  cated 
  by 
  broad 
  divisions 
  or 
  bands. 
  Of 
  these 
  bands, 
  there 
  were 
  

   three 
  : 
  the 
  Sandy 
  band, 
  the 
  Marly 
  band 
  and 
  the 
  Schistose 
  or 
  Metal- 
  

   hferous 
  band. 
  Ahhough 
  rough 
  in 
  outHnes, 
  this 
  map 
  even 
  yet 
  indi- 
  

   cates 
  in 
  a 
  general 
  way 
  the 
  character 
  of 
  the 
  rocks 
  of 
  the 
  Paris 
  basin. 
  

   His 
  work 
  on 
  this 
  and 
  several 
  other 
  maps 
  attracted 
  considerable 
  at- 
  

   tention 
  at 
  the 
  time 
  and 
  the 
  Academy 
  of 
  Science^ 
  stated 
  that 
  the 
  

   work 
  " 
  opens 
  up 
  a 
  new 
  field 
  for 
  geographers 
  and 
  naturalists, 
  and 
  

   forms, 
  so 
  to 
  speak, 
  a 
  link 
  between 
  two 
  sciences 
  'which 
  have 
  hitherto 
  

   been 
  regarded 
  as 
  entirely 
  independent 
  of 
  each 
  other." 
  Geikie^ 
  

   from 
  whom 
  these 
  facts 
  in 
  regard 
  to 
  Guettard's 
  work 
  have 
  been 
  

   taken, 
  says 
  that 
  this 
  " 
  gifted 
  Frenchman 
  " 
  may 
  be 
  called 
  the 
  father 
  

   of 
  all 
  the 
  national 
  geological 
  surveys 
  which 
  have 
  been 
  instituted 
  by 
  

   the 
  various 
  civilized 
  nations 
  of 
  the 
  old 
  and 
  the 
  new 
  worlds. 
  

  

  The 
  earliest 
  map 
  in 
  colors, 
  showing 
  the 
  aereal 
  distribution 
  of 
  

   rocks 
  was 
  that 
  of 
  J. 
  F. 
  W. 
  Charpentier, 
  of 
  the 
  Alining 
  School 
  at 
  

   Freiberg. 
  This 
  was 
  published 
  in 
  1778 
  at 
  Leipsig, 
  accompanying 
  his 
  

   Mineralogische 
  Gcographie 
  dcr 
  Chursachsischen 
  Lande] 
  and 
  the 
  

   distribution 
  of 
  gneiss, 
  schist, 
  loam, 
  granite, 
  limestone 
  etc. 
  was 
  indi- 
  

   cated 
  by 
  the 
  use 
  of 
  eight 
  tints.^ 
  

  

  Previous 
  to 
  the 
  year 
  1809 
  a 
  few^ 
  sketches 
  concerning 
  the 
  geology 
  

   of 
  the 
  United 
  States 
  had 
  appeared, 
  several 
  of 
  them 
  dealing 
  with 
  

   New 
  York 
  State. 
  The 
  first 
  definite 
  geological 
  mapping-^ 
  however, 
  

   was 
  the 
  work 
  of 
  AVilliam 
  McClure 
  who 
  has 
  been 
  termed 
  by 
  various 
  

   writers 
  " 
  The 
  father 
  of 
  American 
  Geology," 
  " 
  the 
  William 
  Smith 
  

   of 
  America," 
  etc. 
  This 
  map 
  was 
  a 
  hand-colored 
  geologic 
  chart 
  of 
  

   the 
  United 
  States 
  east 
  of 
  the 
  Mississippi, 
  and 
  was 
  published 
  with 
  

   his 
  paper 
  on 
  Observations 
  on 
  the 
  Geology 
  of 
  the 
  United 
  States, 
  in 
  

   the 
  Transactions 
  of 
  the 
  American 
  Philosophical 
  Society 
  of 
  Phila- 
  

   delphia. 
  Appearing 
  when 
  the 
  influence 
  of 
  Werner 
  and 
  his 
  classi- 
  

   fications 
  were 
  at 
  their 
  hight 
  and 
  Hutton's 
  more 
  rational 
  views 
  had 
  

   not 
  yet 
  been 
  accepted 
  by 
  the 
  majority, 
  it 
  strongly 
  favored 
  the 
  

   Wernerian 
  classification, 
  the 
  rocks 
  being 
  indicated 
  in 
  four 
  colors 
  

   called 
  Primitive, 
  Transition, 
  Secondary 
  or 
  Floetz, 
  and 
  xA.lluvial. 
  

  

  Although 
  crude 
  in 
  all 
  details 
  and 
  but 
  a 
  poor 
  substitute 
  for 
  the 
  

   later 
  maps 
  of 
  the 
  United 
  States, 
  when 
  one 
  recalls 
  that 
  the 
  science 
  

   was 
  still 
  in 
  its 
  infancy, 
  that 
  the 
  stratigraphic 
  studies 
  of 
  Murchison 
  

   and 
  others 
  were 
  still 
  in 
  the 
  future, 
  that 
  petrography 
  had 
  but 
  re- 
  

   cently 
  become 
  a 
  science, 
  he 
  can 
  not 
  but 
  marvel 
  at 
  the 
  results 
  

   achieved. 
  Then, 
  too, 
  McClure, 
  in 
  common 
  with 
  all 
  the
