  The 
  state 
  of 
  New 
  York 
  has 
  for 
  the 
  last 
  three 
  years 
  maintained 
  a 
  corps 
  

   of 
  inspectors 
  for 
  the 
  purpose 
  of 
  examining 
  all 
  nursery 
  stock 
  for 
  the 
  pres- 
  

   ence 
  of 
  this 
  and 
  other 
  injurious 
  pests. 
  Many 
  exceedingly 
  valuable 
  facts 
  

   have 
  been 
  gained 
  in 
  this 
  manner, 
  and 
  the 
  following 
  comments 
  on 
  the 
  

   food 
  plants 
  of 
  the 
  San 
  Jose 
  scale 
  in 
  New 
  York 
  state 
  by 
  G. 
  G. 
  Atwood, 
  

   now 
  in 
  immediate 
  charge 
  of 
  this 
  work, 
  are 
  based 
  on 
  considerable 
  experi- 
  

   ence. 
  The 
  plants 
  are 
  grouped 
  in 
  three 
  sections.

  The 
  following 
  is 
  a 
  list 
  of 
  plants 
  on 
  which 
  the 
  San 
  Jose 
  scale 
  has 
  

   been 
  found, 
  though 
  in 
  very 
  small 
  quantity, 
  and 
  no 
  injury 
  has 
  resulted 
  

   from 
  its 
  presence, 
  and 
  it 
  is 
  probable 
  that 
  it 
  will 
  not 
  live 
  over 
  winter 
  on 
  

   them 
  in 
  this 
  state, 
  and 
  it 
  is 
  not 
  likely 
  to 
  breed 
  freely 
  on 
  them: 
  alder, 
  

   amalanchier, 
  ash, 
  birch, 
  blackberry, 
  chestnut, 
  dewberry, 
  dogwood 
  (flow- 
  

   ering), 
  elaeagnus, 
  eucalyptus, 
  fig, 
  grape, 
  honeysuckle, 
  horse-chestnut, 
  

   kerria, 
  maples 
  (silver 
  and 
  wiers), 
  milkweed, 
  mountain 
  laurel, 
  pepper- 
  

   grass, 
  poplars 
  (except 
  aspen), 
  quack 
  grass, 
  quince 
  (edible), 
  raspberry, 
  

   rhus, 
  spiraeas 
  (some 
  species), 
  strawberries, 
  walnut 
  (English), 
  and 
  to 
  this 
  

   list 
  I 
  would 
  add 
  cherry 
  commonly 
  called 
  " 
  sour," 
  including 
  such 
  varieties 
  

   as 
  Richmond, 
  Morello, 
  etc.

  The 
  following 
  is 
  a 
  list 
  of 
  plants 
  on 
  which 
  the 
  San 
  Jose 
  scale 
  finds 
  

   suitable 
  food, 
  and 
  therefore 
  spreads 
  rapidly, 
  causing 
  serious 
  injury: 
  

   acacia, 
  akebia, 
  apple, 
  peach, 
  pear, 
  plum, 
  cherry 
  (sweet), 
  apricot, 
  necta- 
  

   rine, 
  almond 
  (flowering), 
  cherry 
  (flowering, 
  Rocky 
  mountain 
  dwarf 
  and 
  

   Japan), 
  cotoneaster, 
  Crataegus, 
  currants 
  (red, 
  white 
  and 
  flowering), 
  elm 
  

   (Enghsh), 
  gooseberry, 
  Japan 
  quince, 
  mountain 
  ash, 
  peach 
  (flowering), 
  

   prunes 
  (flowering 
  and 
  pissardi), 
  Osage 
  orange, 
  snowberry 
  and 
  willow 
  

   (many 
  species). 
  

  

  It 
  is 
  noticed 
  that 
  this 
  latter 
  Hst 
  is 
  not 
  very 
  long, 
  but 
  unfortunately 
  it 
  in- 
  

   cludes 
  the 
  principal 
  orchard 
  trees 
  and 
  currants. 
  In 
  some 
  sections 
  it 
  

   looks 
  as 
  if 
  the 
  San 
  Jose 
  would 
  not 
  thrive 
  on 
  Kieffer 
  pears, 
  while 
  else- 
  

   where 
  it 
  proves 
  very 
  destructive 
  to 
  this 
  variety. 
  

  

  Distribution. 
  This 
  pest 
  is 
  widely 
  distributed 
  in 
  the 
  United 
  States, 
  

   having 
  been 
  recorded 
  from 
  ;^6 
  states 
  and 
  territories, 
  besides 
  the 
  District 
  

   of 
  Columbia. 
  It 
  has 
  also 
  been 
  found 
  in 
  a 
  number 
  of 
  localities 
  in 
  

   Ontario 
  (Can.)
