 West-Australia.  I t  might  prove  an  advantage, to  disseminate this  
 small tree  in arid  desert-regions,  as  horses  and cattle  relish the foliage  
 amazingly.  Several other  Jaoksonias  share  the  local renown, which  
 this  congener  of  theirs  has  acquired from  its utility as a pasture-bush,  
 notably  so  the  tall-shrubby  J .   sooparia  of  South-Eastern Australia  ;  
 it  would,  therefore,  be  worth  while  to  disseminate  these  kinds  of  
 plants  in  apt  localities.

 From  India  to  Japan.  Flowers white.  Extensively  cultivated in  
 South-Europe.  I t   is  planted  in  rows  3  feet  apart.  Leek, tuberoses  
 and  similar plants  are  used,  to  occupy  the  spare-ground  for  the  first  
 year ;  1,000 plants  in  the second  year  after  grafting  produce  50 kilos  
 (about  1  cwt.)  of  flowers  in  rich  soil.  Ten  thousand  lbs.,  can  be  
 produced  on  a hectare  (nearly  2-J- acres)  ;  these  under  very  favorable  
 circumstances will  realize  a  profit  of  £230  per  annum.  Dr. Piesse  
 records,  th a t  in very  recent  times  at Grasse, Cannes  and the adjoining  
 villages  about  100,000  lbs.  of  Jasmin-flowers were gathered annually  
 for perfumery-purposes,  the  price  there  being  about  Is.  a  lb.  According  
 to  the  “ Revue  des  Sciences  Naturelles  Appliquées ”  of  May  
 1891  p.  720,  the  quantity  seems  to  have  risen  to  fully  300,000  lbs.,  
 gathered  from  the middle  of  May  to  the  end  of  June.  The  plants  
 must  be  guarded  against  frost  and  exposure  to  wind  [Dehérain].  
 May  sometimes  be  attacked  by TJromyoes  Cunuingliami  (Barclay).  
 In   France  this  jasmin  is  generally  grafted  on  J .   officinale.  The  
 bushes  are  richly manured and well watered.  Ordinary cleft-grafting  
 is  practised,  the  stock  being  headed  down  to  near  the  ground.  A  
 good workman  and assistant will  graft  about  1,000  plants  in  a  day.  
 The  delicate  scent  is withdrawn,  either  by  fixed  oil  or  fat  through  
 alcohol,  if  not required  by  itself,  or  it may be  drawn  over along with  
 oil  of  orange-peel.  The  pecuniary  yield  obtainable  from  Jasmin-  
 oultivation  seems  vastly  overrated,  even  if  inexpensive  labour  could  
 be  procured.  The  concrete  oil  is  an  article  of  commerce.  Messrs.  
 Blogg  prepare  it  in  the  following  superior  aud  expeditious manner  
 here  :  Fresh  flowers  without  stalks  are  macerated  for  some  few  
 minutes  in  deodorized methyl-chloride ;  the  liquid is  then  allowed  to  
 run off  into  a  closed  receiver for subsequent distillation ;  this maceration  
 proceeds  till  all  scent  is withdrawn by  additional  methyl  ;  the  
 distillation  is  effected  a t  a  temperature  of  only  about  86°  E.;  this  
 volatises the methyl-chloride, which when  thus  regained is  used  for  
 treatment  of  other  lots  of  flowers.  The  concrete  oil,  as  containing  
 the  perfuming  principle  in  a waxy  or  fatty  nature,  remains  behind  
 after the  evaporation  of  the  methyl,  and  is worth  about  30  shillings  
 an  ounce.  A  small  quantity  of  this  solid  substance  suffices  for  preparing  
 a  good  deal  of  the  “  essence ”  ordinarily in  use.

 Madeira.  Shrubby  like  the  rest.  Flowers  yellow.  Used  like  
 the foregoing  and  following  for  perfumery.  This  may he  prepared  
 by  spreading  the  flowers  upon wool  or  cotton,  slightly saturated with  
 olive  or  other fixed  oil,  and  covering  them with  other  layers  so  prepared. 
   The  flowers  are  renewed  from  time  to  time  until  the  oil  is  
 thoroughly  pervaded  by  the  scent, when  the  latter  is  withdrawn  by  
 alcohol.  Other modes  of extracting  the  oil  seem  feasible.

 From the  Caucasus  to  China.  Flowers white.  This  is  the  principal  
 species  cultivated  in  South-Europe  for  its  scent.  In   Cannes  
 and Nice  about  180,000  lbs.  of  jasmin-flowers  are  produced  annually  
 for  distillation  [Regel].  By  Simmonnet’s  process  the  essence  of  
 jasmin  is  solidified  as  jasminin.

 From  India  to  Japan.  I t   has  the  richest  perfume  of  all.  The  
 bush  attains  a  height  of 20  feet,  and is  almost  climbing.  The  flowers  
 are  white,  and  must  be  collected  in  the  evening  before  expansion.  
 The  relative  value  of many  other  species  of  jasmin,  nearly  all  from  
 the warmest  parts  of Asia,  seems  in  no  instance  to  have  been  ascertained, 
   so  far  as  their  oils  or  scents  are  concerned.  The  Australian  
 species  are  also  deliciously  fragrant,  amongst  which  J .   lineare,  Br.,  
 occurs  in Victorian  deserts  ;  while  also J .  didymum,  Forst.,  J .  raoe-  
 mosum,  F.  v. M.,  J .  simplicifolium,  Forst.,  J .   calcareum,  F.  v.  M.,  
 and J .   suavissimum, Lindl.,  reach  extra-tropical  latitudes.

 Southern Brazil.  A  large  tree,  likely  hardy  in  any  region  free  of  
 frost.  The  oil  of  the  seeds  serves  like  th a t  of  Ricinus, with  the  
 advantage  of  its  being  of  rather pleasant taste,  and being  required in  
 much  lesser  quantity  [Martins].  This  oil,  on  account  of  its  quickly  
 drying,  has  come  into  use  also  for  painting  in  oil-colours  [Rosenthal].

 The tall  and  stout  Coquito-Palm  of  Chili, extending spontaneously  
 to  37°  South  ;  hardy  still  in Valdivia.  Has  endured  at Montpellier  
 a winter-cold  of 10°  F.  [Count Kerohove de Denterghem].  As  hardy  
 as Pinus  Halepensis,  if not more  so  [Prof.  Sahut].  The stem reaches  
 a height of  60  feet,  and is  tinged  towards  the middle ;  the  leaves  are  
 sometimes  10  feet long.  A  kind of  treacle  is  obtained  from  the  sap  
 of this palm.  A good  tree will  give  90  gallons  of  mellaginous  sap  
 [C. Darwin].  This  is  condensed  into  a marketable  Palm-honey,  of  
 which  according  to  a  statement  in  the “ Indian Forester,” xvii., 7,18,  
 in  one  of  the  warehouses  of  Palmas  de  Ocoa,  200,000  tins  were
