386 QUICKSILVER DEPOSITS OF THE PACIFIG SLOPE. 



product for tlie last quarter of 1886 was 87 flasks. A furnace was being 

 built.^ This is, I believe, the only case in which tieniannite has ever been 

 mined and reduced on a commercial scale. A body of low-grade cinna- 

 bar is said to have been found near this mine. I also learned from Mr. J. 

 E. Clayton, tlirough Mr. I). T. Da)^, that cinnabar is found in the Camp 

 Floyd district, near Lewiston, in the Oquirrh Range, about sixty miles south- 

 west of Salt Lake City. The oi-e is said to occur in bunches and seams in 

 calcareous shales of Carboniferous age and to be accompanied by heavy 

 spar. The deposits at this locality can be followed for a mile or more, but 

 the ore is of low grade and has not been worked. 



Cinnabar has been reported from New Mexico, but I have seen no 

 definite locality given and no particulars. j\[any years since, remarkable 

 specimens of ore containing cinnabar with gold, silver, and copper ores 

 were shown in San Francisco, which it \a as said came from Arizona.

 way.
