ECONOMICAL GEOLOGY.

Taconic slates, at the Dobson mine, there is found an accumulation of 
yellow and yellowish brown zinc-blende mixed with lime. I have not, 
however, seen anything from there which looks encouraging. 
Galenite and zinc-blende is associated with the gold ores at Murphy, 
Cherokee county. Highly argentiferous galenite occurs at several locali- 
ties on Beech mountain, Watauga; argentiferous and auriferous galenite 
have been discovered at Flint Knob in Wilkes county, and I have seen 
specimens of it from Marshall, Madison county, Clayton, Johnston county, 
and Elkin Creek, Surry county, and also in several of the copper mines 
throughout the state, but I have no knowledge of any deposit of sufficient 
magnitude to be worked advantageously.” 
Tin. 
u No tin ore has been found in North Carolina as yet. Traces of this 
metal have been found in the tungstates of Cabarrus county, and 
in a micaceous slate in Gaston county, associated with garnet and col- 
umnar topaz (pycnite).” 
AKSENIC, ANTIMONY AND BISMUTH. 
j.‘‘Only a few ores of arsenic and antimony have been noticed in North 
■Carolina. Amongst these is very rare native antimony, of which a small 
piece was submitted to my examination by Dr. Hunter, of Cottage Home, 
Lincoln county. It has been found in a small vein in Burke county. 
An examination proved it to be quite pure. 
Both arsenic and antimony are found in combination with other metals ; 
arsenic at a few localities in Union and Gaston counties, in small quanti- 
ties, as arsenopyrite or mispickel, associated with gold ores; and botn 
arsenic and antimony in the highly argentiferous tetrahedrite of the Mc- 
Makin, and the tetrahedrite of the Ludowick mines in Cabarrus county. 
Bismuth has been observed as bismuthinite in minute particles asso- 
ciated with the gold and copper ores of the Earnhardt vein at Gold Hill, 
and by Dr. Asbury as bismuthite with gold ores at the Asbury mine in 
Gaston county ; also as bismite, or teroxide of bismuth, in the same mine, 
and in combination with copper, lead and sulphur at Col. White’s mine 
in Cabarrus county, probably as aikinite. The most interesting ores are 
the telluride of bismuth (tetradymite) and the tellurate of bismuth (tnon- 
tanite) — both found associated with gold ores in numerous localities — in 
Davidson, Cabarrus, Gaston, McDowell and Burke counties. The bis- 
muthic gold mentioned by Shepard as coming from Rutherford, is prob-
