  gration 
  of 
  our 
  Weeds," 
  begs 
  another 
  favor 
  of 
  the 
  readers 
  of 
  the 
  Ga/ftte. 
  

   It 
  is 
  to 
  kindly 
  report 
  to 
  the 
  undersigned 
  the 
  advent 
  (or 
  disappearance) 
  

   of 
  any 
  weed 
  in 
  their 
  section 
  o! 
  the 
  country 
  within 
  the 
  past 
  five, 
  ten 
  or 
  

   more 
  years, 
  and 
  if 
  possible 
  the 
  method 
  by 
  means 
  of 
  which 
  the 
  species 
  be- 
  

   came 
  introduced 
  (or 
  eliminated). 
  In 
  the 
  preparation 
  of 
  such 
  a 
  paper 
  it 
  

   is 
  not 
  enough 
  to 
  go 
  to 
  the 
  books. 
  The 
  personal 
  observations 
  of 
  the 
  many 
  

   active 
  botanists 
  of 
  to-day 
  are 
  necessary 
  in 
  order 
  to 
  bring 
  the 
  treatment 
  

   down 
  to 
  date. 
  With 
  such 
  assistance 
  there 
  will 
  be 
  no 
  excuse 
  if 
  the 
  com- 
  

   piler 
  fails 
  to 
  present 
  matter 
  of 
  permanent 
  value 
  to 
  both

  of

  and

  I 
  notice 
  in 
  the 
  November 
  Gazette 
  (p. 
  291) 
  that 
  Professor 
  C. 
  B. 
  At- 
  

   well 
  makes 
  a 
  singular 
  remark 
  on 
  Nostoc 
  pruniforme 
  with 
  reference 
  to 
  

   my 
  Fresh 
  Water 
  Algae, 
  saying 
  that 
  when 
  my 
  volume 
  appeared 
  this 
  nostoc 
  

   was 
  not 
  mentioned. 
  The 
  fact 
  is, 
  more 
  is 
  said 
  of 
  this 
  species 
  than 
  of 
  an 
  v 
  

   other. 
  Prof. 
  Atwell

  to 
  re-read
