Th e factors of moisture, fineness, un lformity, sulphur, lead, iron and silica in th emixture have been pretty thoroughly discussed and their limits defined. More thanalready stated, It is to be noted that somezine is usual in all ores and concentrates;up to 3 or 5 pe r cent its effect is certainly no t more harmful than possibly givinghigher sulphur in th e product. Sulphide orescontaining more than this amount shouldbe milled for it s separation. Flue dust wellIncorporated into th e mixture does no par

The blast regulation at th e unit is moreto compensate for faults elsewhere than as

When the operation' of roasting an d s;ntering Is completed or has been carried asfa r as practical, th e discharging takes plaCE)according to the particular equipment In'stalled; any particular cost fo r this partof th e work should be eliminated. Thus,at Midvale, th e services of th e ra m ma nan d the crane chaser ar e practically de voted entirely to this detail, involving a direct cost of 4 5c. pe r ton. With th e Greenawalt pan, which is in unstable equilibriumwhen loaded, a slight push inverts i t an dth e cake falls out, breaking on th e angleirons below an d sliding off Into th e stee lboat or skip placed below, ready to betaken to th e breaker.

Th e Dwight-Lloyd machines ar e supposedto work equally simple and with th e sameminimum cost.

Nothing more complicated or costly ofoperation will be tolerated in future design;even for these simple cases on e must bearin mind th e ,properties of th e material an duse no material or construction whichwould be quickly damaged by th e nard,rough an d hot cakes in their entirety if,perchance, they should n ot be broken asexpected.

Referring to th e data given, th e laborcost of th e roasting operation is given as20.7c. a t on e plant, and for th e other plantwe may likewise find a su m of similar itE-\nswhich will amount to 6.3c. For a Greenawalt pa n we may properly estimate that 2men, whose pay equal $4.00 an 8-hour shift.>will be able to dump an d load a pa n every15 minutes, or handling a tonna'ge of 60tons per 8 ,hours the ir labor wlll cost 6.7c.pe r ton, I f we add to this the services of

"another ma n to clean grates an d th e finesfrom beneatii the grates we shall have acost fo r labor of approximately lOco pe rton. This item of operating cost fo r th eDwightLloyd machines might be supposedto be somewhat less.

To furnish th e blast or suction requiresmore power than tile su m of all the otherpower requirements in the roasting department.

If . l ~ t us say. 100 continuouB horsepower is required to supply ai r to treat300 tons of material p er 24 hours a t a

the electricity, this item is in so much avariable factor; th e price of coal a t mostlead smelters, du e 'to th e long haul, willhardly be a t a low figure an d th e price ofpower will probably be much greater thanin this last instance. In the case of tw oplants already considered th e cost of, powerha s been estimated a t 9 an d lOco pe r tonof production, respectively.

level of the "Martha" vein, "Allie" Miningcompany, places Gilmore on the Jist a tleast several miles ahead of all competingcamps in the state for honors in th e yellowmetal producing line, an d i t would aprearthat this property which is already shippingou t three cars weekly from other worKingsthat nets $28 gold pe r ton, has an inexhaustible fuud of goid, which is graduallycoming to light through systematic development. Two years ago this paper ha d th ehonor of chronicling a big gold find inthe "Martha," which find, subsequent workings have proven to be permanent to date.Th e depth at which th e recent find wa smade and th e values expres3ed on the button scale should ,be regarded with equalsignificance ta r removed f r o ~surface out,crqp picked specimens for assay purposesonly. As nearly as can be determined, th eor e streak, the matrix of which is manganes e an d oxides of iron, is eight inches wide,the entire masS broken down and withoutan y attempt a t sorting, averaging $1,500 pe rton, gold.

I N V ES TMEN T OR SPECULATION?

In answer to an inquiry as to what constituted a good investment, an ellstern l'ankIng house is quoted as saying: "We do no tconsider an y mining stock a good investn ~ e n t . All mining stoc\!:s ar e speculative."

Th e answer was brief, almost brutal;but, wa s it correct?

H giltedged dividendpaying mining stockis no t a good investment, where ca n on8be found? I f th e line is drawn on firstclass mining securities in what list shallwe place real estate, industrial stocks an dbonds, mortgages an d railroad securities?I f we were to reply upon th e statementof this banking house, even governmentbonds ar e nothing more than a speculationif dividendpaying stoc\!: in a heavy an dregularly producing mine is regulated tothis class.

