  Deer 
  Lodge. 
  They 
  were 
  also 
  abundant 
  at 
  Virginia 
  City 
  and 
  on 
  Sun 
  

   River 
  and 
  on 
  the 
  tipper 
  Missouri 
  between 
  Helena 
  and 
  Fort 
  Benton. 
  

   They 
  were 
  also 
  observed 
  locally 
  in 
  the 
  region 
  south 
  of 
  Yellowstone 
  Park. 
  

  

  In 
  Eastern 
  Oregon 
  swarms 
  were 
  observed 
  between 
  McDonnell's 
  Ferry 
  

   and 
  Blue 
  Mountains. 
  He 
  thus 
  proved 
  that 
  the 
  Rocky 
  Mountain 
  locust 
  

   is 
  indigenous 
  over 
  the 
  immense 
  region 
  already 
  mapped 
  by 
  the 
  Commis- 
  

   sion 
  as 
  the 
  permanent 
  breeding 
  ground, 
  and 
  that 
  the 
  prospect 
  for 
  1879 
  

   was 
  that 
  local 
  injuries 
  would 
  ensue 
  in 
  the 
  Territories, 
  but 
  unless 
  the 
  

   spring 
  and 
  early 
  summer 
  were 
  unusually 
  favorable 
  the 
  Mississippi 
  States 
  

   would 
  not 
  be 
  invaded. 
  

  

  Mr. 
  Thomas 
  visited 
  Colorado 
  and 
  other 
  parts 
  of 
  the 
  West, 
  his 
  special 
  

   object 
  being 
  to 
  ascertain 
  if 
  C. 
  spretus 
  would 
  be 
  found 
  localized 
  in 
  Col- 
  

   orado. 
  He 
  found 
  this 
  to 
  be 
  the 
  case 
  as 
  far 
  south 
  as 
  Colorado 
  Springs, 
  not 
  

   only 
  up 
  in 
  the 
  canons 
  and 
  on 
  the 
  hills 
  and 
  mountains, 
  but 
  on 
  the 
  plains. 
  

   He 
  found 
  them 
  in 
  considerable 
  numbers 
  in 
  one 
  or 
  two 
  canons, 
  and 
  show- 
  

   ing 
  a 
  disposition 
  to 
  migrate. 
  He 
  found 
  specimens 
  on 
  the 
  very 
  tops 
  of 
  

   the 
  range, 
  and 
  on 
  the 
  very 
  top 
  of 
  Pike's 
  Peak. 
  

  

  In 
  Nebraska, 
  Eastern 
  Dakota, 
  Minnesota, 
  Manitoba, 
  and 
  Kansas 
  no 
  

   specimens, 
  with 
  one 
  or 
  two 
  exceptions, 
  were 
  to 
  be 
  found, 
  and 
  their 
  en- 
  

   tire 
  absence 
  showed 
  how 
  completely 
  they 
  had 
  left 
  the 
  Temporary 
  Region, 
  

   and 
  the 
  wisdom 
  of 
  the 
  Commission 
  in 
  so 
  designating 
  the 
  fertile 
  country 
  

   which, 
  in 
  exceptional 
  years, 
  suffers 
  so 
  greatly. 
  

  

  There 
  was 
  one 
  limited 
  locality 
  of 
  a 
  few 
  acres 
  in 
  Southeast 
  Nebraska 
  

   where 
  some 
  hatched 
  out. 
  They 
  were 
  quite 
  injurious 
  around 
  Bismarck, 
  

   destroying 
  the 
  gardens, 
  but 
  they 
  came 
  in 
  from 
  the 
  north. 
  This 
  erup- 
  

   tion, 
  which 
  appeared 
  late 
  in 
  July, 
  was 
  traced 
  from 
  British 
  America 
  to 
  

   Kansas, 
  and 
  was 
  confined 
  to 
  a 
  narrow 
  belt. 
  It 
  did 
  not 
  touch 
  the 
  west- 
  

   ern 
  border 
  of 
  Manitoba, 
  or 
  reach 
  to 
  the 
  middle 
  or 
  interior 
  of 
  Dakota 
  ; 
  

   on 
  the 
  west 
  it 
  did 
  not 
  reach 
  to 
  Fort 
  Benton, 
  but 
  was 
  wholly 
  east 
  of 
  that. 
  

   It 
  touched 
  southern, 
  but 
  did 
  not 
  reach 
  the 
  extreme 
  southeastern 
  part 
  of 
  

   Dakota, 
  passed 
  south 
  in 
  the 
  region 
  of 
  Ponca, 
  Nebr., 
  and 
  thence 
  south 
  

   and 
  southwest 
  into 
  Kansas. 
  

  

  His 
  investigations 
  this 
  year 
  showed 
  a 
  strong 
  tendency 
  to 
  rapid 
  change 
  

   in 
  character 
  of 
  those 
  locusts 
  which 
  remain 
  for 
  a 
  few 
  generations 
  in 
  the 
  

   Sub-permanent 
  Region. 
  A 
  few 
  very 
  limited 
  flights 
  were 
  observed 
  over 
  

   the 
  southwestern 
  part 
  of 
  Minnesota. 
  

  

  At 
  the 
  close 
  of 
  the 
  year 
  it 
  was 
  deemed 
  unwise 
  to 
  publish 
  a 
  final 
  report 
  

   until 
  further 
  investigations 
  had 
  been 
  pursued, 
  and 
  an 
  appropriation 
  of 
  

   $15,000 
  for 
  continuing 
  them 
  was 
  therefore 
  asked 
  of 
  Congress. 
  The 
  appro- 
  

   priation 
  was 
  granted, 
  but 
  with 
  it 
  the 
  Commission 
  was 
  charged 
  with 
  in- 
  

   creased 
  duties, 
  and 
  during 
  the 
  year 
  now 
  closing 
  Mr. 
  Riley's 
  attention 
  

   has 
  been 
  given 
  to 
  the 
  subject 
  of 
  insects 
  affecting 
  the 
  cotton-plant, 
  while 
  

   Messrs. 
  Packard 
  and 
  Thomas 
  have 
  continued 
  the 
  locust 
  investigation. 
  

   Mr. 
  Packard, 
  with 
  four 
  students 
  and 
  one 
  interpreter, 
  visited 
  portions 
  of 
  

   New 
  Mexico 
  and 
  ascertained 
  the 
  southern 
  portion 
  of 
  the 
  range 
  of 
  the 
  

   gpecies 
  with 
  a 
  view 
  of 
  more 
  accurately 
  mapping 
  out 
  the 
  southern 
  limit 
  of
