  The 
  years 
  from 
  1887 
  to 
  1890 
  include 
  the 
  time 
  when 
  he 
  most 
  

   nearly 
  threw 
  off 
  the 
  limitations 
  of 
  ill 
  health. 
  In 
  the 
  summer 
  

   of 
  1887, 
  accompanied 
  by 
  his 
  wife 
  and 
  youngest 
  daughter, 
  he 
  

   revisited 
  the 
  Sandwich 
  Islands, 
  the 
  acquaintance 
  of 
  which 
  he 
  

   first 
  made 
  in 
  1840, 
  when 
  on 
  the 
  Exploring 
  Expedition. 
  This 
  

   was, 
  indeed, 
  the 
  first 
  long 
  journey 
  made 
  except 
  that 
  to 
  Europe 
  

   in 
  search 
  of 
  health 
  in 
  the 
  years 
  of 
  1859-60, 
  since 
  the 
  expedi- 
  

   tion 
  returned 
  in 
  1842. 
  He 
  was 
  led 
  to 
  make 
  this 
  journey* 
  

   because 
  of 
  the 
  interest 
  aroused 
  in 
  discussing 
  the 
  phenomena 
  

   connected 
  with 
  the 
  eruption 
  of 
  the 
  volcano 
  of 
  Kilauea 
  on 
  the 
  

   island 
  of 
  Hawaii. 
  The 
  journey 
  brought 
  the 
  keenest 
  pleasure, 
  

   not 
  only 
  that 
  due 
  to 
  revisiting 
  the 
  Sandwich 
  Islands 
  themselves 
  

   but 
  also 
  that 
  of 
  making 
  the 
  acquaintance 
  of 
  a 
  number 
  of 
  inter- 
  

   esting 
  places 
  in 
  the 
  western 
  United 
  States. 
  Although 
  travel 
  

   had 
  ordinarily 
  been 
  too 
  severe 
  a 
  tax 
  since 
  his 
  health 
  gave 
  out, 
  

   this 
  journey 
  of 
  ten 
  weeks 
  extending 
  over 
  ten 
  thousand 
  miles, 
  

   proved 
  of 
  profit, 
  and 
  every 
  incident 
  was 
  entered 
  into 
  with 
  the 
  

   enthusiasm 
  of 
  a 
  mind 
  which 
  years 
  could 
  not 
  make 
  old. 
  A 
  

   number 
  of 
  papers 
  upon 
  the 
  Hawaiian 
  volcanoes 
  were 
  the 
  result 
  

   of 
  this 
  summer's 
  outing, 
  and 
  in 
  the 
  winter 
  of 
  1889-90, 
  he 
  

   prepared 
  a 
  volume 
  on 
  Yolcanoes, 
  a 
  companion 
  to 
  that 
  on 
  

   Corals 
  and 
  Coral 
  Islands, 
  a 
  new 
  edition 
  of 
  which 
  was 
  issued 
  

   at 
  the 
  same 
  time. 
  The 
  prefaces 
  of 
  both 
  works 
  were 
  dated 
  on 
  

   his 
  seventy-eighth 
  birthday, 
  February 
  12, 
  1890. 
  

  

  In 
  the 
  summer 
  of 
  1889, 
  he 
  attended 
  the 
  meeting 
  of 
  the 
  

   American 
  Association 
  at 
  Toronto, 
  the 
  first 
  time 
  he 
  had 
  been 
  

   present 
  at 
  such 
  a 
  meeting 
  since 
  he 
  delivered 
  the 
  presidential 
  

   address 
  more 
  than 
  thirty 
  years 
  before. 
  

  

  With 
  the 
  autumn 
  of 
  1890 
  came 
  a 
  more 
  serious 
  illness 
  than 
  

   any 
  since 
  1859, 
  and 
  the 
  indications 
  seemed 
  very 
  alarming. 
  

   For 
  a 
  number 
  of 
  months 
  absolutely 
  no 
  work 
  was 
  done, 
  and 
  

   later 
  only 
  a 
  little 
  light 
  labor 
  by 
  means 
  of 
  dictation. 
  It 
  was 
  at 
  

   this 
  time 
  that 
  the 
  small 
  volume 
  on 
  the 
  New 
  Haven 
  region 
  

   entitled 
  " 
  The 
  Four 
  Rocks," 
  was 
  given 
  to 
  the 
  public. 
  This 
  

   disability 
  was 
  again 
  partially 
  thrown 
  off 
  — 
  -although 
  he 
  never 
  

   again 
  resumed 
  active 
  College 
  duty 
  — 
  and 
  the 
  work 
  on 
  the 
  fourth 
  

   edition 
  of 
  the 
  Manual 
  of 
  Geology, 
  then 
  far 
  advanced, 
  was 
  

   resumed 
  slowly 
  at 
  first 
  and 
  then 
  with 
  more 
  vigor 
  with 
  returning
