  It 
  narrows 
  gradually 
  as 
  it 
  approaches 
  the 
  place 
  of 
  excavation, 
  

   until 
  it 
  finally 
  ends 
  about 
  10 
  feet 
  from 
  this 
  place. 
  In 
  the 
  

   photograph 
  the 
  foot 
  of 
  the 
  cliff 
  lies 
  in 
  such 
  deep 
  shadow 
  that 
  

   the 
  extreme 
  prolongation 
  of 
  this 
  terrace 
  is 
  not 
  visible. 
  The 
  

   terrace 
  appears 
  to 
  be 
  composed, 
  almost 
  entirely, 
  of 
  material 
  

   that 
  has 
  fallen 
  from 
  above. 
  In 
  the 
  opposite 
  direction 
  (N. 
  W.) 
  

   from 
  the 
  place 
  of 
  excavation, 
  and 
  about 
  60 
  feet 
  distant 
  from 
  it, 
  

   is 
  a 
  somewhat 
  confused 
  mass 
  of 
  talus 
  material. 
  As 
  this 
  is 
  

   separated 
  from 
  the 
  previously 
  described 
  terrace 
  by 
  a 
  gap 
  of 
  

   only 
  about 
  70 
  feet, 
  it 
  is 
  quite 
  possible 
  that 
  these 
  two 
  masses 
  of 
  

   fallen 
  gravel 
  may 
  have 
  been 
  connected, 
  at 
  some 
  earlier 
  time, 
  

   by 
  an 
  intermediate 
  portion 
  that 
  has 
  been 
  cut 
  away 
  during 
  

   recent 
  improvement 
  and 
  widening 
  of 
  the 
  road. 
  In 
  fact 
  the 
  

   general 
  character 
  of 
  that 
  part 
  of 
  the 
  slope 
  lying 
  between 
  the 
  

   road 
  and 
  the 
  brook-bed, 
  at 
  the 
  bottom 
  of 
  the 
  quebrada, 
  makes 
  

   this 
  seem 
  probable. 
  Whether 
  these 
  masses 
  of 
  talus 
  were 
  con- 
  

   tinuous 
  or 
  not, 
  there 
  must 
  have 
  been, 
  from 
  time 
  to 
  time, 
  con- 
  

   siderable 
  quantities 
  of 
  gravel 
  falling 
  from 
  the 
  top 
  and 
  face 
  of 
  

   the 
  cliff 
  over 
  the 
  place 
  where 
  the 
  bones 
  were 
  found. 
  

  

  The 
  diagrams, 
  arranged 
  under 
  'fig. 
  2, 
  represent 
  three 
  pos- 
  

   sible 
  stages 
  of 
  development 
  at 
  the 
  foot 
  of 
  the 
  quebrada 
  wall 
  

   where 
  the 
  excavation 
  was 
  made. 
  A 
  grave 
  containing 
  human 
  

   remains 
  may 
  have 
  been 
  left 
  open 
  in 
  the 
  face 
  of 
  the 
  gravel 
  cliff, 
  

   as 
  indicated 
  in 
  Section 
  I. 
  This 
  seems 
  to 
  have 
  been 
  one 
  form 
  

   of 
  burial 
  practiced 
  by 
  the 
  Indians 
  of 
  the 
  region. 
  Many 
  open 
  

   graves 
  of 
  this 
  character 
  were 
  observed 
  in 
  the 
  face 
  of 
  a 
  steep 
  

   gravel 
  bank 
  in 
  the 
  neighborhood 
  of 
  Urubamba, 
  one 
  day's 
  ride 
  

   from 
  Cuzco 
  ; 
  and 
  it 
  is 
  interesting 
  to 
  note 
  that 
  none 
  of 
  these 
  

   graves 
  that 
  I 
  was 
  able 
  to 
  examine 
  contained 
  entire 
  skeletons, 
  

   merely 
  disarticulated 
  or 
  fragmentary 
  bones. 
  Section 
  II 
  shows 
  

   the 
  result 
  of 
  an 
  enlargement 
  of 
  the 
  talus. 
  Gravel 
  deposited 
  at 
  

   this 
  point 
  would 
  fill 
  the 
  open 
  grave, 
  and 
  would 
  closely 
  simulate 
  

   the 
  basal 
  gravel 
  of 
  the 
  cliff. 
  The 
  filling 
  would, 
  however, 
  tend 
  

   to 
  be 
  somewhat 
  less 
  compact 
  at 
  the 
  top 
  of 
  the 
  grave 
  than 
  at 
  

   the 
  bottom, 
  and 
  a 
  shallow 
  " 
  break 
  " 
  might 
  develop 
  under 
  the 
  

   roof 
  of 
  the 
  grave 
  when 
  the 
  filling 
  had 
  settled. 
  In 
  section 
  III 
  

   the 
  trail, 
  known 
  as 
  the 
  lower 
  road 
  to 
  Ant 
  a, 
  has 
  been 
  improved 
  

   and 
  widened 
  by 
  removing 
  a 
  considerable 
  quantity 
  of 
  gravel 
  

   from 
  the 
  talus 
  and 
  also 
  from 
  the 
  face 
  of 
  the 
  cliff. 
  At 
  this 
  

   stage 
  the 
  inner 
  portion 
  only 
  of 
  the 
  grave 
  is 
  left 
  ; 
  and 
  the 
  

   greater 
  part 
  of 
  its 
  original 
  contents, 
  already 
  broken 
  and 
  dis- 
  

   placed 
  by 
  decay 
  and 
  by 
  the 
  impact 
  of' 
  the 
  falling 
  gravel, 
  if 
  not 
  

   by 
  inquisitive 
  and 
  ceremonial 
  visitors, 
  has 
  been 
  cut 
  away 
  by 
  

   the 
  mattocks 
  of 
  the 
  road-menders. 
  

  

  The 
  foregoing 
  explanation 
  of 
  the 
  occurrence 
  of 
  vertebrate 
  

   remains 
  at 
  this 
  place 
  in 
  the 
  quebrada 
  would 
  apply 
  to 
  almost 
  

   any 
  time 
  during 
  the 
  three 
  centuries 
  and 
  a 
  half 
  that 
  have 
  

   elapsed 
  since 
  the 
  Spaniards 
  brought 
  domestic 
  cattle 
  to 
  Peru 
  ;