I t is certainly tough to have to doaway with mining3tocks a'S an investmentan d to be compelled to regard them as

purely speculative. Some people may attach some importance to th e opInion ofthe banking house in \l.uestion, bu t therear e thousands upon thousands of investorswh o would no t turn down mining stocks infavor of any railroad, industrial of manufacturing seCurity now on the market. Infact, it would require more argument thanthis ea'Stern institution could advance for=t century to convince them that ",hares ina good, substantial mining company are no tthe best, th e safest, and the most legitimate investment that can ,be found.

I t ma y be well to tell th e tenderfootand the farm laborer that stock in a regular

dividend-paying mine is not a good investment, tha t it is only a speculation; but i tis !l. waste of time to give such an an'Swerto intelligent busines3 men and capitalistswho have a real knowledge of the magnitude an d legitimacy of th e mining industry,an d who have long ago been impressed withth e fact that no more profitable avenue forinvestment exists. I t would be difficult toconvince a shareholder in th e old Ontario,of Park City, a mine that ha s paid nearlyfifteen millions in dividends, that stock inthis com.pany was not a good inveGtment forhim; and th e sa me ('an be said of ownersin th e stock of the Silver King Coalition,which ha s nearly thirteen millions, in dividends paid, to it s credit.

~ O fth e boys ou t in the hills whoped th e walls of their shacks withnining share certificates. Well, it1teresting story, an d I will relate

we ar e resting befOre pushing onnext divide. Several years ago I

nped out in the Aviation range andLng some work on a prospect I ha dsometime bRfore. I was. all alonelonesome an d tw o burros, and ha d

work one afternoon when a ma nong with a covered wagon, a muleame horse. Th e man had hi s wifem, who was suffering from troubleer heart, an d an effort wa s beingo ge t to th e nearest town so thatvices of a doctor might be obtained.ays before the horse had gonehd progres'S had been so slow thatD:S for the trip had boon almosted, an d i t wa s ye t fifty mile:. torest town. I felt sorry fo r th e out-especially so as the couple - seemed

30 poor an d up agamst it; and so,he man offered me 10,000 share'S Instock, which cost hi m a cent a share

)Rths before, for on e of my burros11 up with hi s mUle, an d a sack ofIld side of bacon, I made the trade,h I ha d no us e for th e stock an dlxpected to ge t a dollar for it . nut,

th e deal, al l th e same, an d th eas endorsed over to me, an d th e ma nife left my camp rejoicing, for aJurro wal; a much better mate for an_mule tuau a lame horse, although

a sorr:'-looking team. I put the'Stock in a tin can an d chucked it

hole in the wall- of my cabin, neverg of ever 'Ieeing It again, and hardlyoering, even, the name i t bore. Six

later I hall occasion to go to th e. mining camp, sixty miles away. It $een a paper for so long that I ha dforgotton how to read; so, th e firstdid, when I go t Into camp was to

copy of th e Bunkerville Pusher. Th el'3.dline, in eighteen point type, toldrong advance In Gumbo. At first th eli d no t strike me as ooing anythingthe ordinary; bu t I ha d a subconsci3ling that caused me to re-read th e~ . Then it came to me that I ha d}umbo stock, an d I continued th e arvith renewed interest. I t seemed,

rhat I could g'lther, that th e GumbolY ha d made a fabulously rich _strike,1t from a few cents a share th e stockdvanced, by ieaps an d bounds, to~ , s h a r e .You ca n be t your sweei;at I became mightily interested in

at once. In fact, I felt as i f Gumboy affinity, an d th e way my affection'Sut to that ol d ti n ca n in th e hole in11 in my shack out in th e hills, woulda Reno divorcee look -like a nickle. hole in it ; an d th e pull it s conad on me wa s greater than the attracIe north pole ha s fo r th e magnetic

needle, for I wa s back home before midnight,an d it was with trembling hands that I l i t acandle and sought th e spot where I ha ddeposited my Gumbo stock. To my delighti t was there all right, although th e m,iceha d nibbled around th e edges of th e certificates. The next day found me in th emining camp again, an d when the stock exchange opened Gumbo ha d climbed to $3a share;. bu t I le t my block of 10,000 'Sharesgo at that figure, an d that night my bankbalanCe of $3.60 ha d been swelled by th eaddition of $30,000, less the broker's commission. I could have gotten more, th e nextday. for th e stock went to $5, bu t I wa swilling to let the other fellow have ach.ance. an d wa s fully satisfied in takingdown my profits. Within a month th estock wa s selling fo r $15 a share. Withinthree months th e company b e g ~ npayingdividend'S, an d ha s since paid. mort) than$20 a share in profits. Th e stock is nospeculation now, no gamble, bu t a safe Investment; and, while .I made a bunch ofmoney by a small speculation. I have always felt that th e whole thing wa s entirelylegitimate, although It might be termed'taking a chance: 'gambling,' or a 'speculation.' "

