  ical 
  work 
  in 
  the 
  stations 
  was 
  emphasized, 
  and 
  he 
  hoped 
  to 
  

   be 
  able 
  to 
  assist 
  the 
  station 
  botanists 
  more 
  and 
  more. 
  

  

  Chairman 
  Tracy 
  assured 
  the 
  secretary 
  that 
  the 
  warmest 
  

   sympathy 
  existed 
  between 
  the 
  station 
  botanists 
  and 
  the 
  De- 
  

   partment 
  at 
  Washington 
  and 
  stated 
  that 
  a 
  great 
  impetus 
  had 
  

   been 
  given 
  to 
  botanical 
  science 
  in 
  this 
  country 
  within 
  the 
  

   past 
  few 
  years. 
  

  

  "Fungicides" 
  was 
  the 
  subject 
  of 
  a 
  paper 
  by 
  D. 
  G. 
  Fair- 
  

   child, 
  of 
  the 
  Division 
  of 
  Vegetable 
  Pathology 
  at 
  Washington. 
  

   A 
  history 
  of 
  the 
  subject 
  was 
  followed 
  by 
  a 
  classification 
  of 
  the 
  

   l^rge 
  number 
  of 
  different 
  substances 
  employed 
  as 
  fungicides. 
  

   Ihe 
  theorjr 
  of 
  fungicidal 
  action 
  was 
  explained 
  and 
  many 
  

   mixtures 
  were 
  named 
  that 
  had 
  proved 
  effective, 
  and 
  several 
  

   others 
  were 
  shown 
  that 
  combined 
  the 
  good 
  qualities 
  of 
  a 
  

   hmgicide, 
  namely, 
  effectiveness, 
  ease 
  of 
  application 
  and 
  

   cheapness. 
  These 
  latter 
  will 
  be 
  tested 
  the 
  coming 
  year, 
  and 
  

   as 
  some 
  of 
  them 
  are 
  low 
  priced, 
  made 
  adhesive 
  by 
  "the 
  addi- 
  

   tion 
  of 
  molasses, 
  and 
  contain 
  the 
  required 
  ingredients

   "^ay 
  be 
  expected 
  for 
  them.

  Being 
  dissatisfied 
  with

  made 
  a
