  REPORT

  COMMISSION. 
  

  

  At 
  Missoula 
  many 
  data 
  were 
  obtained 
  in 
  reference 
  to 
  the 
  movements 
  

   of 
  locusts 
  in 
  that 
  portion 
  of 
  Montana. 
  From 
  here 
  I 
  proceeded 
  on 
  horse- 
  

   back 
  down 
  the 
  Missoula 
  Valley, 
  to 
  where 
  Mullan's 
  Wagon 
  Koad 
  crosses 
  

   the 
  Coeur 
  d'Alene 
  Mountains, 
  and 
  thence 
  across 
  the 
  mountains 
  through 
  

   Northern 
  Idaho 
  into 
  Washington 
  Territory. 
  Here 
  I 
  obtained 
  what 
  data 
  

   I 
  could, 
  and 
  then 
  worked 
  my 
  way 
  southward 
  across 
  the 
  Spokane 
  Plateau 
  

   to 
  Walla 
  Walla, 
  the 
  section 
  visited 
  by 
  small 
  swarms 
  of 
  locusts 
  within 
  

   the 
  past 
  few 
  years. 
  Leaving 
  Walla 
  Walla, 
  my 
  homeward 
  journey 
  lay 
  

   down 
  the 
  Columbia 
  to 
  Portland 
  and 
  Astoria, 
  where 
  I 
  was 
  obliged 
  to 
  

   lie 
  over 
  for 
  four 
  days, 
  waiting 
  for 
  the 
  next 
  steamer 
  to 
  San 
  Francisco. 
  

   During 
  this 
  period 
  I 
  went 
  over 
  to 
  Fort 
  Canby, 
  and 
  spent 
  my 
  time 
  in 
  

   making 
  a 
  collection 
  of 
  mosses 
  and 
  ferns, 
  which 
  I 
  herewith 
  send 
  to 
  the 
  

   Department. 
  I 
  also 
  obtained 
  a 
  few 
  land 
  shells. 
  

  

  In 
  making 
  this 
  trip 
  quite 
  a 
  number 
  of 
  favors 
  were 
  extended 
  by 
  the 
  

   following 
  corporations 
  and 
  individuals 
  : 
  Union 
  Pacific 
  Eailway 
  (Ore- 
  

   gon 
  short 
  line), 
  Gilmer 
  & 
  Salisbury, 
  half 
  rate; 
  officers 
  and 
  troops 
  at

  Be- 
  

   sides 
  these 
  I 
  am 
  under 
  great 
  obligations 
  to 
  many 
  others 
  for 
  aid 
  in 
  ac- 
  

   cumulating 
  locust 
  data, 
  as 
  well 
  as 
  those 
  relating 
  to 
  various 
  other 
  in- 
  

   sects. 
  

  

  I 
  have 
  also 
  embodied, 
  at 
  your 
  request, 
  a 
  summary 
  of 
  the 
  probabili- 
  

   ties 
  for 
  the 
  present 
  year, 
  1882.

  GENERAL 
  REPORT 
  ON 
  THE 
  ROOKY 
  MOUNTAIN 
  LOCUST. 
  

  

  It 
  is 
  not 
  my 
  intention 
  in 
  this 
  report 
  to 
  describe 
  all 
  of 
  the 
  facts 
  gleaned 
  

   or 
  to 
  note 
  the 
  work 
  done 
  by 
  the 
  Commission 
  and 
  others 
  in 
  reference 
  to 
  

   this 
  insect. 
  I 
  will, 
  however, 
  give 
  a 
  condensed 
  account 
  of 
  the 
  more 
  im- 
  

   portant 
  points 
  that 
  directly 
  treat 
  upon 
  the 
  means 
  of 
  their 
  diminution 
  

   and 
  prevention 
  in 
  future, 
  with 
  a 
  few 
  additionaHraits 
  noticed 
  during 
  the 
  

   past 
  season. 
  Of 
  course 
  it 
  will 
  be 
  necessary 
  occasionally 
  to 
  allude 
  to 
  

   matters 
  mentioned 
  in 
  the 
  annual 
  reports 
  of 
  the 
  Commission, 
  and 
  also 
  to 
  

   other 
  records 
  relating 
  to 
  the 
  life-history 
  and 
  depredations 
  of 
  this 
  and 
  

   other 
  locusts. 
  Before 
  entering 
  upon 
  a 
  discussion 
  of 
  this 
  subject, 
  I 
  will 
  

   give 
  a 
  brief 
  history 
  of 
  this 
  insect 
  and 
  its 
  depredations 
  in 
  various 
  por- 
  

   tions 
  of 
  the 
  country 
  which 
  it 
  visits 
  in 
  the 
  course 
  of 
  its 
  migrations. 
  

  

  Up 
  to 
  the 
  time 
  of 
  the 
  settlement 
  of 
  portions 
  of 
  Eastern 
  Kansas, 
  Ne- 
  

   braska, 
  and 
  part 
  of 
  Minnesota, 
  comparatively 
  little 
  was 
  known 
  of 
  locust 
  

   swarms 
  and 
  their 
  magnitude 
  in 
  North 
  America. 
  At 
  long 
  intervals 
  only
