  INDUSTRIAL 
  GEOLOGY 
  

  

  General 
  review. 
  The 
  work 
  in 
  industrial 
  geology 
  which 
  is 
  

   directed 
  chiefly 
  to 
  the 
  investigation 
  and 
  description 
  of 
  the 
  State's 
  

   mineral 
  resources 
  has 
  been 
  carried 
  forward 
  actively 
  during 
  the 
  past 
  

   year. 
  The 
  annual 
  summary 
  of 
  the 
  local 
  mining 
  field, 
  prepared 
  in 
  

   the 
  form 
  of 
  a 
  report 
  for 
  the 
  general 
  guidance 
  of 
  those 
  engaged 
  in 
  

   the 
  industry 
  or 
  otherwise 
  interested 
  in 
  its 
  current 
  progress, 
  has 
  been 
  

   continued, 
  and 
  the 
  latest 
  issue 
  brings 
  the 
  information 
  down 
  to 
  the 
  

   close 
  of 
  191 
  1. 
  Besides 
  complete 
  production 
  statistics, 
  the 
  report 
  

   contains 
  notes 
  and 
  short 
  articles 
  dealing 
  with 
  the 
  present 
  sources 
  

   of 
  supply 
  of 
  the 
  valuable 
  minerals 
  and 
  the 
  more 
  interesting 
  features 
  

   involved 
  in 
  their 
  exploitations. 
  In 
  the 
  year 
  191 
  1, 
  conditions 
  on 
  the 
  

   whole 
  were 
  rather 
  unfavorable 
  to 
  mining 
  and 
  quarry 
  operations; 
  

   very 
  few 
  branches 
  were 
  able 
  to 
  report 
  progress 
  in 
  terms 
  of 
  in- 
  

   creased 
  output. 
  The 
  aggregate 
  valuation 
  of 
  $31,573,111 
  for 
  the 
  

   crude 
  products 
  was 
  less 
  by 
  about 
  10 
  per 
  cent 
  than 
  the 
  total 
  returned 
  

   in 
  the 
  preceding 
  year. 
  The 
  iron 
  mining 
  industry 
  showed 
  the 
  full 
  

   effects 
  of 
  the 
  depression, 
  as 
  it 
  is 
  always 
  very 
  responsive 
  to 
  economic 
  

   changes. 
  The 
  clay-working 
  and 
  quarry 
  industries, 
  especially 
  the 
  

   departments 
  engaged 
  in 
  the 
  production 
  of 
  building 
  materials, 
  were 
  

   likewise 
  much 
  depressed. 
  The 
  setback 
  had 
  no 
  serious 
  consequences 
  

   so 
  far 
  as 
  concerns 
  the 
  permanent 
  welfare 
  of 
  the 
  industries, 
  and 
  it 
  

   is 
  expected 
  that 
  the 
  record 
  for 
  19 
  12 
  will 
  show 
  some 
  improvement, 
  

   if 
  not 
  material 
  gains, 
  in 
  many 
  branches. 
  

  

  Talc. 
  A 
  sketch 
  of 
  the 
  talc 
  deposits 
  of 
  St 
  Lawrence 
  county 
  and 
  

   the 
  present 
  status 
  of 
  their 
  industrial 
  development 
  has 
  been 
  pre- 
  

   pared 
  to 
  meet 
  the 
  public 
  inquiry 
  for 
  information 
  on 
  the 
  subject. 
  

   Some 
  interesting 
  developments 
  have 
  taken 
  place 
  during 
  the 
  last 
  

   year 
  or 
  two, 
  and 
  it 
  is 
  hoped 
  that 
  with 
  the 
  preparation 
  of 
  large-scale 
  

   topographic 
  maps, 
  a 
  work 
  now 
  in 
  progress, 
  the 
  opportunity 
  will 
  

   soon 
  be 
  forthcoming 
  for 
  a 
  comprehensive 
  account 
  of 
  the 
  geology 
  

   and 
  economic 
  features 
  of 
  the 
  district. 
  Since 
  commercial 
  operations 
  

   were 
  started, 
  a 
  little 
  over 
  thirty 
  years 
  ago, 
  the 
  mines 
  have 
  con- 
  

   tributed 
  nearly 
  a 
  million 
  and 
  a 
  half 
  tons, 
  all 
  of 
  which 
  required 
  

   mechanical 
  preparation 
  before 
  shipment 
  to 
  market. 
  There 
  is 
  no 
  

   other 
  district 
  in 
  this 
  country 
  where 
  the 
  mining 
  and 
  milling 
  of 
  talc 
  

   is 
  carried 
  on 
  on 
  so 
  large 
  a 
  scale. 
  The 
  occurrence 
  of 
  metallic 
  ores, 
  

   including 
  zinc 
  blende, 
  pyrite 
  and 
  hematite, 
  in 
  close 
  proximity 
  with
