 The Mining Fair has run its successful course, and the magnificent mineral ex- hibits are being packed up for removal along with the show and advertising features which some men from the min ing counties have been inclined to con- demn. They should remember, however that these features and the other forms of popular entertainment gave & needed l diversity to the fair and drew to 1t thousands who were not especially Inter ested in mining, and who received first lessons in 1t there.
 The fair has uuQuestionably done much to advertise and popularize the mining industry in th4e State, and so has served its purpose. It is a pity that a larger portion of the mining exhibit Is not to remain in San Francisco and help form the extensive permanent exposition of the mining resources of the State which would be of so great value to the indus try. Many specimens will go to the Park Museum, and some county exhibits at the State Board of Trade will be enriched by selected mineral specimens and sup plies of the special mining literature pro- vided by several of the mining counties. The State Board of Trade exhibit and office will remain in the Mechanics Pavilion, open to the public, until the new ferry building is ready for it.
 The most notable new mining enter prise which has come to notice in the State during the week is one which the San Bernardino Times-IndeX enthuSias- tcally describes as follows
 San Bernardtno County may soon be able to boast of her copper output as su- perior to that of the Arizona mines, and also boast of properties almost as rich as those of Michigan. J. Irvine Crowell of Corona is representative of some large Eastern corporations which have taken hold of an immense copper deposit ln this county and intend to develop it.
 'The copper deposit in question IS sit uated about midway between Daggett broad by twenty eight miles long. In this belt the gentlemen have located lS3 claims. The ore is unusually rich, run ming IT per cent copper and about Sll gold and SIS silver to the ton. This is an aver age while choice specimens have gone as high as 40 per cent copper. The Arizona that is considered rich. In the belt there has been found plenty of water
 The proposition is purely one or smelting The properties are now in the hands of two rich private Eastern cor porations-the Pacific Copper Alliance Of New York and the United Yucca Copper Mining Company-and another will soon be organized in Boston to cooperate. The properties are positively not for sale, and neither will stock be sold. It Is only rich corporations that can handle copper propositions and especially one sof such extent as this. They will some time short ly, but just when MT. Crowell would not say, commence the erection or lOo-ton smelter for the reduction of their ores 
 Randsburg and adjacent desert dis tricts are joyful over the assurance that plant at Barstow will be pushed to early completion. The plant IS being erected with wise enterprise by the Randsburg Railroad people mainly to develop the district upon which 1t de- bends for business, though the large in vestment will be profitable in itself. few days ago the miners were addressed at Randsburg by Albert Smith, vice-pres- ident of the company, who stated that the new mill, now in course of erection at Barstow, would have a capacity of fifty stamps, with all of the most modern i'm provements in the way of gold saving attachments; with concentrators, and the l addition of a cyanide plant to treat re- fractory ores. This mill Is owned by the railroad people, and would be run. first, in the interest of the Randsburg mines.
 He stated that the company would be able to handle ores of IS low grade as g per ton. and that after the mills had been in operation thirty days he could then tell | IIlOTt Ger ldlIly WIldl lHty cOulQ QO. lie | further said the company would take all of the low-grade ores In the camp, paying for them on the dump; that in three weeks time they would have a man here to go through the district sampling and | buying ore, although they did not expect 1 to have the r'u in operation before the middle of AprtI.
 l It is thought that in a little time ores running as low as s a ton can be treated with profit Regarding the enterprise. a correspondent of the Los Angeles Times iy,arnn nnr+o, event ever yet started for this district There are vast quantities of low-grade ores on every side, some veins running as wide as twenty feet. but just a little too low to be available with any process now within reach. There are thousands of tons of ore here running from s6 to SIP per ton. which will immediately have a com mercial value"

It comprises sixty large pages filled with half-tone pictures of mines and mining men of Shasta.

 Tuesday the first shipment of quartz crystal came down on the narrow gauge from near Mokeumne Hill, says the Lodi Review-Budget Each piece was encased in heavy plank boxes and altogether the shipment weighed 24.000 pounds. It was consigned to Tiffany. the great New York jeweler king, and was In charge of Tiff fany''s agent. It is said the crystals were so clear and fawless that they will be ground down into lenses for the big tele- scopes in the observatories. The car if all reports are true, contained the most valuable property ever brought down would run away up into a good sized fortune. The. agent was so careful that 1t be handled gently that he paid the pay. As the crystals were very plentiful where this lot came from the owners of the property have better thing than a dozen KlondikeS Tn sfpht
