HOFFMAN ON THE MINERALOGY OF NEVADA. ■ 741 



early yet to make any estimate of the future value of the discovery, but 

 it is certainly the most promising vein of coal yet discovered in the 

 State of Kevada, and I believe the first true coal found west of the 

 Eocky Mountains, or perhaps west of the Missouri Kiver, unless some 

 of the Utah coals belong to the coal-measures of Carboniferous age. . . . 

 About midway between White Pine and Pancake two or three mounds, 

 which are identical, both lithologically and paleontologically, with the 

 limestone of Treasure Hill, crop through the Quaternary formation of 

 the valley, and still further west are found dark bituminous shales 

 identical with those found along the east slope of Treasure Hill and 

 under the towns of Hamilton and Eberhardt. Some four miles still 

 further west, and belonging to a much higher geological horizon, we 

 find the coal formation." This gentleman further says that fossils have 

 been found — vegetable. A few Sigillaria have been collected on the 

 surfiice in the immediate vicinity. No analyses are given in the report, 

 and nothing can be said regarding the actual value of the discovery. 

 The coal above referred to is found in a vein of from five to six feet in 

 thickness, though distorted and broken, running north and south, '' and 

 dips quite steeply (40°) to the west. . . . Several experiments at 

 coking on a small scale have been tried, and have resulted satisfactorily." 



Mr. Eaymond says that during the year 1874 the mine was worked to 

 a depth of 480 feet, measured on the incline, the Eureka Consolidated 

 Company buying the coal at the rate of from $12 to $20 per ton on the 

 dump. 



The Momomoke and Antelope Eanges have since been examined, but, 

 as far as I have been able to learn, with but little success. 



At many of the smelting works, the reduction of silver ores was^ 

 accomplished by the use of charcoal. The scarcity of wood in some 

 regions has caused some uneasiness of late, and coal must either be 

 brought from outside sources at great expense or developed within the 

 State, if it can be discovered in sufficient quantity and of necessary 

 quality. 



APPENDIX B. 

 WATER. 



In giving the following list of springs, both mineral and thermal, the 

 qualitative results only are stated. In nearly all instances there was 

 more or less organic matter present — from local causes — so that at the 

 end of six or eight months, when the vessels were opened, the presence 

 of sulphureted and carbureted hydrogen gases proved that material 

 changes had been wrought, sufficiently at least that no analyses would 

 show what the sample was when collected. The mineral ingredients in 

 some were unimpaired, as they were comparatively the same as when 

 collected.
