  began

  but 
  are 
  of 
  little 
  

   importance. 
  

  

  In 
  1865 
  there 
  was 
  published 
  by 
  the 
  Canadian 
  Geological 
  Survey 
  

   in 
  its 
  report 
  of 
  progress 
  for 
  1863, 
  a 
  Geologic 
  Map 
  of 
  Canada 
  and 
  

   the 
  Northern 
  Portion 
  of 
  the 
  United 
  States. 
  The 
  Canadian 
  por- 
  

   tion 
  of 
  this 
  map 
  was 
  prepared 
  by 
  Sir 
  W. 
  E. 
  Logan 
  while 
  the 
  

   United 
  States 
  portion 
  was 
  compiled 
  under 
  the 
  authority 
  of 
  

   Prof. 
  James 
  Hall. 
  It 
  is 
  of 
  interest. 
  in 
  connection 
  with 
  this 
  paper 
  

   because 
  of 
  the 
  fact 
  that 
  the 
  New 
  York 
  State 
  geology 
  indicated 
  

   upon 
  it 
  is 
  the 
  first 
  authoritative 
  revision 
  of 
  the 
  1842 
  map. 
  The 
  

   map 
  is 
  on 
  a 
  scale 
  of 
  125 
  miles 
  to 
  the 
  inch 
  and 
  is 
  very 
  well 
  colored. 
  

   It 
  was 
  in 
  reality 
  a 
  reduction 
  from 
  a 
  much 
  larger 
  map 
  on 
  a 
  scale 
  of 
  

   25 
  miles 
  to 
  the 
  inch 
  which 
  although 
  already 
  engraved 
  in 
  1863 
  was 
  

   not 
  published 
  till 
  1867. 
  This 
  larger 
  map 
  was 
  published 
  separately 
  

   and 
  not 
  widely 
  distributed. 
  It 
  is 
  said 
  that 
  but 
  three 
  copies 
  were 
  

   sent 
  to 
  the 
  United 
  States. 
  

  

  Up 
  to 
  this 
  time 
  colorations 
  of 
  maps 
  in 
  this 
  country 
  had 
  been 
  

   done 
  by 
  hand, 
  a 
  tedious 
  and 
  often 
  unsatisfactory 
  process. 
  In 
  

   European 
  countries, 
  schemes 
  for 
  color 
  printing 
  had 
  been 
  devised 
  

   and 
  successfully 
  carried 
  out, 
  as 
  early 
  as 
  1843. 
  In 
  America, 
  how- 
  

   ever, 
  the 
  chromolithographic 
  methods 
  supplanted 
  but 
  slowly 
  the 
  

   hand 
  coloration 
  and 
  although 
  the 
  first 
  map 
  printed 
  in 
  color 
  ap- 
  

   peared 
  in 
  1853 
  in 
  Massachusetts, 
  no 
  such 
  work 
  was 
  carried 
  on 
  

   in 
  New 
  York 
  State 
  till 
  1875. 
  The 
  first 
  map 
  with 
  printed 
  colors 
  in 
  

   the 
  State 
  appears 
  to 
  have 
  been 
  the 
  map 
  of 
  New 
  York 
  State 
  and 
  

   the 
  Eastern 
  States 
  by. 
  Hall 
  appearing 
  in 
  the 
  Museum 
  reports. 
  

  

  The 
  early 
  Museum 
  reports, 
  the 
  first 
  of 
  which 
  appeared 
  in 
  1848, 
  

   contained 
  but 
  few 
  maps 
  previous 
  to 
  1884 
  and 
  the 
  maps 
  of 
  the 
  

   period 
  1875 
  to 
  1885 
  were 
  published 
  mainly 
  by 
  the 
  American 
  Jour' 
  

   nal 
  of 
  Science 
  and 
  other 
  private 
  publications, 
  by 
  James 
  D. 
  Dana 
  

   and 
  others, 
  and 
  dealt 
  with 
  eastern 
  and 
  southeastern 
  New 
  York. 
  

  

  The 
  maps 
  appearing 
  in 
  the 
  years 
  1885 
  and 
  1886 
  dealt 
  also 
  with 
  

   eastern 
  New 
  York 
  with 
  the 
  exception 
  of 
  a 
  map 
  of 
  Ontario 
  county 
  

   by 
  John 
  M. 
  Clarke, 
  and 
  several 
  maps 
  dealing 
  with 
  the 
  oil 
  region 
  

   of 
  Allegany 
  county 
  were 
  the 
  first 
  economic 
  maps 
  to 
  be 
  published. 
  

  

  In 
  the 
  nineties 
  the 
  most 
  notable 
  feature 
  was 
  the 
  earnest 
  endeavor 
  

   made 
  to 
  work 
  out 
  the- 
  relation 
  in 
  the 
  Adirondack 
  crystalline 
  area. 
  

   This 
  work 
  was 
  commenced 
  in 
  1895 
  ^Y 
  Kemp 
  and 
  a 
  number 
  of 
  

   maps 
  appear 
  in 
  that 
  decade 
  by 
  Gushing, 
  Kemp 
  and 
  others.
