  it 
  here. 
  After 
  reaching 
  Parrott 
  City, 
  Dr. 
  Peale, 
  Mr. 
  Atkinson, 
  and 
  

   myself 
  accompanied 
  Mr. 
  Holmes's 
  party 
  on 
  a 
  short 
  trip 
  to 
  the 
  country 
  

   about 
  the 
  head 
  of 
  the 
  Dolores, 
  after 
  which 
  I 
  came 
  to 
  Pueblo 
  with 
  my 
  

   ])arty 
  via 
  Baker's 
  Park, 
  the 
  Rio 
  Grande 
  Valley, 
  and 
  Mosca 
  Pass, 
  reaching 
  

   Pueblo 
  in 
  September. 
  

  

  In 
  1876 
  my 
  party 
  was 
  composed 
  of 
  Dr. 
  A. 
  0. 
  Peale, 
  geologist, 
  Mr. 
  J. 
  

   E. 
  Mushbach, 
  topographical 
  assistant, 
  two 
  packers, 
  and 
  a 
  cook. 
  Mr. 
  

   James 
  Stevenson, 
  general 
  executive 
  officer 
  of 
  the 
  survey, 
  accompanied 
  

   my 
  party 
  during 
  a 
  portion 
  of 
  the 
  trip, 
  as 
  executive 
  officer. 
  

  

  We 
  took 
  the 
  field 
  at 
  Canon 
  City, 
  Colo., 
  on 
  August 
  23. 
  We 
  went 
  up 
  

   the 
  Arkansas, 
  over 
  Marshall's 
  Pass, 
  down 
  the 
  Tomichi 
  and 
  Gunnison 
  to 
  

   the 
  Uncompahgre 
  agency, 
  at 
  the 
  head 
  of 
  the 
  Uncompahgre 
  Valley. 
  

   Here 
  we 
  engaged 
  the 
  services 
  of 
  four 
  Ute 
  Indians, 
  as 
  guides 
  and 
  as 
  a 
  

   sort 
  of 
  escort, 
  to 
  prevent 
  trouble 
  with 
  the 
  band 
  of 
  Indians 
  with 
  whom 
  

   we 
  had 
  a 
  brush 
  the 
  preceding 
  summer, 
  as 
  we 
  were 
  first 
  to 
  finish 
  the 
  

   survey 
  of 
  the 
  country 
  in 
  which 
  they 
  range. 
  This 
  work 
  was 
  completed 
  

   without 
  trouble, 
  after 
  which 
  we 
  returned 
  to 
  the 
  Uncompahgre 
  agency, 
  

   reprovisioned, 
  and 
  started 
  down 
  the 
  Uncompahgre 
  and 
  Gunnison 
  Bivers, 
  

   to 
  survey 
  the 
  part 
  of 
  our 
  district 
  lying 
  north 
  of 
  Grand 
  River. 
  We 
  fol- 
  

   lowed 
  the 
  Salt 
  Lake 
  wagon-trail 
  down 
  the 
  Grand 
  River 
  to 
  the 
  mouth 
  of 
  

   the 
  Dolores, 
  then, 
  leaving 
  the 
  river, 
  we 
  struck 
  north, 
  toward 
  the 
  crest 
  

   of 
  the 
  Roan 
  or 
  Book 
  Clifl's. 
  Reaching 
  their 
  crest, 
  we 
  traveled 
  generally 
  

   eastward 
  along 
  it, 
  on 
  the 
  divide 
  of 
  land 
  between 
  the 
  Grand 
  and 
  White 
  

   Rivers, 
  a 
  route 
  affording 
  magnificent 
  facilities 
  for 
  rapid 
  and 
  accurate 
  

   work. 
  Reaching 
  the 
  head 
  of 
  Roan 
  Creek, 
  we 
  descended 
  into 
  its 
  caiion, 
  

   and 
  followed 
  it 
  down 
  to 
  the 
  Grand. 
  Thence 
  we 
  went 
  up 
  the 
  Grand 
  to 
  

   the 
  eastern 
  edge 
  of 
  the 
  Roan 
  plateau, 
  where 
  our 
  work 
  ended. 
  From 
  

   there 
  we 
  went 
  to 
  Rawlins, 
  Wyo., 
  via 
  White 
  River 
  Indian 
  agency, 
  

   reaching 
  the 
  former 
  point 
  on 
  October 
  23. 
  

  

  Besides 
  the 
  regular 
  topographical 
  work, 
  particular 
  attention 
  has 
  been 
  

   paid 
  to 
  the 
  agricultural 
  capabilities 
  of 
  the 
  country, 
  with 
  a 
  view 
  to 
  ob- 
  

   taining 
  some 
  idea 
  of 
  the 
  extent 
  of 
  arable 
  land. 
  Every 
  considerable 
  

   stream 
  which 
  was 
  crossed 
  was 
  roughly 
  gauged. 
  It 
  is 
  my 
  intention 
  to 
  

   publish 
  in 
  the 
  report 
  for 
  1876 
  a 
  chapter 
  on 
  the 
  physical 
  features 
  of 
  the 
  

   State, 
  its 
  agricultural 
  resources, 
  timber 
  and 
  pasture 
  land, 
  &c. 
  

  

  In 
  closing, 
  I 
  wish 
  to 
  thank 
  Mr, 
  H. 
  F. 
  Bond, 
  late 
  agent 
  at 
  the 
  Los 
  

   Pinos 
  and 
  Uncompahgre 
  agencies, 
  for 
  the 
  great 
  assistance 
  which 
  he 
  has 
  

   afforded 
  me 
  in 
  the 
  prosecution 
  of 
  my 
  work 
  ; 
  also 
  Dr. 
  David 
  Mack, 
  late 
  

   surgeon 
  at 
  these 
  agencies. 
  

  

  Very 
  respectfully, 
  your 
  obedient 
  servant, 
  

  

  HENRY 
  GANNETT, 
  

  

  Topographer.
