  On 
  the 
  Pembina 
  River 
  in 
  northern 
  Alberta, 
  Mr. 
  McEvoy 
  

   reports 
  : 
  

  

  " 
  Several 
  outcrops 
  of 
  coal 
  occur 
  on 
  the 
  banks 
  of 
  the 
  river, 
  prin- 
  

   cipally 
  above 
  the 
  crossing. 
  The 
  coal 
  has 
  been 
  on 
  fire 
  here 
  years 
  

   ago, 
  and 
  the 
  overlying 
  beds 
  of 
  clay 
  and 
  shale 
  have 
  fallen 
  in, 
  giv- 
  

   ing 
  a 
  very 
  disturbed 
  appearance 
  to 
  the 
  locality. 
  The 
  white 
  clay 
  

   is 
  partly 
  burned 
  to 
  a 
  pale 
  red 
  terra 
  cotta. 
  Half 
  a 
  mile 
  above 
  the 
  

   crossing, 
  on 
  the 
  east 
  side, 
  a 
  seam 
  of 
  coal 
  17 
  feet 
  10 
  inches 
  thick 
  

   is 
  exposed, 
  of 
  which 
  the 
  upper 
  four 
  feet 
  is 
  impure. 
  On 
  the 
  oppo- 
  

   site 
  side 
  there 
  is 
  a 
  seam 
  13 
  feet 
  thick, 
  having 
  four 
  small 
  partings 
  

   of 
  clay 
  and 
  carbonaceous 
  shale, 
  amounting 
  in 
  all 
  to 
  nine 
  inches." 
  

  

  Dr. 
  Adams 
  in 
  his 
  study 
  of 
  the 
  Grenville 
  series 
  in 
  Monmouth 
  

   reports 
  important 
  evidence 
  of 
  their 
  sedimentary 
  origin. 
  He 
  says 
  : 
  

  

  "The 
  study 
  of 
  the 
  Grenville 
  series 
  in 
  Monmouth 
  showed 
  

   beyond 
  a 
  doubt, 
  that 
  this 
  series 
  is 
  a 
  sedimentary 
  one. 
  It 
  includes 
  

   a 
  great 
  development 
  of 
  bedded 
  white 
  quartzites, 
  evidently 
  altered 
  

   sandstones. 
  The 
  associated 
  limestones 
  also, 
  that 
  occur 
  in 
  heavy 
  

   bands, 
  and, 
  as 
  everywhere 
  else 
  in 
  the 
  Grenville 
  series 
  are 
  in 
  the 
  

   form 
  of 
  white 
  crystalline 
  marbles, 
  were 
  in 
  a 
  few 
  places 
  along 
  the 
  

   line 
  of 
  the 
  Irondale, 
  Bancroft 
  and 
  Ottawa 
  Railway, 
  seen 
  to 
  

   hold 
  little 
  dark 
  strings 
  suggestive 
  of 
  remnants 
  of 
  the 
  original 
  

   limestone 
  in 
  a 
  less 
  altered 
  condition. 
  On 
  this 
  account, 
  a 
  careful 
  

   search 
  was 
  made, 
  which 
  resulted 
  in 
  the 
  discovery 
  of 
  two 
  localities 
  

   in 
  which 
  the 
  limestone 
  was 
  almost 
  unaltered, 
  being 
  very 
  tine 
  in 
  

   grain 
  and 
  blue 
  in 
  color, 
  and 
  bearing 
  a 
  strong 
  resemblance 
  to 
  the 
  

   limestones 
  of 
  more 
  recent 
  formations. 
  In 
  such 
  case 
  the 
  blue 
  

   limestone 
  is 
  interstratified 
  with 
  the 
  ordinary 
  white 
  coarse-grained 
  

   marble 
  of 
  the 
  Grenville 
  series 
  and 
  passes 
  into 
  it, 
  there 
  being 
  

   evidently 
  portions 
  of 
  the 
  limestones 
  which 
  have 
  escaped 
  meta- 
  

   morphism. 
  These 
  occurrences 
  serve 
  to 
  dispose 
  of 
  any 
  lingering 
  

   doubts 
  concerning 
  the 
  sedimentary 
  origin 
  of 
  the 
  limestone 
  in 
  

   question." 
  

  

  Silurian 
  fossils 
  were 
  discovered 
  about 
  six 
  miles 
  from 
  Canter- 
  

   bury 
  station 
  of 
  the 
  St. 
  Andrews 
  and 
  Woodstock 
  branch 
  of 
  the 
  

   Canadian 
  Pacific 
  Railway, 
  in 
  a 
  belt 
  of 
  rocks 
  lying 
  northwest 
  of 
  

   the 
  granite 
  area 
  in 
  western 
  York. 
  The 
  rocks 
  in 
  question 
  have 
  

   hitherto 
  been 
  classified 
  as 
  Cambro-Silurian. 
  They 
  are 
  partially 
  

   altered 
  gray 
  slates. 
  The 
  fossils, 
  according 
  to 
  Dr. 
  Ami, 
  indicate 
  

   uppermost 
  Silurian. 
  

  

  Along 
  the 
  shore 
  of 
  Grand 
  Manitoulin 
  Island, 
  Lake 
  Huron, 
  a 
  

   coralline 
  limestone 
  containing 
  Lower 
  Niagara 
  fossils 
  is 
  reported 
  

   by 
  Dr. 
  Ami. 
  

  

  P'^oot-prints 
  of 
  Hylopus 
  and 
  Sauropus, 
  and 
  other 
  evidences 
  of 
  

   Carboniferous, 
  have 
  been 
  reported 
  from 
  the 
  fossiliferous 
  strata 
  

   alonsj 
  the 
  north 
  shore 
  of 
  the 
  Basin 
  of 
  oVIinas. 
  

  

  "The 
  bone-beds 
  of 
  McAra 
  Brook, 
  holding 
  crustacean 
  and 
  fish 
  

   remains, 
  were 
  again 
  examined 
  and 
  additional 
  examples 
  were 
  

   obtained 
  of 
  a 
  J^leraspis, 
  which 
  appears 
  to 
  be 
  new 
  (tlie 
  genus 
  hav- 
  

   ing 
  been 
  identified 
  by 
  Dr. 
  A, 
  S. 
  Woodward), 
  and 
  fragments 
  of 
  

   cephalaspidian 
  and 
  acanthodian 
  species,

  of
