yards  of  calcareous  rock  much  ‘  troubled  ’  and  quartz-veined  on  the 
southern  side,  and  this  was  succeeded  by  a  fair  thickness  of  Jurassic 
rock  with  ‘knots,'*  ‘  prisms/  plenty  of  belemnites,  and  traces  of  other 
fossils.  Then,  after  a  short  interval,  we  found  the  black-garnet 
rock,1  in  places  much  crushed.  Interruptions  of  turf  and  debris  now 
became  frequent,  but  in  a  ravine,  rather  above  us  on  the  right, 
Mr.  Eccles  (while  I  was  working  in  another  direction)  found  out¬ 
crops  both  of  disthene-schist  and  of  rauchwacke.  After  this  we 
passed  some  more  outcrops  of  schist  and  a  little  rauchwacke,  but  the 
exposures  now  became  few  till  we  joined  our  morning’s  track  at  the 
foot  of  the  steeper  slopes.

Xote. — The  folds  and  faults  in  the  above  diagrammatic  sections  are  to  a 
great  extent  hypothetical,  but  the  general  correspondence  of  the  several  parts 
of  the  two  sections  can  be  made  out  with  tolerable  certainty  on  the  ground, 
without  actually  traversing  the  intervening  space.  The  line  followed  in  the 
first  part  of  the  ascent  did  not  take  Mr.  Eccles  and  myself  over  good  outcrops, 
and  we  are  not  quite  satisfied  about  those  mai’ked  a,  though  we  believe  them  to 
be  right.  At  the  top  of  the  pass,  just  behind  the  line  of  section,  some  Jurassic 
rock  occurs. 
The  above  sections,  though  only  a  diagrammatical  record  of  our  ob¬ 
servations,  may  make  the  preceding  description  more  intelligible.  I 
believe  them  to  be  generally  correct,  but  cannot  vouch  for  the  relative 
1  The  garnets  are  sometimes  so  well  cleaved  that  one  can  remove  them  in 
slices.  Here  and  there,  owing  to  the  crushing,  the  schist  is  difficult  to  distinguish 
from  the  Jurassic  rock.  But  these  puzzles  are  only  local,  and  are  got  rid  of  by 
making  a  ‘  cast  ’  or  two  in  the  neighbourhood.
