  being

  of 
  the

  two,

  As 
  regards 
  C.

  the 
  author 
  

   finds 
  that 
  it 
  undergoes 
  an 
  alternation 
  of 
  hosts 
  between 
  Picea 
  orientalis 
  

   (not 
  P. 
  excelsa, 
  as 
  had 
  been 
  held 
  before) 
  and 
  Abies 
  ; 
  while 
  C. 
  piceae, 
  

   which 
  until 
  recently 
  was 
  taken 
  to 
  be 
  the 
  same 
  as 
  C. 
  nusslini, 
  passes 
  its 
  

   whole 
  life-cycle 
  on 
  Abies. 
  Chermes 
  pini 
  was 
  thought 
  to 
  reproduce 
  

   indefinitely 
  by 
  parthenogenesis 
  on 
  the 
  pine 
  ; 
  but 
  sexual 
  reproduction 
  

   taking 
  place 
  on 
  Picea 
  excelsa, 
  has 
  been 
  discovered 
  by 
  Cholodkovsky. 
  

   Galls 
  of 
  a 
  species 
  of 
  Chermes, 
  now 
  thought 
  to 
  be 
  C. 
  pini, 
  have 
  been 
  

   found 
  on 
  Picea 
  orientalis 
  in 
  the 
  south 
  of 
  Europe 
  ; 
  recently, 
  in 
  the 
  

   neighbourhood 
  of 
  Paris 
  where 
  P. 
  orientalis 
  is 
  abundant, 
  the 
  author 
  was 
  

   able 
  to 
  trace 
  the 
  sexual 
  generation 
  of 
  C. 
  pini 
  on 
  this 
  tree. 
  C. 
  strobi, 
  

   which 
  has 
  been 
  imported 
  from 
  America, 
  multiplies 
  in

  ex- 
  

   clusively 
  by 
  parthenogenesis.

  This 
  booklet 
  deals 
  very 
  completely 
  with 
  bee-keeping 
  in 
  Tennessee. 
  

   Bee-moth 
  is 
  stated 
  to 
  be 
  the 
  chief 
  of 
  the 
  troubles 
  of 
  the 
  bee-keeper, 
  

   which, 
  in 
  diminishing 
  degree 
  of 
  importance, 
  comprise 
  paralysis, 
  foul- 
  

   brood, 
  ants, 
  cockroaches, 
  toads, 
  mice, 
  and 
  birds. 
  The 
  presence 
  of 
  

   bee-moth 
  impHes 
  carelessness, 
  for 
  it 
  never 
  attacks 
  a 
  strong 
  vigorous 
  

   colony.

  The 
  female 
  moth 
  {Archips 
  argyrospila, 
  Walk.) 
  deposits 
  her 
  eggs 
  in 
  

   compact 
  oval 
  clusters 
  of 
  from 
  twenty-five 
  to 
  more 
  than 
  one 
  hundred. 
  

   The 
  first 
  larvae 
  emerge 
  with 
  the 
  bursting 
  of 
  the 
  apple 
  leaf 
  buds, 
  and 
  

   when 
  the 
  blossom 
  buds 
  begin 
  to 
  show 
  their 
  pink 
  colour 
  the 
  eggs 
  are 
  

   nearly 
  all 
  hatched. 
  The 
  apple 
  is 
  chiefly 
  attacked. 
  Plum, 
  cherry, 
  and 
  

   pear 
  trees 
  sufier 
  less, 
  and 
  the 
  peach 
  is 
  practically 
  immune 
  ; 
  but 
  when 
  

   food 
  is 
  scarce 
  the 
  larvae 
  will 
  attack 
  any 
  green 
  foHage. 
  The 
  history 
  

   of 
  the 
  leaf-roller 
  in 
  the 
  Canon 
  City 
  Section 
  is 
  then 
  given 
  by 
  A. 
  S. 
  

   Taylor. 
  First 
  noticed 
  in 
  the 
  spring 
  of 
  1908, 
  its 
  ravages 
  rapidly 
  

   increased, 
  and 
  according 
  to 
  data 
  available 
  in 
  August 
  1912, 
  the 
  crop 
  

   on 
  the 
  south 
  side 
  of 
  the 
  river 
  was 
  damaged 
  fully 
  85 
  per 
  cent. 
  The 
  

   north 
  side 
  promised 
  nearly 
  a 
  full 
  crop, 
  but 
  was 
  found 
  to 
  be 
  badly 
  

   damaged 
  at 
  picking 
  time. 
  The 
  eggs 
  were 
  not 
  destroyed 
  by 
  very 
  

   strong 
  solutions 
  of 
  lime 
  and 
  sulphur 
  used 
  in 
  1910 
  and 
  1911 
  ; 
  7 
  lb. 
  

   of 
  lead 
  arsenate 
  in 
  100 
  gallons 
  of 
  water 
  could 
  not 
  save 
  the 
  fruit, 
  though 
  

   it 
  saved 
  some 
  of 
  the 
  foliage 
  ; 
  miscible 
  oil 
  seems 
  to 
  have 
  solved 
  this 
  

   serious 
  problem 
  at 
  last. 
  

  

  The 
  main 
  report 
  then 
  continues 
  with 
  a 
  comprehensive 
  list 
  of 
  in- 
  

   secticides, 
  tables 
  of 
  the 
  insectary 
  experiments 
  carried 
  out 
  with 
  them, 
  

   and 
  detailed 
  notes 
  to 
  supplement 
  the 
  tables. 
  These 
  experiments 
  

   resulted 
  in 
  the 
  following 
  conclusions 
  :
