  Sir- 
  I 
  herewith 
  transmit 
  my 
  le.port 
  on 
  the 
  principal 
  topographical 
  

   features 
  of 
  the 
  district 
  surveyed 
  by 
  the 
  southern 
  division 
  during 
  the 
  

   summer, 
  1875. 
  Also, 
  a 
  topographical 
  report 
  by 
  Franklm 
  Rhoda, 
  who 
  

   'nJs 
  my 
  assistant 
  in 
  the 
  field. 
  Dr. 
  F. 
  M. 
  Endlich 
  will 
  report 
  on 
  the 
  

   geology 
  and 
  the 
  mineralogy 
  of 
  the 
  district 
  esammed. 
  

  

  ThI 
  party 
  outfitting 
  at 
  Denver 
  took 
  the 
  field 
  June 
  6. 
  Our 
  supplies, 
  

   instruments, 
  and 
  baggage 
  were 
  transported 
  on 
  eight 
  pack-mules, 
  carry- 
  

   ing 
  only 
  such 
  things 
  as 
  were 
  absolutely 
  necessary. 
  Thus, 
  having 
  no 
  

   incumbrances, 
  we 
  were 
  enabled 
  to 
  travel 
  very 
  rapidly 
  and 
  to 
  pass 
  through 
  

   the 
  rough 
  mountains, 
  where 
  otherwise 
  we 
  might 
  have 
  been 
  compelled 
  to 
  

   make 
  long 
  detours 
  to 
  avoid 
  rough 
  passes.

  i.i.,i„f. 
  

  

  The 
  pafty 
  returned 
  to 
  Denver 
  on 
  October 
  12, 
  having 
  obtained 
  the 
  data 
  

   with 
  which 
  to 
  map 
  (both 
  topographically 
  and 
  geologically) 
  the 
  district 
  

   assigned 
  this 
  division, 
  which 
  comprised 
  an 
  area 
  of 
  12 
  000 
  square 
  miles. 
  

   Within 
  this 
  area 
  we 
  have 
  established 
  one 
  hundred 
  and 
  forty-three 
  topo- 
  

   araphical 
  stations 
  on 
  the 
  more 
  prominent 
  peaks 
  of 
  this 
  district. 
  

  

  I 
  wish 
  here 
  to 
  acknowledge 
  the 
  many 
  obligations 
  I 
  am 
  under 
  to 
  Dr. 
  

   F 
  M 
  Endlich 
  and 
  Franklin 
  Rhoda, 
  for 
  their 
  hearty 
  co-operatiou 
  and 
  

   uniform 
  kindness 
  which 
  they 
  displayed 
  during 
  the 
  three 
  seasons 
  they 
  

   accompanied 
  me 
  in 
  the 
  prosecution 
  of 
  this 
  work. 
  

  

  Owing 
  to 
  the 
  pressure 
  of 
  other 
  matters, 
  I 
  have 
  not 
  been 
  able 
  to 
  work 
  

   up 
  the 
  material 
  on 
  hand 
  in 
  time 
  for 
  this 
  report. 
  

  

  Hoping 
  that 
  this 
  may 
  meet 
  your 
  approval, 
  

  

  I 
  am, 
  very 
  respectfully, 
  your 
  obedient 
  servant,
