RECENT  BORINGS  IN  EAST  LINCOLNSHIRE.  [Allg.  1 893. 
Office  for  reference.  When  the  ground  was  surveyed,  the  existence 
of  an  anticlinal  along  the  eastern  margin  of  the  Wolds  was  suspected, 
hut  it  was  not  until  the  borings  now  described  had  been  made  that 
Mr.  Jukes-Browne  felt  justified  in  indicating  on  the  map  this  large 
tract  of  Lower  Cretaceous  rocks.  A  knowledge  of  the  structure  of 
the  Drift- covered  region  was  of  some  importance  in  respect  to  water- 
supply.  The  most  promising  water-bearing  stratum  was  the  Spilsby 
Sandstone.  A  few  years  ago  this  bed  was  tapped  by  a  boring  at 
Skegness,  but  proved  thin  and  compact.  At  Willoughby,  however, 
it  was  loose,  and  yielded  such  a  supply  as  might  have  been  antici 
pated.  The  speaker  agreed  with  Mr.  Jukes-Browne’s  interpretation 
of  the  structure  of  the  district.
