  Scoured 
  Bowlders 
  of 
  the 
  Mattawa 
  Valley.

  about 
  eighteen 
  or 
  twenty 
  inches 
  across 
  at 
  the 
  top, 
  but 
  tapers 
  to 
  

   about 
  eight 
  or 
  ten 
  inches 
  at 
  the 
  bottom. 
  The 
  bowlder 
  has 
  evi- 
  

   dently 
  been 
  slightly 
  tilted 
  since 
  it 
  was 
  bored 
  out, 
  and 
  may, 
  

   indeed, 
  have 
  been 
  moved 
  a 
  considerable 
  distance. 
  It 
  lies 
  at 
  

   the 
  edge 
  of 
  the 
  water 
  a 
  few 
  rods 
  up 
  stream 
  from 
  the 
  residence 
  

   of 
  the 
  Hon. 
  James 
  B. 
  Klock, 
  and 
  is 
  readily 
  visible 
  only 
  at 
  low 
  

   water. 
  

  

  From 
  the 
  Rev. 
  E. 
  Macnab 
  of 
  Mattawa 
  the 
  writer 
  learned 
  of 
  

   another 
  ring-bowlder 
  which 
  may 
  be 
  seen 
  on 
  the 
  bank 
  of 
  Lake 
  

   Temiscamang 
  at 
  the 
  narrows 
  at 
  old 
  Fort 
  Temiscamang 
  near 
  

   Baie 
  des 
  Peres. 
  In 
  this 
  case 
  a 
  tree 
  grew 
  up 
  through 
  the 
  aper- 
  

   ture 
  and 
  finally 
  broke 
  the 
  bowlder 
  in 
  two. 
  The 
  stone 
  was 
  

   literally 
  strung 
  on 
  the 
  tree. 
  

  

  Basined 
  bowlders 
  are 
  much 
  more 
  numerous. 
  They 
  are 
  fairly 
  

   abundant 
  in 
  the 
  rapids 
  of 
  the 
  ancient 
  outlet 
  at 
  Des 
  Epines 
  rapids 
  

   and 
  at 
  Mattawa 
  and 
  also 
  in 
  several 
  of 
  those 
  of 
  the 
  modern 
  Mat- 
  

   tawa 
  and 
  Ottawa. 
  They 
  exist 
  in 
  all 
  stages 
  of 
  development 
  rang- 
  

   ing 
  from 
  a 
  saucer-like 
  depression 
  barely 
  deep 
  enough 
  to 
  hold 
  a 
  

   spoonful 
  of 
  water 
  to 
  well-developed 
  potholes 
  a 
  foot 
  or 
  more 
  in 
  

   depth. 
  Occasionally 
  one 
  is 
  found 
  which 
  is 
  very 
  irregular 
  in 
  shape 
  

   — 
  a 
  peculiarity 
  which 
  is 
  generally 
  due 
  to 
  some 
  unevennessin 
  the 
  

   composition 
  of 
  the 
  rock. 
  Several 
  bowlders 
  were 
  found 
  in 
  which 
  

   a 
  well-developed 
  basin 
  had 
  a 
  deep 
  cut 
  in 
  the 
  rim 
  or 
  on 
  one 
  side. 
  

   This 
  appeared 
  to 
  be 
  due 
  to 
  the 
  wearing 
  through 
  of 
  a 
  thin 
  side 
  

   wall. 
  A 
  good 
  specimen 
  of 
  this 
  modified 
  form 
  lies 
  on 
  the 
  edge 
  

   of 
  the 
  railroad 
  cut 
  about 
  forty 
  feet 
  south 
  of 
  the 
  overhead 
  

   bridge 
  opposite 
  O'Farrell's 
  hotel 
  in 
  Mattawa. 
  This 
  one 
  is 
  

   about 
  35 
  or 
  40 
  feet 
  above 
  low 
  water 
  in 
  the 
  Mattawa. 
  Many 
  

   basined 
  bowlders 
  were 
  found 
  at 
  heights 
  from 
  fifteen 
  or 
  twenty 
  

   up 
  to 
  about 
  forty 
  feet 
  on 
  ground 
  east 
  and 
  southeast 
  of 
  the 
  

   hotel. 
  On 
  the 
  north 
  bank 
  at 
  Des 
  Epines 
  rapids 
  three 
  good 
  

   specimens 
  were 
  found 
  forty 
  feet 
  above 
  the 
  modern 
  Mattawa 
  

   and 
  several 
  others 
  were 
  found 
  at 
  lower 
  levels. 
  

  

  Niched 
  bowlders 
  that 
  can 
  be 
  surely 
  distinguished 
  from 
  other 
  

   forms 
  are 
  hardly 
  so 
  common 
  as 
  the 
  basined 
  variety. 
  The 
  niche 
  

   is 
  a 
  shallow 
  hollow 
  worn 
  into 
  the 
  side 
  of 
  the 
  bowlder, 
  in 
  form 
  

   somewhat 
  resembling 
  a 
  wall-niche 
  for 
  statues 
  or 
  statuettes. 
  A 
  

   number 
  of 
  examples 
  were 
  found 
  at 
  Mattawa 
  concerning 
  which 
  

   there 
  can 
  be 
  no 
  doubt. 
  For 
  the 
  bowlder 
  had 
  evidently 
  

   received 
  its 
  marks 
  of 
  scour 
  in 
  situ. 
  This 
  was 
  the 
  case 
  with 
  

   the 
  great 
  bowlders 
  especially. 
  In 
  the 
  case 
  of 
  many 
  small 
  

   bowlders, 
  however, 
  the 
  worn 
  cavities 
  may 
  have 
  had 
  a 
  different 
  

   origin. 
  If 
  a 
  small 
  bowlder 
  had 
  a 
  small 
  shallow 
  basin 
  worn 
  on 
  

   its 
  top 
  and 
  then 
  had 
  been 
  turned 
  over 
  on 
  its 
  side, 
  the 
  basin 
  

   would 
  then 
  have 
  the 
  appearance 
  of 
  a 
  true 
  niche. 
  No 
  doubt 
  

   many 
  have 
  had 
  this 
  origin. 
  But 
  in 
  several 
  instances 
  it 
  was 
  

   plain 
  that 
  the 
  niche 
  had 
  been 
  worn 
  while 
  the 
  bowlder 
  was 
  in 
  

   exactly 
  the 
  same 
  position 
  as 
  to-day.
