  him 
  the 
  position 
  of 
  librarian 
  of 
  one 
  of 
  the 
  colleges 
  of 
  his 
  native 
  city. 
  A 
  life 
  

   of 
  confinement 
  was, 
  however, 
  irksome 
  to 
  him, 
  and 
  giving 
  the 
  rein 
  to 
  his 
  love 
  of 
  

   adventure, 
  he 
  wandered 
  over 
  the 
  best 
  part 
  of 
  Europe 
  in 
  search 
  of 
  insects, 
  visit- 
  

   ing 
  Spain, 
  Portugal, 
  Italy, 
  and 
  the 
  isles 
  of 
  the 
  Mediterranean. 
  He 
  also 
  once 
  

   undertook 
  a 
  collecting 
  tour 
  through 
  the 
  Canary 
  Islands, 
  and 
  ascended 
  the 
  Peak 
  

   of 
  Tenerifie 
  in 
  search 
  of 
  specimens, 
  his 
  labors 
  being 
  rewarded 
  by 
  the 
  discovery 
  

   of 
  many 
  species 
  new 
  to 
  science. 
  In 
  the 
  fall 
  of 
  1872 
  he 
  came 
  to 
  America, 
  pass- 
  

   ing 
  some 
  time 
  in 
  Philadelphia, 
  examining 
  and 
  determining 
  species 
  in 
  various 
  

   collections, 
  and 
  arrived 
  in 
  California, 
  full 
  of 
  health 
  and 
  spirits, 
  early 
  in 
  the 
  last 
  

   year. 
  After 
  thoroughly 
  exploring 
  the 
  immediate 
  neighborhood 
  of 
  San 
  Fran- 
  

   cisco, 
  walking 
  nearly 
  every 
  day 
  for 
  several 
  weeks 
  upwards 
  of 
  twenty 
  miles, 
  he 
  

   started 
  on 
  a 
  tour 
  through 
  the 
  southern 
  part 
  of 
  the 
  State, 
  taking 
  Santa 
  Barbara, 
  

   Fort 
  Tejon, 
  San 
  Bernardino 
  and 
  San 
  Diego 
  in 
  his 
  way, 
  wandering 
  even 
  across 
  

   the 
  boundary 
  into 
  the 
  Mohave 
  Desert, 
  sleeping 
  for 
  several 
  nights 
  after 
  the 
  day's 
  

   fatigue 
  in 
  the 
  open 
  air, 
  with 
  no 
  other 
  covering 
  than 
  the 
  clothes 
  he 
  wore. 
  Re- 
  

   turning 
  to 
  San 
  Francisco 
  early 
  in 
  May, 
  he 
  spent 
  some 
  time 
  at 
  various 
  points 
  of 
  

   the 
  Sierra 
  Nevada, 
  and 
  in 
  June 
  started 
  on 
  a 
  prolonged 
  tour 
  through 
  Oregon 
  

   and 
  British 
  Columbia, 
  during 
  which 
  he 
  contracted 
  the 
  disease 
  which 
  has 
  now 
  

   carried 
  him 
  away. 
  He 
  trusted 
  to 
  his 
  training 
  as 
  a 
  gymnast 
  and 
  to 
  his 
  naturally 
  

   strong 
  constitution 
  to 
  bear 
  him 
  through 
  the 
  hardships 
  which 
  he 
  encountered, 
  

   but 
  he 
  was 
  deceived. 
  Nights 
  and 
  days 
  of 
  rough 
  life, 
  with 
  poor 
  and 
  uncertain 
  

   food, 
  sometimes 
  in 
  cold 
  and 
  inhospitable 
  weather, 
  proved 
  too 
  much 
  even 
  for 
  his 
  

   strong 
  frame, 
  and 
  soon 
  after 
  his 
  return 
  to 
  the 
  Eastern 
  States 
  his 
  malady 
  de- 
  

   clared 
  itself. 
  He 
  had 
  accepted 
  an 
  invitation 
  from 
  Professor 
  Agassiz 
  to 
  take 
  

   charge 
  of 
  a 
  portion 
  of 
  the 
  insects 
  in 
  the 
  Museum 
  at 
  Cambridge, 
  and 
  was 
  

   assiduously 
  employed 
  upon 
  their. 
  determination 
  and 
  arrangement 
  when 
  he 
  was 
  

   stricken 
  down. 
  Returning 
  to 
  Philadelphia 
  in 
  April 
  last, 
  he 
  grew 
  gradually 
  

   worse, 
  and 
  though 
  he 
  himself 
  had 
  hope 
  that 
  the 
  summer 
  would 
  bring 
  a 
  change 
  

   for 
  the 
  better 
  in 
  his 
  condition, 
  his 
  friends 
  immediately 
  around 
  him 
  knew 
  and 
  felt 
  

   otherwise. 
  In 
  the 
  last 
  letter 
  I 
  ever 
  received 
  from 
  him, 
  which 
  is 
  dated 
  the 
  

   fourteenth 
  of 
  May, 
  he 
  says 
  : 
  " 
  No 
  leaving 
  here 
  this 
  summer. 
  I 
  have 
  written 
  

   for 
  my 
  brother, 
  who 
  I 
  hope 
  will 
  come 
  to 
  me. 
  At 
  present 
  things 
  look 
  bad, 
  and 
  

   though 
  I 
  eat 
  and 
  drink 
  well, 
  yet 
  the 
  average 
  effect 
  is 
  weaker, 
  and 
  the 
  expectora- 
  

   tion 
  won't 
  slacken. 
  This 
  may 
  be 
  a 
  serious 
  thing, 
  though, 
  of 
  course, 
  my 
  con- 
  

   stitution 
  is 
  in 
  ray 
  favor. 
  Please 
  keep 
  my 
  net 
  and 
  use 
  it 
  — 
  it 
  will 
  be 
  long 
  before 
  

   I 
  need 
  it 
  again. 
  I 
  should 
  like 
  to 
  see 
  you 
  once 
  more; 
  I 
  shall, 
  some 
  day, 
  I 
  hope. 
  

   If 
  I 
  could 
  only 
  be 
  out 
  collecting, 
  somewhere, 
  I 
  am 
  sure 
  I 
  should 
  get 
  well." 
  

   Then, 
  with 
  the 
  ruling 
  passion 
  still 
  strong 
  within 
  the 
  shadow 
  of 
  death, 
  he 
  adds 
  

   in 
  a 
  P. 
  S.: 
  "Let 
  me 
  know 
  what 
  new 
  things 
  you 
  have 
  taken 
  this 
  year." 
  The 
  

   iron 
  hand 
  was 
  too 
  strongly 
  pressed 
  upon 
  him, 
  and 
  even 
  his 
  brother 
  and 
  sister 
  

   arrived 
  too 
  late 
  to 
  receive 
  his 
  parting 
  words. 
  It 
  is, 
  however, 
  gratifying 
  to 
  

   know 
  that 
  his 
  last 
  hours 
  \\ere 
  soothed 
  by 
  the 
  presence 
  of 
  kind 
  and 
  gentle 
  

   friends, 
  and 
  that 
  all 
  that 
  earthly 
  love 
  and 
  attention 
  could 
  do 
  was 
  done, 
  to 
  

   render 
  his 
  passage 
  from 
  the 
  world 
  tranquil 
  and 
  full 
  of 
  peace.
