THE MINERALS OF IDAHO 463 



tion below 1.53 and 7 index above 1.53. These properties identify 

 the mineral as ehalcanthite. 



SHOSHONE COUNTY 



Chalcanthite deposits from mine waters as small blue stalactites 

 in tunnels of the Evolution prospect near Osburn and the Wisconsin 

 prospect on the north side of the river west of Moon Gulch. In the 

 upper tunnel of the Lombardy prospect in Italian Gulch north of 

 Kellogg thin crusts of chalcanthite coat the walls of drifts and, 

 shelling off, accumulate in the soil of the floor. 



WASHINGTON COUNTY 



A body 40 feet square of high grade oxidized ore rich in copper 

 sulphate and gypsum occurred in the Silver Bell mine, Mineral 

 district. 70 



GOSLARITE (749) 



WHITE VITRIOL, ZINC VITRIOL 



Hydrous zinc sulphate, ZnO.S0 3 .7H 2 0. Orthorhombic, 



Zinc sulphate has never been definitely identified in the State, 

 although it probably occurs, but like other soluble sulphates it is 

 removed in solution. It may occur in the Coeur d'Alene district. 



SHOSHONE COUNTY 



In many places in the Coeur d' Alene district dry drifts have 



their rock coated with sparkling crusts of some soluble mineral or 



minerals, a part of which may be goslarite. Such sparkling crystals 



have been seen by the writer in the Greenhill- Cleveland mine and 



on the walls of the pumping stations of the Bunker Hill mine. Stout 



fibers occurring abundantly mixed with limonite from one of the 



upper tunnels of the Stemwinder mine at Wardner collected in 



1912 by John Goettge and Harry McDougall, of Wardner, were 



soluble in water with the astringent taste of goslarite but were not 



tested chemically. 



KALINITE (764) 



COMMON ALUM, POTASH ALUM 



Hydrous potassium aluminium sul- Isometric, 



phate, K 2 O.Al 2 3 .4S0 3 .24H 2 0. 



Although kalinite has never been definitely reported as such from 

 Idaho it is assumed that this mineral is meant by a reference to the 

 occurrence of alum. 



BANNOCK COUNTY 



Alum, presumably kalinite, is reported to occur in the sulphur 

 ore of the sulphur deposits near Soda Springs. 71 The mineral has
