sit is a placer. (Pampelly.) Nevada — Storey County, in the Comstock 

 lode, in filaments, and matted, hairy masses — " wire silver," usually 

 closely associated with silver j^lance and stephanite. At' the Burning 

 Moscow claim, (Ophir,) some largo masses of ore were taken out in eigh- 

 teen hundred and sixty-four, completely charged with the metal. Occurs 

 also at the Daney Mine with native gold and sulphuret of silver. Lander 

 County, in the veins about Austin, associated with the surface ores, such 

 as the chloride and bromide of silver, and green and blue carbonates of 

 copper. Idalw Territory, in large masses at the " Poor Man's lode," or 

 " Candle-box Mine," where it was said the lumps of silver were as largo 

 as candle boxes. That a great quantity of large masses of the metal 

 was taken out there is no doubt. It is common in the silver lodes of the 

 Owj'hee, and is u^sually very filamentous and finely divided and imbedded 

 in granular quartz. 



SILYER— (rc?^in-e< o/.) 



A single specimen was obtained by the author in eighteen hundred and 

 fifty-four, near Georgetown, in El Dorado County. It had been washed 

 out from the gold drift, and the parent vein has never been found. —

SMOKY QUARTZ. 



A large crystal about six inches in diameter, from Placer County, and 

 in the cabinet of Dr. White, Placerville. 



SPHERE. 



In small hair-brown crystals in the granite of the Sierra Nevada. 



STEPHANITE— (i?>7'«?e Sulphuret of Silver.) 



Yery fine crystals of stephanite were obtained from the Ophir and 

 Mexican Mines, Nevada, soon after they were opened. These crystals 

 were from half an inch to two inches in length, but were generally 

 impei-fectly formed. They greatly resemble the crystallizations of vitreous 

 copper from the Bristol Mine in Connecticut. A large collection of these 

 was made b}^ R. L. Ogden in eighteen hundred and fifty-nine and sixty, 

 and were noticed by the writer in the Mining Magazine. They arc now 

 more rare, but have been found in nearly all the principal claims upon 

 the Comstock lode. Some very good specimens were taken from the 

 Gould and Curry, and preserved in the cabinet by C. L. Strong in 

 eighteen hundred and sixt^^-four. They are frequently implanted among 

 quartz crystals in nests or geodes, and are covered with a hairy gi'owth 

 of wire silver. 



Crystals of silver ore from Silver Mountain District are probably this 

 species. 



STIBNITE. 



Tulare County, in a large vein near the Pass of San Am6dio. (Yide Rep. 

 Geol. Rec. Cal, pp. 292-3.) It occurs in large, solid masses, boulders of 

 wdiich are numerous in the beds of the arroyos leading from the vein. 

 In Nevada, at or near the Gem Mine, Dunglen ; at the Sheba Mine, in 

 beautiful needle-like crystals ; and at the De Soto and other mines in that 

 vicinity; in Russ District, Great Basin.
