  the 
  Middle 
  Park 
  and 
  over 
  the 
  Boulder 
  Pass 
  to 
  the 
  sources 
  of 
  the 
  Big 
  

   Thompsoa 
  Creek, 
  aa 
  importaut 
  stream 
  risiug 
  ou 
  the 
  east 
  side 
  of 
  the 
  

   Long's 
  Peak 
  group. 
  Much 
  excellent 
  work 
  was 
  done 
  in 
  the 
  ridges 
  of 
  

   hogbacks 
  at 
  the 
  east 
  base 
  of 
  the 
  mountains, 
  thus 
  bringing 
  the 
  season's 
  

   labors 
  to 
  a 
  most 
  successful 
  termination. 
  One 
  hundred 
  and 
  six 
  stations 
  

   were 
  made 
  ; 
  barometrical 
  elevations 
  were 
  450 
  ; 
  and 
  the 
  number 
  of 
  eleva- 
  

   tions 
  taken 
  with 
  the 
  gradienter 
  were 
  about 
  6,000. 
  

  

  The 
  party 
  under 
  Mr. 
  Gardner 
  had 
  made 
  but 
  four 
  stations 
  when 
  it 
  

   was 
  prevented 
  from 
  further 
  prosecution 
  of 
  that 
  duty 
  by 
  Indians. 
  One 
  

   of 
  the 
  stations 
  occupied 
  was 
  very 
  important, 
  viz, 
  the 
  Sierra 
  la 
  Sal 
  

   Mountain, 
  which 
  enabled 
  Mr. 
  Gardner 
  to 
  secure 
  an 
  excellent 
  set 
  of 
  

   observations, 
  thus 
  extending 
  the 
  triangulation 
  far 
  into 
  Utah, 
  and 
  con- 
  

   necting 
  our 
  eastern 
  work 
  with 
  the 
  great 
  Colorado 
  River 
  of 
  the 
  West. 
  

  

  During 
  the 
  latter 
  part 
  of 
  the 
  season 
  of 
  1874, 
  Mr. 
  W. 
  H. 
  Jackson, 
  the 
  

   photographer 
  of 
  the 
  United 
  States 
  Geological 
  Survey, 
  in 
  connection 
  

   with 
  Mr. 
  Ernest 
  Ingersoll, 
  visited 
  the 
  southwestern 
  portion 
  of 
  Colo- 
  

   rado 
  for 
  the 
  purpose 
  of 
  photographing 
  the 
  ruins 
  which 
  rumor 
  had 
  

   placed 
  in 
  the 
  canons 
  of 
  the 
  Mesa 
  Verde 
  and 
  about 
  El 
  Late. 
  The 
  

   season 
  was 
  far 
  advanced, 
  and 
  there 
  was 
  but 
  little 
  time 
  for 
  investi- 
  

   gation, 
  yet 
  the 
  eight 
  days 
  that 
  were 
  actually 
  devoted 
  to 
  the 
  subject 
  

   brought 
  to 
  light 
  a 
  group 
  of 
  ancient 
  habitations 
  so 
  novel 
  in 
  their 
  con- 
  

   struction 
  and 
  position 
  that 
  they 
  have 
  excited 
  a 
  very 
  general 
  interest. 
  

   The 
  results 
  of 
  the 
  trip, 
  as 
  pui)lished 
  in 
  Bulletin 
  No. 
  1, 
  second 
  series, 
  of 
  

   the 
  Survey, 
  have 
  already 
  been 
  widely 
  distributed. 
  The 
  illustrations 
  

   secured 
  by 
  photography, 
  and 
  then 
  reproduced 
  by 
  photolithograi)hic 
  

   processes, 
  have 
  done 
  much 
  to 
  popularize 
  and 
  render 
  familiar 
  the 
  lead- 
  

   ing 
  features 
  of 
  the 
  subject, 
  and, 
  showing 
  as 
  they 
  do 
  all 
  the 
  phases 
  of 
  

   the 
  eccentric 
  methods 
  of 
  these 
  ancient 
  builders, 
  has 
  made 
  them 
  an 
  

   authority, 
  and 
  they 
  have 
  already 
  been 
  reproduced 
  in 
  a 
  number 
  of 
  later 
  

   publications. 
  

  

  The 
  first 
  trip 
  proving 
  so 
  successful, 
  Mr. 
  Jackson 
  was 
  dispatched 
  again 
  

   this 
  season 
  to 
  the 
  same 
  region 
  with 
  instructions 
  to 
  ascertain, 
  as 
  far 
  as 
  

   possible, 
  the 
  extent 
  and 
  distribution 
  of 
  these 
  ruins 
  north 
  of 
  the 
  present 
  

   Moquis 
  Pueblos. 
  Associated 
  with 
  him 
  in 
  the 
  enterprise 
  was 
  Mr. 
  E. 
  A. 
  

   Barber, 
  special 
  correspondent 
  of 
  the 
  New 
  York 
  Herald. 
  A 
  guide, 
  two 
  

   packers, 
  and 
  a 
  cook 
  constituted 
  the 
  whole 
  party, 
  and 
  then, 
  with 
  six 
  

   weeks' 
  supplies, 
  the 
  party 
  started 
  from 
  Parrott 
  City, 
  on 
  the 
  head 
  of 
  the 
  

   Eio 
  La 
  Plata, 
  August 
  27, 
  the 
  general 
  course 
  being 
  down 
  the 
  Rio 
  San 
  

   Juan 
  to 
  the 
  De 
  Chelly, 
  up 
  that 
  to 
  near 
  Fort 
  Defiance, 
  and 
  then 
  over 
  to 
  

   the 
  seven 
  Moqui 
  " 
  cities". 
  Returning, 
  they 
  crossed 
  the 
  San 
  Juan 
  at 
  the 
  

   mouth 
  of 
  the 
  De 
  Chelly, 
  and 
  traveled 
  northward 
  to 
  midway 
  between 
  the 
  

   Sierra 
  Abajo 
  and 
  La 
  Sal, 
  and 
  then 
  returned 
  to 
  the 
  starting-point 
  across 
  

   the 
  heads 
  of 
  the 
  caiions, 
  which 
  run 
  southward 
  to 
  the 
  San 
  Juan. 
  

  

  The 
  Upper 
  San 
  Juan, 
  Mesa 
  Verde, 
  and 
  El 
  Late 
  regions 
  came 
  within 
  

   the 
  area 
  assigned 
  Mr. 
  W. 
  H. 
  Holmes, 
  who, 
  in 
  addition 
  to 
  his 
  geological 
  

   investigations, 
  made 
  a 
  special 
  examination 
  of 
  the 
  archasology 
  of 
  the
