ME.  A.  J.  JTJKES-BROWNE  ON  SOME  RECENT  [Aug.  1 893, 
at  Martin,  about  10  miles  south-east  of  Lincoln.  See  4  Geology 
of  the  Country  around  Lincoln,’  Geol.  Survey  Mem.  sh.  83  (1888), 
p.  137. 
Becurring  to  the  well  at  Mr.  Soulby’s,  no  record  of  thickness  was 
kept  by  the  well-sinkers  below  the  base  of  the  chalk-mass ;  but 
Mr.  Eardley  Mason  informs  me  that  he  watched  the  boring  while  it 
was  being  made,  and  he  believes  it  was  carried  to  a  depth  of 
about  200  feet,  chiefly  through  blue  and  grey  clays.  Some  of 
these  clays  were,  he  says,  like  those  of  the  Grammar  School  boring, 
but  the  lowest  he  saw  was  dark  and  shaly  like  Kimeridge  Clay.  He 
believes  the  chalk  was  underlain  by  gravel  and  sand,  and  that  the 
rest  of  the  depth  was  clay.  No  water  having  been  found,  the 
boring  was  abandoned  and  the  hole  plugged  up  to  the  base  of  the 
chalk,  as  in  the  case  of  the  more  recent  boring.  If  the  Brewery 
boring  was  carried  to  200  feet,  it  must  have  been  abandoned  when 
another  35  or  40  feet  would  have  taken  them  into  the  Spilsby  Sand¬ 
stone,  and  doubtless  have  secured  as  good  a  supply  of  water  as  at 
Willoughby. 
§  3.  The  Torino  at  Skegness  (1886). 
In  the  4  Geology  of  East  Lincolnshire  ’  (Appendix  B,  p.  168)  parti¬ 
culars  were  given  of  a  deep  boring  at  the  Skegness  Waterworks ;  but 
it  seems  that  two  borings  were  made  at  these  works,  one  of  them 
not  being  carried  beyond  130 1  feet,  while  the  second  was  carried  to 
over  400  feet. 
The  details  which  follow  have  been  obtained  from  Mr.  Crauford, 
the  foreman  in  charge  of  the  boring  ;  and  they  were  communicated  to 
me  by  my  colleague  Mr.  W.  Whitaker,  E.B.S.  They  differ  in  some 
important  particulars  from  the  account  given  in  the  Survey  Memoir, 
and  consequently  it  seems  desirable  to  publish  them  for  comparison 
with  that  account  and  with  the  Willoughby  boring,  Skegness  being 
only  7|  miles  south-east  of  Willoughby.
