The  Woburn  Pot-Culture  Experiments , 1909.  343 
(a)  Experiments  with  different  kinds  of  Limb  on  Old 
Pasture  ( Broad  Mead),  1910. 
Among  the  new  experiments  is  one  on  the  relative  values 
of  different  kinds  of  lime  on  old  pasture.  This  was  com- 
menced in  1910  on  Broad  Mead,  six  plots  being  marked  out 
and  dressed  respectively  as  follows  : — 
Plot  1 with  Buxton  lime  2 tons  per  acre. 
„ 2 „ Chalk  lime  2 „ „ „ 
„ 3 „ Magnesian  lime  2 „ „ „ 
„ 4 „ No  Lime 
„ 5 „ Lias  lime  2 „ „ „ 
„ 6 „ Oolite  lime  2 „ ,,  „ 
As  the  applications  were  only  put  on  in  1910,  and  as  it  will 
take  time  for  any  effects  to  show,  it  is  not  desirable  to  put  out 
the  results  obtained  for  hay  for  this  first  season. 
(b)  Potato-spraying  Experiments  ( Lansome  Field),  1910. 
An  area  of  land  in  Lansome  Field  was  put  at  the  disposal  of 
Professor  Spencer  Pickering,  Director  of  the  Woburn  Experi- 
mental Fruit  Farm,  who  carried  out  on  it  a series  of  experiments 
on  different  methods  of  spraying  potatoes  as  a preventive  of 
“ potato  disease.”  These  experiments  will  be  separately  dealt 
with  by  Professor  Pickering  in  his  Report  of  the  Fruit  Farm.
