  Followiug 
  is 
  a 
  record 
  of 
  the 
  meteorological 
  observations 
  made 
  at 
  tlie 
  

   station 
  during 
  the 
  year 
  : 
  

  

  St. 
  Johnsbury 
  Station, 
  Vermont 
  (J. 
  W^. 
  Titcomb, 
  Superixtendknt). 
  

  

  At 
  tlie 
  beginiiiug- 
  of 
  the 
  fiscal 
  year 
  the 
  stock 
  of 
  fisli 
  on 
  hand 
  at 
  the 
  

   station 
  consisted 
  of 
  0,673 
  steelhead 
  trout 
  and 
  22,875 
  lake 
  trout. 
  The 
  

   water 
  supply 
  to 
  the 
  hatchery 
  at 
  this 
  time 
  was 
  taken 
  from 
  a 
  small 
  brook 
  

   on 
  the 
  station 
  property, 
  supplied 
  by 
  springs, 
  and 
  varying 
  in 
  volume 
  

   from 
  8 
  gallons 
  of 
  pure 
  water 
  to 
  100 
  of 
  surface 
  water. 
  As 
  it 
  was 
  con- 
  

   ducted 
  to 
  the 
  hatchery 
  in 
  an 
  open 
  ditch, 
  it 
  was 
  subject 
  to 
  changes 
  in 
  

   temperature, 
  and 
  was 
  therefore 
  about 
  the 
  same 
  as 
  the 
  temperature 
  of 
  

   the 
  water 
  in 
  Sleeper 
  River, 
  from 
  which 
  the 
  supply 
  was 
  taken 
  later 
  in 
  

   the 
  summer. 
  In 
  July 
  all 
  of 
  the 
  lake 
  trout 
  died, 
  owing 
  to 
  the 
  high 
  tem- 
  

   perature, 
  which 
  also 
  caused 
  a 
  heavy 
  mortality 
  among 
  the 
  steelheads. 
  

   During 
  July 
  and 
  November 
  plants 
  of 
  steelliead 
  trout 
  amounting 
  to 
  

   4,777 
  were 
  made 
  in 
  the 
  tributaries 
  of 
  Lake 
  Champlain, 
  and 
  on 
  May 
  5 
  

   258 
  were 
  deposited 
  in 
  the 
  Merrimac 
  River 
  at 
  Concord. 
  At 
  the 
  close 
  of 
  

   of 
  the 
  year 
  90 
  yearlings 
  were 
  left 
  on 
  hand. 
  

  

  During 
  the 
  summer 
  preparations 
  were 
  made 
  to 
  obtain 
  spawn 
  of 
  the 
  

   native 
  brook 
  trout 
  from 
  streams 
  and 
  ponds 
  in 
  various 
  parts 
  of 
  the 
  State, 
  

   and 
  the 
  following 
  collections 
  were 
  made 
  at 
  the 
  six 
  points 
  selected: 
  

   Darling 
  Pond, 
  Groton, 
  106,905; 
  Pico 
  Pond, 
  Shrewsbury, 
  20,000;

  The 
  first 
  eggs 
  were 
  taken 
  on 
  October 
  1 
  at 
  Pico 
  and 
  the 
  last 
  on 
  

   November 
  26 
  at 
  Fairbanks. 
  Owing 
  to 
  the 
  different 
  conditions 
  exist- 
  

   ing 
  in 
  the 
  various 
  lakes, 
  different 
  methods 
  had 
  to 
  be 
  adopted 
  in 
  cap- 
  

   turing 
  the 
  fish. 
  At 
  Pico, 
  Sherburne, 
  and 
  Darling 
  ponds, 
  where 
  the 
  

   fish 
  enter 
  small 
  tributary 
  streams 
  to 
  spawn, 
  V-shaped 
  slat 
  traps 
  were
