SmeIter Work Goes On
 Rapidly And Assumes Form.

March and layman can now begin to get an impression of what has been done during the past three months, and what may be expected before the addition of the reverbatory furnaces and the McDougal roasters are ready to go into commission. During the month of January there was a large force of laborers employed in excava- ting for foundations and pouring the concrete foundations into forms set for them. Now the foundations have been practically completed for everything except the two reverbatOry furnaces and this work is in progress and mak- ing good headway. The reverbatory furnaces will each be one hundred feet in length and will lay north from the original shelter building.
 The tunnel in which the electric slag cars will run to the north end of the furnace has been completed and the concrete lining is in place. On the top of this tunnel will be set the boiler plant for the addition.
 Structural steel workers are now making music on the building for five McDougal roasters which are to be installed. This building will accomo- date six roasters, though only five are to be installed at the present time.
 All the concrete lines pitts in which will run the conveyor belts which will carry the concentrates for roasting to the top of the tall roaster building in- to bins for their reception have been completed.
 The material for the steel trestle over which ore trains will be brought to the roasters has not arrived. The grade for the track which will connect with the steel trestle on the west side of the plant has been completed since January. The grade ends with a con- crete abutment which is nineteen feet high.
 The concrete foundation for the great stack which is to be erected for the accommodation of the roasters and reverbatories is complete This foun- dation consists of solid piece of rein forced concrete sixty feet in diameter and eleven and one half feet thick. In the center of the top of this founda- tion is left a receptacle about two feet square and one foot deep into which will be placed the history of the Cop per Rueen shelter. with the names of those responsible for it's creation and operation to the present time, a de- scription of its various departments, etc.
 The title for this stack, which will be 300 feet high. are now being re- ceived, the first car arriving yester- day morning. This tilling comes from New Mexico, where it is specially manufactured for the stack. A con- tract for the erection of the stack has been let to New York company and the workmen are expected to arrive within the next two weeks. It is esti- mated that it will require eight men for ten weeks to complete the stack after it IS stated.
 The new dust chamber has been completed, as also has the new dust hue, which is carrying the fumes from all the converters into the chamber.
 The two new turbine engines have been put into place on their founda- tions in the power house, to be used for generating the electricity which has been contracted to the Fl Tigre company. to be transmitted by the mining company to their property at Fl Tigre, Sonora, distance of seventy two miles. Each of these engines will | provide one thousand horse power, and | will be run by the steam exhaust from the blowing engines in the same build | ing. The electricity will be carried | by an immense underground wire, two | inches in diameter for a distance of | three hundred yards to what is called | transformer building being erected | by the El Tigre company. This build ing is being built under contract by D. | N. Darling, the Douglas contractor, who also laid the tiling in the new dust chamber building for the Copper Queen Co. The transformer building | is 28x48 feet and is of the most sub- | stantial character. From this build | ing the electricity for the Fl Tigre | power house, seventy-two miles away will be transmitted. The transmission | line is now nearing completion for handling this electricity.
