NEW METHODS IF LOADING IRE
 ON CARS
Within Six Months Copper Queen Company Will Have a Simple and Economical SyS- tenn in Operation at Mines.

In line with the progressive policy of the mining companies operating ln the Warren District it is probable that within twelve months new system of bringing ore from the stopes to the surface and loading 1t in the railroad cars will be in operation at all oi the Copper Queen properties. The plans fo- the new system have been formu- lated and steps towards theIr ccn- summf ton are now in progress. In various mining centers through our the country what is known as the sLlp system of hoisting is in opcra- tiCn, and has been found to b" EUt only more economical, but much more satisfactory way of getting the ore to the surface, than that of handl- ing it as is the custom here by means of cages. For a long time the matter of inaugurating this system in the Warren District has been contem- plated. but it was only short time ago that it was finally decided to make the experiment On account of the sticky character of much of the ore mined in this district it was feared that the skip system would be fail ure, but it is now believed that a sO- lution has been found.
 When installed here the new system will entirely change the present sys- tenn of operating the mines. In the first place the only shaft through which any ore will be hoisted will be the Sacramento, which is admirably located as a central point to work to- wards. Running 10 the Sacramento shaft under ground will be the series ,E a-;F nh hn 5rraf of various portions of the properties will be handled by means of electric power. which will be supplied from the new power house now under course of construction. Reaching the station on the various levels the ore cars will be dumped automatically in- to what is known as a pocket, in the shape of V, the apex of which will be flush with the line of the shaft. At the apex of the V there will be a shute. What is known as a skip, be- ing nothing more than a large bucket will be lowered from the surface to the mouth of the pocket. and after be ing filled will be hOisted to the sur face Arriving at the top the bucket will be dumped automatically. it's con tents falling on a belt running in a horizontal direction. and revolving continually. The ore will be carried on this belt directly over the railroad cars. and will be dropped into them as the belt revolves. This completes the moving of the ore from the stopes where it is mined to the cars in which it is ready for transportation to the smelters, saving not only time. but q great deal of labor.
 In order to carry ont these plans an immense new NOrdberg hoist with a capacity of 1000 tons daily has been ordered, and the specifications require its completion an delivery within the time during which it is believed ali de tails can be prepared for the installa- tion of the new system. Steam will be used for power at this shaft.
 Under the new order of things the remaining shaft will only be used for the purpose of lowering and hofsting men and supplies for the undergrourd l workings. At these shafts the hoists will be operated with compressed air and what are known as the dinky cages will be run by electric power
 The reason why this system has not been used here before was on account of the sticky character of much oi the ore, making it very hard to
 
 belt. This problem. 1t is thought. can be solved by mixing the dry and sticky ores. It is entirely an experi ment. though. and will probably be in oDeratioE within the next twelve months.
 The new electric power house which will be located on Sacramento Hill about midway between the Sacra. fh4 and from which the various mines will be supplied with light and power will be completed within six months. Al the present time the greater part oi the work on the foundations has been completed Orders have already been placed for the boilers and machinery the former being promised for de livery within sixty days, and the latter within ninety.
 The Car shaft, which for severa weeks was closed down for repair: is now in operation again with a ful force of men. This shaft has been en tfreiy retimbered with treated timber and is now in the best of condition new and larger hoist has also been in stalled. The completion of the repair at the Czar places all of the Coppe, Queen Company's shafts in practicall,  perfect condition. the Spray and Hol brook having also been thorough. overhauled within the past six months
 The construction of the electrica department of the machine shops progressing rapidly. and 1t is expect ed that the work will be conslete within the next forty days. This de partment will be an extension of tn machine shops, affording means fo the big heavy cranes, carrying tn massive machinery. to be run right ir to the shops, where necessary repair can be easily made. The foundation for the extension are now practicall finished, and work on the superstrus iure will be started within a shor time.
