  when 
  the 
  clock 
  is 
  running, 
  revolve 
  once 
  an 
  hour 
  on 
  a 
  horizontal 
  axis 
  

   this 
  will 
  do 
  away 
  with 
  the 
  effect 
  of 
  gravity 
  in 
  determining 
  the 
  direction 
  

   of 
  growth 
  in 
  the 
  germinating 
  seeds. 
  Now 
  fill 
  the 
  box 
  half 
  full 
  of 
  moist 
  

   sawdust, 
  place 
  on 
  this 
  a 
  number 
  of 
  easily 
  germinating 
  seeds 
  and 
  fill 
  the 
  

   remainder 
  of 
  the 
  box 
  with 
  dry 
  sawdust, 
  held 
  in 
  place 
  by 
  tying 
  mosquito 
  

  

  netting 
  over 
  the 
  mouth 
  of 
  the 
  box. 
  Set 
  the 
  clock 
  going 
  and 
  let 
  it 
  stand 
  

   in 
  a 
  warm 
  place 
  with 
  the 
  dry 
  end 
  towards 
  the 
  stove 
  or 
  radiator. 
  More 
  

   moisture 
  may 
  be 
  supplied 
  from 
  time 
  to 
  time, 
  if 
  necessary, 
  through 
  little 
  

   holes 
  punched 
  in 
  the 
  bottom 
  of 
  the 
  box. 
  When 
  examined 
  after 
  a 
  day 
  or 
  

   two 
  the 
  roots 
  will 
  be 
  found 
  growing 
  mainly 
  towards 
  the 
  moist 
  end 
  of 
  the 
  

   box. 
  The 
  seeds 
  may 
  be 
  partly 
  germinated 
  before 
  putting 
  them 
  in 
  the 
  

   box.—

  Having 
  read 
  your 
  editorial 
  in 
  the 
  February 
  number, 
  lam 
  quite 
  of 
  

   your 
  opinion 
  that 
  an 
  American 
  conipilatory 
  work 
  like 
  that 
  of 
  Just 
  would 
  

   beef 
  great 
  value 
  to 
  botanists, 
  but 
  too 
  extensive 
  for 
  the 
  Gazette 
  But 
  

   you 
  could 
  do 
  a 
  very 
  good 
  work 
  by 
  giving 
  short 
  annual 
  summaries 
  of 
  ttie 
  

   new 
  species 
  and 
  genera 
  published 
  in 
  America, 
  with 
  references 
  indicating 
  

   place 
  of 
  publication 
  and 
  habitat, 
  as 
  has 
  been 
  done 
  since 
  the 
  close 
  of

  Every

  there 
  need

  they 
  would 
  be 
  of 
  high 
  value 
  to 
  systematic 
  botanists.

  Of
