﻿LOCUSTS 
  IN 
  NORTHERN 
  AFRICA. 
  49 
  

  

  Western 
  Ocean 
  by 
  a 
  violent 
  hurricane, 
  and 
  the 
  shores 
  were 
  covered 
  with 
  their 
  dead 
  

   bodies. 
  

  

  He 
  says 
  that 
  when 
  the 
  locust 
  is 
  young 
  it 
  is 
  green 
  ; 
  as 
  it 
  grows 
  it 
  as- 
  

   sumes 
  a 
  yellow 
  hue, 
  and 
  lastly 
  becomes 
  brown. 
  The 
  figure 
  given 
  in 
  

   this 
  edition, 
  plate 
  3, 
  is 
  very 
  poor 
  ; 
  but 
  the 
  thorax 
  shows 
  that 
  it 
  is 
  an 
  

   Acridium, 
  and 
  about 
  three 
  inches 
  long. 
  

  

  According 
  to 
  Shaw 
  the 
  locusts 
  in 
  1724 
  began 
  to 
  gather 
  in 
  Barbary 
  

   after 
  a 
  south 
  wind 
  had 
  been 
  some 
  time 
  blowing. 
  Toward 
  the 
  middle 
  of 
  

   April 
  they 
  had 
  so 
  multiplied 
  that 
  they 
  formed 
  immense 
  clouds, 
  darken- 
  

   ing 
  the 
  sun. 
  About 
  the 
  middle 
  of 
  May, 
  when 
  about 
  to 
  deposit 
  their 
  

   eggs, 
  they 
  began 
  to 
  move 
  backwards 
  into 
  the 
  plains 
  of 
  Metidja 
  and 
  

   other 
  adjoining 
  regions, 
  and 
  when 
  the 
  young 
  were 
  fully 
  grown 
  they 
  be- 
  

   came 
  more 
  ravenous 
  and 
  swifter 
  in 
  flight 
  than 
  before. 
  Yet 
  this 
  condi- 
  

   tion 
  lasted 
  not 
  long, 
  when 
  they 
  scattered 
  themselves 
  and 
  laid 
  their 
  eggs 
  ; 
  

   as, 
  moreover, 
  their 
  flight 
  and 
  progress 
  came 
  always 
  from 
  the 
  north 
  (?) 
  so 
  

   it 
  is 
  probable 
  that 
  they 
  found 
  their 
  death 
  in 
  the 
  sea.

  Morocco 
  and 
  

   Taflete 
  are 
  often 
  visited 
  by 
  locust 
  swarms 
  which 
  come 
  in 
  great 
  flocks 
  

   from 
  the 
  south 
  ; 
  they 
  often 
  appear 
  two 
  or 
  three 
  times 
  in 
  the 
  course 
  of 
  

   the 
  year, 
  and 
  their 
  flights 
  are 
  frequently 
  followed 
  by 
  famine, 
  and 
  this 
  

   by 
  pestilence.

  On 
  the 
  23d 
  of 
  September, 
  1701, 
  Forskal 
  observed 
  a 
  swarm 
  come 
  down 
  

   in 
  Cairo. 
  The 
  swarm 
  was 
  composed 
  of 
  the 
  species 
  he 
  termed 
  Gryllus 
  

   gregarius 
  (undoubtedly 
  A. 
  peregrinum). 
  111 
  He 
  saw 
  them 
  again 
  in 
  Jan- 
  

   uary, 
  17G2, 
  flying 
  over 
  the 
  Libyan 
  desert 
  with 
  the 
  southwest 
  wind 
  $ 
  and 
  

   in 
  November, 
  17G2, 
  Niebukr 
  observed 
  them 
  (?) 
  again 
  on 
  his 
  journey 
  from 
  

   the 
  Arabian 
  Gulf 
  to 
  Djedda, 
  where 
  they 
  came 
  up 
  with 
  the 
  wind 
  out 
  of 
  

   the 
  west, 
  across 
  the 
  Gulf, 
  and 
  continued 
  their 
  flight 
  toward 
  the 
  east. 
  113 
  

  

  Browne 
  observed 
  them 
  in 
  Darfur. 
  113 
  Light 
  met 
  with 
  them 
  on 
  the 
  11th 
  

   of 
  May, 
  1814, 
  in 
  destructive 
  swarms 
  at 
  the 
  entrance 
  into 
  Nubia, 
  going 
  

   up 
  the 
  Nile 
  from 
  Egypt, 
  near 
  the 
  island 
  of 
  Phila. 
  114 
  

  

  Burkhardt 
  115 
  mentions 
  finding 
  them 
  at 
  Tacazze, 
  in 
  Nubia, 
  and 
  also 
  at 
  

   the 
  same 
  time 
  in 
  Belad 
  al 
  Taka, 
  in 
  Lower 
  Mareb, 
  which 
  he 
  calls 
  their 
  

   peculiar 
  brooding-place, 
  from 
  whence 
  they 
  issue 
  in 
  destructive 
  migrating 
  

   swarms 
  and 
  lay 
  waste 
  the 
  fields 
  and 
  pastures 
  of 
  Nubia. 
  

  

  In 
  1813 
  they 
  devoured 
  everything 
  in 
  the 
  country 
  of 
  the 
  blacks 
  from 
  

   Besber 
  up 
  to 
  Shendy. 
  Burkhardt 
  affirms 
  that 
  the 
  locusts 
  are 
  at 
  home 
  

   in 
  the 
  whole 
  district 
  of 
  the 
  Nile 
  from 
  Egypt 
  to 
  Sennaar, 
  and 
  in 
  all 
  the 
  

   Nubian 
  desert 
  ; 
  that 
  all 
  the 
  swarms 
  which 
  he 
  saw 
  in 
  Upper 
  Egypt 
  came 
  

   from 
  the 
  north, 
  and 
  that 
  the 
  Nubians 
  declared 
  they 
  came 
  from 
  Upper 
  

   Egypt 
  to 
  them
