The quicksilver resources of California . nace, having its own heating furnace. The Anderson Prospects.—Mayacmas District. In Sees. 25 and35, T. II N., R. 8 W. Owners, the Anderson family, AndersonSprings, Lake County. On the ridge between Bear Creek andthe south fork of the Putah, in section 35, about half a milesouth of Anderson Springs, a seam of good cinnabar ore hasbeen to some extent opened up in a very much decomposedsandstone. About one quarter of a mile southeast of Ander-son Springs, in Sec. 25, T. 11 N., R. 8 W., at an elevation of 300feet above the springs, the formation is strongly saturated withsulphur, which has thoroughly decomposed the country rock,wherefrom its local name of Sulphur Bank. The upper partconsists of thin, flat beds of quartzose rocks interbedded withclay seams (possibly a series of chert beds, like the ledge mat-ter of the Great Western, but too decomposed to be absolutelyclassified). The quartzose rock carries on its fracture facescinnabar; when broken it proves to contain a great amount of. LAKE COUNTY. 49 iron sulphides. Its structure would indicate that the twometallic sulphides were not deposited simultaneously. [See16th Ann. Rep. U. S. G. S., Part II, page 448, 3d line from top.]The softer decomposed clayey material does not contain anycinnabar; this material was probably decomposed by the actionof the waters highlj^ charged with sulphur on the less compactseams. This sulphur deposition must be of a different periodfrom that of the sulphides. Below these beds lies thoroughlydecomposed sandstone, having a nearly vertical bedding,wherein lies a 2-foot seam of quartzose material, similar to themore compact part of above described beds, standing parallelto the dip of the inclosing sandstone and carrjdng some cinna-bar. All the water at this Sulphur Bank is cold, while aquarter of a mile distant are the hot sulphur springs and blow-holes, from which hot sulphur vapors emanate, without anjformation of cinnabar ore.
