  against 
  fire 
  in 
  autumn 
  and 
  then 
  burn 
  the 
  ensuing 
  spring, 
  as 
  we 
  have 
  just 
  

   set 
  forth, 
  could 
  also 
  be 
  mapped 
  out 
  and 
  the 
  maps 
  published 
  for 
  the 
  general 
  

   good 
  and 
  as 
  guides 
  to 
  Congressional 
  action, 
  while 
  an 
  annual 
  report 
  oo 
  

   the 
  locust 
  condition 
  and 
  prospects, 
  to 
  be 
  made 
  part 
  of 
  the 
  report 
  of 
  the 
  

   Signal 
  Bureau, 
  could 
  not 
  fail 
  to 
  greatly 
  interest 
  and 
  benefit 
  the 
  people 
  

   most 
  concerned, 
  and 
  indirectly 
  through 
  them 
  the 
  whole 
  country. 
  

  

  A 
  limited 
  appropriation 
  to 
  the 
  Signal 
  Bureau 
  for 
  this 
  special 
  purpose, 
  

   that 
  would 
  enable 
  the 
  Chief 
  Signal 
  Officer 
  to 
  begin 
  at 
  once 
  the 
  work 
  

   here 
  suggested, 
  under 
  the 
  direction 
  of 
  some 
  competent 
  person 
  or 
  per- 
  

   sons, 
  would, 
  we 
  have 
  no 
  doubt, 
  directly 
  tend 
  to 
  immensely 
  increase 
  the 
  

   practical 
  usefulness 
  of 
  the 
  bureau 
  to 
  the 
  farming 
  community 
  dwelling 
  

   in 
  the 
  vast 
  regions 
  subject 
  to 
  locust 
  injury. 
  Even 
  the 
  observations 
  of 
  

   the 
  individual 
  commissioners 
  and 
  their 
  agents, 
  limited 
  as 
  they 
  have 
  

   necessarily 
  been 
  as 
  compared 
  with 
  those 
  which 
  the 
  Signal 
  Bureau 
  could 
  

   make, 
  have 
  been 
  of 
  great 
  service 
  in 
  permitting, 
  since 
  its 
  organization, 
  

   annual 
  statements 
  and 
  prognostications 
  that 
  have 
  proved 
  correct 
  to 
  a 
  

   remarkable 
  degree 
  ; 
  while, 
  in 
  the 
  event 
  of 
  a 
  repetition 
  of 
  the 
  scenes 
  of 
  

   1873 
  to 
  1877, 
  no 
  one 
  would 
  question 
  the 
  value 
  of 
  daily 
  bulletins, 
  such 
  as 
  

   the 
  Signal 
  Bureau 
  might 
  publish 
  with 
  the 
  increased 
  power 
  we 
  have 
  in- 
  

   dicated, 
  as 
  to 
  the 
  movements 
  and 
  flights 
  of 
  destructive 
  swarms. 
  We 
  

   therefore 
  strongly 
  recommend 
  an 
  appropriation 
  to 
  the 
  Signal 
  Bureau 
  

   for 
  this 
  special 
  purpose.

  the

  PREVENTIVE 
  MEASURES 
  IN 
  THE 
  MOUNTAIN 
  AND 
  PLATEAU 
  AREAS. 
  

  

  The 
  measures 
  to 
  be 
  adopted 
  to 
  prevent 
  locust 
  injury 
  in 
  the 
  more 
  moun- 
  

   tainous 
  area 
  must 
  be 
  essentially 
  the 
  same 
  as 
  those 
  we 
  have 
  recommended 
  

   on 
  the 
  plains; 
  but, 
  as 
  shown 
  in 
  Chapter 
  II 
  (p. 
  24), 
  there 
  is 
  in 
  the 
  inter- 
  

   montane 
  area 
  less 
  land 
  adapted 
  to 
  agricultural 
  pursuits 
  than 
  in 
  the 
  

   plains 
  area, 
  and 
  the 
  chief 
  industry 
  in 
  the 
  former 
  section 
  will 
  always 
  be 
  

   that 
  of 
  mining. 
  Dr. 
  Packard, 
  who 
  has 
  more 
  particularly 
  studied 
  the 
  

   problem 
  in 
  the 
  mountain 
  and 
  plateau 
  areas, 
  gives 
  the 
  following 
  report 
  

   of 
  his 
  views 
  and 
  experience 
  as 
  to 
  the 
  best 
  means 
  of 
  counteracting 
  and 
  

   lessening 
  the 
  injury 
  in 
  the 
  mountains 
  : 
  

  

  "The 
  arable 
  lauds 
  are 
  the 
  bottom 
  lands 
  among 
  the 
  Rocky 
  Mountains, 
  

   the 
  Uintah 
  and 
  Wabsatch 
  Ranges, 
  which 
  lie 
  for 
  the 
  most 
  part 
  between 
  

   the 
  altitudes 
  of 
  about 
  4,000 
  and 
  8,000 
  feet. 
  Above 
  this 
  height, 
  owing 
  to 
  

   summer 
  frosts 
  and 
  cold 
  nights, 
  as 
  well 
  as 
  cold 
  storms, 
  the 
  locusts 
  do 
  

   not 
  flourish 
  in 
  great 
  numbers 
  nor 
  arrive 
  at 
  maturity 
  until 
  two 
  or 
  three 
  

   weeks 
  after 
  those 
  which 
  have 
  hatched 
  out 
  in 
  the 
  regions 
  below 
  have 
  

   become 
  fledged 
  and 
  flown 
  away. 
  

  

  " 
  It 
  is 
  evident 
  then 
  that 
  the 
  breeding 
  grounds 
  of 
  the 
  locust 
  are 
  in 
  those
