per Queen. but Mir. Shattuck de clares that if there is anything of the kind on foot he knows nothing of 1t and there is lack or confirmation from any source The action of the Shattuck company has been puzzling to many people in the district for more than a year. It was known to be the intention of the company to build a reduction works in Douglas; that was given out from Duluth two years ago: ground was secured in the smelter city for this purpose and twice since the production of ore was discontinued in the mine; bids have been asked for and received from the machinery houses for the construction of the smelter, the last bids having been received last July. The property is known to possess grade, but no shipments have been made during the past year, except that taken out in recent development work. s-----s
 At the Denn the work of sinking on the main shaft is being continued and about sixty feet has been made since work was resumed more than. a month ago The shaft is now 1260 feet deep and is still in white lime which was encountered a short dis tance below the 1200-foot level
 C. and 4. and s. and p.
 The most important feature Of the past week in these properties was oil the 1900 level of the Junction mine. In a drift running east from the shaft and in the direction of the Denn prop erty a body of low grade oxide ore cd desd very well by those in charge of the work. While the grade of this ore is low. still the character of the forma- tion where it is found is considered very favorable In this drift consid erable native copper is being encount- cred. The ore output of the c. and A. and S. and P. properties is about equal at the present time and the Douglas smelter is now dividing its capacity to the product of the two companies.
 At the c. and A. smelter four of the six furnaces are being operated. Construction work at the shelter on the plans for the enlargement of all the original 300-ton furnaces to a ca pacity of 800 tons has been stopped and nothing has been done along that line for several weeks. In this con nection there are indefinite surmises and rumors floating around Douglas to the effect that this construction work has been discontinued pending decision on a complete overhauling and enlargement of the plant on a scale much larger than had ever been planned before. Another reason suggested for the stopping of this construction work is that the capaci- ty of the stack now serving the plant has about been reached and that this stack would not accommodate any more furnaces in the C. and A. shelter
 Work on the new office building of the C. and A. at Warren has made excellent progress during the past week. The upper story of this build ing is now practically complete and ready for occupancy when it Is cleansed Painters, plasterers and men doing all kinds of finishing work are rushing and the entire building is expected to be complete by May 1. It Is expected that all the various officers and heads of departments of the c. and A. and s. and P. will be comfortably installed in the new : building, one of the very finest of the kind in the southwest, before the middle of May. Everybody connect ed with the C. and A. offices is get ting ready to spruce up for their new and elegant quarters.
 Saving Flue Dust.
 A new and interesting plan for saving fue dust at the Copper Queen smelter has recently been installed by Superintendent Lee. Notwithstand- ing the various means for separating the dust from the sulphur, smoke which comes from the converters be fore it starts up the gigantic stack, which is 260 feet high, great amount of this dust, which carries a good percentage of copper. was car ried out at the top of the stack and distributed over the Sulphur Springs valley as a Vexatious waste. A pipe eight inches in diameter has been placed on the west side of the stack and extending from the ground to the top of it. This pipe is carried in to the top of the stack and short distance down, into which the as cending smoke. carrying the valuable iue dust, is sucked by an air suction machine at the base of the stack The hue dust 1S brought 10 tne Dasc of the stack through the p'pe and forced into another stack some twen- ty feet in height in which is placed huge seiye which arrests every ! particle in the smoke which finally reaches the atmosphere entirely col ' orless, but not odoriess, being very | strong with sulphur.
 In connection with this plan fol saving the iue dust very many me chantcal devices are brought into use
 for measuring the velocity of the smoke as it ascends the great stack and also the velocity with which il is returned down the pipe. By these mechanical measurements the amount of Hue dust recovered is ac
 curately measured. A technical de scription of this method VII not be undertaken here, but it can De said 10 be working satisfactorily aud pro fitably.
 Sulphur Waste Enormous.
 Those who watch the smoke com ing from the great stacks of the two smelters perhaps do not realize that every day there escapes through the
