 famed by the cool currents of th
 upper air stratas, Prescott and lava pal county in general are immun
 from the enervating effects of tn
 Summer caloric, that energy sappin: visitant which at less-climatically-fav ored points throws the human ma chine into low gear and tones down it speed to meet the exactions of thu Sons of Rest. In other words, min ing and general activity is not lessen ed here as midsummer draws near to the contrary, it is increasing as tht following summary of work at tho mines will go to show:
 Operations have been resumed d the old Holmes mine in Black can yon. The property was recently talk en over by Willard Bonderant ana associates Of Los Angeles, who pur pose to develop it at depth. The his tory of the Holmes mine dates back to the early eos, and its record as a producer Of high grade gold ore runs concurrently herewith. Early devel' opment was prosecuted by means oi a tunnel and disclosed free milling ore that sampled as high as S2OO per ton in mill-run lots. The general av- craze grade of the ore at that time mined is said to have been S60 per ton. It was reduced at a fair profit in small mill erected on the proper ty. A wagon road has been built connecting the mine with the camp Of Mayer, and the old workings are now being rehabilitated as a prelim- mary to extended mining operations.
 White Spar Operations.
 A. E. Moynahan, of Denver, Colo, who recently purchased the White Spar group of three patented claims from Ed Block of this city, is devei- oping the property quite as much with a view to retaining the high per cent of antimony contained in the ore as to retaining its high silver con tent. Mir. Moynanan. who is mine inspector of Colorado, has interested other Colorado mining men in the proposition and intends to engage in extensive development work. The property is located near the Climax mine in the Hassayampa river coun- try and in past years produced con siderable tonnage of valuable silver ore.
 Mining conditions in the Loma Prieta shaft continue to be satisfac- tory and to indicate that it is being sunk in the main copper ore channel of the Copper Basin district. The body of chalcopyrite ore encountered at depth of S5 feet continues to fill the vertical shaft and appears to be a fixture therein. Each days develop ment work records an improvement in the ore body and tends to more demonstrate that the Loma Prieta Mines Company is the owner of one of the most valuable partially developed copper proposi- tions in Yavapai county.
 Bradshaw Tunnel Work.
 The deep development tunnel being driven to the heart of the Bradshaw mountains by the Bradshaw Develop ment Company, recently tapped "blind" deposit of copper orc of prom ising possibilities. and is in general demonstrating the worth of the orc bodies of that section. Primarily t is being driven for the purpose ot opening at depth the deposits of high grade gold and silver ore opened nearer surface on a number of well known properties. When completed it will nave d length of l5.OO feet  will have tapped at a depth from 800 to 1000 feet the Lin coin, Fairview, Nelson. Crown King, War gle-Glajiator, Del Pasco, Old Reliable. Wildfower and other mines.
 The directorate of the Jerome-Vic- tor Extension Copper Company, own CT of the Haynes group in the Jerome district, has been completed by the election to tic board of William T. James, president of the Queens Coun ty Savings Bank of Flushing. N. Y. The personnel of the board includes some of the most prominent bankers and mining men of the Lake Superior copper belt Work on the oompany's property was started last May and Is being prosecuted with gratifying re- suits under inc direction of George w. Salisbury. for a number of years a member of the engineering staff of the great United Verde mine.
 Tiptop Mine Busy.
 Seventy-two per cent tungsten ore has been operei in the Tiptop mine
