  by 
  a 
  glance 
  at 
  the 
  index, 
  those 
  between 
  1822 
  and 
  1834 
  being 
  small 
  

   black 
  and 
  white 
  etchings. 
  

  

  We 
  come 
  now 
  to 
  the 
  publication 
  of 
  the 
  first 
  geologic 
  map 
  of 
  

   New 
  York 
  State 
  as 
  a 
  unit. 
  This 
  was 
  Eaton's 
  map 
  published 
  with 
  his 
  

   "Textbook" 
  in 
  1830. 
  This 
  is 
  a 
  curiously 
  interesting 
  hand-colored 
  

   map 
  of 
  the 
  State. 
  On 
  it 
  he 
  divided 
  the 
  regular 
  deposits 
  accord- 
  

   ing 
  to 
  the 
  following 
  Wernerian 
  scheme: 
  five 
  " 
  classes 
  " 
  called 
  Prim- 
  

   itive, 
  Transition, 
  Lower 
  Secondary, 
  Upper 
  Secondary 
  and 
  Tertiary 
  

   were 
  distinguished 
  and 
  these 
  in 
  turn 
  were 
  each 
  divided 
  into 
  three 
  

   formations 
  called 
  " 
  Carboniferous," 
  " 
  Quartzose 
  " 
  and 
  " 
  Calcare- 
  

   ous." 
  The 
  colors 
  represented 
  on 
  the 
  map 
  are 
  six, 
  one 
  color, 
  slate, 
  

   representing 
  all 
  t]:e 
  V 
  Carboniferous 
  " 
  formations, 
  the 
  Roman 
  

   numerals 
  I, 
  II 
  and 
  III 
  representing 
  whether 
  they 
  belonged 
  to 
  the 
  

   "Primitive" 
  or 
  "Secondary 
  (Lower 
  or 
  Upper)." 
  Other 
  colors 
  

   represented 
  the 
  quartzose 
  and 
  calcareous 
  formations, 
  the 
  variegated 
  

   red 
  sandstone, 
  one 
  color 
  being 
  used 
  for 
  both 
  the 
  present 
  Medina 
  

   and 
  the 
  Triassic 
  red 
  sandstone, 
  or 
  as 
  he 
  says 
  " 
  sandstones 
  support- 
  

   ing 
  salt 
  springs 
  or 
  basalt," 
  the 
  " 
  lias 
  or 
  ferriferous 
  rocks 
  of 
  a 
  sub- 
  

   ordinate 
  series 
  " 
  roughly 
  corresponding 
  to 
  the 
  present 
  Salina 
  shales, 
  

   Basaltic 
  rocks 
  and 
  " 
  superficial 
  shell 
  marl 
  " 
  scattered 
  in 
  spots 
  over 
  

   the 
  southern 
  tier 
  of 
  counties. 
  

  

  Professor 
  Eaton 
  made 
  a 
  poor 
  attempt 
  at 
  mapping 
  the 
  Adiron- 
  

   dacks. 
  As 
  they 
  appear 
  on 
  his 
  map 
  they 
  consist 
  of 
  alternating 
  

   bands 
  of 
  Primitive 
  and 
  Seccxidary 
  Carboniferous 
  and 
  Calcareous 
  

   rocks. 
  He 
  notes 
  in 
  the 
  text 
  various 
  Adirondack 
  rocks 
  inost 
  of 
  

   which 
  are 
  now 
  known 
  to 
  be 
  igneous, 
  but 
  says, 
  " 
  we 
  infer 
  that 
  

   granite, 
  mica 
  slate, 
  bornblende 
  rock, 
  talcose 
  slate, 
  granular 
  quartz 
  

   and 
  granular 
  limestone 
  had 
  all 
  been 
  deposited 
  and 
  become 
  in- 
  

   durated 
  before 
  any 
  plants 
  or 
  animals 
  had 
  been 
  created." 
  

  

  In 
  the 
  early 
  thirties, 
  various 
  influences 
  were 
  brought 
  to 
  bear 
  

   upon 
  the 
  New 
  York 
  State 
  Legislature, 
  toward 
  the 
  establishment 
  

   of 
  a 
  museum 
  of 
  natural 
  history 
  and 
  a 
  geological 
  survey 
  of 
  the 
  

   State. 
  First 
  of 
  these 
  was 
  the 
  work 
  done 
  by 
  Professor 
  Eaton 
  from 
  

   1820 
  to 
  1830, 
  wdiich 
  has 
  already 
  been 
  noted. 
  This 
  work 
  was 
  car- 
  

   ried 
  on 
  under 
  the 
  patronage 
  of 
  Hon. 
  Stephen 
  \'an 
  Rensselaer. 
  

   In 
  1834 
  the 
  Albany 
  Institute^ 
  presented 
  to 
  the 
  Legislature 
  a 
  memo- 
  

   rial 
  asking 
  for 
  the 
  establishment 
  of 
  a 
  State 
  Museum, 
  and 
  in 
  1835 
  

   the 
  New 
  York 
  Lyceum 
  of 
  Natural 
  History 
  (The 
  American 
  Insti- 
  

   tute 
  of 
  the 
  City 
  of 
  New 
  York) 
  presented 
  a 
  similar 
  petition 
  or 
  

   memorial.-
