The  information  on  which  this  communication  is  based  has  been  in 
my  possession  since  1889,  but  pressure  of  other  work  had  prevented 
me  from  preparing  it  for  publication  until  the  present  time. 
The  results  of  the  borings  which  are  here  described  are  important, 
because  they  give  information  concerning  the  geological  structure  of 
the  platform  which  underlies  the  Glacial  Drift  on  the  eastern  side  of 
the  southern  part  of  the  Lincolnshire  Wolds.  We  learn  from  them 
that  the  outcrop  of  the  Lower  Cretaceous  sands  and  clays  extends 
much  farther  northward  beneath  the  Drift  on  this  side  of  the 
Wolds  than  there  was  any  reason  to  suspect  at  the  time  when 
I  mapped  the  area  for  the  Geological  Survey.

§  1.  The  Boring  at  Willoughby  (1887). 
Willoughby  is  a  village  between  the  towns  of  Burgh  and  Alford, 
and  the  site  of  the  boring  is  at  the  station  on  the  East  Lincoln¬ 
shire  Railway,  which  is  the  junction  for  the  new  branch-line 
to  Sutton.  The  boring  was  made  for  the  Railway  Company  in 
1887,  and  a  good  supply  of  water  was  procured  at  a  depth  of 
245  feet. 
Eor  information  regarding  the  beds  passed  through  I  am  in¬ 
debted,  in  the  first  place,  to  Mr.  H.  Cheetham,  the  engineer  of  the 
railway ;  but  the  description  of  the  strata  furnished  by  him  being 
only  a  well-sinker’s  account,  and  not  sufficiently  accurate  to  enable 
me  to  identify '  the  strata,  I  wrote  to  my  friend,  Mr.  Meaburn 
Staniland,  E.G.S.,  asking  if  he  could  take  an  opportunity  of  looking 
over  the  samples  of  the  cores  which  were  preserved  in  the  Engi¬ 
neer’s  office  at  Louth,  and  access  to  which  was  most  kindly  promised 
by  Mr.  Cheetham.  This  Mr.  Staniland  was  good  enough  to  do,  and 
it  is  mainly  from  his  description  of  the  samples  and  from  the  sight 
of  very  small  pieces  of  one  or  two  of  them  that  the  following  account 
has  been  drawn  up  ;  but  the  thicknesses  of  the  several  beds  are,  of 
course,  taken  from  the  particulars  supplied  by  Mr.  Cheetham. 
The  boring  commenced  in  the  Boulder  Clay  shown  on  the  Geo¬ 
logical  Survey  Map  (Sheet  84)  as  occurring  at  that  spot,  and  this
