  powder 
  would 
  meet 
  all 
  requirements. 
  Work 
  of 
  this 
  character 
  should 
  

   be 
  done 
  during 
  the 
  winter, 
  when 
  the 
  water 
  is 
  low. 
  

  

  As 
  an 
  example 
  of 
  the 
  streams 
  under 
  discussion, 
  there 
  may 
  be 
  cited 
  

   Mill 
  Creek, 
  which 
  is 
  7 
  miles 
  from 
  Wrangell. 
  At 
  the 
  mouth 
  of 
  this 
  

   stream 
  there 
  is 
  one 
  almost 
  sheer 
  drop 
  of 
  6 
  or 
  8 
  feet, 
  even 
  at 
  higher 
  

   stages 
  of 
  the 
  tide, 
  and 
  above 
  this 
  is 
  a 
  series 
  of 
  cascades 
  with 
  a 
  fall 
  of 
  

   probably 
  25 
  feet 
  in 
  a 
  distance 
  of 
  about 
  75 
  yards. 
  Were 
  a 
  fishway 
  

   installed 
  at 
  the 
  first 
  drop, 
  and 
  a 
  few 
  resting 
  places 
  blasted 
  out 
  in 
  the 
  

   series 
  of 
  cascades, 
  salmon 
  could 
  get 
  into 
  the 
  stream 
  above, 
  which 
  is 
  

   about 
  a 
  mile 
  long, 
  and 
  then 
  pass 
  into 
  a 
  fine 
  lake 
  2^ 
  miles 
  in 
  length. 
  

   Each 
  season 
  considerable 
  numbers 
  of 
  salmon 
  collect 
  off 
  the 
  mouth 
  of 
  

   the 
  stream, 
  but 
  their 
  attempts 
  to 
  pass 
  the 
  falls 
  are 
  without 
  exception 
  

   unsuccessful. 
  It 
  is 
  particularly 
  desirable 
  to 
  open 
  up 
  a 
  stream 
  like 
  

   Mill 
  Creek, 
  which 
  heads 
  in 
  a 
  lake 
  and 
  therefore 
  will 
  be 
  ascended 
  by 
  

   red 
  salmon. 
  When 
  funds 
  are 
  made 
  available, 
  effective 
  work 
  can 
  be 
  

   done 
  in 
  accomplishing 
  this 
  end.

  Under 
  date 
  of 
  August 
  8, 
  1913, 
  the 
  Bureau 
  of 
  Lighthouses 
  issued 
  

   circular 
  letter 
  No. 
  329 
  to 
  lighthouse 
  inspectors, 
  stating 
  that 
  the 
  Sec- 
  

   retary 
  of 
  Commerce 
  had 
  approved 
  the 
  following 
  regulation, 
  which 
  

   will 
  be 
  included 
  in 
  permits 
  that 
  may 
  be 
  granted 
  by 
  the 
  War 
  Depart- 
  

   ment 
  for 
  the 
  erection 
  of 
  fishing 
  structures 
  and 
  appliances 
  in 
  navigable 
  

   waters 
  of 
  the 
  United 
  States: 
  

  

  Fishing 
  structures 
  and 
  appliances 
  in 
  naA-igable 
  waters 
  of 
  the 
  United 
  States 
  shall 
  be 
  

   lighted 
  for 
  the 
  safety 
  of 
  navigation, 
  as 
  follows: 
  

  

  The 
  lights 
  shall 
  be 
  displayed 
  between 
  sunset 
  and 
  sunrise. 
  They 
  shall 
  be 
  placed 
  

   at 
  each 
  end 
  of 
  the 
  structure, 
  excepting 
  where 
  the 
  inner 
  end 
  terminates 
  in 
  such 
  situa- 
  

   tion 
  that 
  there 
  is 
  no 
  practicable 
  navigation 
  between 
  it 
  and 
  the 
  high-water 
  line 
  of 
  the 
  

   adjacent 
  coast, 
  in 
  which 
  case 
  no 
  inner 
  light 
  shall 
  be 
  displayed. 
  The 
  outer 
  light 
  shall 
  

   be 
  white 
  and 
  the 
  inner 
  light 
  shall 
  be 
  red. 
  The 
  size, 
  capacity, 
  and 
  manner 
  of 
  main- 
  

   tenance 
  of 
  the 
  lights 
  shall 
  be 
  such 
  as 
  may 
  be 
  specified 
  in 
  the 
  War 
  Department 
  permit 
  

   authorizing 
  the 
  erection 
  of 
  the 
  structure 
  or 
  appliance. 
  

  

  "When 
  several 
  structures 
  or 
  appliances 
  are 
  placed 
  on 
  one 
  line, 
  with 
  no 
  navigable 
  

   passage 
  between 
  them, 
  they 
  will 
  be 
  considered, 
  for 
  lighting 
  purposes, 
  as 
  one 
  structure. 
  

  

  , 
  Trap-Site 
  Surveys. 
  

  

  In 
  anticipation 
  of 
  early 
  revision 
  by 
  Congress 
  of 
  the 
  present 
  Alaska 
  

   fisheries 
  laws, 
  there 
  has 
  been 
  considerable 
  activity 
  this 
  season 
  in 
  the 
  

   matter 
  of 
  surveying 
  trap 
  sites. 
  Several 
  of 
  the 
  larger 
  companies 
  as 
  

   well 
  as 
  a 
  number 
  of 
  individual 
  trap 
  owners 
  have 
  been 
  to 
  considerable 
  

   expense 
  in 
  having 
  surveys 
  made. 
  Since 
  there 
  has 
  been 
  no 
  definitely 
  

   established 
  standard 
  for 
  surveying 
  or 
  determining 
  the 
  exact 
  size 
  and 
  

   position 
  of 
  fish 
  trap 
  sites, 
  these 
  efforts 
  would 
  seem 
  to 
  be 
  somewhat 
  

   premature. 
  However, 
  in 
  the 
  event 
  of 
  much-needed 
  trap 
  legishition 
  

   by 
  Congress, 
  possibly 
  at 
  least 
  a 
  part 
  of 
  the 
  work 
  akeady 
  done 
  may 
  

   be 
  made 
  to 
  apply 
  to 
  future 
  requirements.
