﻿Report 
  on 
  the 
  New 
  York 
  State 
  Museum.

  The 
  later 
  collections 
  have 
  been 
  made 
  for 
  special 
  objects, 
  and 
  no 
  

   large 
  quantity 
  of 
  material 
  has 
  been 
  obtained. 
  

  

  In 
  this 
  connection 
  I 
  ought 
  to 
  state 
  that 
  from 
  certain 
  of 
  our 
  

   geologic 
  formations 
  within 
  the 
  State 
  of 
  New 
  York 
  there 
  are 
  

   almost 
  no 
  duplicates, 
  and 
  if 
  it 
  be 
  desirable 
  to 
  make 
  the 
  school 
  

   collections 
  complete 
  representations 
  of 
  the 
  geologic 
  formations 
  

   within 
  the 
  State 
  of 
  New 
  York, 
  it 
  will 
  be 
  necessary 
  to 
  make 
  

   collections 
  in 
  the 
  field, 
  especially 
  from 
  the 
  Hudson 
  river, 
  the 
  

   Niagara 
  and 
  Clinton 
  groups. 
  

  

  Of 
  the 
  two 
  last 
  formations 
  just 
  named, 
  we 
  are 
  obliged 
  to 
  give 
  

   in 
  these 
  collections 
  illustrative 
  specimens 
  from 
  the 
  collections 
  of 
  

   Ohio 
  and 
  of 
  Waldron, 
  Indiana. 
  The 
  specimens 
  of 
  fossils 
  from 
  these 
  

   localities 
  are 
  even 
  better 
  than 
  our 
  own, 
  but 
  they 
  will 
  not 
  give 
  to 
  the 
  

   student 
  the 
  true 
  idea 
  of 
  the 
  physical 
  characters 
  of 
  the 
  formation 
  

   and 
  the 
  condition 
  of 
  the 
  fossils 
  from 
  the 
  typical 
  localities 
  within 
  

   the 
  State 
  of 
  New 
  York. 
  Were 
  these 
  collections 
  to 
  be 
  used 
  for 
  

   students 
  making 
  critical 
  study 
  of 
  the 
  fossils 
  and 
  the 
  rock 
  

   formations 
  the 
  deficiency 
  would 
  be 
  a 
  serious 
  one, 
  but 
  where 
  such 
  

   studies 
  are 
  not 
  to 
  be 
  made, 
  and 
  if 
  not 
  considered 
  desirable 
  to 
  

   teach 
  the 
  physical 
  characters 
  of 
  the 
  formations, 
  the 
  collections 
  

   which 
  we 
  have 
  the 
  means 
  of 
  making 
  for 
  this 
  object 
  will 
  serve 
  

   the 
  purpose 
  very 
  well. 
  

  

  The 
  absence 
  of 
  specimens 
  of 
  fossils 
  from 
  the 
  formations 
  

   mentioned 
  is 
  due 
  to 
  the 
  fact 
  that 
  no 
  appropriations 
  of 
  money 
  for 
  

   the 
  collection 
  of 
  fossils 
  was 
  ever 
  made 
  till 
  after 
  the 
  completion 
  

   of 
  volume 
  II 
  of 
  the 
  Palaeontology 
  which 
  embraced 
  the 
  descrip- 
  

   tion 
  of 
  fossils 
  from 
  the 
  Potsdam 
  sandstone 
  to 
  the 
  Niagara 
  group 
  

   inclusive. 
  At 
  a 
  later 
  date 
  I 
  began 
  the 
  collecting 
  of 
  fossils 
  from 
  

   the 
  older 
  rocks, 
  in 
  order 
  to 
  provide 
  material 
  for 
  completing 
  the 
  

   school 
  sets, 
  and 
  we 
  have 
  a 
  fairly 
  large 
  amount 
  of 
  material 
  from 
  

   the 
  Trenton 
  and 
  lower 
  limestones. 
  This 
  work, 
  however, 
  was 
  

   suspended 
  owing 
  to 
  the 
  nonallowance 
  of 
  means 
  for 
  carrying 
  it 
  

   forward. 
  

  

  I 
  believe 
  I 
  have 
  in 
  a 
  previous 
  report 
  given 
  some 
  explanation 
  

   in 
  regard 
  to 
  the 
  absence 
  of 
  duplicate 
  specimens 
  from 
  certain 
  

   New 
  York 
  formations. 
  

  

  Yery 
  respectfully 
  submitted.

  HALL, 
  

  

  State 
  Geologist.
