemplated. Since 1912 the Junction shaft of the Calumet X Arizona has been lowered to the 1000 level and a considerable part of the water burden of Denn taken away. It has also been demon- strated that there will logically work out joint method of handling the Denn flow that will permanently re- duce costsffrom the high figure that appeared to be necessary of con- temptation in 1912. These and other things combine to make sure more at tractive than ever in its history. Since it cut the lime at $40 feet in the early days of it's development, 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 and HOO levels, with the l25O and 1850 areas showing large areas of this character of ore, with some sulphides and native copper, and with l2 per cent to 15 per cent ore on the 1600 level, much enhanced the public esteem of the property. Car bonates and exides make up the bulk
 Of the total of it's resources to the present time, and are figured to pro- vide an per cent average. Resump- tion of development in the Denn is ac-
 companied by the certainty that it
 will partake of the highest of en- gineering efficiency and that there will
 be plenty of money forthcoming for the conduct of work and the equipment of the property for production. If s1,-
 5G0,000 is not enough, those holding
 the greater part of it's securities will
 have no difficulty in furnishing what

 of the circumstances the return of
 the property to activity is about the
 biggest thing of recent occurrence in
 association with the copper mining
 industry in the state.
 The ore haulags tunnel enterprise of
 United Verde Extension will give to
 the Verde district its second great de-
 livery tunnel United Verde put ir , 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 i mine. There is mining both above anC below the tunnel level. At it's porta
 it delivers the ore of the mine to bins from which there is direct loading tC , standard gauge cars for the smelter
