  destroyed 
  this 
  summer 
  one-third 
  of 
  the 
  oats 
  and 
  a 
  third 
  of 
  all 
  the 
  gar- 
  

   den 
  produce. 
  We 
  saw 
  them 
  at 
  this 
  place 
  August 
  27, 
  flying 
  in 
  the 
  air 
  

   at 
  an 
  elevation 
  of 
  apparently 
  about 
  500 
  feet; 
  their 
  course 
  was 
  down 
  the 
  

   valley, 
  many 
  taking 
  a 
  southwest 
  course. 
  

  

  Flights 
  of 
  locusts 
  entered 
  Malad 
  Valley 
  late 
  in 
  August 
  from 
  Idaho, 
  

   on 
  the 
  northeast. 
  August 
  10, 
  locusts 
  were 
  observed 
  on 
  the 
  Snake 
  Eiver, 
  

   at 
  or 
  near 
  Taylor's 
  Bridge. 
  

  

  At 
  Franklin, 
  Idaho, 
  none 
  hatched 
  in 
  the 
  spring, 
  but 
  from 
  the 
  middle 
  

   of 
  July 
  until 
  the 
  30th 
  flights 
  arrived 
  from 
  the 
  north, 
  from 
  the 
  region 
  of 
  

   Market 
  Lake 
  and 
  Port 
  Eeuf. 
  I 
  was 
  informed 
  that 
  a 
  large 
  majority 
  of 
  

   those 
  which 
  hatched 
  out 
  last 
  spring 
  went, 
  when 
  fledged, 
  in 
  a 
  northeast 
  

   course 
  (an 
  exception 
  to 
  the 
  ordinary 
  rule, 
  as 
  they 
  usually 
  fly 
  southwest- 
  

   ward), 
  and 
  their 
  progeny 
  are 
  supposed 
  to 
  have 
  returned 
  from 
  their 
  

   breeding- 
  grounds 
  to 
  the 
  northeast. 
  I 
  saw 
  them 
  in 
  abundance 
  August 
  

   27 
  and 
  28, 
  at 
  Franklin 
  — 
  a 
  few 
  in 
  the 
  air, 
  most 
  of 
  them 
  on 
  the 
  ground 
  — 
  

   when 
  they 
  were 
  coupling, 
  but 
  not 
  depositing 
  eggs. 
  They 
  were 
  seen 
  

   eating 
  the 
  leaves 
  of 
  the 
  willow, 
  wild 
  rose, 
  and 
  golden-rods. 
  

  

  Stage 
  passengers 
  from 
  Montana 
  noticed 
  locusts 
  all 
  the 
  way 
  along 
  the 
  

   road 
  from 
  Pleasant 
  Yalley 
  to 
  Franklin. 
  They 
  were 
  observed 
  about 
  the 
  

   18th 
  of 
  July 
  in 
  Gentile 
  Valley, 
  between 
  Franklin 
  and 
  Soda 
  Springs. 
  

   They 
  were 
  seen 
  by 
  Mr. 
  L. 
  Bruner 
  at 
  Soda 
  Springs 
  August 
  18, 
  but 
  no 
  

   eggs 
  were 
  deposited 
  ; 
  about 
  the 
  25th 
  they 
  flew 
  in 
  southeast 
  and 
  south- 
  

   west 
  directions. 
  

  

  A 
  few 
  locusts 
  had 
  recently 
  passed 
  over 
  Salt 
  Lake 
  City, 
  and 
  we 
  noticed 
  

   them 
  in 
  the 
  stubble 
  of 
  a 
  recently 
  harvested 
  wheat 
  field 
  at 
  Lake 
  Point, 
  

   20 
  miles 
  west 
  of 
  the 
  city. 
  According 
  to 
  the 
  Weather 
  Signal 
  report, 
  " 
  vast 
  

   numbers" 
  flew 
  over 
  the 
  city 
  July 
  20, 
  southward. 
  They 
  were 
  reported 
  to 
  

   have 
  extended 
  this 
  season 
  to 
  San 
  Pete, 
  where 
  they 
  had 
  appeared 
  late 
  in 
  

   August, 
  while 
  the 
  settlements 
  at 
  the 
  eastern 
  portion 
  of 
  Wahsatch 
  County 
  

   were 
  visited, 
  about 
  one-half 
  of 
  the 
  wheat 
  crop 
  having 
  been 
  lost. 
  Locusts- 
  

   were 
  also 
  seen 
  by 
  Mr. 
  Bruner 
  at 
  York, 
  70 
  miles 
  south 
  of 
  Salt 
  Lake 
  City, 
  

   and 
  also 
  at 
  Provo, 
  September 
  1. 
  

  

  Flying 
  swarms 
  of 
  grasshoppers 
  have 
  come 
  here 
  of 
  late, 
  and 
  we 
  are 
  unable 
  to 
  learn 
  

   from 
  what 
  direction 
  they 
  have 
  come 
  in 
  every 
  instance. 
  However, 
  they 
  were 
  too 
  late 
  

   to 
  damage 
  our 
  small 
  grain 
  and 
  do 
  no 
  great 
  injury 
  to 
  other 
  crops. 
  They 
  are 
  deposit- 
  

   ing 
  their 
  eggs, 
  and 
  promise 
  a 
  crop 
  for 
  the 
  coming 
  season. 
  These 
  insects 
  are 
  subject 
  to 
  

   die 
  in 
  great 
  numbers, 
  which 
  has 
  often 
  been 
  the 
  means 
  of 
  saving 
  our 
  crops. 
  Even 
  

   now 
  they 
  are 
  dying 
  off 
  quite 
  fast. 
  There 
  is 
  a 
  worm 
  or 
  insect 
  attached 
  to 
  these 
  crea- 
  

   tures 
  sometimes, 
  that 
  is 
  fatal 
  to 
  their 
  vitality.

  From 
  these 
  statements 
  it 
  will 
  be 
  seen 
  that 
  a 
  widely 
  extended 
  but 
  not 
  

   dense 
  swarm, 
  or 
  several 
  swarms, 
  left 
  the 
  Pleasant 
  Valley 
  region 
  on 
  the 
  

   Idaho 
  line 
  about 
  the 
  middle 
  of 
  July 
  and 
  traveled 
  southward, 
  reaching 
  

   Salt 
  Lake 
  City 
  and 
  York 
  by 
  the 
  end 
  of 
  the 
  month. 
  The 
  movement 
  was 
  

   general, 
  the 
  advance 
  guard 
  reaching 
  the 
  southernmost 
  limits 
  of 
  this 
  area 
  

   long 
  before 
  the 
  main 
  body 
  arrived. 
  The 
  emigration 
  beginning 
  so 
  early, 
  

   the 
  breeding-grounds 
  must 
  have 
  been 
  in 
  Central 
  Montana, 
  directly 
  north
