ceptible,  especially  if  the  wheat 
is  sown  late  and  is  a thin  plant. 
Wheat  after  wheat  is  almost 
sure  to  have  it ; the  same  after 
a naked  fallow.  I never  saw  it 
in  wheat  after  oats ; nor  on  thin- 
skinned  poor  clay,  however 
much  out  of  condition  it  might 
be.  There  is  no  sort  of  wheat 
proof  against  the  disease,  unless 
it  be  the  Old  Rivett’s.

Very  subject, 
and  espe- 
cially 1881- 
1882. 
Mildew  is  always  found  after 
severe  spring  frosts.  Have  never 
tried  thin  sowing;  but  if  by 
any  accident  the  plant  is  thin, 
the  chances  of  mildew  are  much 
increased.  The  land  heavily 
clayed  suffered  in  1881,  hut  not 
nearly  so  much  as  those  lands 
where  claying  had  been  ne- 
glected.

On  my  farm 
and  in  this 
district  the 
disease  sel- 
dom occurs 
to  any  seri- 
ous extent. 
In  1881  a field  of  50  acres  was 
injured  in  my  estimation  to  the 
extent  of  2 coombs  an  acre. 
The  farm  is  open  and  exposed ; 
it  lies  below  high-water  mark. 
The  soil  is  deep-stapled  loam. 
The  crop  in  question  followed- 
clover, > partly  mown,  partly 
grazed.  No  manure  was  applied, 
but  the  sheep  were  fed  with 
cake.  Square  Head  wheat  was 
sown  Nov.  5,  6,  9,  the  usual 
season.  The  crop  came  up  thin, 
but  filled  up  into  a very  fine  crop. 
Land  in  a high  state  of  fertility 
is  most  liable.  We  never  see  a 
trace  of  the  disease  after  oats.

Not  subject  to 
malignant 
attacks. 
Where  soils  contain  a superabund- 
ance of  organic  matter  in  a raw 
or  crude  state,  and  the  crop  is 
exposed  to  continuous  rains, 
with  damp  atmosphere,  condi- 
tions most  favourable  to  the 
development  of  mildew  seem  to 
be  present.  Thin-sown  crops 
are  more  predisposed  to  attack 
than  those  which  are  thicker.
