  WORK 
  OF 
  STEAMER 
  ALBATROSS.

  given 
  by 
  the 
  crew, 
  some 
  of 
  whom 
  were 
  nearly 
  always 
  at 
  hand 
  with 
  

   scoop-nets 
  ready 
  to 
  capture 
  anything 
  coming 
  within 
  reach. 
  

  

  The 
  large 
  surface 
  net 
  was 
  used 
  after 
  dark 
  with 
  the 
  best 
  results. 
  In 
  

   the 
  day-time 
  it 
  was 
  not 
  so 
  successful. 
  Some 
  of 
  the 
  more 
  interesting 
  

   surface 
  hsh 
  were 
  placed 
  in 
  the 
  aquarium 
  and 
  brought 
  into 
  Wood's 
  Holl 
  

   alive. 
  Three 
  specimens 
  of 
  Argonauta 
  argo 
  were 
  placed 
  in 
  jars, 
  and 
  the 
  

   water 
  was 
  kept 
  running 
  through 
  in 
  the 
  hope 
  of 
  keeping 
  them 
  alive. 
  

   One 
  lived 
  for 
  three 
  days, 
  and 
  was 
  killed 
  not 
  unlikely 
  by 
  the 
  change 
  in 
  

   the 
  temperature 
  of 
  the 
  water 
  from 
  75° 
  to 
  00° 
  F. 
  Early 
  in 
  the 
  evening 
  of 
  

   September 
  2 
  a 
  petrel 
  flew 
  on 
  board, 
  blinded, 
  no 
  doubt, 
  by 
  the 
  electric 
  

   light. 
  As 
  soon 
  as 
  convenient 
  the 
  bird 
  was 
  skinned; 
  and 
  upon 
  the 
  ar- 
  

   rival 
  of 
  the 
  ship 
  in 
  Wood's 
  Jloll 
  it 
  was 
  sent 
  to 
  Mr. 
  Uidgway, 
  curator 
  

   of 
  the 
  department 
  of 
  birds, 
  National 
  Museum. 
  Mr. 
  Iiidgway 
  found 
  

   the 
  bird 
  to 
  be 
  the 
  Pelagodroma 
  marina 
  (Lath.) 
  of 
  Australia, 
  and 
  never 
  

   before 
  found 
  in 
  the 
  North 
  Atlantic 
  and 
  but 
  twice 
  in 
  the 
  South 
  Atlantic. 
  

   The 
  position 
  of 
  the 
  ship 
  when 
  the 
  bird 
  was 
  taken 
  was 
  latitude 
  N. 
  43° 
  

   34' 
  18", 
  longitude 
  W. 
  CG°

  The 
  sixth 
  cruise 
  was 
  from 
  Wood's 
  lfoll, 
  and 
  lasted 
  from 
  the 
  17th 
  to 
  

   the 
  _55th 
  of 
  September. 
  Ten 
  hauls 
  were 
  made 
  with 
  the 
  beam-trawl, 
  and 
  

   more 
  than 
  the 
  usual 
  time 
  was 
  spent 
  in 
  surface 
  collecting. 
  Our 
  large 
  

   surface 
  nets 
  were 
  used 
  as 
  often 
  as 
  possible, 
  one 
  from 
  each 
  side 
  of 
  the 
  

   ship. 
  These 
  nets 
  strain 
  water 
  through 
  their 
  meshes 
  at 
  the 
  rate 
  of 
  nearly 
  

   12,000 
  gallons 
  per 
  minute 
  when 
  the 
  ship 
  is 
  moving 
  at 
  the 
  rate 
  of 
  2 
  miles 
  

   an 
  hour. 
  At 
  the 
  rate 
  of 
  10,000 
  gallons 
  per 
  net 
  the 
  amount 
  of 
  water 
  

   strained 
  in 
  an 
  hour 
  would 
  be 
  for 
  both 
  nets 
  1,200,000 
  gallons. 
  The 
  use 
  of 
  

   this 
  net 
  began 
  with 
  the 
  first 
  cruise 
  of 
  the 
  year, 
  and 
  has 
  been 
  very 
  satis- 
  

   factory, 
  only 
  the 
  very 
  smallest 
  objects 
  escaping 
  through 
  its 
  meshes. 
  As 
  

   might 
  be 
  expected 
  from 
  the 
  large 
  amount 
  of 
  water 
  passing 
  through 
  it, 
  

   many 
  rare 
  forms 
  offish 
  and 
  invertebrates 
  are 
  taken 
  during 
  a 
  cruise. 
  

  

  The 
  last 
  cruise 
  was 
  from 
  New 
  York 
  to 
  Washington, 
  going 
  south 
  as 
  

   f;ir 
  as 
  the 
  coast 
  of 
  North 
  Carolina. 
  Leaving 
  New 
  York 
  on 
  Oetober 
  15, 
  the 
  

   ship 
  sailed 
  southward, 
  stopping 
  to 
  do 
  surface 
  work 
  morning 
  and 
  even- 
  

   ing 
  whenever 
  practical. 
  Before 
  daylight 
  on 
  the 
  Kith 
  the 
  large 
  net 
  was 
  

   put 
  over 
  and 
  towed 
  for 
  an 
  hour, 
  taking 
  hundreds 
  offish 
  of 
  one 
  species 
  

   and 
  a 
  few 
  of 
  a 
  dozen 
  others. 
  The 
  invertebrates 
  taken 
  at 
  the 
  same 
  time 
  

   were 
  numerous 
  and 
  interesting. 
  Among 
  the 
  mollusks 
  were 
  several 
  

   species 
  of 
  Salpse, 
  Pteropods, 
  Heteropods, 
  and 
  one 
  small 
  male 
  argo- 
  

   naut. 
  The 
  preservation 
  of 
  the 
  large 
  amount 
  of 
  varied 
  material 
  taken 
  

   by 
  the 
  net 
  requires 
  the 
  attention 
  of 
  at 
  least 
  one 
  collector 
  the 
  greater 
  

   part 
  of 
  the 
  time. 
  During 
  the 
  cruise 
  thirty-seven 
  hauls 
  were 
  made, 
  

   Nos. 
  2592 
  to 
  2628, 
  inclusive. 
  The 
  last 
  five 
  were 
  on 
  very 
  rich 
  ground 
  in 
  

   water 
  about 
  250 
  fathoms 
  in 
  depth. 
  The 
  ship 
  reached 
  Washington 
  ou 
  

   the 
  24th 
  of 
  October. 
  

  

  The 
  number 
  of 
  hauls 
  made 
  on 
  the 
  various 
  cruises 
  is 
  three 
  hundred 
  

   and 
  eighteen.
