Show Graphite Imports Are Cut Off ty. rk " - Stimulation of Mlnlpfl f Fibrous Variety Va-riety In United 8tates W)ll Result Ample Supply Available for Pencils, Lubricants, etc. Although the Vluo ot tl,Q BrtinUUo Imported Into tho Unttod States In 1913 was almost twice tho domestic production, tho cutting off of tho for olgn supply should seriously affect only the cruclbloN Industry. Thero Is an ample supply of graphite In this country suited for stove polish, foun-dry foun-dry facings, and paint pigments, and large deposits of amorphous graphite, in northern Moxlco, now: comparatively comparative-ly peaceful, are controlled by Amerl-can Amerl-can Arms and can be depended upon for supplies ot graphite. for pencils, lubricating material, and many other uses. Moreover, graphite Is now being be-ing manufactured In tho olectrlo fur-naces fur-naces at Niagara Falls In amounts far in excess of tho domestic produc Hon from natural sonrcos, nnd this graphite Is oll adapted for most of th'o uses to vhlch guphlto la ap- pllod. .... . Tho graphite for which wo depend mainly on foreign sources Is that M used In the manufacture of crucibles and other refractory products, but as these uses probably consume over half of tho graphite used' in this country, such dependence Is a matter of no small Importance. Moreover, tho manufacture of cructblo steel "re-quires "re-quires graphlto crucibles. Tho grn-p phlto used In crucible making has been brought largely from tho Brit-, Ish island ot Ceylon, although wltti-in wltti-in tho last tew jears somo busbcen brought from the French Island of Madagascar. This graphite Is llakj' or'flbrous and for this renson Is cm-. Inently adapted totruclblo making. For this use it has never met with serious competition from domestic graphlto. Tho earthy amorphous graphlto mined In this country nnd tho graphite manufactured at Niagara Falls are not adapted to this use and as a rulo tho expenses ot concentrating concentrat-ing domestic flake graphite has been prohibitive. Nevertheless it Is to the domestic supplies of flake graphite that this country must look In the ovent ot foreign supplies being cut off. Practically lnoxhaustlblo supplies sup-plies ot this mateilal aro known to occur In New York, ow Jersoy. Pennsylvania, North Carolina, Alabama, Ala-bama, Texas, and some other States and are fully described In tho repoits of tho United States Geological "Survey. "Sur-vey. Similar deposits aro abundant In Canada. The graphlto In these deposits occurs as small flakes In rocks composed mainly of quartz, feldspar, nnd mica, tho graphite constituting con-stituting 5 to 10 per cent by wolght. Several plants are now engaged in working such deposits, and many others now Idle could bo put on a producing basis In a short time anJ at little expense. Although tho pro duct might not bo equal to the Ceylon Cey-lon graphite In all respects for crucible cru-cible making, there is no question that It would be adequate for similar graphlto has for years been successfully success-fully used In Germany. Another American resourco Is the graphlto deposit near Dillon, Montana. Mon-tana. The graphlto thero Is very similar to that from Ceylon nnd should bo adaptable for crucible making. mak-ing. Although tho deposit does not compare in size with the Cejlon do-posits, do-posits, it might render material aid In case ot a shortage. |
