In presenting this table of returns for 1881, it is but justice to say that while 

 extraordinary efforts have been made to secure accurate figures, it is not claimed 

 that they are in all cases absolutely reliable. Knowing the anxiety of the public 

 to be advised-concerning the yield of the mines for the past year, we give them 

 as received, but it is probable that a revised table will be prepared and published. 

 From the manner in which the returns have been received, no attempt has been 

 made to separate the metals. Therefore it will be understood that the totals 

 comprise gold, silver, copper and lead. 



PRODUCT FROM 1 85 9 TO 1882.
