598 MD^ING INDUSTEY. 



tramway, which drum is controlled by a brake. The car is capable of con- 

 taining about 1,000 pounds of ore. The details of construction, showing the 

 method of supporting the cables in such way that the cars may pass, the form 

 of the framework to which the car is attached, and the arrangement of the 

 sheaves cannot be very intelligibly explained without drawings, which are not 

 in the writer's possession. It is said to work satisfactorily. 



Coin. — The U. S. Coin lode has been developed by the same company. 

 It crops out a little higher up the hill and is opened further west than the Brown 

 mine. Its course is nearly due east and west, the dip being almost vertical. 

 The ore, in its mode of occurrence and general character, is like that of the 

 Terrible and Brown lodes in most respects, but is usually concentrated in a 

 narrow seam of rich mineral. Ruby silver is said to occur frequently. Small 

 lots of ore from this lode have yielded very high returns. 



Lilly and Roe. — The Lilly and the J. J. Roe, though different locations, 

 are thought to be on one and the same vein. This is still higher up the hill 

 than the last-named. Its course, where observed, is north 55° east, true, 

 dipping to the south at an angle of 80° from the horizon. This lode has also 

 produced rich ores, similar, in general character, to those just described. In 

 1868 two tons of selected ore yielded $400, coin, per ton. The lower grade 

 ore, treated at the amalgamation works in Georgetown, yielded about $150, 

 coin, per ton, for a lot of 44 tons. The developments on this lode have been 

 considerable as compared with other lodes in the neighborhood, but have 

 not yet reached great depth. When seen by the writer the deepest point 

 attained was not more than 100 feet. The vein had been stripped along the 

 surface but not drifted upon very extensively in depth. 



Sherman Mountain. — Sherman Mountain, as it is called by some, or 

 Republican Mountain, by others, is next east of Brown Mountain, from which 

 it is divided by a narrow gorge or ravine. This hiU. has also been exten- 

 sively prospected and many lodes have been opened, though only a few have 

 been developed to a depth exceeding 100 feet. They are generally of the 

 same type as those just described. Prominent among them are the Cashier, 

 Mendota, Snowdrift, Robert Emmet, Bush, Huntington, and others. The 

 first-named is thought to be an extension of the Terrible, though its identity 

 could not be established from observations made at the time these notes were
