  parts 
  

   vvhere 
  the

  and 
  in 
  the

  co. 
  on 
  the 
  hillside 
  to 
  the 
  south 
  of 
  

   Stony 
  creek 
  which 
  it 
  follows 
  to 
  near 
  its 
  head 
  when 
  it 
  turns 
  to 
  

   the 
  north 
  and 
  circles 
  around 
  the 
  upper 
  part 
  of 
  Bradt 
  hill 
  and 
  

   then 
  runs 
  southeasterly 
  into 
  the 
  northeastern 
  part 
  of 
  Rensselaer- 
  

   ville 
  township. 
  The 
  lowest 
  heavy 
  line 
  of 
  the 
  reds 
  which 
  is 
  called 
  

   the 
  base 
  of 
  the 
  Oneonta 
  formation 
  follows 
  a 
  nearly 
  parallel 
  

   course 
  though 
  somewhat 
  farther 
  to 
  the 
  south 
  and 
  west 
  than 
  the 
  

   Hamilton-Sherburne 
  line. 
  

  

  Rensselaerville 
  

  

  Rensselaerville 
  lies 
  to 
  the 
  south 
  of 
  the 
  western 
  half 
  of 
  Berne, 
  

   forming 
  the 
  southwestern 
  township 
  of 
  Albany 
  co. 
  It 
  is 
  

   bounded 
  on 
  the 
  east 
  by 
  Westerlo 
  township,' 
  on 
  the 
  south 
  by 
  

   Greene 
  co. 
  and 
  on 
  the 
  west 
  by 
  Schoharie. 
  Its 
  surface 
  is 
  

   mostly 
  high 
  land 
  forming 
  either 
  a 
  part 
  of 
  the 
  Helderberg 
  plateau 
  

   or 
  the 
  northeastern 
  Catskills. 
  Its 
  principal 
  streams 
  are 
  the 
  

   Catskill 
  creek 
  which 
  flows 
  across 
  the 
  southwestern 
  part 
  receiv- 
  

   ing 
  the 
  Potter 
  hollow 
  branch 
  from 
  the 
  west, 
  b'oth 
  streams 
  flanked 
  

   by 
  high 
  and 
  steep 
  hills, 
  and 
  Tenmile 
  creek 
  which 
  flows 
  in 
  a 
  

   southerly 
  direction 
  across 
  the 
  eastern 
  part 
  of 
  the 
  township 
  re- 
  

   ceiving 
  Eightmile 
  creek 
  from 
  the

  and 
  enters 
  the 
  

   Catskill 
  creek 
  below

  in

  co. 
  About 
  one 
  mile 
  

   west 
  of

  creek 
  is 
  a 
  brook 
  which 
  flows 
  parallel 
  to 
  it 
  across 
  

   the 
  southern 
  half 
  of 
  the 
  township, 
  entering 
  the 
  Catskill 
  creek 
  at 
  

   Oakhill, 
  which 
  may 
  be 
  called 
  the 
  Oakhill 
  brook. 
  

  

  A 
  striking 
  characteristic 
  of 
  many 
  of 
  the 
  hills 
  in 
  this 
  and 
  other 
  

   townships 
  of 
  the 
  Helderberg 
  region 
  is 
  the 
  steep 
  northern 
  slope 
  

   and 
  the 
  gradual 
  descent 
  to 
  the 
  south 
  due 
  to 
  the 
  strong 
  dip 
  in: 
  

   that 
  general 
  direction. 
  An 
  excellent 
  illustration 
  is 
  afforded 
  by 
  

   the 
  ridge 
  to 
  the 
  east 
  of 
  Rensselaerville 
  which 
  ends 
  very 
  abruptly 
  

   on 
  the 
  north 
  and 
  slopes 
  gradually 
  to 
  the 
  south.- 
  The 
  steep- 
  

   northern 
  end 
  of 
  this 
  hill 
  is 
  clearly 
  defined 
  from 
  the 
  top 
  of 
  Agrippa
