  Volcanic 
  Research 
  at 
  Kilauea 
  in 
  the 
  Summer 
  

   of 
  1911 
  • 
  by 
  Frank 
  A. 
  Perret. 
  With 
  a 
  Report 
  by 
  Dr. 
  

   Albert 
  Brtjn 
  on 
  the 
  Material 
  taken 
  directly 
  from 
  " 
  Old 
  

   Faithful." 
  

  

  To 
  readers 
  of 
  the 
  six 
  preceding 
  papers 
  of 
  the 
  present 
  series* 
  

   —devoted 
  specifically 
  to 
  a 
  discussion 
  of 
  the 
  various 
  Kilauean 
  

   phenomena, 
  products 
  and 
  formations 
  — 
  it 
  will 
  have 
  been 
  

   evident 
  that, 
  by 
  reason 
  of 
  the 
  necessary 
  concentration 
  upon 
  

   each 
  particular 
  subject, 
  no 
  detailed 
  reference 
  to 
  the 
  research 
  

   work, 
  itself, 
  could 
  therein 
  be 
  made. 
  This 
  must 
  be 
  the 
  writer's 
  

   excuse 
  for 
  venturing 
  upon 
  a 
  seventh 
  paper, 
  which, 
  free 
  from 
  

   such 
  restrictions, 
  may 
  be 
  devoted 
  to 
  a 
  brief 
  exposition 
  of 
  the 
  

   origin 
  and 
  aim 
  of 
  the 
  expedition, 
  of 
  some 
  of 
  the 
  research 
  work 
  

   accomplished 
  and, 
  finally, 
  of 
  data 
  secured 
  and 
  resulting 
  from 
  

   subsequent 
  investigation 
  of 
  original 
  material 
  collected. 
  

  

  The 
  expedition 
  — 
  and 
  with 
  it 
  the 
  initiation 
  of 
  regular 
  and 
  

   continuous 
  observations 
  at 
  Kilauea 
  — 
  was 
  due 
  to 
  the 
  initiative 
  of 
  

   Prof. 
  T. 
  A. 
  Jaggar, 
  Jr., 
  geologist 
  of 
  the 
  Massachusetts 
  Institute 
  

   of 
  Technology, 
  who, 
  during 
  a 
  previous 
  visit 
  to 
  Hawaii, 
  had 
  

   become 
  impressed 
  with 
  the 
  opportunity 
  which 
  Kilauea, 
  above 
  

   all 
  other 
  volcanoes, 
  offers 
  for 
  direct 
  research 
  work, 
  and 
  deter- 
  

   mined 
  to 
  organize, 
  if 
  possible, 
  a 
  demonstration 
  of 
  its 
  feasibility. 
  

   To 
  this 
  end, 
  negotiations 
  were 
  entered 
  upon 
  between 
  the 
  

   Institute 
  and 
  residents 
  of 
  the 
  islands, 
  a 
  promise 
  of 
  cooperation 
  

   by 
  the 
  Carnegie 
  Geophysical 
  Laboratory 
  w 
  T 
  as 
  obtained, 
  and 
  a 
  

   set 
  of 
  cables 
  and 
  electric 
  thermometers, 
  for 
  spanning 
  the 
  crater 
  

   and 
  for 
  immersion 
  in 
  the 
  liquid 
  lava, 
  were 
  prepared. 
  Never- 
  

   theless, 
  for 
  various 
  reasons, 
  years 
  passed 
  without 
  accomplish- 
  

   ment 
  and, 
  at 
  the 
  beginning 
  of 
  1911, 
  the 
  entire 
  project 
  stood 
  to 
  

   expire 
  of 
  inanition. 
  

  

  At 
  this 
  stage 
  Prof. 
  Jaggar, 
  finding 
  himself 
  unable 
  to 
  assume 
  

   the 
  charge, 
  made 
  a 
  personal 
  appeal 
  to 
  the 
  writer 
  to 
  head 
  the 
  

   expedition 
  to 
  Kilauea 
  in 
  the 
  hope 
  of 
  making 
  a 
  demonstration 
  

   of 
  such 
  practical 
  utility 
  as 
  should 
  result 
  in 
  the 
  establishment 
  

   of 
  a 
  permanent 
  institution 
  on 
  the 
  spot, 
  and 
  promising 
  to 
  take 
  

   up 
  the 
  work, 
  himself, 
  at 
  a 
  later 
  date. 
  Although 
  very 
  loath 
  to 
  

   interrupt, 
  even 
  temporarily, 
  his 
  work 
  in 
  Italy, 
  f 
  the 
  writer 
  con- 
  

   sidered 
  the 
  foundation 
  of 
  such 
  a 
  work 
  in 
  his 
  own 
  country 
  of 
  

   foremost 
  importance, 
  and 
  it 
  was 
  thus 
  that, 
  in 
  company 
  with 
  Dr. 
  

   E. 
  S. 
  Shepherd, 
  of 
  the 
  Carnegie 
  Laboratory, 
  he 
  arrived 
  at 
  the 
  

   islands 
  in 
  June 
  and 
  commenced 
  those 
  observations 
  and 
  studies

  After 
  having 
  lived 
  through 
  the 
  Etna 
  eruption 
  of 
  1910, 
  all 
  the 
  phases 
  of 
  

   which 
  were 
  observed 
  and 
  photographed, 
  the 
  still 
  more 
  important 
  outbreak 
  

   of 
  1911 
  was 
  thus 
  missed, 
  leaving 
  a 
  gap 
  which 
  can 
  never 
  be 
  filled.
