﻿VI 
  PREFACE. 
  

  

  scarcely 
  leave 
  a 
  doubt 
  upon 
  this 
  point. 
  It 
  is 
  only 
  right 
  to 
  

   mention 
  that 
  Mr. 
  Fedden 
  seems 
  not 
  to 
  hare 
  had 
  access 
  to 
  

   Mr. 
  Bose's 
  memoir, 
  the 
  publication 
  of 
  which 
  had 
  been 
  much 
  

   delayed 
  for 
  the 
  preparation 
  of 
  one 
  of 
  the 
  maps; 
  but 
  the 
  

   position 
  was 
  sufficiently 
  clear 
  from 
  previous 
  publications. 
  

  

  Although 
  these 
  main 
  facts 
  would 
  seem 
  to 
  settle 
  the 
  corre- 
  

   lation, 
  there 
  are 
  some 
  noteworthy 
  discrepancies 
  in 
  details. 
  

   The 
  Wadhwan 
  group 
  is 
  mostly 
  sandstone, 
  whereas 
  the 
  Bag 
  

   beds 
  are 
  principally 
  limestone. 
  The 
  cherty 
  bands 
  at 
  top 
  would 
  

   recall 
  a 
  Lam 
  eta 
  character 
  of 
  the 
  Bag 
  area. 
  But 
  the 
  chief 
  

   point 
  of 
  contrast 
  with 
  Bag 
  beds 
  is 
  the 
  association 
  of 
  trap 
  rock 
  

   with 
  the 
  upper 
  beds 
  of 
  the 
  Wadhwan 
  group. 
  This 
  is 
  implied 
  

   in 
  several 
  places 
  and 
  is 
  directly 
  affirmed 
  on 
  page 
  18, 
  notwith- 
  

   standing 
  the 
  previously 
  described 
  deep 
  erosion-unconformity 
  

   with 
  the 
  trap. 
  It 
  may 
  be 
  that 
  some 
  of 
  these 
  cases 
  are 
  only 
  

   contact-effects 
  ; 
  and 
  that 
  in 
  others, 
  beds 
  have 
  been 
  taken 
  as 
  

   of 
  the 
  Wadhwan 
  group 
  which 
  should 
  have 
  been 
  placed 
  in 
  

   the 
  succeeding 
  Trappean 
  -grits. 
  

  

  Some 
  vernacular 
  words 
  are 
  quite 
  needlessly 
  introduced 
  in 
  

   Mr. 
  Fedden's 
  text. 
  Foreign 
  readers 
  may 
  like 
  to 
  know 
  that 
  

   wala 
  means 
  a 
  stream, 
  or 
  rather 
  its 
  channel; 
  talao 
  is 
  a 
  tank 
  ; 
  

   and 
  talao?H, 
  I 
  imagine, 
  a 
  little 
  tank, 
  or 
  perhaps 
  a 
  pond. 
  

  

  The 
  description 
  of 
  the 
  sequence 
  of 
  formations 
  in 
  Kathiawar 
  

   seems 
  to 
  me 
  to 
  necessitate 
  a 
  correction 
  of 
  the 
  sequence 
  in 
  the 
  

   lower 
  Narbada 
  area 
  as 
  described 
  by 
  Mr. 
  Bose 
  in 
  the 
  first 
  part 
  

   of 
  this 
  volume, 
  regarding 
  the 
  affiliation 
  of 
  his 
  Nimar-sand- 
  

   stone, 
  ranked 
  by 
  him 
  as 
  lower-cretaceous. 
  The 
  probabilities 
  

   were 
  already 
  decidedly 
  against 
  this 
  view 
  (see 
  Manual, 
  page 
  

   221), 
  and 
  he 
  has 
  shown 
  no 
  sufficient 
  ground 
  for 
  disregarding 
  

   them. 
  In 
  the 
  original 
  cursory 
  survey 
  of 
  that 
  ground 
  by 
  Mr.