"I want to tell you, Old Long Ears," concluded the prospector, "No ma n will evermake a success in life unleS'S he takes 11-chance. Th e ,baby will never learn to walkunless he ta;kes th e risk of a fall. Youcannot know i f th e girl of your ChOIce willhave yo u unless you chance th e risk of arefusal by proposing; an d no one can benefit by the advance that may be made inany of th e many lines of stock offered onthe board unless he has had the courageto bu y a little of it while. being sold fo r asong that you can almost sing for yourself.To succeed in life one mu,st gamble alittle, on e must take a chance, an d on e mustby willing to speculate once in a while;an d there yo u are, an d then some."

SAL.E OF URANIUM CL.AIM.

(News, Grand .Junction, Colo.,Almost a sensation wa s created in Grand

Junction yesterday by the announcement ofth e sale of a vanadium an d uranium claimnear Gateway by King and Loveridge, prospectOI'l3, to an English syndicate for $9_000In cash. Th e claim was only one of th e

half dozen owned by th e tw o men. . Th eEnglish people will start taking out ore atonce an d will start hauling as soon a'S aroad between Gateway and Grand Junctioncan be opened up_ Th e property purchasedincludes a ledge of vandlum ore averaging5 pe r cent and running 1,200 feet long an dseven feet wide. How far back into th emountain it extends no on e knows.

Th e closing of th e deal has acted \}S astimu1us to th e Gateway people in Workingfor a passable road to this city, anll J. H.Denby, a prominent mining ma n an d prospector of Gateway whG wa'S in th e city yesterday, conferred with Commissioner ofHighways Rankin and L. W.

Mr. Denby is very well posted and is a representative from th e settlers in th e Gateway region a'Sking that the Gateway bridge be installed.

I t is estimated tha t the property loss inth e United States from fires during thelast thirty-three years totals the enormoussu m of $5,147,253,724. Th e magnitude of

th,is loss is almost inconceivable, ye t an idea.of it ma y be gained from th e fact that thissUm is equal to 1-25 of the present wealthof the United States. This sum, i f in silve r dollars, placed side by side, would reacharound the earth nearly five times, or tocarry them would require a freight train38 lh miles long, if made up of cars of 60,000pounds capacity an d 40 ft. long. Fancy sucha train on th e tracks along th e Hudsonriver, an unbroken llne of cars reaching aquarter of th e distance from New York Cityto Albany, and every ca r loaded to its maximum capacity with silver dollars, and thenyou have an idea of th e wealth that ha sgone up in smoke in th e United States inth e last thirty-three years.

This enormous loss certainly drives home

th e conviction tha t the fire hazard Is of nosmall magnitude_ I t is 'imperative therefore that the most approved an d up-to-datesystem fo r fire protection be installed. Manyplants ar e now equipped with automaticwater sprinkling systems an d protection isafforded provided th e water pressure is main'tained. In the case where th e pumping installation belongs to the plant, this requirement means tha t the motor and control apparatus must ,be absolutely reliable so thatno fault will develop and make i t necessary to shut th e motor down an d stop th epump.

A fire pump motor with it s control panelis designed fo r emer.gency conditions an d

consequently is seldom operated All operating parts of th e control p.anel shown inFig. 1 have bearings provided wi til noncorrosive Itarts so that they cannot rust on

account of long disuse and prevent the moto r from operating at th e crit ical time.

Th e cdIDplete panel is enclosed in a splashproof case which effectively protects it fromdripping water an d also prevents the entrance of water if a stream from a fire hose

should strike it. Th e panel is mounted onfour pipe .supports so that it cannot bereached by 'Water accumulating in th e basement where th e panel is generally installed ,

I f desired the motor ma y be starthand by means of the operating leverth e right of the contactor. This m

forces the contactors to close in their psequence by m,eans of a caJm shaft .
