  drumlins 
  are 
  conspicuous 
  for 
  groups 
  of 
  large 
  boulders 
  turned 
  on 
  

   their 
  eastern 
  slopes. 
  The 
  axis 
  of 
  the 
  drumlins 
  is 
  in 
  a 
  way 
  east- 
  

   west 
  but 
  within 
  the 
  field 
  of 
  the 
  Sacandaga 
  glacier 
  some 
  of 
  them 
  

   tend 
  towards 
  the 
  northeast-southwest 
  direction 
  as 
  do 
  the 
  drumlin- 
  

   oid 
  forms 
  about 
  Mayfield. 
  Thus 
  the 
  drumlins 
  and 
  drumlinoids 
  

   fall 
  into 
  perfect 
  harmony 
  in 
  direction 
  of 
  trend 
  with 
  the 
  glacial 
  

   striae. 
  The 
  till 
  of 
  many 
  of 
  these 
  drumlins 
  is 
  comparatively 
  light 
  

   and 
  sandy 
  but 
  this 
  may 
  be 
  said 
  also 
  of 
  the 
  ground 
  moraine 
  in 
  gen- 
  

   eral 
  in 
  the 
  vicinity 
  of 
  the 
  crystalline 
  rocks. 
  Indeed 
  the 
  ground 
  

   moraine 
  everywhere 
  in 
  the 
  region 
  follows 
  the 
  usual 
  law 
  of 
  glacial 
  

   deposits 
  in 
  showing 
  the 
  close 
  kinship 
  to 
  the 
  bed 
  rocks 
  from 
  which 
  

   it 
  has 
  been 
  so 
  largely 
  derived. 
  This 
  has 
  a 
  conspicuous 
  bearing 
  on 
  

   the 
  agriculture 
  of 
  the 
  region 
  and 
  it 
  will 
  be 
  found, 
  for 
  example, 
  that 
  

   the 
  drift 
  around 
  Johnstown 
  partakes 
  especially 
  of 
  the 
  character 
  of 
  

   the 
  underlying 
  black 
  shales 
  and 
  the 
  soils 
  are 
  consequently 
  rich 
  and 
  

   the 
  region 
  agriculturally 
  prosperous. 
  A 
  similar 
  belt, 
  productive 
  for 
  

   the 
  same 
  reason, 
  is 
  found 
  south 
  of 
  the 
  Mohawk 
  river 
  for 
  a 
  width 
  

   of 
  4 
  or 
  5 
  miles 
  in 
  the 
  vicinity 
  of 
  Scotch 
  Church, 
  Minaville 
  and 
  

   Glenville. 
  On 
  the 
  higher 
  sandstone 
  hills 
  the 
  drift, 
  as 
  already 
  in- 
  

   dicated, 
  is 
  not 
  only 
  thin 
  but 
  partakes 
  of 
  the 
  poverty 
  of 
  the 
  sand- 
  

   stones 
  so 
  far 
  as 
  its 
  productive 
  capacity 
  is 
  concerned. 
  

  

  Lake 
  deposits. 
  Some 
  of 
  the 
  most 
  interesting 
  accumulations 
  of 
  

   the 
  district 
  were 
  made 
  in 
  standing 
  water. 
  These 
  include 
  small 
  

   areas 
  of 
  high 
  level 
  sands, 
  evidently 
  in 
  pools 
  or 
  lakelets 
  sustained 
  

   by 
  retaining 
  walls 
  of 
  ice. 
  An 
  example 
  of 
  this 
  is 
  found 
  west 
  of 
  

   Hagadorn's 
  Mills, 
  a 
  tablelike 
  deposit 
  which 
  has 
  been 
  cut 
  in 
  two 
  by 
  

   the 
  waters 
  of 
  the 
  Kenneatta. 
  Another 
  of 
  these 
  level 
  sand 
  deposits 
  

   likewise 
  dissected 
  by 
  a 
  stream, 
  is 
  found 
  southwestward 
  from 
  Bene- 
  

   dict 
  and 
  another 
  conspicuous 
  example 
  lies 
  just 
  westward 
  from 
  Edin- 
  

   burg. 
  In 
  the 
  eastern 
  part 
  of 
  Gloversville 
  is 
  an 
  area 
  of 
  flat 
  or 
  gentle 
  

   sloping 
  sands 
  or 
  clays 
  which 
  are 
  doubtfully 
  interpreted 
  as 
  deposits 
  

   of 
  a 
  lake 
  surrounded 
  by 
  a 
  glacial 
  moraine 
  and 
  waning 
  glacial 
  ice. 
  

  

  Deposits 
  of 
  Lake 
  Sacandaga. 
  This 
  name 
  is 
  given 
  to 
  a 
  body 
  of 
  

   water 
  which 
  evidently 
  occupied 
  the 
  depression 
  now 
  known 
  as 
  the 
  

   Great 
  Vly. 
  Its 
  water 
  was 
  apparently 
  held 
  in 
  place 
  by 
  the 
  massive 
  

   drift 
  in 
  the 
  region 
  of 
  the 
  interlobate 
  moraine 
  and 
  by 
  the 
  receding 
  

   ice 
  of 
  the 
  Sacandaga 
  in 
  the 
  direction 
  of 
  Batchellerville 
  and 
  Conklin- 
  

   ville. 
  The 
  basal 
  deposits 
  of 
  the 
  Vly 
  are 
  undoubtedly 
  sediments 
  of 
  

   this 
  lake 
  overlain 
  by 
  large 
  accumulations 
  of 
  swamp 
  and 
  vegetable 
  

   material. 
  The 
  most 
  interesting 
  and 
  distinctly 
  formed 
  delta 
  or 
  the 
  

   district 
  was 
  built 
  by 
  the 
  issuing 
  waters 
  of 
  the 
  Sacandaga 
  glacier
