 <  New  South  Wales  and  Eastern  Queensland.  Known  as  White  
 Mahogany.  I t  attains  a  considerable  height, with a  stem  reaching  4  
 feet  iu  diameter,  and is  of  rapid  growth.  The  wood  is  used  in  the  
 same  way  as  th a t  of  E.  obliqua,  but is  superior  to  it.  I t  is  heavy,  
 strong, durable, of a light colour, and has been found  good  for  palings,  
 rails,  flooriiig-hoards,  battens,  and  many  other  purposes  of  house-  
 carpentry  [Rev. Dr. Woolls].

 Cooler region  of Tasmania  only.  Seldom  attaining  a  great height,  
 but  in  this  work  not  to  be passed,  as  it  is  one  of  the  hardiest  and  
 most  antiseptic  of  all  Eucalypts.  Botanically  to  be  regarded  as  a  
 highly  developed  state  of  E.  cordata  (La  Biliardière),  but  hortieul-  
 turally  very  distinct.  Professor Balfour  observes,  th a t a  tree  of  this  
 species  has  stood  thirty  years  in  the  open  air  a t Haddington  (South  
 Scotland),  attaining  a height  of  50 feet with a  stem  8  feet  in  circumference  
 a t  the  base.  Stood  the  severest winters  in  York  and Devon,  
 when E.  siderophloia,  E.  rostrata, E. rudis perished, and E . botryoides  
 froze  to  the  ground,  but  subsequently  sent  np  strong  shoots  again  
 [Dr. Masters].  Shelter  against  hard  cold  winds  is  iu  these  cases  
 imperative  [Rev.  D.  Landsborough].  Grew  in  the  south  of  New  
 Zealand  to  20 feet in  ten  years  [Th. Waugh]. 
 E u c a ly p t u s   v im in a lis , La Biliardière. 
 South-Eastern Australia.  On  poor  soil only  a moderate-sized  tree,  
 with  a  dark rough bark  on  the trunk, and  generally known as Manna-  
 Gumtree  ;  in  rich  soil  of  the  mountain-forests  it  attains,  however,  
 gigantic  dimensions,  rising  to  a  height  of  rather more  than  800 feet,  
 with  a  stem  occasionally  to  15  feet  in  diameter.  I t   has  there a cream-  
 coloured  smooth bark, and is locally  known as White  Gumtree.  Hardy  
 a t  Arran  [Capt.  Brown].  Much  liked  in  the  frosty  regions  of  the  
 Transvaal  [Edw.  Tidmarsh].  The  timber  is  light-coloured,  clear,  
 and  though not  so  strong  and  durable  as  that  of many  other  kinds  of  
 Eucalypts,  is very frequently  employed  for  shingles,  fence-rails,  and  
 ordinary building  purposes.  I t  is stronger than  th a t  of E .  amygdalina  
 and E.  obliqua.  Weight of  a  cubic  foot  of absolutely  dry wood  about  
 43  lbs.,  equivalent to  specific  gravity  0-685.  The  honey-station  on  
 Mount  Sturgeon  depends  chiefly  on  the  flowers  of  E.  viminalis,  E.  
 rostrata,  and  E.  obliqua  for  its  bees,  the  honey  annually produced  
 being  about  ten  tons.  Sheep will  feed  on  the  foliage,  even where  
 grass  exists.  The fresh bark  contains  about  5  per  cent,  kino-tannin.  
 The  only  species,  which  yields  the  crumb-like  melitose-manna  
 copiously.  The  wood  of  this,  of  E.  globulus,  E. melliodora,  and  
 gome  others  is  occasionally  bored  by  the  larvæ  of  a  large moth, E u doxyla  
 Eucalypti,  and also  by two beetles,  Phoracantha trieuspis and  
 Hapatesus  hirtus  [C.  French].  The Phascolarctus, which lives  exclusively  
 on Eucalyptus  leaves, feeds w ith predilection on this  species.

 Eucalypts,  refer  to  an article,  partly  by  the writer  of  this  volume  as  
 contained  in  the  “ Sydney  Medical  Gazette  of  1884,”  embodying  
 also  Professor  Hosier’s  researches.  For  physical  and  chemica  
 properties of many Eucalyptus-oils refer to an elaborate original essay

 of Victoria,” December,  1893.

 The  Teosinte.  Southern Mexico  and Guatemala, up to considerable  
 elevations.  Annual.  Highly  commendable  as  a  fodder-grass  for  
 regions  free  of  frost.  A  large  number  of  stems,  sometimes  as many  
 as  90,  spring  from  the  same  root,  attaining  a  height of  18  feet.  The  
 leaves  grow  to  lengths  of _3  feet  and  form  a good forage.  In  ao-e  the  
 foliage  gets  hard,  but  still  continues  excellent  for  e n silag e .'  The  
 young  shoots, when  boiled,  constitute  a  fair  culinary  esculent.  Dr  
 Schweinfurth  harvested  a t  Cairo  from  three  seeds  in one  year  about 
 12,000  grains  ;  the  plant  requires,  about  ten  months  to  ripen  seeds  
 from  the  time  of  sowing.  Has  grown  9  feet  high  as  far  south  as  
 Cambewarra  [Thos.  Weir].  A t  Somerset,  in  Cape  Colony,  Mr.  
 Overman  obtained  a  rich  return  a t  the  end  of  Jan u ary  from  ’seeds'  
 sown  in  November.  Best  grown  as  green  crop  for  stable-fodder.  
 This  grass,  particularly  in  its  yonng  state,  is  remarkably  saccharine!  
 For.soenio growth this stately plant is also reeommendable.  Vilmorin  
 estimates  one  plant  sufficient  for  feeding  two  head  of  cattle  during  
 twenty-four hours.  Mons.  Thozet, a t Rockhampton, obtained  plants  
 12  feet  high  and  12  feet wide  in  damp  alluvial  soil,  each  with  32  
 main  stalks  bearing  nearly  100 flower  bunches.  Grqws  to  a height  
 of  15  feet  as  far  south  as  Swan-River,  aud  ripens  seeds  there  W,  
 Dale].  On  the  Clarence-River  it  also attained  a height  of  15  feet'  
 and a  plant  produced  38  shoots  [A .  Ritter].  Thrives well  in  th i  
 frostless  regions  of  South-Gippsland  [W.  H.  Lucas].  With  some  
 watering  it  grew in  the  arid  districts of  the Murchison-River  so well,  
 th a t  it  could  be  cut  thrice  in  the  season,  the  last  cutting  being  still  
 4  feet  high, and  yet  seeding well  [Isaac Tyson].  I t  should  therefore  
 prove  particularly  valuable  on  humid  banks  in  the  Australian  interior. 
   I t   is  much  quicker  in  growth  than  Guinea-Grass,  though  
 rather  slower  than  Maize,  but  lasting  longer  for  green  fodder,  and  
 not  so  hardy  as  Sorghum.  I t   is  essentially  a  summer  grass.  Its  
 growth  can  be  continued  by  cutting  the  tufts  as  green  fodder ;  thus  
 tender  food is  continued  ;  it  does  not cause  colic  to  horses and  cattle.  
 As  a  forage-plant  it  is without  a  rival  in warm  climes.  I t   can  also  
 be  readily dried  for hay.  I t   likes humid  soil  best, and resists  intense
