Lolth of tho geological purvey, and! an oxpert who haB been c'Won to xnralno tbklron cnunt3f1?l,,t? ot intoroeting comment: ""i "Among tho hotter knewu deposits might bo mentioned thosoln llurtvlllo district pf Wyoming and in Fierro, Now Moxloo, both of which aro now being drawn ' upon ; in Pitkin, Obeaffoe, Saguache, Lako and Gunnison Gunni-son counties, Colorado;, iu Iron county, Utah; in noitboastorn Washington Wash-ington and in n number of localities in tho Great Basin region of Novadn aud California. Tbero should bo Inoluded also tho ores of Vancouver and Texada islands, iu British Oolubmia, which aro largely controlled con-trolled by American capital and will bo .used in tho (Jul ted States. Tho samo remarks mny apply to tho Dnrougo and other Mexican deposits. With fow exceptions tho western oros occur along tbo contacts of intrusivo igneous rooks nnd limestone, nnd tho extent to which tho ores follow the contact in depth has not boon shown. Ilonoo tbo estimates of tounago vary within very wldo limits. "Tho iron oro doposits of Iron county, Utah, aro among tho largor aud most typical ot this class of ores. Hero somo 800 pits linvo beon sunk nnd it has boon posslblo In recent dotniled mapping to ostimato with n roasouablo approach to tbo truth tho amount of oro of all grados appearing to tho dopth shown by explorations of natural exposures. WEST HAS LOTS OF IRON. "Using tho Utah deposits as n basis of comparison, aud excluding tho Mexican deposits wblah tho writer has not Beou, tho tounngo of iron oro of all grados in eaoh of tho bettor known districts of tbo west aud ndjacont parts, of British Columbia would not surpass that ot ono of tbo othor Lako Suporior ranges, but it is extremely likely thnt ns deep exploration ex-ploration of tho presently known deposits continues, and as further doposits ore found, ns thoy undoubtedly un-doubtedly will bo, that tho nggrogato tonnago of oro In tho west will equal a considerable port of that ot tho Lnko Suporior region, sad ono would bo rnBh to oonoludo that It is impossible im-possible that an araonut ot iron oro may bo found In tho west fully oqulvalont to thnt in tho Lako Superior region. "If tbeso data approximate tho truth, there Booms to be littlo cause u- of alarm that North America will really Biiirer for Inok of iron oro for a considerably longer period tbnn required for tho exhaustion ot tho presontly known touuago, as estimated by Tornobohn and othors,at tbo present rato of inorooso of produc tion. Tuo time oi exunuBtion is not likely to oomo beforo that calculated on tbo samo basis for tho world's reserves, and probably not then. It may be argued that tho use ot lower grade oros in Europe and England than in tho United States is Itself lovldouco thnt tl.o exhaustion or I reserves is further In tho f nturo for tbo United States than for Europe or -jWou.W f .... 7 IIIGII GRADE OR5 IS LIMITED. "But It becomes moro nnd moro obvious that tho oud of tho supply of higher gindo oros in tbo United Statos Is not Indefinitely In tho futuro nud may oven bo within a single lifetime. Thoro is likely to bo nn iuoreoso in tho tendency to con-sorvo con-sorvo the higher grado ores, and ospooially tho Ocssomer oros, nnd draw mor largely on tbo lower grndo supplies, a toudonoy fnvorod by tbo concentration of control in n fow hands. This tendency has already beoomo well defined, as shown by tho fact that pig iron production has not iu recent years increased ns rapidly ns iron oro nroduction. It Is not at all unlikely that ovou tho next deendo may seo important changes iu this direction. This will glvo values to prcporly locnted low-grade ores. It will ultimately mean higher cost for Iron, changes in tho rolntivo importance impor-tance of processes for oovorsion ot irou, possibly changes In tbo geographic distribution ot different phasos of tho Iron industry, nnd a modification of tho relations of tbo North America Iron trndo with thnt of tho rest of tho world."
