TEEATMENT OF THE OOMSTOCK ORES. 247 



The following table shows some of the comparative results of a number 

 of different mills, all working on Savage ore at sundry times, between July 

 1, 1867, and March 1, 1868. The statement is furnished from the records 

 in the office of the Savage Mining Company. The careful manner in which 

 Mr. Bonner, the superintendent of this company, and his assistant officials 

 have collected and preserved in comprehensive form the various results of 

 milhng and mining experience is worthy of high praise and extended imita- 

 tion among others similarly engaged. The following table is but one exam- 

 ple among many which their records afford of valuable contributions to 

 useful or interesting statistical knowledge. 



The percentage of assay value obtained stated in the table, is based only 

 upon the amount taken from the customary process of treatment in pan and 

 separator, without taking into account anything subsequently produced from 

 the agitator or working of tailings, except where the contrary is specially 

 mentioned in the appended notes.
