316 MINING INDUSTEY. 



One of its hotels is said to have cost $40,000. For the last few years the 

 town has been almost entirely deserted. A mill of ten stamps and four 

 reverberatory furnaces for roasting the ore was built long ago at the mouth of 

 the canon, but has lately been taken down and removed to Unionville, a por- 

 tion of its material being used in reconstructing Mr. Fall's mill. 



The next range of mountains occurring east of that in which Unionville 

 is situated contains several districts, some of which have been extensively 

 prospected, although not very persistently developed. The principal point 

 of operations has been in the neighborhood of Dun Glen, a small town or 

 mining camp seven miles from Mill City, and about 25 miles from Unionville. 

 The most notable mine in this locality is the Tallulah, working on two or 

 three veins, and producing ore that is reported as very rich. Other compa- 

 nies have also made developments that were regarded as very encouraging; 

 but mining operations, during the last two or three years, have not been very 

 actively prosecuted. In the summer of 1869 there were but few men at 

 work in this region, though, later in the year, a mill, situated at Dun Grlen 

 and belonging to a New York company, resumed work, and a more vigorous 

 development of the district was looked for. 



Gold Run. — The Gold Run District lies upon the east side of the Gol- 

 conda Mountains, the next range east of that last referred to. The center of 

 operations is about 12 miles from the Pacific railroad. Its point ot commu- 

 nication with that road — a station known as Golconda — is 341 miles from 

 Sacramento. This region was visited, in 1868, by Mr. Arnold Hague, from 

 whose notes the following brief statement is obtained. 



The principal mines appear to be located upon one vein, occurring in a 

 metamorphic, siliceous slate, which here forms the foot-hills of the mountain 

 range. The vein strikes due north and south, and is said to have been traced 

 for a distance of more than three miles, extending southerly from the Gol- 

 conda mine to the Jefferson mine, where it is apparently divided, one branch 

 striking southwest and the other southeast. The vein, in that part which is 

 most developed, dips to the west at an angle of 30° degrees from the hori- 

 zon. It is six or seven feet wide. At the time referred to the vein in the 

 Golconda mine had been explored to the depth of 50 feet, and drifted upon, 

 at that level, about 120 feet. So far as developed the vein appears to main-
