b  Personal  estimate. 
World's  production  ot  spelter,  571,705  metric  tons. 
It  will  be  noted  that  the  mining  districts  and  the  smelting  centers 
are  by  no  moans  identical.  Belgium  and  Holland  in  particular  have 
a  smelting  industry  much  larger  than  their  local  mining  interests.  In 
the  United  States  the  mining  industry,  the  smelting  industry,  and  the 
home  consumption  are  in  approximate  equilibrium.  In  1903,  35,188 
short  tons  of  ore  and  1,521  short  tons  of  spelter  were  exported.  The 
total  production  of  spelter  for  the  year  is  given  by  Mr.  Kirchhoff  as 
below :

In  the  above  total  are  included  3,302  tons  of  dross  spelter.  The 
small  amount  of  metal  produced  by  the  Indiana  furnaces  is  included 
in  that  credited  to  Illinois. 
The  zinc-oxide  production  for  the  year  is  estimated  at  62,962  tons. 
There  is  in  addition  a  small  amount  imported,  but  the  exports  of
