greater  part  of  the  land.  But  in  none  of  the  other  establishments 
for  the  collection  of  bark  in  New  Granada  has  a  similar  practice 
been  adopted.  On  the  contrary,  beneficial  rules  are  observed 
for  the  conservancy  of  the  woods.  The  method  consists  in  leav- 
ing a  part  of  the  trunk,  about  3  feet  in  height,  whence  shoots 
may  sprout,  and  in  clearing  away  the  surrounding  trees  to  enable 
the  rays  of  the  sun  to  penetrate.  By  this  means  most  of  the 
trees  that  are  cut  down  quickly  shoot  up,  and,  the  rays  of  the 
sun  penetrating  to  the  cleared  ground,  the  seeds  which  fall  from 
the  trees  germinate  freely.  This  result  gives  us  full  confidence 
that  the  good  kinds  of  quinas  which  exist  in  this  country  will  be 
permanently  preserved. — London  Pharm.  Journ.,  Sept.  1,  1865,

ON  THE  POSSIBILITY  OF  MANUFACTURING  NEROLI  IN 
THE  BRITISH  COLONIES* 
By  J.  E.  De  Vrij. 
When  on  my  way  to  Java  in  the  month  of  October,  1857,  I 
passed  through  the  South  of  France,  my  attention  was  fixed  by 
the  large  number  of  orange  trees  cultivated  in  the  neighborhood 
of  Cannes,  Grasse,  &c,  for  the  purpose  of  manufacturing  neroli, 
which  fragrant  essence  is  exported  from  the  southern  parts  of 
France,  and  from  Italy,  to  England  and  other  northern  countries. 
The  high  price  of  this  essence  induced  me  to  inquire  if  it  would 
not  be  possible  to  manufacture  it  in  the  colony  where  I  was  going 
to  reside  for  some  years. 
A  few  months  after  my  arrival  in  Java  I  fortunately  had  the 
opportunity  of  putting  my  idea  into  practice.  In  Bandoug,  the 
town  where  I  lived,  which  is  situate  at  an  elevation  of  about  2300 
feet  above  the  level  of  the  sea,  I  was  struck  in  the  months  of  Octo- 
ber and  November  by  the  fragrant  smell  of  orange  flowers,  which 
perfumed  the  whole  neighborhood.  Upon  inquiring  the  cause, 
I  found  there  existed  in  that  part  many  thousand  shaddock  trees 
(Citrus  decumana)  whose  flowers  were  the  cause  of  the  fragrance. 
This  fact  appeared  very  curious  to  me,  for  although  the  fruit  of 
the  good  kind  of  shaddock  is  one  of  the  most  delicious  fruits  in
