  of 
  the 
  Epilobium 
  Anp;uMfolium. 
  Tliose 
  that 
  I 
  saw 
  at 
  work 
  upon 
  the 
  nets 
  

   were 
  the 
  dilapidated 
  old 
  women. 
  

  

  The 
  following 
  figures 
  and 
  explanation 
  will 
  show 
  how 
  the 
  knot 
  is 
  made, 
  and 
  it 
  

   can 
  be 
  very 
  readily 
  done 
  by 
  any 
  one 
  trying 
  the 
  experiment 
  : 
  

  

  Bring 
  the 
  bight 
  B 
  up 
  through 
  the 
  mesh 
  A, 
  as 
  in 
  fig. 
  1 
  ; 
  draw 
  the 
  part 
  D 
  tight 
  

   at 
  C 
  and 
  press 
  the 
  left 
  thumb 
  upon 
  D 
  to 
  keep 
  the 
  part 
  J 
  D 
  around 
  the 
  mesh- 
  

   block 
  strained 
  ; 
  pass 
  the 
  end 
  E 
  up 
  through 
  the 
  bight 
  B 
  and 
  haul 
  tight 
  to 
  C, 
  as 
  

   shown 
  in 
  fig. 
  2, 
  keeping 
  the 
  thumb 
  as 
  before 
  on 
  the 
  partly 
  formed 
  knot. 
  

  

  With 
  the 
  free 
  part 
  D 
  E 
  of 
  fig. 
  2, 
  pass 
  the 
  bight 
  F 
  down 
  through 
  the 
  mesh 
  

   A, 
  draw 
  the 
  part 
  G 
  tight 
  upon 
  the 
  loop 
  at 
  0, 
  when 
  it 
  will 
  assume 
  the 
  condition 
  

   exhibited 
  in 
  fig. 
  4, 
  slipping 
  the 
  thumb 
  on 
  the 
  part 
  D, 
  to 
  keep 
  tight 
  the 
  loop 
  J 
  

   around 
  the 
  mesh 
  block. 
  With 
  the 
  process 
  in 
  the 
  condition 
  shown 
  by 
  fig. 
  4, 
  pass 
  

   the 
  end 
  E 
  down 
  through 
  the 
  loop 
  H 
  and 
  haul 
  it 
  taut, 
  when 
  the 
  square 
  knot, 
  as 
  

   at 
  I, 
  will 
  necessarily 
  appear 
  by 
  a 
  slight 
  movement 
  of 
  the 
  thumb 
  forward 
  to 
  aid 
  

   it 
  in 
  settling 
  into 
  place. 
  

  

  Dr. 
  Dall 
  gave 
  a 
  brief 
  synopsis 
  of 
  the 
  results 
  of 
  his 
  recent 
  expe- 
  

   dition 
  to 
  Alaska 
  : 
  

  

  The 
  season 
  in 
  the 
  Arctic 
  regions 
  has 
  been 
  an 
  open 
  one 
  and 
  exceedingly 
  aus- 
  

   picious 
  for 
  observations. 
  The 
  expedition 
  has 
  passed 
  a 
  greater 
  portion 
  of 
  the 
  

   time 
  in 
  the 
  vicinity 
  of 
  Mount 
  St. 
  Blias. 
  The 
  scenery 
  of 
  that 
  region 
  was 
  sub- 
  

   lime 
  beyond 
  description, 
  and 
  the 
  greatest 
  glaciers 
  were 
  found 
  there 
  existing 
  out- 
  

   side 
  of 
  the 
  Polar 
  seas. 
  Much 
  attention 
  been 
  given 
  to 
  measuring 
  the 
  altitude 
  of 
  

   Mount 
  St. 
  Elias 
  and 
  the 
  neighboring 
  peaks 
  by 
  careful 
  triangulations, 
  and 
  it 
  was 
  

   determined 
  beyond 
  doubt 
  that 
  St. 
  Elias 
  is 
  the 
  most 
  lofty 
  point 
  of 
  land 
  on 
  the 
  

   North 
  American 
  continent. 
  Its 
  altitude 
  is 
  calculated 
  at 
  19,000 
  feet, 
  and 
  that 
  

   of 
  Mount 
  Fairweather 
  at 
  15,000. 
  It 
  is 
  impossible, 
  however, 
  to 
  fix 
  the 
  precise 
  

   height 
  of 
  the 
  lofty 
  peaks 
  until 
  their 
  ascent 
  can 
  be 
  accomplished. 
  Mount 
  St. 
  

   Elias 
  has 
  been 
  commonly 
  designated 
  in 
  the 
  geographies 
  as 
  a 
  volcanic 
  cone, 
  but 
  

   an 
  examination 
  of 
  its 
  formation, 
  as 
  far 
  as 
  practicable, 
  determined 
  that 
  this 
  sup- 
  

   position 
  is 
  erroneous. 
  Small 
  volcanic 
  vents 
  are 
  discovered, 
  however, 
  toward 
  

   the 
  sea. 
  While 
  sailing 
  close 
  in 
  to 
  the 
  shore, 
  a 
  few 
  miles 
  north 
  of 
  Cape 
  Fair- 
  

   weather, 
  an 
  immense 
  glacier 
  was 
  inspected, 
  having 
  a 
  flow 
  from 
  three 
  to 
  six 
  

   miles 
  in 
  width, 
  and 
  extending 
  inland 
  beyond 
  the 
  reach 
  of 
  vision, 
  which 
  was 
  at 
  

   least 
  thirty 
  miles. 
  The 
  country 
  was 
  of 
  a 
  rolling 
  formation 
  and 
  no 
  material 
  

   deviations 
  appeared 
  within 
  the 
  horizon 
  in 
  the 
  direction 
  of 
  the 
  glacier. 
  The 
  ice 
  

   was 
  clear 
  and 
  blue 
  and 
  glistening 
  in 
  the 
  light, 
  and 
  presented 
  a 
  magnificent 
  

   spectacle.

  Unlike 
  the 
  pliocene, 
  wliich 
  I 
  spoke 
  of 
  at 
  our 
  last 
  meeting, 
  the 
  miocene 
  in 
  

   California 
  furnishes 
  us, 
  so 
  far, 
  with 
  no 
  certain 
  evidence 
  of 
  laud 
  animals' 
  ex-
