  The 
  regLilar

  of 
  the 
  evening 
  followed: 
  

  

  Peter 
  Bisset: 
  Roses 
  for 
  Garden 
  Decoration 
  (illustrated). 
  

  

  The 
  conditions 
  suitable 
  for 
  best 
  results 
  in 
  growing 
  roses 
  may 
  be 
  summarized. 
  

   The 
  location 
  should 
  be 
  open 
  to 
  the 
  sun 
  from 
  the 
  East 
  and 
  vSouth 
  and 
  protected 
  

   from 
  the 
  West 
  and 
  North 
  by 
  trees, 
  preferably 
  evergreens. 
  The 
  soil 
  must 
  be 
  

   well 
  drained 
  and 
  should 
  be 
  enriched 
  b}'^ 
  the 
  application 
  of 
  well-rotted 
  manure, 
  

   which 
  should 
  be 
  thoroughly 
  spaded 
  in. 
  Four 
  pounds 
  of 
  bone 
  meal 
  should 
  be 
  

   added 
  to 
  each 
  wheelbarrow 
  load 
  of 
  soil. 
  

  

  Concerning 
  varieties; 
  the 
  tea 
  roses 
  are 
  very 
  popular. 
  The 
  hybrid 
  tea 
  is 
  

   probably 
  the 
  rose 
  of 
  the 
  future 
  for 
  American 
  gardens. 
  Maman 
  Cochet, 
  a 
  

   hardy 
  tea 
  rose, 
  is 
  well 
  adapted 
  to 
  the 
  climate 
  of 
  Washington. 
  Of 
  the 
  hybrid 
  

   perpetuals, 
  Baroness 
  de 
  Rotheschild, 
  Mrs. 
  John 
  Laing, 
  Mad 
  Gabriel 
  Luzett, 
  

   Ulrich 
  Brunner, 
  Paul 
  Neyron 
  and 
  Frau 
  Karl 
  Druschke 
  are 
  among 
  the 
  most 
  

   beautiful. 
  The 
  ramblers 
  have 
  their 
  use 
  and 
  can 
  transform 
  an 
  ugly 
  fence 
  or 
  

   unsightly 
  place 
  into 
  an 
  attractive 
  picture. 
  Among 
  the 
  Rugosas, 
  which 
  come 
  

   to 
  us 
  from 
  China, 
  the 
  most 
  attractive 
  are 
  Mrs. 
  George 
  Bruant, 
  Blanch 
  double 
  

   de 
  Coubert, 
  with 
  its 
  semi-double 
  flowers, 
  and 
  Alba 
  semi-plenarj'- 
  and 
  the 
  

   hybrid 
  Conrad 
  F. 
  Meyer. 
  Hugonis 
  is 
  one 
  of 
  the 
  latest 
  arrivals 
  — 
  a 
  new 
  yellow 
  

   rose. 
  

  

  Twenty-four 
  varieties 
  of 
  roses 
  are 
  recommended 
  for 
  general 
  garden 
  culture

  Marsh: 
  Poisonous 
  Wkorled 
  Milkweeds 
  (illustrated). 
  

  

  Asclepias 
  galioides, 
  the 
  whorled 
  milkweed, 
  is 
  one 
  of 
  the 
  most 
  poisonous 
  

   plants 
  which 
  has 
  been 
  investigated. 
  This 
  species 
  is 
  confined 
  to 
  Arizona, 
  

   New 
  Mexico, 
  Colorado 
  and 
  Utah. 
  Two 
  to 
  three 
  ounces 
  of 
  a 
  fresh 
  plant 
  of 
  

   A 
  . 
  galioides 
  will 
  kill 
  a 
  sheep. 
  The 
  effects 
  from 
  eating 
  are 
  violent 
  spasms, 
  then 
  

   death. 
  High 
  temperatures 
  are 
  reached 
  in 
  some 
  animals 
  in 
  acute 
  stages. 
  

   This 
  species 
  is 
  equally 
  poisonous 
  to 
  sheep 
  and 
  horses 
  but 
  is 
  not 
  so 
  poisonous 
  

   to 
  cattle, 
  that 
  is, 
  with 
  equal 
  doses 
  per 
  hundred 
  weight. 
  

  

  There 
  are 
  at 
  least 
  two 
  toxic 
  substances 
  in 
  plants: 
  (1) 
  a 
  narcotic 
  glucoside, 
  

   (2) 
  a 
  spasmodic 
  principle. 
  These 
  have 
  been 
  separated. 
  Capillary 
  congestion 
  

   is 
  caused 
  in 
  the 
  organs 
  of 
  the 
  animal, 
  also 
  degeneration 
  in 
  the 
  organs. 
  This 
  is 
  

   so 
  serious 
  that 
  recovery 
  rarely 
  occurs. 
  

  

  Asclepias 
  pumila 
  is 
  found 
  on 
  the 
  plains 
  in 
  Eastern 
  Colorado. 
  Eating 
  of 
  

   these 
  plants 
  caused 
  same 
  symptoms 
  in 
  the 
  animal 
  as 
  A. 
  galioides, 
  but 
  the 
  

   plant 
  is 
  not 
  so 
  toxic. 
  The 
  dosage 
  is 
  4 
  times 
  as 
  great. 
  

  

  A. 
  verticillata 
  geyeri 
  — 
  Missouri 
  Valley, 
  Iowa. 
  Animals 
  eating 
  this 
  plant 
  

   show 
  same 
  symptoms, 
  but 
  plant 
  is 
  still 
  less 
  toxic. 
  Dosage 
  10 
  times 
  as 
  much. 
  

   It 
  is 
  of 
  little 
  importance 
  as 
  a 
  poisonous 
  plant. 
  Dosage 
  2 
  pounds 
  per 
  100 
  lbs. 
  

   plants.
