  The 
  well 
  from 
  which 
  (3) 
  was 
  taken 
  is 
  about 
  1500 
  feet 
  from 
  

   Oak 
  Orchard 
  creek, 
  with 
  the 
  ground 
  surface 
  only 
  a 
  few 
  feet 
  above 
  

   the 
  water 
  level 
  in 
  the 
  creek. 
  The 
  elevation 
  of 
  water 
  in 
  Oak 
  

   Orchard 
  creek 
  directly 
  opposite 
  is 
  substantially 
  the 
  same 
  as 
  in 
  

   the 
  well, 
  and 
  when 
  pumping 
  from 
  the 
  well 
  the 
  water 
  is 
  drawn 
  to 
  

   about 
  5 
  feet 
  below 
  the 
  level 
  of 
  the 
  water 
  in 
  the 
  creek. 
  Neverthe- 
  

   less, 
  analyses 
  (3) 
  and 
  (4) 
  show 
  that 
  the 
  quality 
  of 
  water 
  in 
  the 
  

   well 
  is 
  quite 
  different 
  from 
  that 
  in 
  the 
  creek. 
  In 
  the 
  case 
  of 
  the 
  

   water 
  from 
  the 
  well, 
  permanent 
  hardness 
  is 
  only 
  4°, 
  while 
  the 
  

   water 
  from 
  the 
  creek 
  shows 
  17°, 
  although 
  it 
  is 
  difficult 
  to 
  under- 
  

   stand, 
  under 
  the 
  conditions, 
  how 
  the 
  source 
  of 
  water 
  in 
  the 
  well 
  

   can 
  be 
  other 
  than 
  that 
  from 
  the 
  creek 
  — 
  the 
  more 
  specially 
  since 
  

   the 
  underlying 
  rock 
  is 
  open. 
  In 
  regard 
  to 
  the 
  permanent 
  hard- 
  

   ness 
  of 
  the 
  creek 
  water, 
  as 
  shown 
  by 
  analysis 
  (4), 
  it 
  is 
  probably 
  

   due 
  to 
  Oak 
  Orchard 
  creek 
  flowing 
  over 
  a 
  bed 
  of 
  gypsum 
  near 
  

   Oakfield. 
  

  

  Quality 
  of 
  Water 
  in 
  the 
  Vicinity 
  of 
  Batavia 
  

  

  In 
  order 
  to 
  still 
  further 
  illustrate 
  water 
  supplies 
  in 
  western 
  

   New 
  York, 
  the 
  following 
  analyses 
  from 
  the 
  vicinity 
  of 
  Batavia, 
  

   as 
  made 
  by 
  Mr 
  Eilinger, 
  are 
  of 
  interest; 
  (1) 
  is 
  from 
  Devil's 
  lake, 
  

   a 
  small 
  body 
  of 
  water 
  ten 
  or 
  twelve 
  miles 
  west 
  of 
  Batavia; 
  (2) 
  is 
  

   from 
  Mill 
  springs, 
  five 
  miles 
  north 
  of 
  Batavia; 
  (3) 
  is 
  from 
  Ham- 
  

   ilton 
  springs, 
  two 
  miles 
  south 
  of 
  Batavia; 
  and 
  (4) 
  is 
  from 
  Horse- 
  

   shoe 
  lake, 
  two 
  and 
  one-half 
  miles 
  east 
  of 
  Batavia. 
  Mill 
  springs, 
  

   the 
  analysis 
  of 
  which 
  contains 
  the 
  most 
  total 
  hardness, 
  are 
  at 
  the 
  

   foot 
  of 
  a 
  ridge 
  from 
  100 
  to 
  150 
  feet 
  in 
  night 
  and 
  probably 
  is 
  not 
  

   far 
  from 
  the 
  gypsum 
  belt, 
  as 
  the 
  permanent 
  hardness 
  in 
  this 
  water 
  

   is 
  difficult 
  to 
  account 
  for 
  on 
  any 
  other 
  basis. 
  Both 
  Hamilton 
  

   springs 
  and 
  Horseshoe 
  lake 
  are 
  above 
  that 
  belt, 
  and 
  accordingly 
  

   permanent 
  hardness 
  is 
  not 
  very 
  serious 
  in 
  either 
  of 
  them.
