  throughout 
  the 
  work, 
  and 
  the 
  system 
  of 
  quarter-second 
  pendu- 
  

   lums 
  for 
  gravity 
  purposes 
  exhibited 
  and 
  described 
  at 
  a 
  previous 
  

   meeting 
  of 
  the 
  Academy. 
  These 
  little 
  pendulums, 
  not 
  more 
  

   than 
  five 
  or 
  six 
  centimeters 
  in 
  length, 
  have 
  proved, 
  under 
  the 
  

   test 
  to 
  which 
  they 
  were 
  thus 
  submitted, 
  to 
  be 
  quite 
  accurate 
  

   and 
  reliable 
  in 
  their 
  performance, 
  and 
  their 
  lightness 
  and 
  

   convenience 
  in 
  transportation 
  will 
  doubtless 
  render 
  them 
  of 
  

   considerable 
  service 
  in 
  future 
  gravity 
  campaigns 
  where 
  the 
  

   conditions 
  of 
  travel 
  and 
  observation 
  are 
  difficult 
  and 
  trying. 
  

   It 
  was 
  also 
  observed, 
  by 
  very 
  careful 
  comparisons 
  of 
  the 
  periods 
  

   of 
  the 
  pendulums 
  of 
  both 
  types, 
  both 
  before 
  and 
  after 
  the 
  

   campaign 
  made 
  at 
  the 
  base 
  station 
  at 
  Washington, 
  that 
  there 
  

   was 
  almost, 
  if 
  not 
  quite, 
  no 
  sensible 
  wearing 
  of 
  the 
  agate 
  knife 
  

   edges, 
  thus 
  demonstrating 
  the 
  efficiency 
  of 
  the 
  combination 
  of 
  

   plane 
  and 
  edge 
  which 
  was 
  a 
  year 
  or 
  two 
  ago 
  first 
  presented 
  to 
  

   the 
  National 
  Academy.*

  Observation 
  upon 
  the 
  Glacial 
  Phenomena 
  of 
  

   Newfoundland, 
  Labrador 
  and 
  Southern 
  Greenland 
  ;

   G.

  Wright. 
  

  

  Dr. 
  F. 
  A. 
  Cook's 
  expedition 
  to 
  the 
  Arctic 
  regions 
  in 
  the 
  

   summer 
  of 
  1894 
  met 
  with 
  many 
  reverses, 
  ending 
  in 
  the 
  loss 
  of 
  

   the 
  Steamer 
  Miranda 
  and 
  of 
  the 
  valuable 
  collections 
  which 
  

   had 
  been 
  made 
  by 
  the 
  naturalists 
  on 
  board. 
  But 
  the 
  oppor- 
  

   tunities 
  for 
  glacial 
  investigation 
  were 
  on 
  the 
  whole 
  as 
  good 
  as 
  

   could 
  have 
  been 
  reasonably 
  expected. 
  The 
  delays 
  afforded 
  

   nearly 
  a 
  week 
  for 
  observations 
  in 
  Newfoundland, 
  and 
  about 
  

   the 
  same 
  length 
  of 
  time 
  at 
  three 
  different 
  points 
  in 
  Labrador, 
  

   namely 
  at 
  Henley 
  Harbor, 
  St. 
  Charles 
  Harbor, 
  and 
  the 
  Punch 
  

   P>owl, 
  while 
  two 
  weeks 
  were 
  at 
  our 
  disposal 
  in 
  Greenland 
  in 
  

   the 
  vicinity 
  of 
  Sukkertoppen 
  in 
  latitude 
  65*25, 
  where 
  the 
  

   inland 
  ice 
  sends 
  a 
  projection 
  down 
  to 
  within 
  fifteen 
  miles 
  of 
  

   the 
  open 
  sea. 
  Besides 
  spending 
  a 
  week 
  in 
  camp 
  at 
  the 
  edge 
  

   of 
  this 
  portion 
  of 
  the 
  inland 
  ice, 
  we 
  made 
  an 
  excursion 
  up 
  

   Isortoki 
  Fiord 
  to 
  a 
  distance 
  of 
  twenty-five 
  miles, 
  having 
  oppor- 
  

  

  * 
  Since 
  the 
  above 
  was 
  written 
  I 
  have 
  received 
  a 
  letter 
  from 
  Mr. 
  Putnam 
  in 
  

   which 
  lie 
  informs 
  me 
  that 
  he 
  has 
  since 
  added 
  two 
  or 
  three 
  stations 
  to 
  the 
  list 
  as 
  

   given 
  above. 
  He 
  also 
  makes 
  the 
  important 
  suggestion 
  that 
  a 
  similar 
  line 
  of 
  

   gravity 
  stations 
  should 
  be 
  run 
  across 
  the 
  southern 
  part 
  of 
  the 
  country. 
  " 
  We 
  

   would 
  then," 
  he 
  says. 
  " 
  get 
  in 
  another 
  latitude 
  a 
  variety 
  of 
  conditions 
  not 
  found 
  

   in 
  the 
  past 
  season 
  ; 
  a 
  sea 
  coast 
  free 
  from 
  the 
  mountains, 
  along 
  the 
  Gulf 
  Coasts 
  an 
  

   immense 
  area 
  of 
  deposits, 
  farther 
  to 
  the 
  west 
  a 
  long, 
  rising 
  swell 
  comparatively 
  

   little 
  disturbed 
  with 
  mountains, 
  and 
  beyond 
  a 
  great 
  depression 
  below 
  sea 
  level." 
  

   It 
  is 
  earnestly 
  hoped 
  that 
  he 
  may 
  be 
  allowed 
  to 
  execute 
  this 
  interesting 
  piece 
  of 
  

   work.
