character,  they  are  here  referred,  and  the  apparent  inferior  position  of 
the  Devonian  is  supposed  to  be  due  to  a  dislocation.  Accidental  inter- 
calations of  Upper  Silurian  and  Kingston  strata  are  found. 
Bailey,31  in  1872,  describes  the  rocks  of  the  greater  part  of  Grand 
Manan  as  consisting  of  Triassic  trap.  Upon  its  east  side  are,  however, 
found  metamorphic  rocks,  which  may  belong  to  different  series ;  but 
none  are  believed  to  be  more  recent  than  the  earliest  Primordial 
Silurian,  while  some  of  them  may  be  Huronian. 
Matthew  and  Bailey,32  in  1876,  place  the  Mascarene  and  Kingston 
series,  the  latter  of  which  was  previously  considered  Upper  Huronian, 
in  the  Upper  Silurian  upon  account  of  fossils  discovered  in  them. 
Bailey  and  Matthew,33  assisted  by  Ells,  in  1877,  in  observations 
on  southern  New  Brunswick,  provisionally  refer  the  Ooldbrook  group, 
formerly  considered  as  Laurentian,  to  the  Huronian.  The  granites  are 
separated  from  the  stratified  formations  of  the  Coldbrook  group. 
Matthew,34  in  1878,  refers  as  doubtfully  belonging  to  the  Laurentian 
the  slate  formation  of  Charlotte  county,  formerly  described  as  Coastal 
rocks  and  placed  in  the  Huronian.  In  the  Kingston  series,  more  recent 
jhan  the  Coastal,  are  rather  crystalline  rocks  which  are  believed  in  part 
:o  belong  to  the  Upper  Silurian,  but,  like  the  Coastal  rocks,  are  of  un- 
certain age.  The  crystalline  mica-schists,  hornblende- schists,  gneisses, 
liorites,  etc.,  of  Grand  Manan  combine  in  characters  the  two  belts  of 
Kingston  rocks  and  those  of  certain  Upper  Silurian  strata. 
Bailey  and  Ells,35  in  1878,  find  in  the  Caledonia  mountains  of  Albert 
uid  Westmoreland  counties  chloritic  and  talcose  slates  associated  with 
>eds  of  grit  and  conglomerate,  which  are  regarded  as  probably  of  Hu- 
onian  age. 
Ells,36  in  1879,  finds  in  Albert,  eastern  Kings,  and  St.  Johns  counties 
►re-Silurian  rocks,  which  are  placed  in  the  Huronian  and  Laurentian. 
?he  older  series  is  said  to  consist  of  syenite,  felsites,  feldspathic  quartzites, 
,nd  limestones.  In  many  places  are  transitions  from  the  slates  through 
chists,  felsites,  and  gneisses,  to  syenites.  The  newer  series  consists 
f  felsitic,  siliceous,  brecciated,  and  ash  rocks  at  the  base,  with  talcose, 
hloritic,  and  older  schists,  ash  rocks  and  purple  grits,  and  conglom- 
rates.  The  second  group  lies  unconformably  upon  the  rocks  of  the  first. 
Bailey,37  in  1879,  divides  the  pre- Silurian  rocks  of  southern  New 
frunswick  into  four  divisions  on  lithological  grounds.  The  first  are 
yenitic,  feldspathic,  and  gneissic  rocks;  the  second,  limestones  and 
olomites,  with  others.  These  two  divisions  are  regarded  as  belonging 
o  the  Laurentian.  The  third  is  a  felsite-petrosilex  group  which  com- 
|rises  sandstones  and  conglomerates,  as  well  as  amygdaloid al  ash  rocks 
!nd  ash  conglomerates.  This  is  the  <  -oldbrook  group  of  the  earlier  re- 
jorts  and  is  regarded  as  a  lower  member  of  the  Huronian  system.  The 
i)iirth  division  is  a  schistose,  chloritic,  and  micaceous  group,  comprising 
inong  other  rocks  conglomerates,  clay  slates,  quartzites,  ash  rocks, 
mygdaloids,  etc*,  and  is  regarded  as  the  upper  member  of  the  Huro-
