382 MINING INDUSTEY. 



which is said to be better than either cog-gearing or belting. The V-shaped 

 friction-surface is cast in a rim that encircles the end of the barrel; the pinion, 

 with corresponding surface, is fixed in a sliding piUow-block, which may 

 easily be moved forward or backward, in order to be placed in or out of 

 contact with the rim, and so cause the barrel to revolve or to stand still. 



The mill, at the time referred to, was working 200 tons per month, of 

 which the average yield was $170, coin. 



Bullion Product of Austin Mines, — The bullion product of the coun- 

 try about Austin is not easily stated within close limits of accuracy. The 

 accounts of the banks and express office frequently include lots of bullion from 

 sources quite remote from Austin, such as Twin Eiver, Belmont, and, for- 

 merly. White Pine. 



In 1868 the shipment appears to have been as follows: 



From the Manhattan company $1, 152, 576 75 



J. A. Paxton & Co., bankers, shipping bullion derived from 



many sources, including $96,711 28 from White Pine. ... 1, 070, 727 16 

 National Bank 514, 000 00 



2,737,303 91 



During the first eight months of 1869 the shipment of bullion from 

 Austin, most of which was produced in the immediate vicinity, was between 

 $90,000 and $100,000 per month. 



Outlying Districts. — The Toyabe range, of which the Austin mining 

 region is the principal point of interest, has been explored for many miles along 

 its course, from north to south. Extending in the last-named direction some 

 40 or 50 miles from Austin, and situated chiefly on the eastern slope of the 

 range, there is a succession of mining districts, which, during the earlier days 

 of their history, were regarded as very important. Considerable sums of money 

 have been expended in their development, and several large and costly mills 

 were built for the working of their ores. The value of many of these mines 

 or districts was doubtless vastly overestimated, and the money spent upon them 

 was wasted. Others have been shown by steady development to be rich and 

 valuable mines, but few, if any, of these have been worked with profit, under 

 the disadvantages of high cost of labor and materials, and the necessity of
