﻿LOCUSTS 
  IN 
  CAPE 
  COLONY. 
  

  

  [71] 
  

  

  swarm 
  after 
  swarm, 
  and 
  saved 
  a 
  great 
  part 
  of 
  the 
  district 
  besides 
  his 
  

   owu 
  crops 
  and 
  pasturage. 
  The 
  killing 
  of 
  the 
  locusts 
  was 
  effected, 
  as 
  in 
  

   Eajpootana, 
  by 
  covering 
  those 
  collected 
  with 
  earth 
  and 
  stamping 
  the 
  

   earth 
  down. 
  I 
  believe 
  that 
  glazed 
  earthenware 
  tiles 
  would 
  form 
  an 
  

   effective 
  armor 
  for 
  walls. 
  To 
  some 
  rough 
  walls 
  metal 
  could 
  not 
  be 
  

   affixed 
  flat, 
  and 
  for 
  that 
  reason, 
  and 
  also 
  because 
  it 
  would 
  be 
  well, 
  as 
  

   soon 
  as 
  the 
  plague 
  is 
  over, 
  to 
  remove 
  the 
  metal 
  and 
  pack 
  it 
  away 
  for 
  

   future 
  service, 
  I 
  suggested 
  that 
  blocks 
  should 
  at 
  certain 
  distances, 
  

   about 
  7 
  feet 
  (if 
  the 
  tin 
  strips 
  should 
  be 
  8 
  feet 
  long), 
  be 
  built 
  into 
  the 
  walls, 
  

   so 
  that 
  staples 
  could 
  be 
  inserted 
  into 
  them 
  to 
  support 
  a 
  contrivance 
  of 
  

   iron, 
  shaped 
  like 
  the 
  following 
  diagram, 
  B 
  to 
  be 
  inserted 
  into 
  the 
  staple, 
  

  

  A 
  to 
  support 
  the 
  ends 
  of 
  two 
  strips 
  of 
  the 
  6 
  or 
  8 
  feet 
  tin, 
  the 
  fold 
  between 
  

   A 
  and 
  B 
  to 
  be 
  3 
  inches 
  long. 
  The 
  staple 
  and 
  block 
  would 
  remain 
  in 
  the 
  

   wall, 
  and 
  the 
  iron 
  contrivance 
  of 
  support 
  for 
  the 
  tin 
  and 
  the 
  sheets 
  of 
  

   tin 
  could 
  safely 
  be 
  stored 
  away 
  after 
  use. 
  The 
  tin 
  would 
  thus 
  be 
  safe 
  

   from 
  theft, 
  and 
  damage 
  from 
  cattle 
  rubbing 
  against 
  it. 
  I 
  calculated 
  that 
  

   the 
  last 
  swarm 
  we 
  had 
  in 
  this 
  district 
  of 
  marching 
  locusts, 
  then 
  pretty 
  

   large 
  already, 
  would 
  have 
  formed 
  a 
  column 
  of 
  one 
  yard 
  square 
  and 
  20 
  

   miles 
  high. 
  I 
  am 
  fully 
  satisfied 
  that 
  a 
  force 
  (not 
  at 
  all 
  numerous) 
  should 
  

   be 
  called 
  out 
  to 
  attack 
  marching 
  locusts 
  when 
  they 
  appear, 
  and 
  that 
  a 
  

   very 
  small 
  force 
  with 
  a 
  few 
  strips 
  of 
  tin 
  would 
  destroy 
  any 
  invasion 
  of 
  

   locusts.

  A, 
  the 
  sloping

  strip. 
  B, 
  tho 
  

   block. 
  The 
  sloping 
  tin 
  strip 
  would 
  act 
  just 
  as 
  

   weU 
  at 
  C. 
  

  

  The 
  tin 
  being 
  placed 
  in 
  a 
  projecting 
  position 
  would 
  add 
  to 
  the 
  difficulty 
  of 
  a 
  locust 
  

   passing 
  over 
  it, 
  or 
  rather 
  would 
  wholly 
  prevent 
  its 
  ascent.
