ROLLED  STONES  AT  HIGH  LEVELS  IN  JERSEY.

10  to  15  feet  thick.  The  clay  is  very  considerably  thicker  here, 
but  the  road  and  the  bank  below  prevent  its  lower  part  from  being 
seen.  Along  the  top  of  this  section,  not  far  from  the  surface  of  the 
ground — in  fact,  in  some  places  close  up  to  the  vegetable  soil — 
there  is  a  layer  of  small  rounded  pebbles  thickly,  though  not  closely, 
scattered  through  some  .3  or  4  feet  of  the  clay.  These  pebbles 
vary  from  about  1  to  3  inches  in  diameter,  and  they  appear  to  be 
all  of  rhyolite  or  granite,  like  those  on  the  present  beach  close  by. 
This  bed  is  perhaps  from  40  to  50  feet  above  spring-tide  level. 
Farther  along  the  coast  small  round  pebbles  are  frequently  met 
with  in  the  clay,  but  generally  at  lower  levels. 
On  the  southern  coast,  a  little  north  of  Millbrook,  on  a  roadside 
just  below  the  shoulder  of  the  slope  down  from  the  inland  high 
plateau,  I  found  a  subangular  piece  of  coarse  granite  about  6x9 
inches  in  size  embedded  in  small  shale-rubble  below  about  4  feet 
of  clay.  A  little  higher  up  the  road,  on  the  top  of  the  plateau 
(which  is  here,  perhaps,  a  little  more  than  100  feet  above  high- 
water  spring  tide),  there  is  exposed  a  bed  of  small  round  pebbles, 
mostly  of  fine  diorite  and  greenstone  (?),  but  among  them  are  some 
of  granite,  of  hardened  shale  (?),  and  one  or  two  of  flint.  This 
bed  is  about  200  feet  long,  and  lies  beneath  some  3  or  4  feet  of 
brick-clay.  The  rock  below,  which  is  not  seen  at  this  point,  is 
shale.  The  bed  is  about  |  of  a  mile  from  the  coast.  As  I  am, 
however,  unable  to  exclude  the  possibility  of  artificial  introduction 
here,  this  bed  cannot  be  brought  forward  as  evidence  with  entire 
confidence. 
About  1  mile  farther  west,  behind  the  village  of  Beaumont,  where 
the  widening  of  a  road  had  laid  bare  some  7  feet  of  clay,  I  found 
a  smoothly-rounded  piece  of  granite  measuring  5x4  inches,  some 
4  feet  beneath  the  surface.  Other  rounded  pieces  of  about  the 
same  size  were  lying  about,  probably  derived  from  the  same  source. 
The  underlying  rock  is  shale,  and  the  nearest  granite  is  about  1  mile 
farther  west,  with  two  intervening  valleys.  The  roadside  where 
this  stone  was  found  is  500  or  600  yards  from  the  shore,  and  it  is 
perhaps  30  or  40  feet  above  spring-tide  mark.  This  estimate  of 
level,  however,  is  a  mere  guess.  At  several  other  places  on  the 
south  and  east  coasts  I  have  found  rolled  stones  under  or  in  the 
clay,  at  from  40  to  50  feet  above  the  spring-tide  mark.  Unfortu¬ 
nately,  I  have  never  had  time  to  examine  the  more  distant  western 
and  northern  parts  of  the  coast ;  but  the  raised  beach  mentioned 
by  Mr.  Danby,  already  alluded  to,  is  on  the  west  coast,  and  recently 
a  writer  in  the  4  Jersey  Times  ’  described  one,  said  to  be  about 
30  feet  above  6  sea-level,’  at  Greve-au-Lancon,  near  the  extreme 
north-western  corner  of  the  island.  Very  probably  a  careful  search 
would  lead  to  the  discovery  of  others. 
Rolled  stones  have  not  only  been  found  near  the  coast,  they  have 
also  been  discovered  on  the  high  ground  in  the  interior  of  the 
island ;  but,  as  I  did  not  actually  pick  them  out  of  the  clay  myself,  I 
cannot  bring  them  forward  as  evidence  with  the  same  confidence  as 
if  I  had  seen  them  in  situ.  There  is  no  reason,  however,  to  doubt
