  sue 
  the 
  subject 
  further, 
  while 
  they 
  in 
  fact, 
  give 
  weight 
  to 
  

   what 
  is 
  printed 
  above, 
  even 
  to 
  the 
  cursory 
  reader. 
  

  

  As 
  to 
  methods 
  of 
  obtaining 
  books 
  of 
  reference 
  it 
  was 
  

   thought 
  best 
  to 
  buy 
  for 
  the 
  most 
  part, 
  and 
  rely 
  upon 
  borrow- 
  

   ing 
  only 
  when 
  other 
  sources 
  fail. 
  To 
  obtain 
  the 
  books 
  sec- 
  

   ond-hand 
  catalogues 
  should 
  be 
  resorted 
  to. 
  It 
  was 
  suggested 
  

   that 
  the 
  books 
  of 
  each 
  of 
  the 
  station 
  and 
  agricultural 
  college 
  

   libraries 
  be 
  listed 
  and 
  a 
  catalogue 
  put 
  into 
  the 
  hands 
  of 
  all 
  

   station 
  workers. 
  

  

  Ur. 
  Arthur 
  at 
  another 
  time 
  in 
  the 
  sessions 
  spoke 
  at 
  some 
  

   length 
  concerning 
  the 
  exhibition 
  that 
  botanists 
  might 
  make 
  

   at 
  the 
  coming 
  world's 
  (Columbian) 
  fair, 
  and 
  all 
  were 
  glad 
  to 
  

   obtcun 
  the 
  suggestions 
  that 
  the 
  remarks 
  developed. 
  

  

  The 
  second 
  paper 
  was 
  presented 
  by 
  Prof 
  G. 
  F.Atkinson, 
  

   01 
  Alabama, 
  upon 
  "Anthracnose 
  of 
  the 
  cotton," 
  now 
  quite 
  

   destructive 
  in 
  the 
  southern 
  states. 
  It 
  was 
  first 
  observed 
  by 
  

   i^rofessor 
  Atkinson 
  upon 
  the 
  leaf 
  scars 
  of 
  the 
  cotton 
  plant, 
  

   but 
  afterwards 
  upon 
  the 
  bolls. 
  

  

  By 
  means 
  of 
  ink 
  sketches 
  and 
  blackboard 
  drawings 
  the 
  

   species 
  of 
  Colletotrichum, 
  new 
  and 
  recently 
  named 
  by 
  Miss 
  

   ^outhwoi-th 
  C. 
  gossypinag, 
  was 
  fully 
  illustrated 
  in 
  its 
  structure 
  

   'ind 
  habits 
  of 
  growth. 
  The 
  fungus 
  grew 
  readily 
  in 
  solid 
  

   culturesand 
  was 
  propagated 
  with 
  ease 
  upon 
  the 
  cotyledons 
  

   oj 
  seedling 
  cotton 
  plants. 
  It 
  was 
  suggested 
  that 
  in 
  many 
  

   h 
  H 
  ,^^^^^ 
  inoculations 
  might 
  have 
  possibly 
  been 
  successful 
  

   nacl 
  the 
  tender 
  cotyledons 
  been 
  employed 
  in 
  place 
  of 
  the 
  

   more 
  firm 
  dssue 
  of 
  leaf 
  or 
  stem. 
  

  

  -j 
  he 
  same 
  speaker 
  presented 
  the 
  case 
  of 
  the 
  black 
  rust

  cotton, 
  which 
  is 
  a 
  miserable 
  trouble 
  due 
  to 
  more 
  

   jnan 
  one 
  fungus. 
  The 
  ultimate 
  blackness 
  of 
  the 
  "rust," 
  

   so 
  called, 
  is 
  largely 
  due 
  to 
  a 
  Macrosporium 
  or 
  Alternaria,
