﻿FOURTH 
  REPORT 
  OF 
  THE 
  DIRECTOR 
  ±907 
  9 
  

  

  or 
  Washington 
  avenue 
  structure 
  has 
  resulted 
  in 
  an 
  apparently 
  very 
  

   advantageous 
  division 
  of 
  the 
  museum 
  floor 
  into 
  two 
  levels. 
  Thus 
  

   from 
  the 
  main 
  level 
  described 
  one 
  rises 
  by 
  short 
  flights 
  of 
  steps 
  

   5 
  feet 
  to 
  a 
  higher 
  platform 
  running 
  the 
  entire 
  length 
  of 
  the 
  build- 
  

   ing 
  on 
  the 
  inner 
  side 
  save 
  where 
  the 
  space 
  is 
  divided 
  by 
  the 
  dome 
  

   and 
  the 
  corridors 
  into 
  the 
  northern 
  wing. 
  This 
  subdivision 
  affords 
  

   two 
  long 
  and 
  somewhat 
  narrow 
  but 
  not 
  constrained 
  chambers, 
  one 
  

   covering 
  about 
  11,000 
  square 
  feet, 
  the 
  other 
  5760 
  square 
  feet. 
  

   These 
  rooms 
  have 
  excellent 
  possibilities 
  for 
  the 
  display 
  of 
  the 
  ex- 
  

   tensive 
  collections 
  of 
  the 
  relics 
  of 
  Iroquois 
  and 
  other 
  Indian 
  cul- 
  

   tures 
  on 
  one 
  side, 
  and 
  for 
  the 
  botanical 
  collections 
  on 
  the 
  other. 
  

   The 
  space 
  thus 
  available 
  for 
  exhibition 
  purposes 
  is 
  

  

  Hall 
  of 
  Geology 
  30

  All 
  this 
  exhibition 
  space 
  is 
  lighted 
  entirely 
  from 
  above; 
  side 
  light 
  

   is 
  wholly 
  excluded. 
  It 
  is 
  recognized 
  that 
  this 
  mode 
  of 
  illumination 
  

   will 
  present 
  its 
  own 
  problems 
  in 
  the 
  effective 
  disposition 
  of 
  the 
  

   exhibits 
  and 
  may 
  call 
  for 
  special 
  construction 
  or 
  adaptations 
  in 
  the 
  

   form 
  of 
  the 
  cases 
  in 
  order 
  to 
  avoid 
  puzzling 
  or 
  troublesome 
  re- 
  

   flections, 
  but 
  it 
  may 
  prove 
  to 
  have 
  especial 
  advantages 
  in 
  flooding 
  

   the 
  whole 
  chambers 
  with 
  light 
  from 
  one 
  direction 
  without 
  the 
  inter- 
  

   ruption 
  or 
  isolation 
  that 
  comes 
  from 
  light 
  entering 
  separate 
  

   apertures, 
  like 
  a 
  series 
  of 
  windows. 
  

  

  The 
  construction 
  which 
  necessitates 
  the 
  elevation 
  of 
  the 
  inner 
  

   portion 
  of 
  the 
  main 
  floor 
  also 
  makes 
  provision 
  for 
  a 
  lower 
  level 
  

   on 
  this 
  inner 
  side 
  of 
  the 
  museum 
  apartments. 
  By 
  a 
  descent 
  of 
  7 
  

   feet 
  the 
  lower 
  level 
  is 
  reached 
  and 
  here, 
  on 
  either 
  side 
  of 
  the 
  main 
  

   corridor 
  to 
  the 
  wing, 
  are 
  rooms 
  for 
  the 
  offices 
  of 
  the 
  scientific 
  

   and 
  clerical 
  staff 
  adequately 
  equipped 
  with 
  files, 
  storage 
  and 
  labora- 
  

   tories. 
  This 
  lower 
  floor 
  turns 
  the 
  corner 
  at 
  each 
  angle 
  with 
  the 
  

   wing 
  and 
  runs 
  beneath 
  the 
  offices 
  of 
  the 
  Archeologist 
  and 
  Zoologist 
  

   on 
  the 
  level 
  above, 
  providing 
  room 
  for 
  an 
  Insectory 
  on 
  one 
  side 
  

   and 
  Artists 
  rooms 
  with 
  north 
  light 
  on 
  the 
  other. 
  This 
  entire 
  series 
  

   of 
  offices 
  is 
  supplied 
  with 
  lateral 
  light 
  and 
  the 
  suites 
  have 
  their 
  

   own 
  private 
  corridors. 
  The 
  surface 
  area 
  of 
  these 
  offices 
  is 
  about 
  

   19,000 
  square 
  feet. 
  The 
  total 
  available 
  space 
  for 
  all 
  museum 
  pur- 
  

   poses 
  is 
  practically 
  80,000 
  square 
  feet.
