L0S ANGELES ID HAVE MINE
 EXHIBIT


 and importance in the United States which has no public reference collec- ton of minerals. ores and non-metalic products of economic importance. Realizing the importance such an ex- hibit would exert in stimulating public interest in mining matters. and feel ing that he Los Angeles Chamber of Mines is the logical sponsor for 'such an exhibit. the following plans suggested by the mineral exhibit committee. have been approved and adopted its board of directors of the chamber.
 It is considered desirable to build ID in Los Angeles two distinct col lections. one an exhibit of Economic Geology. including the ores. petro- leum and other economic productions of the territory tributary to Los An geles: the other a Mining Exhibit. which shal show both the commercial importance and the geology of the Southwest.
 MINING exHieIT.
 This collection will be exhibited on, tables and open to the close scrutiny of the public as 1t Is felt that the . rature Of the collection recessitates its examination at the close range hv those interested n crder to be of f7''l value As it will contsin no spe- cimens of intrinsic value. there should be no terpfation to pilfer. End he Char ber i,ticirates that the public vii! recognize the advantaga of 'his feature and protect the col lection.
 This couecr'on will present sn eroupes srerime-s of the country rocks or walls. of the ore fenosits: samples of the average ore as mined, and snecine-s of high-Srade ore. from the various n'ines of the South west. Sush groun. representing ine-, sor ci: c--fw that are are th each mine senarately. will be evhib- tied on unifcrr ''ard of suitable size. This card will bear a la-ge 'ahe' stating the nare and location nf fhe nainn. and each snecin,en will have a separate label. stating in as Tow words as possible. what it rep rcsants
 Fo~ this e~bihit there will be de- sired the following from each mine: Snecipens of the eou7trv rocks and walls oF the nre denosits. taken where the rock is fresh and undecomposed. If several different rocks occur ir the region of the mine they all should be represented. These specimena should be chipped to uniform size of 3x3iSx1i5 iDchs%. This should he done in the field where there is rlentv of material to select from. The avarneo c~a ~ iba r1i,e should be represented by several fragments rather than by a single specimen. The average assay value of he ore represented should be stated. Speci- mems of the high-grace ore car usual ly be trimmed to the, aforementioned size. but when theis would iniure a specimen the high-grade may be represented by several fragments. This specimen must illustrate the "high-grade" prduct of the mine. and must not be confined to the finest specimen available. It should be ac- companied by a statement of the gen eral value of the high-grade product. Photographs of the out-crops. or other vein exposures. would be acceptable. and for the filing cabinet photographs of the camp and mine Improvements | would be greatly appreciated. Each I specimen must be carefully identi- ' fled as to what part of the mine it comes from and what it represents, | tthe rock species need not be identi, | fed), and the group must be accom- 1 panied by signed and witnessed statement that it is fair representa- tion of what it purports 10 be.
