  COMMISSION. 
  

  

  of 
  Minnesota 
  late 
  in 
  the 
  summer, 
  one 
  of 
  them 
  passing 
  into 
  the 
  northwest- 
  

   ern 
  corner 
  of 
  Iowa. 
  

  

  In 
  Nebraska 
  small 
  local 
  nights, 
  going 
  in 
  different 
  directions, 
  were 
  

   seen 
  at 
  Schuyler, 
  and 
  a 
  small 
  brood 
  hatched 
  out 
  twenty 
  miles 
  west 
  of 
  

   Lincoln, 
  while 
  Omaha 
  was, 
  about 
  the 
  middle 
  of 
  June, 
  visited 
  by 
  a 
  few 
  

   locusts 
  from 
  the 
  south. 
  

  

  In 
  Indian 
  Territory 
  a 
  swarm 
  of 
  considerable 
  extent 
  visited 
  Fort 
  Sill 
  

   and 
  deposited 
  eggs, 
  but 
  nothing 
  was 
  heard 
  from 
  them 
  the 
  succeeding 
  

   year. 
  In 
  Kansas, 
  Dodge 
  Oity 
  was 
  visited 
  in 
  September. 
  There 
  were 
  

   also 
  small 
  local 
  nights 
  in 
  Barton 
  and 
  Sumner 
  Counties, 
  Kansas. 
  

  

  A 
  larger 
  number 
  of 
  flights 
  from 
  the 
  northwest 
  occurred 
  in 
  Dakota, 
  

   extending 
  from 
  the 
  neighborhood 
  of 
  Bismarck 
  into 
  Montana, 
  and 
  in 
  

   June 
  Bismarck 
  was 
  visited 
  by 
  a 
  swarm 
  from 
  the 
  southeast. 
  

  

  While 
  in 
  Colorado 
  the 
  locust 
  annually 
  breeds 
  in 
  small 
  numbers 
  on 
  

   the 
  mountains, 
  above 
  an 
  elevation 
  of 
  about 
  8,000 
  feet, 
  only 
  s 
  a 
  few 
  local 
  

   flights 
  were 
  observed, 
  viz, 
  at 
  Summit, 
  in 
  Estes 
  Park, 
  and 
  at 
  White 
  

   Eiver 
  Agency 
  ; 
  also 
  along 
  the 
  Upper 
  Bear 
  Eiver 
  Valley, 
  where 
  eggs 
  

   were 
  deposited. 
  The 
  progeny 
  of 
  the 
  latter 
  swarm 
  went 
  east 
  the 
  next 
  

   summer 
  (1879), 
  passing 
  over 
  Denver 
  and 
  alighting 
  a 
  few 
  miles 
  to 
  the 
  

   southeast. 
  A 
  small 
  swarm 
  was 
  observed 
  going 
  in 
  a 
  northwesterly 
  course 
  

   near 
  Las 
  Animas, 
  on 
  the 
  Topeka, 
  Atchison 
  and 
  Santa 
  Fe 
  Eailroad. 
  

  

  In 
  Wyoming 
  a 
  large 
  swarm 
  at 
  the 
  end 
  of 
  July 
  flew 
  in 
  an 
  easterly 
  

   direction 
  over 
  Como, 
  and 
  were 
  supposed 
  to 
  Lave 
  come 
  from 
  the 
  Wind 
  

   Eiver 
  and 
  Bighorn 
  region, 
  while 
  a 
  few 
  flew 
  over 
  Cheyenne. 
  The 
  north- 
  

   western 
  portion 
  of 
  the 
  Territory 
  was 
  visited 
  by 
  swarms 
  from 
  the 
  north- 
  

   east 
  which 
  flew 
  southwest. 
  

  

  About 
  Taos 
  and 
  Santa 
  Fe, 
  in 
  New 
  Mexico, 
  as 
  has 
  already 
  been 
  stated, 
  

   considerable 
  local 
  damage 
  ensued 
  and 
  young 
  hatched, 
  but 
  none 
  were 
  to 
  

   be 
  seen 
  in 
  the 
  year 
  succeeding. 
  

  

  Utah, 
  in 
  1878, 
  was 
  freer 
  from 
  locusts 
  than 
  in 
  the 
  year 
  previous, 
  but 
  

   still 
  the 
  farmers 
  in 
  Summit 
  County 
  lost 
  nearly 
  half 
  their 
  wheat 
  crop 
  

   from 
  the 
  young, 
  which 
  hatched 
  out 
  in 
  large 
  numbers 
  and, 
  on 
  becoming 
  

   fledged, 
  flew 
  in 
  a 
  northerly 
  course 
  to 
  Morgan 
  County. 
  Flights 
  entered 
  

   Malade 
  and 
  Cache 
  Valleys 
  late 
  in 
  August, 
  arriving 
  from 
  Idaho, 
  and 
  

   locusts 
  were 
  seen 
  at 
  various 
  points, 
  late 
  in 
  July 
  and 
  during 
  August, 
  be- 
  

   tween 
  Franklin 
  and 
  the 
  Montana 
  line, 
  near 
  Pleasant 
  Valley. 
  The. 
  

   breeding-ground 
  of 
  these 
  locusts 
  was 
  in 
  Central 
  Montana, 
  as 
  indicated 
  

   on 
  Map 
  3. 
  In 
  Montana, 
  also, 
  flights 
  arrived 
  in 
  the 
  central 
  arable 
  part 
  

   of 
  the 
  Territory 
  from 
  the 
  Yellowstone 
  Valley 
  on 
  the 
  east 
  and 
  from 
  Brit- 
  

   ish 
  America 
  on 
  the 
  north.

  FLIGHTS 
  IN 
  1879. 
  

  

  The 
  flights 
  east 
  of 
  the 
  Permanent 
  Eegion 
  were 
  on 
  the 
  whole 
  fewer 
  this 
  

   year 
  than 
  in 
  1878, 
  as 
  may 
  be 
  seen 
  by 
  an 
  inspection 
  of 
  Map 
  No. 
  4 
  ; 
  though 
  

   in 
  Nebraska, 
  Iowa, 
  Minnesota, 
  and 
  Dakota 
  there 
  were 
  more 
  extensive
