  MR.

  STRAHA2* 
  ON 
  THE 
  RAISED 
  BEACHES 
  AND 
  [May 
  1 
  897, 
  

  

  consisted 
  of, 
  angular 
  sandstone-blocks, 
  and 
  they 
  had 
  assumed 
  the 
  

   form 
  of 
  moraines, 
  but 
  the 
  valley 
  was 
  too 
  small 
  to 
  have 
  contained 
  more 
  

   than 
  a 
  diminutive 
  glacier. 
  A 
  considerable 
  quantity 
  of 
  talus 
  encum- 
  

   bered 
  the 
  sides 
  of 
  the 
  valley, 
  and 
  a 
  winding 
  stream 
  had 
  cut 
  deeply 
  

   into 
  the 
  hummocky 
  debris, 
  giving 
  an 
  impression 
  of 
  some 
  antiquity 
  

   for 
  the 
  mounds. 
  The 
  scene 
  reminded 
  me 
  of 
  many 
  of 
  our 
  north 
  

   country 
  gills. 
  

  

  The 
  second 
  example 
  referred 
  to 
  consisted 
  of 
  a 
  conspicuous 
  mound 
  

   of 
  sand 
  and 
  pebble-gravel, 
  perched 
  on 
  the 
  hillside 
  north 
  of 
  Yadso, 
  

   a 
  few 
  feet 
  above 
  the 
  level 
  of 
  the 
  highest 
  beach. 
  The 
  mound 
  is 
  

   slightly 
  elongated 
  in 
  an 
  east-and-west 
  direction, 
  and 
  resembles 
  a 
  very 
  

   large 
  oval 
  tumulus, 
  but 
  its 
  size 
  and 
  composition 
  disprove 
  its 
  artificial 
  

   origin, 
  for 
  it 
  contains 
  none 
  of 
  the 
  angular 
  debris 
  which 
  lies 
  round 
  

   its 
  base, 
  but 
  consists 
  wholly 
  of 
  sand 
  and 
  shingle, 
  which 
  would 
  have 
  

   had 
  to 
  be 
  carried 
  from 
  nearly 
  a 
  mile 
  away. 
  Though 
  unusually 
  

   isolated 
  and 
  conspicuous, 
  the 
  mound 
  presents 
  the 
  same 
  general 
  

   features 
  as 
  those 
  that 
  I 
  have 
  seen 
  elsewhere, 
  and 
  as 
  those 
  of 
  many 
  

   eskers 
  in 
  this 
  country, 
  which 
  also 
  often 
  resemble 
  closely 
  great 
  

   tumuli. 
  1 
  

  

  With 
  these 
  exceptions, 
  nearly 
  the 
  whole 
  of 
  the 
  ground 
  that 
  I 
  

   walked 
  over 
  was 
  free 
  from 
  deposits 
  of 
  glacial 
  age. 
  

  

  Glacial 
  Stride. 
  

  

  The 
  shores 
  of 
  the 
  Yaranger 
  Fiord 
  are, 
  of 
  course, 
  conspicuously 
  

   glaciated, 
  though 
  less 
  so 
  on 
  the 
  Gaisa 
  Beds 
  of 
  the 
  northern 
  side 
  than 
  

   on 
  the 
  crystalline 
  rocks 
  of 
  the 
  opposite 
  coast. 
  A 
  finely-striated 
  

   surface, 
  however, 
  occurs 
  at 
  one 
  of 
  the 
  landing-stages 
  on 
  Yadso 
  

   Island, 
  while 
  the 
  spit 
  of 
  land 
  between 
  the 
  Nyborg 
  and 
  Karlbotn 
  

   branches 
  of 
  the 
  fiord 
  is 
  well 
  glaciated 
  all 
  over. 
  The 
  striae 
  there 
  

   range 
  between 
  W. 
  10° 
  N". 
  and 
  W. 
  25° 
  N., 
  and 
  from 
  an 
  inspection 
  

   of 
  a 
  large 
  number 
  of 
  ' 
  roches 
  moutonnees,' 
  we 
  were 
  able 
  to 
  satisfy 
  

   ourselves 
  that 
  the 
  ice 
  moved 
  from 
  west 
  to 
  east 
  — 
  that 
  is, 
  down 
  the 
  

   fiord. 
  The 
  distribution 
  of 
  the 
  boulders 
  supports 
  this 
  conclusion 
  

   in 
  so 
  far 
  as 
  the 
  spit 
  of 
  land 
  approximately 
  divides 
  Gaisa 
  from 
  

   granitic 
  erratics, 
  showing 
  that 
  they 
  have 
  travelled 
  along 
  and 
  not 
  

   across 
  the 
  fiord. 
  

  

  The 
  striae 
  appeared 
  to 
  be 
  earlier 
  than 
  the 
  raised 
  beaches, 
  for 
  they 
  

   are 
  often 
  obliterated 
  under 
  them, 
  though 
  the 
  glaciated 
  form 
  of 
  the 
  

   rock 
  is 
  preserved, 
  as 
  in 
  the 
  case 
  at 
  Bodo 
  referred 
  to 
  above. 
  The 
  

   wave-worn 
  rocks 
  under 
  the 
  highest 
  beach 
  at 
  Yadso 
  form 
  a 
  stronger 
  

   argument, 
  for 
  there 
  the 
  surface 
  remains 
  as 
  it 
  was 
  left 
  at 
  the 
  

   period 
  of 
  the 
  beach, 
  but 
  shows 
  no 
  glaciation. 
  2 
  On 
  the 
  other 
  hand, 
  

   the 
  apparent 
  freshness 
  of 
  some 
  striated 
  surfaces 
  under 
  raised 
  

   beaches 
  led 
  Col. 
  Feilden 
  to 
  conclude 
  that 
  the 
  glaciation 
  went 
  on 
  

   simultaneously 
  with 
  the 
  emergence 
  of 
  the 
  land, 
  3 
  and 
  undoubtedly 
  

  

  1 
  I 
  should 
  mention 
  that 
  Mr. 
  Upton, 
  who 
  accompanied 
  me, 
  was 
  disposed 
  to 
  

   believe 
  the 
  mound 
  to 
  be 
  a 
  tumulus.

  [The 
  observations 
  of 
  Chambers 
  and 
  many 
  other 
  geologists 
  who 
  followed 
  

   him 
  led 
  to 
  the 
  same 
  conclusion 
  on 
  the 
  western 
  coast 
  also. 
  There, 
  too, 
  larga 
  

   erratics 
  lie 
  on 
  the 
  top 
  of 
  the 
  fiord-deposits.]
