  Locusts 
  after 
  obtaining 
  their 
  full-sized 
  wings 
  begin 
  to 
  pair 
  ; 
  the 
  male 
  

   dies 
  early, 
  the 
  female 
  flies 
  until 
  ready 
  to 
  lay 
  or 
  deposit 
  her 
  eggs. 
  She 
  

   bores 
  her 
  tail 
  into 
  the 
  ground 
  till 
  all 
  that 
  remains 
  of 
  her 
  above 
  ground 
  

   is 
  her 
  head, 
  shoulders, 
  and 
  wings; 
  her 
  body 
  then 
  breaks 
  off, 
  the 
  eggs 
  

   remaining 
  in 
  the 
  natural 
  sheath. 
  The 
  young 
  locusts 
  do 
  not 
  appear 
  until 
  

   rain 
  falls, 
  rain 
  seemingly 
  being 
  necessary 
  towards 
  hatching; 
  but 
  then 
  

   there 
  must 
  be, 
  apparently, 
  a 
  favorable 
  season 
  also, 
  as 
  it 
  is 
  believed 
  that 
  

   eggs 
  remain 
  in 
  the 
  ground 
  unchanged 
  for 
  years, 
  although 
  rains 
  tail. 
  Boers 
  

   have 
  told 
  me 
  that 
  one 
  rain 
  sometimes 
  only 
  vivifies 
  some 
  of 
  the 
  eggs 
  of 
  one 
  

   individual, 
  and 
  that 
  the 
  remainder 
  of 
  the 
  eggs 
  only 
  are 
  affected 
  by 
  a 
  later, 
  

   more 
  penetrating 
  rain. 
  Where 
  the 
  country 
  is 
  open, 
  and 
  there 
  are 
  hills 
  to 
  

   ascend 
  to 
  observe 
  from, 
  the 
  congregated 
  swarms 
  of 
  young 
  locusts 
  are 
  

   easily, 
  at 
  early 
  morn, 
  perceived 
  at 
  a 
  distance, 
  at 
  first 
  in 
  black 
  and 
  after- 
  

   ward 
  in 
  brownish 
  patches, 
  as 
  each 
  swarm 
  congregates 
  together 
  at 
  night. 
  

   In 
  marching 
  the 
  locusts 
  advance 
  with 
  one 
  or 
  more 
  points, 
  so 
  that 
  it 
  is 
  

   easy 
  to 
  lay 
  a 
  trap 
  for 
  them 
  to 
  walk 
  into, 
  and 
  the 
  less 
  they 
  are 
  dis- 
  

   turbed 
  by 
  driving 
  the 
  better. 
  Young 
  locusts 
  cast 
  their 
  skins 
  at 
  least 
  

   twice 
  before 
  they 
  obtain 
  wings."

  The 
  best 
  mode 
  of 
  protection 
  against 
  flying 
  locusts 
  must 
  greatly 
  de- 
  

   pend 
  upon 
  the 
  state 
  of 
  the 
  wind 
  and 
  the 
  nature 
  of 
  the 
  locality. 
  When 
  

   chased 
  by 
  the 
  different 
  kinds 
  of 
  locust-birds 
  they 
  endeavor 
  to 
  evade 
  

   the 
  birds, 
  so 
  it 
  is 
  useful 
  to 
  imitate 
  birds 
  by 
  attaching 
  strips 
  of 
  white 
  

   calico, 
  like 
  wings, 
  to 
  lines 
  stretched 
  between 
  poles, 
  and, 
  to 
  keep 
  them 
  

   fluttering, 
  either 
  by 
  hand 
  or 
  by 
  the 
  force 
  of 
  the 
  wind. 
  

  

  Telescopic 
  poles 
  for 
  the 
  lines 
  would 
  probably 
  be 
  of 
  much 
  benefit, 
  as 
  

   probably 
  therewith 
  the 
  locusts 
  would 
  rise 
  high 
  and 
  pass 
  over 
  the 
  crops. 
  

   Numerous 
  small 
  kites, 
  if 
  there 
  was 
  wind 
  to 
  support 
  them, 
  or 
  small 
  

   balloons 
  to 
  support 
  high 
  lines, 
  would 
  also 
  be 
  useful.

  scourge

  devastating

  Locusts

  1878-'79. 
  

  

  In 
  our 
  first 
  report 
  some 
  account 
  was 
  given 
  of 
  the 
  recent 
  appearance 
  

   of 
  locusts 
  in 
  these 
  tropical 
  moist 
  islands. 
  It 
  appears 
  by 
  the 
  following 
  

   newspaper 
  extract 
  that 
  the 
  distress 
  was 
  renewed 
  in 
  1878 
  and 
  1879 
  : 
  

  

  The 
  Philippine 
  Islands 
  are 
  experiencing 
  a 
  severe 
  drouth, 
  which 
  is 
  aggravated 
  by 
  the 
  

   ravages 
  of 
  locusts, 
  and 
  there 
  is 
  great 
  suffering 
  among 
  the 
  people, 
  many 
  of 
  whom 
  are 
  

   obliged 
  to 
  subsist 
  on 
  roots.
