These  figures  do  not  include  an  uncertain  amount,  placed  at  10.000 
to  20,000  tons,  which  is  annually  produced  and  consumed  in  China 
Owing  to  various  speculative  influences  the  average  price  of  tin  if 
the  New  York  market  during  1904:  was  practically  28  cents  pel 
pound,  a  very  slight  decrease  from  the  price  in  1903.  On  comparing] 
the  world's  production  of  the  common  metals  it  appears  that  thj 
yearly  output  of  zinc  or  copper  is  over  5  times  that  of  tin,  that  <H 
lead  over  9  times,  and  that  of  pig  iron  about  450  times  as  great. 
The  United  States  consumed  in  1904:  about  43,120  tons  of  the  met«j 
or  over  40  per  cent  of  the  world's  production  for  that  year.     Of  thlJ 
amount  about  13  tons  were  actually  produced  by  this  country,  coining 
from  the  Ross  mine,  at  GafTney,  S.  C.     Ore  containing  about  25  ton: 
of  metal  Avas  mined  in  Alaska  in  1904.  , 
In  view  of  the  high  price  which  tin  commands  and  the  great  dis 
parity  between  domestic  supply  and  demand  it  is  surprising  that II I] 
little  search  for  the  metal  should  be  made  in  this  country.     In  order  I 
if  possible,  to  aid  in  the  discovery  either  of  new  localities  for  tin  or  j, 
in  the  United  States  or  of  larger  deposits  in  localities  already  known •  L 
there  is  given  in  this  paper  a  summary  of  those  places  in  the  Unitei  h 
States  where  tin  ore  is  known  to  have  been   found,  with  a  brie  L 
description  of  the  mode  of  occurrence  and  the  accompanying  mineral  L 
at  the  more  important  localities.     For  comparison  and   for   fulle 
information  on  the  subject,  the  same  data  have  been  given,  whereve  L 
obtainable,  for  all  the  foreign  localities  which  produce  tin.  h 
TIN   IN  THE  UNITED  STATES.  L

By  L.  C.  Graton.  i , 
Tin  has  been  found  in  many  places  in  both  the  eastern  and  wes 
ern  parts  of  the  United  States,  and  in  consequence  can  not   be  coi  p 
sidered  a  rare  metal  in  this  country.     As  indicated  by  the  productio  f 
stated  above,  however,  it  is  by  no  means  abundant.
