trusted,  it  was  a  tough  red-brown  marlstone  crowded  with  oolitic 
grains  of  iron.  I  suspect,  however,  that  this  sample  has  been  mis¬ 
placed,  and  that  the  hard  rock  was  really  a  calcareous  sandstone. 
As  soon  as  this  was  pierced,  water  came  up  with  a  rush,  bringing 
up  at  first  large  quantities  of  sand,  but  gradually  clearing  to  a  strong, 
steady  flow  of  4619  gallons  per  hour,  the  water  rising  to  more  than 
30  feet  above  the  surface  of  the  ground.

§  2.  The  Borixg  at  Aleord  (1889). 
Alford  lies  2|  miles  north  of  Willoughby,  and  it  is  consequently 
very  interesting  to  have  proof  of  the  existence  of  Lower  Cretaceous 
strata  at  no  great  depth  beneath  this  place.  The  boring  was  made 
in  1889  at  the  Alford  Grammar  School,  and  the  results  were  commu¬ 
nicated  to  me  by  Mr.  Eardley  Mason,  one  of  the  Governors  of  the 
School.  I  have  also  to  thank  him  for  sending  me  samples  of  the 
different  beds,  the  details  which  follow  being  largely  obtained  by 
examination  of  these  samples.
