  revolutions. 
  From 
  the 
  main 
  shaft 
  the 
  power 
  was 
  distributed 
  to 
  the 
  

   individual 
  fans 
  by 
  belts, 
  in 
  a 
  manner 
  not 
  materially 
  different 
  from 
  

   that 
  described 
  for 
  the 
  Wickford 
  apparatus. 
  

  

  The 
  rearing 
  plant 
  completed, 
  the 
  engine 
  was 
  started 
  June 
  3, 
  and 
  

   continued 
  to 
  run 
  day 
  and 
  night 
  until 
  the 
  close 
  of 
  the 
  experiments 
  on 
  

   July 
  19. 
  In 
  order 
  to 
  have 
  water 
  free 
  from 
  contamination, 
  the 
  plant 
  

   was 
  removed 
  from 
  the 
  "pool" 
  at 
  the 
  station 
  and 
  anchored 
  in 
  the 
  edge 
  

   of 
  the 
  tide 
  near 
  Devils 
  Foot 
  Island. 
  The 
  depth 
  of 
  the 
  water 
  was 
  15 
  

   feet, 
  and 
  it 
  was 
  thought 
  that 
  the 
  current 
  through 
  the 
  Hole 
  would 
  

   bring 
  a 
  large 
  amount 
  of 
  natural 
  food 
  into 
  the 
  bag. 
  The 
  current 
  was 
  

   too 
  strong, 
  however, 
  and 
  the 
  dirt 
  and 
  debris 
  suspended 
  in 
  the 
  water 
  

   were 
  deposited 
  on 
  the 
  bag 
  and 
  soon 
  prevented 
  circulation. 
  There- 
  

   fore, 
  on 
  June 
  9 
  the 
  plant 
  was 
  towed 
  to 
  the 
  head 
  of 
  Great 
  Harbor 
  and 
  

   anchored 
  in 
  8 
  or 
  10 
  feet 
  of 
  water. 
  The 
  conditions 
  proving 
  more 
  fav- 
  

   orable 
  here, 
  where 
  they 
  more 
  nearly 
  approached 
  those 
  at 
  Wickford, 
  

   the 
  apparatus 
  was 
  kept 
  at 
  this 
  place 
  until 
  the 
  close 
  of 
  the 
  season. 
  

  

  The 
  effoi'ts 
  to 
  rear 
  and 
  plant 
  a 
  large 
  number 
  of 
  lobsters 
  were 
  not 
  as 
  

   successful 
  as 
  had 
  been 
  hoped; 
  nevertheless, 
  fully 
  4,000 
  were 
  brought 
  

   to 
  the 
  fourth 
  stage, 
  and 
  though 
  the 
  number 
  seems 
  small, 
  and 
  could 
  

   doubtless 
  be 
  considerabl}" 
  enlarged 
  during 
  a 
  second 
  season, 
  from 
  pres- 
  

   ent 
  experience 
  and 
  observation 
  upon 
  the 
  habits 
  of 
  the 
  young, 
  and 
  in 
  

   view 
  of 
  the 
  enfeebled 
  condition 
  in 
  which 
  the}' 
  ordinarily 
  leave 
  the 
  

   McDonald 
  jar, 
  the 
  claim 
  is 
  unhesitatingly 
  made 
  that 
  1,000 
  lobsterlings 
  

   have 
  the 
  replenishing 
  value 
  of 
  many 
  million 
  fr3^ 
  The 
  combined 
  

   previous 
  efforts 
  in 
  rearing 
  at 
  Woods 
  Hole 
  had 
  resulted 
  in 
  raising 
  

   not 
  more 
  than 
  500 
  lobsterlings. 
  Compared 
  with 
  this, 
  the 
  results 
  of 
  

   these 
  experiments 
  are 
  magnificent.
