526  DR.  A  DUNLOP  ON  RAISED  REACHES  AND  [Xov.  1 893', 
stones  are  also  to  be  observed.  The  bottom  of  this  cutting  is  about 
20  feet  above  spring-tide  higb-water  mark,  and  not  more  than 
100  feet  from  the  shore. 
About  600  yards  farther  inland,  and  nearly  in  a  line  with  the 
South  Hill  cutting,  the  Jersey  Eastern  Railway  is  carried  through 
the  rock  at  the  base  of  the  eastern  side  of  the  main  hill  under 
Port  Regent.  This  cutting  shows  a  section  of  the  brick-clay 
about  100  feet  long,  and  perhaps  6  or  7  feet  thick,  which  rests  on 
hard  undecomposed  granite.  Passing  along  this  deposit  almost 
horizontally,  and  mostly  at  a  height  of  about  1  foot  above  the 
rock,  is  an  irregular  layer  of  well-rounded  pebbles ;  others  are 
scattered  about  beneath  the  main  layer,  some  resting  on  the  sub¬ 
jacent  rock,  and  there  are  also  rounded  stones  and  angular  fragments 
here  and  there  in  the  clay  above  it.  The  height  of  this  bed  above 
spring-tide  high-water  level  is  perhaps  50  feet,  or  a  little  more. 
About  2  miles  east  of  St.  Helier  one  of  the  main  roads  is 
carried  through  a  low  ridge  near  St.  Clement’s  Church,  and  as  it 
slopes  gently  up  the  western  side  it  cuts  through  an  interesting 
‘  beach  ’  with  its  overlying  clay  and  angular  fragments.  The  best 
section  is  that  on  the  northern  side  of  the  road,  though  it  is  now 
too  much  covered  with  ivy  and  grass  to  be  well  seen.  At  its  upper 
or  eastern  end  there  is  a  steep  slope  of  decomposing  diorite,  which 
passes  westward  and  downward,  under  the  layer  of  rolled  stones. 
Covering  this  sloping  rock  and  old  beach  is  a  bed  of  brick-earth, 
varying  from  a  few  feet  to  15  feet  in  thickness,  according  to  the 
slope  of  the  ground  above  and  that  of  the  rock  and  beach  below.  The 
pebbles  of  the  raised  beach — mostly  a  few  inches  in  longest  diameter, 
though  some  are  much  bigger — are  of  fine  red  granite  and  of 
diorite,  those  of  granite  considerably  predominating.  In  the  brick- 
earth  a  short  distance  above  the  rounded  pebbles — generally  about 
2  or  3  feet — is  a  straggling  layer  of  angular  pieces  of  fine  red 
granite.  These  fragments  are  chiefly  from  1  or  2  to  6  or  8  inches 
in  greatest  length,  but  near  the  lowest  and  most  westerly  part  of 
the  section  there  is  a  sharpty  angular  block,  the  projecting  sides  of 
which  measure  1  ft.  4  in.,  1  ft.  2  in.,  and  2  ft.  7  in.  respectively. 
As  before  mentioned,  the  underlying  rock  is  diorite,  while  the 
nearest  observable  outcrop  of  granite  is  440  feet  to  the  eastwaid 
of  this  block,  and  some  20  or  30  feet  above  its  level,  on  the  top  of 
the  ridge.  The  average  height  of  this  beach  is  about  50  to  60  leet, 
or  perhaps  a  little  more,  above  spring-tide  high  water,  and  it  is  600 
yards  distant  from  the  nearest  part  of  the  seashore. 
About  1  mile  to  the  east  of  St.  Clement’s  Church,  near  the 
same  main  road,  a  small  hollow  or  rather  cleft  in  the  rock  (here 
a  fine-grained  red  granite),  at  about  the  same  level  as  the  lower  part 
of  the  raised  beach  last  described,  is  filled  with  small,  well-rounded 
stones,  mostly  diorite.  It  looks  like  the  remaining  fragment  of  a 
larger  beach,  saved  by  its  protected  position  from  being  carried 
away  with  the  rest. 
On  the  eastern  coast  of  the  island,  near  Anne  Port,  a  road- 
gide-cutting  shows  a  section  of  clay  about  100  feet  long,  and  from
