 mill was producing bullion, at the time of the writer's visit, that was from 

 tWo to tVo'o in fineness. 



The average cost of milling has been indicated in the statements already 

 given. The expense of treating 8,646 tons by the Consolidated Chloride 

 Flat Company was $14 60 per ton. This includes hauling, an item amount- 

 ing in this case to $4 60 per ton. The figures above given are the average of 

 all the ore treated up to February 1, 1870, and the costs in the latter part of 

 the included period were probably little less than the average of the whole, as 

 some items of expense have since been reduced. Moreover, the company had 

 between 200 and 300 tons of their ore worked in custom mills, at high prices, 

 which would slightly increase the average of the whole. 



In the month of August, 1869, the cost at the Manhattan mill was $12 34 

 per ton. The items composing this cost were as follows : 



Labor $3, 414 25 or, per ton, $3 10 



Supplies and materials 6, 208 45 or, per ton, 4 74 



Hauling 4, 950 00 or, per ton, 4 50 



1,100 tons, total 13, 572 70 12 34 



Allowing $4 50 for hauling, this sum is reduced to very nearly the same 

 as that shown to be the cost of milling at Washoe in some steam mills. 

 Labor is rather higher than at Washoe, and in the Manhattan mill, from which 

 these figures are obtained, more men are required in handling rock than are 

 usually employed at the Washoe mills. This is due to the want of a rock- 

 breaking machine, a suitable dump for the ore, and convenient arrangements 

 for fuel. Thus, the men employed were : 5 rock-breakers, 3 feeders, 3 amal- 

 gamators, 2 retort men, 3 wood-wheelers and passers, 2 firemen, 2 engine 

 drivers, 1 carpenter, 1 watchman, 1 foreman ; in all 23. 



The price of this labor is from $4 to $6 per day. The company own a 

 boarding-house and board their men. In the Eberhardt mill, where the men 

 are paid without board, the prices were as follows :
