cost of long transportation of the ore, involving an expense for that item 

 of not less than $4 per ton, and sometimes more. An additional disadvantage 

 is the liability to long-continued interruption in the work, owing to the im- 

 passable condition of the roads during bad weather, stopping the supply of 

 ore, and diminishing the earnings of the mill, while some of the expenses 

 must of necessity continue. Thus, during the months of January, February, 

 and March, 1868, no ore was received from the mine or crushed; and the 

 total loss of time by the stamps or crushing machinery, owing to this and 

 other causes, was 150 days during the whole year. The pans lost during the 

 same year 118 days. 



In the following year, the stamps lost 195 days, while the pans lost 180 

 days. 



The power is supplied by a 28-foot water-wheel, and an engine of 16- 

 inch cylinder. The capacity of the stream is unknown to the writer, and the 

 proportion of power furnished by the wheel is uncertain ; but as about five 

 cords of wood per day were consumed, on the days of actual running, the 

 engine must act an important and indispensable part in the operation of the 

 mill. 



The mill has sixteen stamps weighing each about 700 pounds, and twelve 

 Wheeler pans. The method of operation corresponds in its essential features 

 with the general description already 'given.
