  CHAPTER 
  I. 
  

  

  PRELIMINARY. 
  

  

  Literature. 
  — 
  The 
  area 
  comprised 
  in 
  this 
  memoir 
  has 
  occupied 
  me 
  three 
  

   working 
  seasons 
  (1880 
  — 
  83). 
  It 
  had 
  been 
  surveyed 
  geologically 
  by 
  

   Messrs. 
  W. 
  T. 
  Blanford 
  and 
  A. 
  B. 
  Wynne 
  seventeen 
  years 
  ago. 
  As 
  no 
  

   accurate 
  topographical 
  maps 
  of 
  the 
  territory 
  were 
  available 
  at 
  the 
  time, 
  

   that 
  survey 
  was 
  professedly 
  preliminary. 
  The 
  work, 
  however, 
  was 
  as 
  

   satisfactory 
  as 
  could 
  be 
  expected 
  under 
  the 
  circumstances, 
  and 
  has 
  been 
  

   reported 
  on 
  with 
  consummate 
  ability 
  by 
  Mr. 
  Blanford. 
  1 
  This 
  has, 
  in 
  one 
  

   sense, 
  been 
  a 
  disadvantage 
  to 
  me. 
  On 
  the 
  other 
  hand, 
  Mr. 
  Blanford's 
  

   memoir 
  has 
  served 
  me 
  — 
  a 
  novice 
  in 
  field-work 
  — 
  as 
  a 
  mos 
  trustworthy 
  

   guide 
  ; 
  and 
  I 
  have 
  to 
  acknowledge 
  my 
  indebtedness 
  to 
  it.
