  migrations 
  observed 
  in 
  February, 
  1750, 
  during 
  his 
  voyage 
  up 
  the 
  Gam- 
  

   bia. 
  In 
  this 
  case 
  they 
  were 
  brought 
  by 
  a 
  strong 
  east 
  wind, 
  which 
  he 
  

   supposed 
  would 
  ultimately 
  carry 
  them 
  into 
  the 
  sea. 
  He 
  describes 
  them 
  

   as 
  being 
  entirely 
  brown, 
  of 
  the 
  breadth 
  and 
  length 
  of 
  one's 
  finger, 
  and 
  

   the 
  wings 
  much 
  longer 
  than 
  those 
  of 
  any 
  locust 
  he 
  had 
  ever 
  seen 
  before.

  March

  1802,

  From 
  his 
  lan- 
  

   guage 
  and 
  judging 
  by 
  the 
  direction 
  he 
  was 
  moving 
  we 
  presume 
  this 
  was 
  

   a 
  swarm 
  returning 
  northward.

  after 
  giving 
  a 
  vivid 
  description 
  of 
  their 
  ravages 
  in 
  1826, 
  and 
  

   the 
  ineffectual 
  efforts 
  of 
  the 
  natives 
  to 
  stay 
  their 
  progress, 
  remarks 
  

   that 
  — 
  

  

  When 
  a 
  country 
  is 
  not 
  extensive 
  and 
  is 
  bounded 
  by 
  the 
  sea, 
  the 
  scourge 
  is 
  soon 
  over, 
  

   the 
  winds 
  carrying 
  them 
  away 
  like 
  clouds 
  to 
  the 
  watery 
  waste, 
  where 
  they 
  alight 
  to 
  

   rise 
  no 
  more. 
  Thus 
  the 
  immense 
  nights 
  which 
  pass 
  to 
  the 
  south 
  and 
  east 
  rarely 
  re- 
  

   turn, 
  but 
  fresh 
  supplies 
  are 
  always 
  pouring 
  down 
  from 
  the 
  north. 
  All 
  human 
  endeav- 
  

   ors 
  to 
  diminish 
  their 
  numbers 
  would 
  appear 
  like 
  attempting 
  to 
  drain 
  the 
  ocean 
  by 
  a 
  

   pump.

  Jobson's 
  narrative

  he 
  speaks

  the 
  terrible

  brought

  by 
  locust 
  devastations,

  Captain 
  Olapperton 
  130 
  makes 
  no 
  mention 
  

   of 
  locusts, 
  but 
  his 
  faithful 
  servant, 
  Eichard 
  Lander, 
  in 
  his 
  journal, 
  which 
  

   is 
  appended 
  (p. 
  323), 
  incidentally 
  mentions 
  them 
  as 
  an 
  article 
  of 
  food 
  in 
  

   Yariba. 
  Dr. 
  Herman 
  Krauss 
  1SI 
  gives 
  an 
  account 
  of 
  observations 
  of 
  the 
  

   migrations 
  and 
  devastations 
  of 
  A. 
  (ScMstocerca) 
  peregrinum 
  in 
  Senegal 
  

   by 
  Steindachner 
  in 
  the 
  winter 
  of 
  1864. 
  In 
  his 
  enumeration 
  of 
  the 
  

   Acridians 
  of 
  this 
  region 
  this 
  is 
  the 
  only 
  migratory 
  species 
  mentioned. 
  

   He 
  states 
  that 
  Steindachner 
  observed 
  a 
  swarm, 
  evidently 
  of 
  this 
  species, 
  

   flying 
  at 
  sea 
  about 
  200 
  nautical 
  miles 
  from 
  the 
  African 
  coast 
  and 
  distant 
  

   from 
  the 
  Canary 
  Islands. 
  In 
  connection 
  with 
  this 
  well-authenticated 
  

   evidence 
  of 
  flights 
  at 
  sea, 
  we 
  call 
  attention 
  to 
  the 
  remarkable 
  statement 
  

   of 
  Sir 
  Hans 
  Sloane, 
  132 
  that 
  Colonel 
  iSTeedham, 
  who 
  resided 
  for 
  some 
  time 
  

   in 
  Teneriffe, 
  informed 
  him 
  that 
  in 
  1649 
  locusts 
  destroyed 
  all 
  the 
  products 
  

   of 
  that 
  island 
  ; 
  that 
  they 
  were 
  seen 
  to 
  come 
  off 
  from 
  the 
  coast 
  of 
  Bar- 
  

   bary, 
  the 
  wind 
  blowing 
  from 
  thence 
  ; 
  they 
  flew 
  as 
  far 
  as 
  they 
  could, 
  

   then 
  one 
  alighted 
  in 
  the 
  sea 
  and 
  another 
  on 
  it, 
  so 
  that, 
  dropping 
  one 
  

   upon 
  another, 
  in 
  this 
  way 
  they 
  at 
  length 
  made 
  a 
  heap 
  as 
  big 
  as 
  the 
  

   greatest 
  ship 
  above 
  the 
  water, 
  and, 
  as 
  judged, 
  almost 
  as 
  many 
  under. 
  

   Those 
  above 
  water, 
  on 
  the 
  next 
  day 
  after 
  being 
  refreshed 
  by 
  the 
  sun, 
  

   took 
  flight 
  again 
  and 
  came 
  in 
  clouds 
  to 
  the 
  island 
  from 
  whence 
  they 
  

   had 
  perceived 
  them 
  in 
  the 
  air. 
  They 
  were 
  troubled 
  forty 
  years
