   these 
  consists 
  of 
  eight 
  sections,

  Another

  The 
  numismatic 
  

   collections 
  relative 
  to 
  the 
  World 
  War 
  have 
  been 
  increased 
  by 
  a 
  

   number 
  of 
  examples 
  of 
  the 
  medals 
  and 
  decorations 
  issued 
  in 
  the 
  

   United 
  States 
  and 
  European 
  countries 
  during 
  the 
  war. 
  

  

  The 
  original 
  historical 
  collections 
  have 
  been 
  increased 
  by 
  a 
  sword 
  

   carried 
  during 
  the 
  War 
  of 
  the 
  Revolution 
  by 
  General 
  Washington, 
  a 
  

   cane 
  bequeathed 
  to 
  him 
  by 
  Benjamin 
  Franklin, 
  and 
  a 
  sword 
  owned 
  

   by 
  Gen. 
  Andrew 
  Jackson. 
  These 
  three 
  objects 
  were 
  transferred 
  to 
  

   the 
  Museum 
  from 
  the 
  Department 
  of 
  State 
  by 
  joint 
  resolution 
  of 
  

   Congress 
  approved 
  February 
  28, 
  1922. 
  From 
  the 
  same 
  department 
  

   by 
  transfer 
  was 
  received 
  the 
  small 
  writing 
  desk 
  used 
  by 
  Thomas 
  

   Jefferson 
  when 
  he 
  drafted 
  the 
  Declaration 
  of 
  Independence 
  in 
  Phil- 
  

   adelphia 
  in 
  1776, 
  which 
  bears 
  a 
  memorandum 
  in 
  his 
  own 
  hand 
  at- 
  

   testing 
  to 
  its 
  history. 
  A 
  single 
  addition 
  was 
  made 
  during 
  the 
  year 
  

   to 
  the 
  collection 
  of 
  costumes 
  worn 
  by 
  the 
  mistresses 
  of 
  the 
  White 
  

   House. 
  This 
  was 
  the 
  dress 
  worn 
  by 
  Mrs. 
  Andrew 
  Jackson, 
  jr., 
  on 
  

   the 
  occasion 
  of 
  a 
  reception 
  given 
  at 
  the 
  White 
  House 
  in 
  her 
  honor 
  

   in 
  1831, 
  and 
  lent 
  to 
  the 
  Museum 
  by 
  Mrs. 
  Rachel 
  Jackson 
  Lawrence, 
  

   of 
  the 
  Hermitage 
  Association. 
  

  

  Work

  the 
  collections. 
  — 
  The 
  care 
  and 
  preservation 
  of 
  the 
  collec- 
  

   tions 
  require 
  a 
  large 
  proportion 
  of 
  the 
  energies 
  and 
  time 
  of 
  the 
  

   scientific 
  staff 
  and 
  present 
  many 
  difficulties 
  to 
  be 
  surmounted. 
  In 
  

   ethnology, 
  the 
  installation 
  of 
  the 
  Herbert 
  Ward 
  collection 
  led 
  to 
  a 
  

   recasting 
  of 
  the 
  African 
  collection 
  generally. 
  The 
  conditions 
  ham- 
  

   pering 
  the 
  development 
  of 
  the 
  biological 
  exhibition 
  since 
  the 
  later 
  

   years 
  of 
  the 
  World 
  War 
  have 
  continued, 
  making 
  it 
  impossible 
  to 
  

   do 
  more 
  than 
  remedy 
  special 
  defects 
  as 
  opportunity 
  presented. 
  A 
  

   general 
  overhauling 
  of 
  the 
  unmounted 
  larger 
  cetacean 
  material 
  has 
  

   placed 
  this 
  series 
  in 
  a 
  condition 
  to 
  be 
  used 
  for 
  the 
  first 
  time 
  in 
  many 
  

   years. 
  Commendable 
  progress 
  is 
  reported 
  in 
  the 
  care 
  of 
  the 
  geologi- 
  

   cal 
  collections, 
  though 
  comparatively 
  few 
  new 
  exhibits 
  were 
  in- 
  

   stalled.
