384 QUICKSILVER DEPOSITS OF TBE PACIFIC SLOPE. 



mens of gravel from near Placerville, El Dorado County, containing gold 

 and rounded grains of pure cinnabar.^ This is probably at or near the 

 locality, three miles south of Shingle Springs, from which not only float cin- 

 nabar, but a ledge carrying this ore, was reported some years since.' 



Mr. Turner has visited this localit}', which is at Cinnabar City. The 

 deposit is a bedded vein in slates and quartzitic rocks. The cinnabar, 

 accompanied by pyrite, occupies interstitial spaces. A furnace was built 

 here and some quicksilver was produced. According to the county sur- 

 veyor, Mr. G. W. Kemble, cinnabar also occurs in place in the ravine of 

 Hastings Creek near its mouth and in the ravine of Clark's Creek about 

 one mile from its mouth, the two localities being presumably on the same 

 ledge. Hastings Creek empties into the south fork of the American River 

 from the north about three miles from Coloma. Clark's Creek flows from 

 the south into the same river about four miles northwest of Coloma. 



Gold amalgam is reported from British Columbia.' Mr. H. G. Hanks 

 has also analyzed arquerite (silver amalgam) from Vital Creek, British 

 Columbia, in latitude 53° north.* 



The only cinnabar deposit in British Columbia upon which any work 

 has been done i.s at Kicking Horse Pass (lat. 51'^ 20', long. 116° 30'), two 

 and a half miles east of Garden City. It is called the Ebenezer and is 

 described as a vein of calcite flecked with grains of cinnabar. The ore is 

 accompanied bv pyrite and contains traces of gold.'^ Dr. G. M. Dawson 

 reports that float cinnabar has been found in the gold washings on the 

 Fraser River, near Boston Bar. Rich specimens containing cinnabar and 

 native metal are said to liave come from the west side of the Fraser, near 

 Clinton, and the silver ores from Hope, on the Fraser, are stated to contain 

 mercury. A well defined lode containing rich cinnabar ore is also said to 

 occur on the Homathco River.*^ 



Mr. W. H. Dall informs me that in 1865 he saw a large piece of cin- 

 nabar in the Colonial Museum at Sitka, Alaska, which was said to have been
