  The 
  growth 
  of 
  the 
  Survey 
  is 
  strikingly 
  brought 
  out 
  

   by 
  the 
  figures 
  given 
  by 
  Dr. 
  Smith. 
  During 
  the 
  forty 
  years 
  of 
  

   its 
  existence 
  the 
  personnel 
  has 
  increased 
  from 
  39 
  to 
  967 
  and 
  the 
  

   total 
  annual 
  appropriation 
  from 
  $106,000 
  to 
  $1,437,745. 
  The 
  

   history 
  of 
  the 
  Survey 
  from 
  its 
  beginning 
  in 
  1880, 
  with 
  Clarence 
  

   King 
  as 
  Director, 
  is 
  a 
  subject 
  full 
  of 
  interest 
  and 
  one 
  that 
  merits 
  

   full 
  treatment 
  elsewhere; 
  those 
  who 
  have 
  had 
  the 
  privilege 
  of 
  

   following 
  its 
  development 
  may 
  well 
  marvel 
  at 
  the 
  amount 
  of 
  valu- 
  

   able 
  work 
  that 
  has 
  been 
  accomplished. 
  The 
  United 
  States 
  Geo- 
  

   logical 
  Survey 
  is 
  an 
  institution 
  in 
  which 
  the 
  country 
  as 
  a 
  whole 
  

   may 
  take 
  pride 
  as 
  well 
  as 
  each 
  one 
  of 
  the 
  many 
  men 
  who 
  have 
  

   had 
  a 
  place 
  in 
  its 
  army 
  of 
  workers. 
  

  

  The 
  year 
  covered 
  by 
  the 
  present 
  report 
  has 
  seen 
  the 
  readjust- 
  

   ment 
  from 
  special 
  war 
  activities 
  to 
  the 
  regular 
  program 
  of 
  scien- 
  

   tific 
  work. 
  It 
  is 
  hardly 
  necessary 
  to 
  add 
  that 
  the 
  record 
  of 
  

   service 
  in 
  the 
  Army 
  and 
  Navy 
  on 
  the 
  part 
  of 
  members 
  of 
  the 
  

   Survey 
  was 
  distinguished 
  in 
  many 
  different 
  lines, 
  personal 
  and 
  

   otherwise. 
  Looking 
  back 
  over 
  the 
  long 
  period 
  during 
  which 
  the 
  

   Survey 
  has 
  ex'sted. 
  the 
  gradual 
  change 
  from 
  strictly 
  scientific 
  

   work 
  to 
  that 
  of 
  an 
  economic 
  nature 
  is 
  more 
  and 
  more 
  conspicuous. 
  

   This 
  change 
  has 
  been 
  inevitable 
  and 
  when 
  the 
  results 
  are 
  taken 
  

   into 
  account 
  hardly 
  to 
  be 
  regretted. 
  It 
  is 
  lamentable, 
  however, 
  

   that 
  the 
  salaries 
  of 
  the 
  geologists 
  connected 
  with 
  the 
  Survey 
  and 
  

   engaged, 
  for 
  example, 
  in 
  the 
  search 
  for 
  oil 
  and 
  gas, 
  are 
  pitifully 
  

   small 
  as 
  compared 
  with 
  those 
  paid 
  by 
  outside 
  organizations. 
  It 
  

   is 
  stated 
  that 
  of 
  the 
  group 
  of 
  thirty 
  oil 
  geologists 
  of 
  ten 
  years' 
  

   experience 
  only 
  two 
  now 
  remain 
  with 
  the 
  Survey. 
  

  

  The 
  progress 
  made 
  in 
  mapping 
  the 
  country 
  and 
  in 
  investigat- 
  

   ing 
  its 
  water 
  power 
  possibilities 
  are 
  important 
  topics 
  dealt
