  strength. 
  From 
  this 
  time, 
  however, 
  till 
  the 
  end 
  he 
  seldom 
  

   exceeded 
  a 
  limit 
  of 
  three 
  hours 
  labor 
  each 
  day. 
  

  

  In 
  February, 
  1893, 
  the 
  printers 
  began 
  their 
  work 
  on 
  the 
  

   volume 
  mentioned 
  and 
  it 
  was 
  just 
  two 
  years 
  before 
  the 
  last 
  

   proof 
  had 
  been 
  read 
  and 
  the 
  volume 
  was 
  complete. 
  To 
  him- 
  

   self 
  and 
  still 
  more 
  to 
  those 
  about 
  him 
  it 
  seemed 
  many 
  times 
  as 
  

   if 
  the 
  completion 
  of 
  this 
  great 
  work 
  would 
  have 
  to 
  be 
  left 
  to 
  

   others, 
  but 
  with 
  the 
  self-control 
  born 
  of 
  a 
  strong 
  will 
  and 
  long 
  

   experience, 
  and 
  with 
  the 
  never 
  failing 
  watchful 
  care 
  of 
  his 
  

   life-long 
  companion 
  — 
  without 
  which 
  his 
  labors 
  could 
  never 
  

   have 
  been 
  so 
  productive 
  nor 
  have 
  been 
  continued 
  so 
  long— 
  he 
  

   worked 
  on 
  slowly, 
  doing 
  each 
  day 
  only 
  what 
  he 
  had 
  strength 
  

   for, 
  and, 
  finally, 
  the 
  labor 
  was 
  accomplished. 
  The 
  completion 
  

   of 
  this 
  work, 
  which 
  was 
  rewritten 
  and 
  rearranged 
  from 
  begin- 
  

   ning 
  to 
  end, 
  involving 
  a 
  critical 
  consideration 
  of 
  the 
  many 
  

   new 
  facts 
  and 
  theories 
  of 
  the 
  science, 
  will 
  be 
  granted 
  to 
  have 
  

   been 
  a 
  remarkable 
  performance 
  for 
  a 
  man 
  of 
  eighty-two. 
  He 
  

   finished 
  it 
  in 
  February, 
  1895, 
  and 
  a 
  month 
  later 
  he 
  had 
  com- 
  

   pleted 
  the 
  manuscript 
  of 
  a 
  new 
  edition 
  of 
  his 
  Geological 
  Story 
  

   and 
  then 
  commenced 
  work 
  on 
  that 
  of 
  the 
  Text 
  Book. 
  

  

  On 
  Saturday, 
  April 
  13th, 
  he 
  took 
  his 
  usual 
  excursion 
  to 
  the 
  

   Post 
  Office, 
  and 
  through 
  the 
  day 
  was 
  as 
  bright 
  and 
  vigorous 
  of 
  

   mind 
  as 
  ever. 
  That 
  evening 
  there 
  was 
  a 
  recurrence 
  of 
  a 
  slight 
  

   trouble 
  in 
  the 
  action 
  of 
  the 
  heart, 
  of 
  which 
  there 
  had 
  been 
  

   some 
  manifestations 
  in 
  the 
  few 
  months 
  immediately 
  preceding; 
  

   the 
  following 
  day 
  he 
  did 
  not 
  rise, 
  although 
  feeling 
  relieved 
  ; 
  

   in 
  the 
  evening 
  the 
  trouble 
  returned 
  and 
  after 
  a 
  very 
  brief 
  

   period 
  of 
  unconsciousness, 
  he 
  passed 
  quietly 
  away. 
  

  

  The 
  concluding 
  years 
  were 
  marked 
  by 
  an 
  ever 
  increasing 
  

   serenity, 
  and 
  happiness 
  in 
  his 
  work 
  and 
  in 
  the 
  friends 
  about 
  

   him. 
  Up 
  to 
  the 
  last 
  day 
  there 
  was 
  no 
  evidence 
  of 
  diminished 
  

   mental 
  force, 
  though 
  his 
  physical 
  strength 
  was 
  somewhat 
  

   impaired. 
  It 
  was 
  for 
  him 
  a 
  most 
  happy 
  ending 
  of 
  a 
  life, 
  full 
  

   of 
  fruitful 
  activity 
  and 
  honor.
