  latter 
  is 
  considered 
  to 
  have 
  checked 
  the 
  epidemic 
  of 
  cutworms 
  pre- 
  

   valent 
  in 
  1912 
  in 
  the 
  Kootenay, 
  for 
  but 
  little 
  damage 
  resulted 
  in 
  1913. 
  

   The 
  pests 
  injured 
  nearly 
  every 
  cultivated 
  plant, 
  including 
  green 
  grain. 
  

   Vegetable 
  gardens 
  and 
  orchards 
  suffered 
  most, 
  while 
  they 
  w^ere 
  very 
  

   destructive 
  in 
  cabbage, 
  turnips, 
  and 
  tomato 
  fields, 
  and 
  damaged 
  

   strawberry 
  beds 
  extensively. 
  The 
  most 
  common 
  varieties 
  are 
  the 
  

   red-backed 
  (Paragrotis 
  ochrogaster), 
  the 
  greasy 
  (Agrotis 
  ypsilon), 
  the 
  

   variegated 
  {Peridroma 
  saucia, 
  Lycophotia 
  margaritosa), 
  and 
  the 
  zebra 
  

   caterpillars 
  (Mamestra 
  canadensis, 
  Polia 
  nevadae). 
  The 
  Canadian 
  

   list 
  might 
  be 
  extended 
  to 
  include 
  the 
  following 
  : 
  — 
  yellow-headed 
  

   (Hadena 
  arctica, 
  Aplectoides 
  speciosa), 
  spotted 
  (Noctua 
  c-nigrum), 
  

   brown 
  {NepJielades 
  minians), 
  W-marked 
  {Noctua 
  clandestina, 
  unicolor), 
  

   cominonstiii^ed{Euxoatessellata),whitec\imhmg{Carneades[Lycophotia] 
  

   scandens), 
  spotted 
  legged 
  {Porosagrotis 
  vetiista), 
  and 
  dingy 
  (FeUia 
  

   subgothica). 
  Poison 
  bait 
  is 
  possibly 
  the 
  best 
  all-round 
  material 
  for 
  

   control. 
  Use 
  1 
  lb. 
  Paris 
  green, 
  50 
  lb. 
  bran, 
  about 
  3 
  lb. 
  sugar. 
  First 
  

   moisten 
  the 
  bran 
  a 
  little, 
  then 
  add 
  the 
  Paris 
  green 
  and 
  mix 
  well, 
  then 
  

   add 
  the 
  sugar 
  as 
  sweetened 
  water. 
  The 
  bait 
  should 
  be 
  considerably 
  

   sweeter 
  than 
  the 
  plants 
  the 
  larvae 
  are 
  feeding 
  on. 
  About 
  25-50 
  lb. 
  

   should 
  suffice 
  for 
  an 
  acre 
  of 
  vegetables 
  and 
  fruit. 
  Fruit 
  trees 
  only 
  

   wall 
  require 
  much 
  less. 
  Keep 
  the 
  mixture 
  well 
  away 
  from 
  the 
  trees 
  

   or 
  plants 
  to 
  prevent 
  them 
  from 
  being 
  injured. 
  Tanglefoot 
  has 
  given 
  

   good 
  results 
  in 
  the 
  case 
  of 
  fruit 
  trees 
  and 
  larger 
  plants, 
  and 
  banding 
  

   with 
  cotton 
  batten 
  is 
  also 
  useful. 
  Running 
  chickens 
  are 
  very 
  effec- 
  

   tive 
  in 
  an 
  orchard. 
  Cultivation 
  methods 
  assist 
  considerably. 
  Cover 
  

   crops 
  left 
  over 
  winter 
  as 
  a 
  protection 
  harbour 
  the 
  larvae, 
  the 
  eggs 
  of 
  

   which 
  might 
  be 
  destroyed 
  if 
  the 
  sowing 
  of 
  the 
  crop 
  were 
  delayed 
  a 
  

   little 
  to 
  allow 
  of 
  this.

  The

  summarises 
  his 
  remarks 
  by 
  stating 
  that 
  there 
  is 
  a 
  chance 
  

   of 
  imported 
  birds 
  becoming 
  a 
  pest 
  and 
  upsetting 
  the 
  balance 
  of 
  nature, 
  

   and 
  that 
  scientific 
  societies 
  should 
  protest

  being 
  

   granted 
  for 
  the 
  introduction 
  of 
  any 
  exotic 
  birds

   either 
  from 
  aesthetic 
  or 
  economic 
  considerations. 
  At 
  the 
  close 
  of 
  the 
  

   ensuing 
  discussion 
  it 
  was 
  moved

  " 
  That 
  this

   in

  of 
  recent 
  researches 
  into 
  the 
  economic 
  value
