  The 
  inquiry 
  has 
  afforded 
  general 
  suggestions 
  as 
  to 
  the 
  amount 
  

   of 
  glacial 
  reduction 
  of 
  the 
  surface 
  of 
  the 
  district. 
  The 
  northern 
  

   section 
  seems 
  to 
  have 
  suffered 
  most. 
  At 
  and 
  south 
  of 
  the 
  

   moraine 
  which 
  runs 
  so 
  nearly 
  coincident 
  with 
  the 
  divide, 
  the 
  

   hills 
  are 
  often 
  drumlin-like, 
  or 
  at 
  least 
  show 
  much 
  fluting, 
  dis- 
  

   playing 
  the 
  " 
  linear 
  " 
  topography 
  to 
  perfection. 
  On 
  the 
  slope 
  

   which 
  descends 
  to 
  the 
  Mohawk, 
  the 
  ice 
  acted 
  with 
  power. 
  In 
  

   the 
  southern 
  section, 
  the 
  country 
  was 
  less 
  effectively 
  scored 
  

   and 
  was 
  planed 
  during 
  a 
  shorter 
  period. 
  The 
  bowlder 
  drift 
  in 
  

   the 
  best 
  strewn 
  fields 
  is 
  more 
  impressive 
  in 
  its 
  appearance, 
  

   than 
  its 
  actual 
  cubic 
  contents 
  would 
  justify. 
  The 
  Lower 
  Hel- 
  

   derberg 
  shelf 
  at 
  Oriskany 
  Falls, 
  so 
  conspicuously 
  stripped 
  of 
  

   the 
  superjacent 
  sandstones, 
  would 
  probably 
  much 
  more 
  than 
  

   receive 
  all 
  the 
  Oriskany 
  bowlders 
  dispersed 
  to 
  the 
  southward, 
  

   if 
  brought 
  back 
  and 
  corded 
  to 
  the 
  thickness 
  of 
  the 
  ledge 
  from 
  

   which 
  they 
  were 
  borne. 
  If 
  we 
  say 
  that 
  four 
  times 
  as 
  much 
  

   sandstone 
  has 
  been 
  crushed 
  and 
  carried 
  down 
  the 
  valleys 
  and 
  

   to 
  the 
  sea, 
  the 
  amount 
  would 
  still 
  be 
  relatively 
  insignificant. 
  

   Erosion 
  in 
  certain 
  situations, 
  redistribution 
  within 
  moderate 
  

   distances, 
  and 
  topographic 
  changes, 
  have 
  been 
  very 
  great. 
  

   Actual 
  reduction 
  of 
  the 
  general 
  surface 
  toward 
  base 
  level 
  

   doubtless 
  proceeded 
  rapidly 
  during 
  glacial 
  time, 
  but 
  even 
  then, 
  

   the 
  process 
  was 
  rapid 
  only 
  in 
  the 
  geological 
  sense, 
  and 
  the 
  

   result 
  a 
  minute 
  fraction 
  of 
  what 
  has 
  been 
  accomplished 
  since 
  

   the 
  region 
  became 
  a 
  land 
  surface.

  1. 
  On 
  the 
  Determination 
  of 
  high 
  Fusing 
  Points. 
  — 
  A 
  new 
  

   method 
  of 
  determining 
  high 
  fusing 
  points 
  has 
  been 
  devised 
  by 
  

   Victor 
  Meter 
  in 
  conjunction 
  with 
  Riddle 
  and 
  Lamb, 
  based 
  on 
  

   the 
  principle 
  of 
  measuring 
  the 
  temperature 
  by 
  means 
  of 
  a 
  small 
  

   air 
  thermometer 
  made 
  of 
  platinum. 
  At 
  the 
  instant 
  when 
  the 
  

   substance 
  under 
  examination 
  fuses, 
  the 
  air 
  in 
  this 
  thermometer 
  is 
  

   expelled 
  by 
  means 
  of 
  a 
  soluble 
  gas, 
  into 
  a 
  graduated 
  tube 
  con- 
  

   taining 
  a 
  liquid 
  in 
  which 
  the 
  expelling 
  gas 
  is 
  dissolved. 
  The 
  

   substance 
  to 
  be 
  examined 
  is 
  placed 
  in 
  a 
  small 
  platinum 
  tube, 
  

   which 
  is 
  attached 
  to 
  the 
  bulb 
  of 
  the 
  air 
  thermometer, 
  and 
  the 
  

   whole 
  is 
  immersed 
  in 
  a 
  fused 
  salt 
  having 
  a 
  melting 
  point 
  consid- 
  

   erably 
  below 
  that 
  of 
  the 
  substance. 
  The 
  air 
  thermometer 
  con- 
  

   sists 
  of 
  a 
  spherical 
  bulb 
  of 
  platinum, 
  about 
  25 
  cc 
  in 
  its 
  capacity, 
  

   having 
  two 
  somewhat 
  long 
  capillary 
  tubes 
  of 
  the 
  same 
  metal 
  

   attached 
  to 
  it, 
  one 
  of 
  which 
  just 
  enters 
  the 
  bulb 
  while 
  the 
  other
