Detailed Description of Improvements Under Way on Large Plant
 At That Camp.
From Sundays Daily)

dated Arizona Smelling company. It
 has been remodeled and reconstructed
 under the supervision of General Man
 ager B.. H. Bennetts and Chief En-
 gineer Center, with an eye solely to
 affording economical operation and per
 maneney.
 Busy, bustling activity, was the
 scene that presented itself to the
 eye of the Journal-Miner representa- tive, who visited the plant at Hum boldt, yesterday.
 The work of completion is being rushed at high speed, and all of the available force that can be obtained in that locality is being pressed into service. Large piles of heavy timber, innumerable varities of cast and wrought iron, may be seen spread out in orderly heaps all over the large tract of ground occupied by the company.
 Theodore L. Center, chief engineer of the plant, very kindly showed the visitor through the workings, ex- plaining every minute detail, dwell ing particularly on the great number of improvements effected since the smelter came into the hands of the new company.
 There is hardly a stick of timber, or a piece of iron, that has not had to undergo rehandling, or else entire rebuilding, and in addition thereto, many new methods have been intro dueed
 New System of Ore Bins.
 At the present time, when the ore is received from the mines, it is | dumped into a series of bins having | a capacity of 5000 tons. These bins have been remodeled, and are equip ped with new Appropriations, per hitting the ore to be dumped into the ore cars when required. The bins are on a very high angle, in order to permit of the passage under meath of these ore cars, each of which has a capacity of two and one-half tons. They are fed through a line of chutes connecting with the bins, and after receiving their load, are shot through a small radial tunnel and then up a steep trestle to the top of the storage bins. The stor- age bins are all practically new, and are about three times their for mer size. They have a containing capacity of 7,5OO tons.
 The cable-haulage system, the same which propels the ore cars from the receiving bins to the upper part of the trestle, is an entirely new inno- vation, and eliminates the use of from ten to fifty men, whose work with the old company was to shovel and wheel the ore from one series of bins to the other.
 Superintendent B. H. Bennetts' Idea.
 This system as it now stands is a child of the brain of the ingenious as well as very practical superintend- ent, B. H. Bennetts, an old and ex- perienced smelter man, and it is said of him that he has no peer in his chosen profession. MT. Bennetts used the same system to good advantage at Hadley, Prince of Wales Island, Alaska, when he had charge of a large shelter there. The details for this system were all worked out by the engineering force at the shelter, and the contract for building given to the John A. ROebling company of Trenton, N. J. It consists of a con tinuous wire cable, passing around the receiving bins on both sides. up l an incline trestle, past the sampling mill, and over the entire line of stor- age bins, and back again to its start ing point. It is double tracked, and makes a loop around the trestle, with a diameter of twenty-five feet The 1 diminutive cars which run on these i tracks are made of steel, and have a carrying capacity of two and one half tons each. They have inverted ; V bottoms, side dumps automatic de- [ vice, and are so constructed that the , carriage can be mechanically dumped l or reloaded at any desired point I along the route. The loaded cars. in l passing the sampling mill, are sam pied by dumping every tenth car ' into the bins at the mill This sam i pie is carried through the various machinery of the mill, the reject re- I turning by means of elevators to the I reject bins, situated at the opposite ] side of the mill, and above the cable i haulage track. The ear, after being ; relieved of its load at the sampling mill, passes on around the mill under the reject bins, where it is filled : with rejects from former samples, {
