ROCKY BAR MINE, GRASS VALLEY, NEVADA COUNTY. 



The Rocky Bar Mining Company was organized and went into operation as a 

 gold mining company in the early part of 1852. The grounds belonging to this 

 company are situated on Massachusetts Hill and upon Gold Hill, in the town 

 above mentioned. 



Owing to the lateness of the season at which they commenced operations, and 

 the sudden advent of the rains when but a small part of their adits and shafts 

 were completed, they were obliged to relinquish the working on Massachusetts 

 Hill for the balance of the season, or until the rains should cease, their works not 

 being in condition to afford sufficient drainage. 



* The company, therefore, proceeded to purchase a group of claims on Gold Hill, 

 from which they commenced the extraction of ore, and its reduction by the ma 

 chinery which they had erected. The reduction continued until the month of 

 June, at which time the company settled up their affairs ; and it was found that, 

 notwithstanding the inordinate high price of labor and necessaries, that the com 

 pany had met the outlays, which amounted to $47,000. 



This was accomplished in the face of every obstacle which the times in which 

 they operated presented ; and those acquainted with those early days are best 

 capable of judging what men engaged in this branch of employment had, as a 

 resultant, to encounter. 



At the close of 1852 the condition of the workings on Massachusetts Hill were 

 as follows : 



An adit had been driven two hundred feet, mostly through soft material, at an 

 expense of ten dollars per foot, and another below it, of the same length, through 

 hard trap rock, at an expense of $8,000. 



In addition to the above, five shafts, averaging fifty-five feet in depth, were sunk, 

 at an expense of $500. On Gold Hill, two shafts of fifty feet each, at the same 

 cost as the above. 



From the first part of 1853 up to the latter part of 1854 but little work was 

 done upon the mine, from some dissatisfaction of the stockholders abroad. At 

 this period the resumption of operations took place under a new Director, who 

 has proceeded to erect a system of working similar to that proposed in 1853, to 

 free the mine from water, which was the only impediment to progress at the time 

 the operations were relinquished. The present Director has erected a fourteen 

 horse-power engine near the summit of the hill and near the lode, and by the use
