Notes  from  the  Rural  Grounds. 
Potato  Experiments  During-  a  Dry  Season 
and  in  a  Variable  Soil. 
* 
Does  the  high-grade  potato  fertilizer  fur¬ 
nish  enough  nitrogen  ? 
* 
Does  it  pay  to  use  nitrate  of  potash  (salt¬ 
peter)  rather  than  nitrogen  and 
potash  in  other  forms  ?

Comparing  the  yields  of  the  same 
amounts  of  fertilizers,  one  with  another, 
as  was  done  in  Series  I.  and  II.,  we  shall 
see  that — 
No.  00. — Bradley  alone,  440  pounds,  yielded  383.10  bus. 
No,  00. — Bradley  alone,  880  pounds,  yielded  405.49  bus. 
No.  75.— Bradley  alone,  1 .320  pounds,  yielded  397.82  bus. 
Or  an  average  of  390.49  bushels  to  the  acre.  The 
increase  in  crop  as  compared  to  the  increase  in  the 
quantity  of  fertilizer  is  not  proportionate  or  profit¬ 
able.  In  series  1.  and  II.,  it  maybe  borne  in  mind, 
the  crop  decreased  with  the  increase  of  fertilizer. 
The  same  amount  of  Bradley  with  55 
and  110  pounds  of  nitrate  of  soda  added, 
gave  the  following  yields  ;

No.  64. — 440  pounds  Bradley  and  330 
pounds  nitrate  soda  gave  454.66  bushels 
to  the  acre,  or  71.50  bushels  more  than 
when  the  same  amount  of  Bradley  was 
used  without  any  additional  nitrate. 
While  440,  880  and  1,320  pounds  of  Brad¬ 
ley  alone  gave  an  average  of  396.49 
bushels  to  the  acre,  the  addition  to  the 
above  of  55,  110,  220  and  330  pounds  of 
nitrate  of  soda  to  the  acre  gave  an  aver¬ 
age  of  394.15  bushels  to  the  acre,  or  over 
a  bushel  less  than  the  Bradley  alone. 
In  the  first  series  the  additional  nitrate 
reduced  the  yield  20  bushels  per  acre  ;  in 
the  second  three  bushels. 
We  may  now,  as  in  the  first  and  second 
series,  compare  the  results  of  using  nitrate 
of  potash  in  place  of  the  nitrate  of  soda. 
No.  70—880  lbs.  Bradley, 
55  lbs.  nitrate  potash, 
No.  71—880  lbs.  Bradley,

The  average  yield  from  the  addition  of 
nitrate  of  potash  was  395.88  bushels  to  the 
acre,  or  1.73  bushel  more  than  the  nitrate 
of  soda  and  0.39  bushel  over  the  same 
amounts  of  Bradley  used  alone.  In  the 
first  series  nitrate  of  potash  increased  the 
yield  39  bushels  per  acre  over  nitrate  of 
soda  and  19  bushels  over  the  Mapes  used 
alone.  In  the  second  series  the  nitrate  of 
potash  increased  the  yield  over  nitrate  of 
soda,  21  bushels  and  17  bushels  over  the 
Stockbridge  used  alone. 
In  No.  78,  110  pounds  of  sulphate  of 
potash  was  added  to  1,320  pounds  of 
Bradley.  The  yield  was  but  350.16  bush¬ 
els  to  the  acre,  or  about  25  bushels  less 
than  with  either  the  Bradley  alone,  the 
Bradley  and  nitrate  of  soda  or  the 
Bradley  and  nitrate  of  potash. 
In  the  first  series  the  sulphate  gave  an 
increase  over  the  nitrate  of  soda  of  56 
bushels  and  over  nitrate  of  potash  of  16 
bushels.  In  the  second  series  the  sul¬ 
phate  gave  an  increase  over  nitrate  of 
soda  of  60  bushels  and  over  nitrate  of 
potash  of  39  bushels. 
The  fact  may  again  be  alluded  to  that 
in  the  first  series  there  were  no  rotten 
potatoes.  In  the  second  series  there  were 
81  rotten  in  the  fertilized  trenches,  two 
in  the  “  no  manure”  trenches.  In  the 
present  series  there  are  12  in  the  “no 
manure”  trenches,  58  in  the  fertilized 
trenches.  This  is  a  matter  of  little 
moment,  however,  since  the  fertilized 
trenches  greatly  outnumber  the  unfertil¬ 
ized. 
VINE  GROWTH. 
As  in  the  first  and  second  series,  the 
condition  of  the  vines  was  estimated  by 
three  persons  on  June  14,  10  denoting 
the  maximum  and  one  the  minimum  of 
size  and  vigor :

The  largest  yields,  Nos.  76,  64,  77,  61,

rated  respectively:  4%,  53^,6,  8%,  8]4i 
etc.  The  natural  fertility  of  the  soil  (in 
this  third  series)  is  shown  by  trenches 
Nos.  65,  74  and  79  averaging  281.72 
bushels  to  the  acre.  In  the  first  series 
the  average  fertility  of  the  ‘  ‘  no  manure  ”

Joseph  Harris  writes  as  follows :  “You 
talk  about  ‘  Chemicals  and  Clover  ’  as 
something  new.  We  knew  nearly  as 
much  about  it  40  years  ago  as  we  do  now. 
The  recent  discussion  about  bacteria  and 
legumes  will  probably  throw  light  on  the 
subject,  but  that  is  not  ‘chemicals.’  We 
have  always  known  that  if  we  could 
grow  good  crops  of  clover,  we  could  grow 
good  crops  of  wheat,  barley,  oats  and 
corn.  But  in  many  cases  the  trouble  is 
to  grow  the  clover.  I  am  in  hopes  that 
chemicals  and  bacteria  will  enable  us  to 
grow  good  crops  of  clover.”

Dyspepsia 
Caused  me  almost  untold  suffering.  I  felt  miserable 
and  nervous.  My  stomach  would  hardly  digest  bread 
and  milk.  But  soon  after  I  began  taking  Hood’s  Sar 
saparllla  I  had  a  better  appetite,  aud  could  not  only 
eat  well  but  had 
No  Distress  Afterward. 
I  am  so  glad  I  axn  better,  for  I  feared  I  never  should

than  ever,  and  I  tell  folks 
Hood’s  Sarsaparilla

do.  He  is  lu  mouths  old,  plump  and  fat.  and  weighs
