  trade 
  of 
  an 
  engraver 
  of 
  watch 
  

   cases 
  and 
  maker 
  of

  He 
  must 
  have 
  devoted 
  

   all 
  of 
  his 
  spare 
  time 
  to 
  researches 
  among 
  the 
  mosses 
  and 
  

   particularly 
  the 
  peat 
  swamps, 
  for 
  in 
  1844 
  he 
  presented 
  to 
  the 
  

   local 
  society 
  a 
  memoir 
  entitled,

  Quelques

  In 
  1845 
  he 
  was 
  commissioned 
  

   by 
  the 
  Prussian 
  government 
  to 
  study 
  the 
  peat 
  formation 
  in 
  

   northern 
  Europe. 
  

  

  In 
  1848 
  he 
  came 
  to 
  the 
  United 
  States 
  and 
  settled- 
  at 
  once 
  

   in 
  Columbus, 
  Ohio, 
  where 
  he 
  resided 
  until 
  his 
  death. 
  His 
  

   study 
  of 
  the 
  formation 
  of 
  peat 
  naturally 
  led 
  him 
  to 
  take 
  an 
  in- 
  

   terest 
  in 
  the 
  plants 
  which 
  grew 
  in 
  the 
  geologic 
  peat 
  bogs, 
  and 
  

   it 
  is 
  easy 
  to 
  trace 
  the 
  lines 
  of 
  divergence 
  of 
  his 
  two 
  chosen 
  

   subjects. 
  Of 
  his 
  studies 
  among 
  the 
  fossil 
  plants 
  we 
  have 
  not 
  

   knowledge 
  to 
  speak, 
  further 
  than 
  to 
  say 
  that 
  in 
  this 
  field 
  he 
  

   was 
  an 
  acknowleged 
  authority, 
  and 
  it 
  was 
  the 
  one 
  which 
  he 
  

   most 
  loved 
  and 
  was 
  able 
  longest 
  to 
  pursue.^ 
  

  

  Lesquereux 
  soon 
  became 
  acquainted 
  with 
  Sullivant 
  at 
  

   Columbus, 
  and 
  was 
  employed 
  by 
  him 
  to 
  make 
  a 
  collecting 
  

   tour 
  through 
  parts 
  of 
  the 
  Southern 
  states. 
  The 
  mosses 
  

   which 
  were 
  thus 
  •accumulated, 
  together 
  with 
  many 
  others, 
  

   were 
  issued 
  in 
  1856 
  under 
  the 
  title

  numbered 
  416 
  species 
  and

  this,

   well 
  as 
  of 
  the

  which 
  appeared 
  in 
  1865 
  and 
  

   numbered 
  nearly 
  500 
  species, 
  there 
  were 
  only 
  50 
  copies. 
  In 
  

   1859, 
  in 
  conjunction 
  with 
  Sullivant, 
  he 
  published 
  in
