  conglomerate 
  is 
  very 
  soon 
  lost 
  sight 
  of, 
  going 
  North, 
  and 
  may 
  he 
  

   said 
  to 
  cease 
  almost 
  at 
  once 
  as 
  an 
  independent 
  bed., 
  though 
  re 
  -appearing 
  

   here 
  and 
  there 
  at 
  intervals. 
  It 
  may 
  be 
  recognised, 
  for 
  instance, 
  a 
  little 
  

   North 
  of 
  Yaytho 
  stream 
  on 
  the 
  coast 
  between 
  Broken 
  Point 
  and 
  

   Kyoungthah 
  (Chougdar). 
  The 
  rocks 
  along 
  the 
  shore 
  here 
  are 
  thick- 
  

   bedded 
  massive 
  sandstones, 
  mingled 
  with 
  which 
  a 
  thin 
  string 
  of 
  con- 
  

   glomerate 
  occurs, 
  rather 
  irregularly, 
  composed 
  mainly 
  of 
  small 
  white 
  

   quartz 
  pebbles 
  with 
  a 
  little 
  shaly 
  detritus 
  as 
  elsewhere. 
  Some 
  few 
  miles 
  

   South 
  of 
  Matha, 
  strings 
  of 
  fine 
  conglomerate 
  are 
  noticed 
  in 
  the 
  sandstone, 
  

   and 
  still 
  further 
  North, 
  between 
  Kyouk-kyon 
  and 
  Gwah, 
  considerable 
  

   bands 
  of 
  a 
  coarse 
  conglomerate, 
  made 
  up 
  of 
  shaly 
  and 
  cherty 
  fragments, 
  

   are 
  dispered 
  through 
  the 
  sandstone, 
  all 
  which 
  represent, 
  probably 
  within 
  

   narrow 
  limits, 
  what 
  may 
  be 
  called 
  a 
  common 
  horizon. 
  These 
  thick- 
  

   bedded 
  sandstones 
  are 
  often 
  tilted 
  up 
  at 
  high 
  angles, 
  but 
  are 
  more 
  usually 
  

   seen 
  either 
  horizontal 
  or 
  dipping 
  at 
  low 
  angles. 
  In 
  addition 
  to 
  the 
  

   cancellated 
  form 
  of 
  weathering, 
  the 
  rock 
  is 
  sometimes 
  seen 
  with 
  a 
  ten- 
  

   dency 
  to 
  divide 
  into 
  polygonal 
  fragments, 
  the 
  fissures 
  separating 
  which 
  

   seem 
  to 
  originate 
  spontaneously, 
  the 
  nucleus 
  of 
  each 
  fragment 
  re- 
  

   taining 
  the 
  original 
  green 
  or 
  bluish 
  hue 
  of 
  the 
  undecayed 
  rock, 
  while 
  

   the 
  fissures 
  are 
  represented 
  by 
  yellow 
  bands, 
  as 
  though 
  the 
  result 
  of 
  

   chemical 
  rather 
  than 
  mechanical 
  causes. 
  

  

  Nowhere 
  is 
  the 
  variable 
  character 
  of 
  the 
  beds 
  of 
  this 
  group 
  better 
  

   displayed 
  than 
  along 
  the 
  coast 
  immediately 
  North 
  of 
  Cape 
  Negrais. 
  Below 
  

   the 
  point 
  where 
  the 
  Ywot-pa 
  stream 
  falls 
  into 
  the 
  sea, 
  beds 
  are 
  exposed 
  

   very 
  similar 
  in 
  general 
  character 
  to 
  those 
  already 
  given 
  in 
  the 
  section 
  

   near 
  Matha, 
  higher 
  up 
  the 
  coast. 
  These 
  beds 
  contain 
  crushed 
  carbo- 
  

   naceous 
  trunks 
  and 
  branches, 
  and 
  dip 
  at 
  angles 
  varying 
  from 
  10° 
  to 
  

   40° 
  East-by-north. 
  South 
  of 
  these 
  beds, 
  thin 
  shaly 
  sandstones, 
  quite 
  

   unaltered, 
  come 
  in, 
  dipping 
  15° 
  West-by-north. 
  Nearer 
  Negrais, 
  a 
  thick 
  

   series 
  of 
  dark 
  shales, 
  with 
  subordinate 
  beds 
  of 
  cherty 
  limestone, 
  comes 
  

   in, 
  displaying 
  signs 
  of 
  having 
  been 
  subjected 
  to 
  great 
  mechanical 
  strain
