The  production  of  petroleum  is  rapidly  increasing, ­
  in  1912  over  17,000,000  barrels  being ­
  the  output  from  the  wells.
Mexico  has  been  dependent  upon  Europe
and  the  United  States  for  her  coal  supply,  her
yearly  requirements  being  about  5,000,000  tons
of  which  she  produced  from  local  mines  almost ­
  1,000,000  tons.  There  are,  however,
enormous  deposits  of  this  commodity  and  under ­
  proper  development  Mexico  could  supply ­
  her  own  needs  in  this  line  as  well  as  become ­
  an  exporter.
The  local  industries  comprise  paper  mills,
cotton-mills,  cigarette  factories,  woolen-mills,
breweries,  sugar  refineries,  shoe,  furniture  and
match  factories.  They  produce  only  sufficient ­
  for  home  consumption.
Mexico  exported  goods  to  the  value  of
$150,202,808  in  1913,  while  during  the  same
period  her  imports  reached  the  sum  of  $97,-886,169,
  the  United  States  buying  and  selling
the  greater  portion  thereof.
