Of the costs of operation the writer could learn but little. During the 

 White Pine excitement the mill was chiefly employed in working on ore from 

 that district, as the profit, at the prices then paid for milling, was greater than 

 could be derived from the ores of the company's mine. Only a small force 

 was at v/ork in this mine in the summer of 1869. 



The country south and east of White Pine, already partly prospected and 

 somewhat developed before the Treasure Hill discoveries attracted general 

 attention, has been more thoroughly examined, within the past year or two, 

 than ever before. Many new districts have been formed, and from some of 

 them the most encouraging accounts are being reported. The writer was 

 unable to visit any of them. Of some of the older districts descriptions may 

 be found in the reports of the United States Commissioner of Mining 

 Statistics. 



North and east from White Pine is the Egan district, lying on the old 

 overland road. The principal mine of this region was visited by Mr, S. F. 

 Emmons, whose notes concerning it are added here.
