County. The variety, “electrum,” containing [from 3C> to 40 per ct. of 
silver, has been met with in octahedral crystals at Ward’s Mine in David- 
son county ; also, in Union county, at the Pewter Mine, and associated 
with galenite and zincblende at the Stewart and Lemmon Mines, and in 
the neighborhood ot Gold Hill. 
According to Dr. Asbury, very interesting specimens have been found 
at Silver Hill, when the mine was first opened, consisting ot specimens 
of several inches in length, one end of which was pure gold, while the 
other was pure silver. None of them have been preserved. 
2. Silver. 
This is on the whole a rare mineral in North Carolina. It has been 
obtained in considerable quantities at Silver Hill, in its native state, 
foliated and in plates in cerussite, also associated with argentite, galenite, 
zincblende, in small lumps, and arborescent and lilifirm masses; it has 
also been found in small plates and reticulated masses, associated with 
tetrahedrite and zincblende, at the McMakin Mine* in Cabarrus county; 
two specimens ot laminated silver have been observed by Dr. Asbury at 
the Asbury Mine in Gaston county ; it has also been found by Hon. C. J. 
Cowles, of the Charlotte Mint, associated with chalcocite, at Gap Creek 
Mine, Ashe county. 
3. Platinum. 
The occurrence ot grains of platinum among the sands of goldwash- 
ings of Rutherford and Burke counties, was first brought to notice by 
General Clingman, who sent half a dozen grains from a mine, near Jeanes- 
town, to Prof. C. U. Shepard. It has also been found on Brown Moun- 
tain, in Burke, according to the intormation received from Mr. E. Bissell. 
It is reported as having been found near Burnsville, Yancey county. 
4. Palladium. 
General Clingman sent a specimen to Prof. C. U. Shepard, which came 
probably from Burke or Rutherford comity, which the latter pronounced 
“ native palladium.” 
5. Copper. 
It has been found in small quantities in several mines, principally near
