  A

  Interviews 
  with 
  different 
  persons 
  who 
  si)end 
  the 
  spring 
  and 
  summer 
  

   in 
  the 
  Judith 
  and 
  Musselshell 
  basins 
  all 
  show 
  that 
  this 
  year 
  there 
  are 
  

   no 
  locusts 
  except 
  natives 
  in 
  the 
  country 
  bordering 
  on 
  and 
  drained 
  by 
  

   these 
  two 
  rivers 
  and 
  their 
  tributaries. 
  Several 
  say 
  they 
  could 
  scarcely 
  

   find 
  enough 
  'hoppers 
  to 
  bait 
  for 
  fish. 
  Duriug 
  the 
  latter 
  part 
  of 
  July 
  

   and 
  early 
  August, 
  1876, 
  while 
  in 
  these 
  two 
  valleys, 
  saw 
  numerous 
  

   and 
  large 
  swarms 
  moving 
  west 
  for 
  three 
  weeks. 
  They 
  were 
  hatched 
  in 
  

   this 
  country 
  and 
  north. 
  Also 
  swarms 
  in 
  August, 
  1878, 
  moving 
  south, 
  

   sui)posed 
  to 
  have 
  been 
  hatched 
  in 
  the 
  British 
  provinces, 
  north 
  of 
  As- 
  

   siniboine. 
  Also 
  report 
  of 
  swarms 
  occurring 
  in 
  these 
  basins 
  from 
  1873 
  to 
  

   1876 
  — 
  one 
  year 
  in 
  particular, 
  when 
  they 
  flew 
  in 
  such 
  numbers 
  as 
  to 
  ob- 
  

   scure 
  the 
  sun 
  for 
  three 
  days 
  (Goodale). 
  We 
  cannot 
  give 
  the 
  dates 
  or 
  

   direction 
  of 
  flights 
  for 
  these 
  years. 
  

  

  Northwestern 
  Wyoming 
  was 
  visited 
  by 
  swarms 
  in 
  August, 
  1878, 
  from 
  

   the 
  northeast 
  and 
  flying 
  to 
  the 
  southwest. 
  They 
  were 
  so 
  ravenous 
  as 
  

   to 
  eat 
  articles 
  of 
  clothing 
  left 
  lying 
  on 
  the 
  ground 
  (Soldier). 
  

  

  Eeport 
  of 
  a 
  small 
  swarm 
  of 
  locusts 
  flying 
  eastward 
  through 
  Wyoming 
  

   along 
  route 
  of 
  Union 
  Pacific 
  Eailway 
  last 
  summer, 
  1879.

  dates 
  or 
  particulars. 
  

  

  Eeports 
  from 
  British 
  America 
  claim 
  no 
  locusts 
  this 
  year 
  in 
  the 
  imme- 
  

   diate 
  vicinity 
  of 
  the 
  line 
  adjoiniug 
  Montana 
  j 
  nor 
  can 
  I 
  learn 
  of 
  any 
  in 
  

   the 
  Milk 
  Eiver 
  country. 
  But 
  in 
  the 
  spring 
  of 
  1878 
  great 
  numbers 
  were 
  

   known 
  to 
  breed 
  both 
  in 
  the 
  Milk 
  Eiver 
  country 
  and 
  the 
  British 
  posses- 
  

   sions 
  adjoiniug. 
  Never 
  saw 
  many 
  locusts 
  in 
  the 
  mountains 
  of 
  British 
  

   America 
  where 
  he 
  vv 
  as 
  prospecting 
  for 
  a 
  number 
  of 
  years 
  (Miner). 
  

  

  From 
  these 
  data 
  it 
  would 
  appear 
  that 
  the 
  present 
  year 
  finds 
  the 
  en- 
  

   tire 
  Northwest 
  comparatively 
  free 
  from 
  this 
  great 
  pest, 
  and 
  probably 
  

   the 
  entire 
  country. 
  Of 
  course, 
  as 
  I 
  have 
  already 
  mentioned, 
  there 
  are 
  

   a 
  few 
  isolated 
  areas 
  over 
  which 
  small 
  numbers 
  of 
  this 
  species 
  still 
  exist; 
  

   but 
  those 
  which 
  I 
  visited 
  are 
  so 
  small 
  and 
  the 
  locusts 
  on 
  them 
  so 
  few 
  

   that 
  I 
  do 
  not 
  think 
  they 
  will 
  migrate 
  or 
  increase 
  to 
  suflicient 
  numbers 
  

   to 
  do 
  damage 
  for 
  the 
  next 
  three 
  or 
  four 
  years, 
  and 
  perhaps 
  for 
  a 
  much 
  

   greater 
  length 
  of 
  time. 
  It 
  is 
  true 
  reports 
  have 
  come 
  from 
  several 
  locali- 
  

   ties 
  that 
  crops 
  were 
  partially 
  destroyed 
  by 
  "grasshoppers," 
  but 
  might 
  

   they 
  not 
  be 
  other 
  species 
  ? 
  If 
  they 
  were 
  of 
  the 
  migratory 
  kind, 
  I 
  should 
  

   think 
  that 
  we 
  should 
  hear 
  more 
  of 
  them 
  than 
  we 
  do.

  Some 
  might 
  think 
  that 
  in 
  this 
  out-of-the-way 
  country 
  the 
  locust 
  would 
  

   be 
  entirely 
  free 
  from 
  euemies 
  of 
  all 
  kindSj 
  but 
  such 
  is 
  not 
  the 
  case.
