The cost of the above labor is $3 50 to ^4 per day, excepting that of the 

 foremen, engineers, and mechanics, who receive more. The costs of working, 

 per ton, are indicated by the following statement, which expresses the average 

 for six months, from June to November, 1868. It is hardly necessary to 

 observe that the costs will vary considerably, increasing very much if the 

 quantity of ore worked be diminished, since a certain portion of the current 

 expense must remain the same, whether the number of tons treated be great 

 or small. Thus in March, 1868, when 278 tons of ore were worked, the cost 

 per ton was $47 84. In the following month, working 462 tons, the cost per 

 ton was $41 45. From June to November, 1868, the quantity worked was 

 3,005 tons, or about 500 tons per month. The details of cost were as follows: 



For labor ^13 99

For quicksilver 1 09
