COPPER. 
THE  COPPER  MINES  OF  THE  UNITED  STATES  IN    1905. 
By  Walter  Harvey  Weed. 
INTRODUCTION. 
Copper  mining  in  the  United  States  has  had  a  marvelously  rapid  development  in  the 
last  ten  years,  showing  an  increase  of  150  per  cent  in  that  time.  The  production  for  1905 
broke  all  previous  records  and  brought  higher  prices  than  at  any  time  for  ten  years  past. 
The  greatest  increase  in  production  was  in  Arizona,  and  the  greatest  individual  increase 
that  of  the  Copper  Queen  mine  at  Bisbee,  Ariz.  The  following  table  shows  the  production 
and  relative  rank  of  the  different  producing  States,  the  figures  for  1904  being  those  prepared 
and  published  by  the  Geological  Surveys  while  those  for  1905  are  compiled  from  estimates 
by  various  trustworthy  authorities. b
