Manuring  of  Pice. 
Rice  is  commonly  grown  without  manure ; never- 
theless, the  manuring  of  rice  lands  has  attracted 
some  attention.  The  experience  of  C.  C.  Georgeson 
(Journal  of  the  Chemical  Society,  1889)  was  that 
there  was  considerable  difficulty  in  manuring  rice 
grown  on  irrigated  land ; but  he  had  experimented 
on  several  plots  with  ammonium  sulphate,  potassium 
carbonate  and  superphosphate  of  lime.  He  found 
that  the  best  results  followed  from  an  application 
of  these  three  compounds  according  to  the  require- 
ments of  the  plant  as  indicated  by  the  composition 
of  the  soil.  Ammonia  greatly  stimulated  the 
growth  of  the  plant,  but  did  not  increase  the 
yield  of  the  grain.  Hence,  if  ammonia  in  the 
manure  were  in  excess,  the  straw  was  increased  ; 
but  the  size  and  weight  of  the  grain  suffered. 
Superphosphate,  on  the  other  hand,  increased 
the  size  of  the  grain ; while  the  effect  of  potash 
was  intermediate  between  ammonia  and  super- 
phosphate. 
Rice  grown  on  volcanic  tufa  was  not  affected 
by  nitrogenous  manure;  but  the  yield  was 
increased  by  potash  and  superphosphate.  The 
proportion  of  grain  to  straw  was  less  than  in 
the  case  of  rice  grown  on  irrigated  land. 
Professor  0.  Kellner  and  J.  Sawano  have  ex- 
perimented on  the  manuring  of  rice.  (Journal 
of  the  Chemical  Society.)  One  set  of  experiments 
had  for  its  object  to  ascertain  whether  the  rice 
plant  preferred  its  supply  of  nitrogen  in  the 
form  of  nitrates,  or  of  ammonium  compounds. 
The  conclusion  arrived  at  was,  that  in  presence 
of  the  necessary  mineral  ingredients,  nitrates 
alone  cause  a very  slow  growth  in  the  first  few 
yeejis  of  the  plant’s  life}  but  that  latter,  the 
growth  is  normal.  Ammoniacal  compounds,  on 
the  other  hand,  stimulate  the  growth  much  ab 
first ; but  do  not  act  so  favourably  afterwards ; 
hence,  the  authors  recommended  that  the  manures 
for  rice  should  contain  nitrogen  in  both  forms.

The  Java  Coffee  Crop,  short  as  it  is  this  year, 
presents  a dark  outlook  for  next  year  owing  tolthe 
prevalence  of  leaf  disease.—  Straits  Timet. 
The  Coffee  Crip  in  Sungei  Ujong  promises  to 
be  a heavy  one.  This  in  these  days  of  high  priees 
is  a good  thing  for  looal  planters. — S.  F.  Preti. 
The  Use  of  Tea  is  yearly  increasing  at  Venice. 
The  inferior  qualities  of  Russian  teas  sold  by  many 
retailers  at  high  prioes  eannot  compare  with  the 
finest  China,  India,  and  Ceylon  teas  now  supplied 
direct  to  customers  here,  at  very  moderate  prioes. —

Export  Duties  in  Manila. — By  our  last  advises 
from  Manila  we  learn  that  there  was  expected 
to  arrive  by  Spanish  Mail  steamer  a decree  enforc- 
ing the  increase  of  export  duties  on  hemp,  coffee, 
indigo,  cordage  and  leaf  tobaoco — that  on  hemp 
alone  will  be  $2-56  per  toD,  instead  of  91'56.  The 
reason  for  this  increase  is  to  equalize  the  loss  to 
the  revenue  caused  by  the  cessation  of  the  tax  on 
coasting  trade.  Seeing  that  the  export  trade  ia 
almost  in  its  entirety  carried  on  by  foreign  traders 
and  in  foreign  bottoms,  while  the  ooaBting  traffia 
is  all  carried  by  the  nationals,  it  is  evident  the 
new  law  will  give  an  immense  advantage  to  the 
Spanish  subjects  to  the  detriment  of  tbs  foreign 
traders  generally,—  CVtina  Math
