  probably 
  be 
  included 
  in 
  the 
  Calciferous 
  

   group,

  all

  may 
  be 
  referred 
  to 
  the 
  Potsdam

  this

  a 
  very 
  rapid 
  increase 
  in

  of

   these

  in 
  their 
  southward 
  extension, 
  over 
  what 
  they 
  attain 
  

   in

  they

  The 
  principal 
  flow 
  of 
  water 
  was 
  from 
  No. 
  12, 
  and 
  it 
  rose 
  within 
  

  

  16 
  feet 
  of 
  the 
  surface 
  until 
  the 
  well 
  was 
  tubed, 
  when 
  it 
  overflowed 
  

  

  the 
  surface, 
  yielding 
  about 
  36 
  barrels 
  per 
  day. 
  The 
  quality 
  of 
  the 
  

   water 
  is 
  not 
  given. 
  No. 
  5 
  is 
  described 
  in 
  the 
  published 
  section 
  as 
  

   Calciferous, 
  but 
  it 
  probably 
  includes 
  nearly 
  or 
  quite 
  '200

   properly 
  belongs 
  to 
  the 
  Potsdam

  The 
  similarity 
  in 
  the 
  litli- 
  

   ological 
  character 
  of 
  the 
  beds 
  composing 
  these 
  two 
  groups 
  is 
  such 
  

   that 
  it 
  is 
  impossible 
  to 
  determine, 
  from 
  the 
  material 
  brought 
  Up 
  from 
  

   an 
  ordinary 
  boring, 
  where 
  the 
  stratum 
  belongB, 
  and 
  the 
  thickness 
  of 
  

   the 
  Calciferous 
  must 
  he 
  determined 
  by 
  its 
  general 
  average 
  :it

   localities. 
  

  

  The 
  St.

  sandstone, 
  and 
  the 
  white 
  sandstone 
  of 
  the 
  Cal- 
  

   ciferous 
  group, 
  were 
  both 
  found 
  to 
  lie 
  water-bearing

  the 
  Btreator

  the 
  Calciferous 
  within 
  about

  feet, 
  and 
  the 
  

  

  water 
  was 
  reported 
  to 
  be 
  sweet 
  and 
  apparently 
  free 
  from 
  deleterious 
  

  

  mineral 
  suhstances. 
  The 
  water
